GMO Testing in Organic Cotton: What Farmers Need to Know

Organic cotton farmers work hard to maintain their certification, ensuring that their crops are grown without synthetic chemicals, genetically modified organisms (GMOs), or prohibited inputs. Even when farmers follow organic practices to the letter, GMO contamination can still occur!

Let’s take a closer look at how GMO testing works, what the results mean, and why the final decision on certification can sometimes feel arbitrary.

How is GMO Contamination Measured?

GMO testing in Seed Cotton (raw cotton including fibers and seeds) is performed using real-time PCR analysis, a widely used method to detect genetic modification markers in cotton DNA. The gin will take samples of your seed cotton and submit those samples to their Global Organic Textile Standard (GOTS) Certifier. The GOTS Certifier will submit those samples to a lab, usually OMIC which will then run them for GMO presence. The results are then submitted back to the GOTS Certifier. Here are some things that are being investigated.

  • Standard Limit of Quantification (LOQ): 0.1% GMO content – This is the most commonly used threshold for accurately measuring contamination.
  • More Sensitive Tests: Some advanced labs claim they can detect levels as low as 0.01%, but I have not seen this as an industry-standard threshold for Seed Cotton testing. But you could see this from European labs!
  • Anything above a 0.1% is detectable and reported as such as you can tell from this test sheet with all the names removed!

Here is another test with some different results.

What the Test Results Mean

  • This sample contains GMO markers including Bt toxin (Cry1Ab/Ac) and herbicide resistance (otp/mepsps).
  • p35S, pFMV, and tNOS confirm genetic modification.
  • Organic certifiers would likely reject this cotton since GMO elements were clearly detected.
  • If contamination was unintentional, an investigation might be needed to determine if the cotton can still qualify for certain supply chains.
MarkerDetected?GMO Trait Significance
SAH7 (Cotton Gene)✔ YesConfirms valid cotton DNA
Cry1Ab/Ac (Bt Toxin)✔ 1.44%Indicates Bt Cotton (Insect Resistance)
otp/mepsps (Glyphosate Resistance)✔ 0.47%Possible Roundup Ready Cotton (Herbicide Resistance)
p35S (CaMV Promoter)✔ 1.93%Common GMO activation switch
PAT (Glufosinate Resistance)❌ Not DetectedNo Liberty Link herbicide resistance
pFMV (FMV Promoter)✔ 1.91%Used for GMO gene activation
tNOS (Terminator)✔ 3.27%Common GMO terminator sequence
GM Elements (General GMO Presence)✔ YesConfirms GMO modification detected

Now What Happens?

What happens when an organic cotton sample tests positive for GMOs? That really depends on a lot of different things, and this is where farmers can get frustrated. I have provided you with some sample test results but usually you won’t even see these results. At this point the GOTS Certifier for the Gin has your test results. This is a small list of what they do:

The Global Organic Textile Standard (GOTS) Says:

  • No intentional use of GMOs is allowed.
  • If contamination is detected, the GOTS certifier launches an investigation instead of outright rejection.
  • If the farmer can prove they used verified non-GMO seed and followed organic practices, then there is a strong possibility that they may still be approved.

GOTS Certifier Reaches Out

The next step is for the GOTS Certifier to reach out to your Organic Certifier at the farm level. Because a “red flag” is now waving, your certifier is going to be looking at your Organic System Plan (OSP) with a fine-toothed comb! They will be looking at your cottonseed information, at your field and field locations, at every record you submitted to determine if there is anything that might have caused a “voluntary” versus “involuntary” contamination. You will probably know that something is up either by just a notice of an investigation or possibly a full-blown visit. Either way, they (your certifier) are trying to find out why the raw seed cotton is showing up with detectable levels of GMO.

Most of the time there is absolutely nothing you did to cause a detectable limit of GMO in your seed cotton. We might call this an “Act of God” because no one knows why it happens. The planting seed tested good, the field was good and there is no drift. No one knows what happened or why and so you get a clean bill of health. The system is designed with some flexibility because there can be an “Act of God” and to be honest I am glad to recognize that God is Sovereign even over cotton fields and cotton farmers!

On the other hand, it can sometimes be identified as a wrong bag of planting seed picked up, a wrong module or bale marking, or some other contamination issue along the way. Elevated levels of GMO in your raw seed cotton will throw up all kinds of red flags and could lead to a non-compliance, rejected organic cotton and a microscopic look at all other aspects of your organic operation! Let’s hope we don’t go there……

What Can Farmers Do?

  • Test early and often. If you suspect contamination, conduct your own tests before sending cotton to market. Newsletter Article Page 2
  • Maintain strong records. Prove that you sourced verified non-GMO seed and followed organic protocols.
  • Work with a certifier who understands the realities of farming. Some certifiers are more flexible in their investigations than others or ask the right questions instead of just assuming you are wrong.
  • Improve segregation. Make sure that cotton stays separate at every stage, from harvesting to ginning.

Final Thoughts

Organic farmers face an uphill battle when it comes to avoiding GMO contamination. Even with perfect compliance, your cotton test results can find GMOs, and certification decisions often depend on factors beyond the farmer’s control. Don’t panic and be willing to go the extra mile to find out why. Your organic certifier has their neck on the line too as does your ginner and we all want you to succeed. As we are at the very start of a new crop year do all you can now to stay out of this “mess” later!

Organic Sorghum Resources (update)

Sorghum’s natural characteristics and compatibility with organic farming principles indeed make it an excellent crop for organic cultivation. While some traits like drought tolerance and non-GMO status are shared with conventional sorghum, these characteristics synergize particularly well with the goals and methods of organic agriculture, offering distinct advantages.

Sorghum’s Advantages

  • Drought Tolerance: Sorghum’s inherent drought tolerance makes it an ideal crop for organic systems, which prioritize water conservation and efficient use.
  • Low Fertilizer Needs: Sorghum’s ability to thrive in less fertile soils matches well with organic farming, which relies on natural fertility management rather than synthetic fertilizers.
  • Natural Resistance to Pests and Diseases: Sorghum’s inherent resistance to many pests and diseases minimizes the need for synthetic pesticides, making it easier for organic farmers to manage their crops.
  • Versatility in Use: Sorghum can be utilized in a variety of ways (grain, syrup, fodder) which allows organic producers to cater to diverse markets (food, feed, sweeteners) under organic labels.
  • Contribution to Soil Health: Sorghum’s deep rooting system can improve soil structure and increase water infiltration, beneficial effects that are particularly valued in organic systems focused on long-term soil health.
  • Crop Rotation and Diversity: Sorghum fits well into crop rotations, a cornerstone of organic farming, helping break pest and disease cycles and improving soil health without relying on chemical inputs.
  • Consumer Preference for Non-GMO: Even though there is no GMO sorghum on the market, the strong consumer preference for non-GMO products benefits organic sorghum producers, as their products are guaranteed to meet this demand.
  • Growing Demand for Organic Grains: The increasing consumer demand for organic products extends to grains, including sorghum, for both human consumption and organic animal feed.
  • Carbon Sequestration: Sorghum’s growth habit and biomass production can contribute to carbon sequestration, aligning with the environmental sustainability goals of organic farming.

While many of sorghum’s traits benefit both conventional and organic systems, its natural resilience, low input requirements, and versatility make it particularly well-suited for organic agriculture. These characteristics help organic sorghum producers minimize reliance on external inputs, align with organic principles, and tap into a growing market demand for organic products.

Buying seed?

The number of seeds per pound in sorghum varieties can vary significantly depending on the specific variety and the size of the seeds. Generally, this range can be broad, reflecting differences in genetics, breeding objectives, and end use (grain, forage, or specialty types). Here’s a general overview:

  • Small-Seeded Varieties: Can have as many as 16,000 to 18,000 seeds per pound.
  • Large-Seeded Varieties: May have fewer seeds per pound, typically ranging from 12,000 to 15,000 seeds per pound.
  • Forage sorghums and sorghum-sudangrass hybrid types tend to have larger seeds compared to grain sorghum varieties. The seeds per pound can range from 10,000 to 14,000 for forage types, with sorghum-sudangrass hybrids often on the lower end of this scale due to their larger seed size.

Sorghum Varieties

The varieties listed below are some planted by current organic growers. We are in the process of getting a better list together and will post them here!

These varieties are listed along with their respective websites for more detailed information. Company listings are down below and your source for qualified salespeople. Check with your certifier before buying any sorghum seed especially if the variety is not sold as organically produced. Since we do not have many organic, locally adapted sorghum varieties producers typically buy conventionally produced varieties without seed treatments.

FieldWatch is Here in Texas!

FIELDWATCH® WELCOMES TEXAS AS ITS 27TH STATE MEMBER

by Curt Hadley, Field Watch

FieldWatch, Inc., a non-profit company that promotes communication and stewardship among crop producers, beekeepers and pesticide applicators, announces that Texas has joined as the 27th member state.

Texas joins FieldWatch along with 26 other states, one Canadian province and the District of Columbia. The membership will enable Texas’ beekeepers (hobbyist and commercial) and crop producers (organic and conventional) to use a secure, easy-to-use online registry to identify and map the locations of apiaries and crop fields that pesticide applicators should avoid. The free and voluntary registries, DriftWatch™ and BeeCheck™, will be available to all Texas beekeepers and crop producers. FieldCheck® is the online and mobile portal that pesticide applicators can use to improve decision-making and avoid damage from spray drift to crops and beehives.

“The goal is to get beekeepers and crop producers registered through FieldWatch, so applicators can access accurate information before spraying,” said Bob Walters, President and CEO of FieldWatch. “This model has been proven to build stewardship and communication in agriculture.”

Texas’ membership decision was especially driven by the needs of crop producers and beekeepers who wanted to register the locations of their apiaries and crops.

This map shows that we have 2 bee sites approved and now one organic cotton site approved. Simple and easy! If you have any questions or concerns, just email me: bob.whitney@ag.tamu.edu

Texas Organic Rice Update: Insights for Producers and Researchers

Great picture by USA Rice at the recent Western Rice Conference, January 15th in El Campo.

Organic rice production in Texas continues to evolve, with advancements in weed control, fertility management, and ratoon cropping showing promising results. This update covers the latest developments, challenges, and resources available to organic rice growers, with implications for both organic and conventional production systems.

Advancements in Organic Rice Production

1. Enhancing Yields with Ratoon Crop Production
Texas researchers are leading efforts to improve ratoon crop yields in organic rice. This practice of harvesting a second crop from the stubble of the first offers a sustainable way to maximize productivity without replanting, making it an attractive option for organic farmers. Paragraph from study below:

“To enhance nitrogen availability, the researchers utilized organic-approved inputs such as compost and cover crops, finding that an equivalent of 90 pounds of nitrogen per acre was optimal for achieving the greatest yields, with greater rates offering no additional advantage. This insight helps farmers optimize nitrogen inputs using sustainable sources, saving costs while promoting organic practices.”

2. Organic Variety Trials – 2023
Organic variety trials conducted in Garwood, Texas, showed promising results. These trials not only help identify suitable varieties for organic systems but also aid in improving overall seed supply for future seasons.

RT73027263161.444.8
XL7236760150.241.7

Overcoming Challenges in Organic Rice Production

1. Weed Control Innovations
Weeds remain a major challenge for organic rice farmers. Here are some key tools and practices being used:

  • Northern Jointvetch Control: The bioherbicide LockDown (Colletotrichum gloeosporioides f. sp. Aeschynomene) has shown great effectiveness. This live organism must be applied with a surfactant, offering a cost-effective solution.
  • Hemp Sesbania Management: USDA-approved use of Albifimbria verrucaria (formerly Myrothecium verrucaria) has demonstrated success against hemp sesbania and other weeds like sicklepod and pigweed.
  • Water-Seeding Method: The pinpoint flood system effectively suppresses weedy rice by creating anaerobic conditions that inhibit germination.

2. Organic Fertility Programs
Organic rice growers are adopting long-term fertility strategies, including the use of compost and biostimulants. Research highlights the importance of repeated compost applications to boost soil biological activity and improve yields.

  • Biostimulants in Focus: Biostimulants such as humic acids, seaweed extracts, and microbial inoculants can enhance plant growth. However, product quality remains inconsistent, necessitating thorough testing and careful application.

Market Trends and Opportunities

The organic rice market faces challenges related to supply chains, international competition, and fraud. Key issues include:

  • GMO concerns, especially in Mexico and China.
  • Limited seed supply due to adverse weather conditions in 2024, which impacted production in Texas.

Picture of an article in an Indian News Post showing “GMO” rice sent to Europe!

Despite these hurdles, Texas continues to work to expand organic rice production. Programs like the Transition to Organic Partnership Program (TOPP) are equipping farmers with mentorship, community-building opportunities, and technical training to support successful transitions to organic farming.

Resources for Organic Farmers

Texas A&M AgriLife Extension Organic Program provides a range of resources to support organic rice growers:

  • Podcasts: On TOPP of Organic offers insights into organic production practices.
  • Newsletters: Subscribe to bimonthly and monthly newsletters for the latest updates.
  • Workshops and Field Days: Covering topics such as certification, conservation planning, and marketing.

The Future of Organic Rice in Texas

Organic rice production has been a rapidly growing industry with vast potential but there are plenty of struggles right now. By addressing challenges like weed control and fertility management, and leveraging mentorship and research programs, Texas farmers can lead the way in sustainable and organic agriculture.

Lastly, this information is from Cognitive Market Research off their website. I took a picture of this graph showing that Organic Rice sales are growing tremendously and will continue to grow. I have rice growers say to me that people have quit buying organic rice and they believe this because our organic rice farmers can’t get contracts to grow organic rice. The problem is not that our US consumers don’t buy organic rice it is that organic rice imports are filling that demand – NOT Texas organic rice producers! So, I ask the question, “Where is this organic rice coming from?”

Addressing the Challenges of Organic Cotton Seed

As the Extension Organic Specialist with Texas A&M AgriLife Extension Service, I work closely with organic cotton farmers to navigate the complexities of maintaining organic certification. Recently, issues surrounding the sourcing and certification of organic cotton seed have come to the forefront, particularly with the influx of imported planting seed from other countries. This situation is compounded by the stringent requirements of the Global Organic Textile Standard (GOTS) and potential conflicts in international trade.

Key Issues with GOTS and Organic Cotton Seed

Contamination Risks

GOTS certifies cotton fiber from the gin facility to the mill but does not extend this certification back to planting cotton seed. This poses a significant risk for farmers, as even with rigorous adherence to organic practices, their crops can become contaminated through cross-pollination, especially in regions like the cotton belt where GMO crops are prevalent. Contamination, detected in seed cotton samples at the gin before ginning (raw cotton from the farm), can lead to farmers being excluded from organic certification for up to five years, creating severe economic and operational challenges.

Lack of Standardized GMO Thresholds

Currently, GOTS does not establish a GMO contamination threshold for cotton seed, which complicates the situation for organic cotton farmers. While many USA cotton seed companies work to maintain low levels of GMO contamination (usually below 5%), GOTS demands strict purity in the final product. This standard requires seed cotton (seed, leaves, stems) testing because it is the only part of the cotton plant containing DNA, where contamination can be detected. However, this rigid approach does not fully account for the post-planting natural cross-pollination risks that farmers face, such as GMO pollen carried by insects into organic fields. This discrepancy between the ideal purity GOTS seeks and the realities of farming highlights the need for a practical and fair standard that supports organic farmers without penalizing them for uncontrollable factors.

To address these challenges, a multi-faceted approach involving key industry stakeholders is essential. Here’s how we can move forward:

1. Establishing a Fair GMO Contamination Standard: 

Implementing a reasonable GMO contamination threshold for planting cotton seed would significantly alleviate the testing burden on farmers and prevent unjust penalties. This standard should be recognized and enforced by all organic certification bodies, including GOTS. If the plants grown from this approved cotton seed are tested and not the seed cotton at the gin the farmer would be protected from the natural potential of seed contamination.

2. Enhanced Collaboration Among Industry Stakeholders: 

Seek advice and input from the industry, including farmers, Extension specialists, researchers, ginners, and manufacturers, to determine acceptable thresholds and protocols based on constraints faced by each group. This collaborative approach ensures that the standards are practical and attainable.  We, here in Texas, represent the largest cotton production area in the world and want to be involved in this process.

3. Advocating for Policy Changes:

Engaging with policymakers and certifiers to establish upfront certification for cotton seed would ensure farmers have a clear understanding of the seed quality they are purchasing. Specific policies might include establishing minimum GMO thresholds and clear guidelines for contamination levels, mitigating risks, and supporting farmers in maintaining their organic certification. With upfront testing by seed companies and certifications from USDA, gins could operate more confidently, alleviating the burden not only on farmers but also on the ginning facilities themselves.

Addressing Import Issues

The reliance on non-GMO cottonseed imported from other countries, while possibly beneficial in the short run, introduces additional complications. Political and economic instability can disrupt supply chains, and without stringent testing, the risk of unintended contamination remains. Developing robust testing protocols, such as frequent sampling and standardized testing methods, for all imported seed is crucial to ensure they meet the same standards required domestically. It will also create a more transparent, open and balanced business environment for all.

Conclusion

The path to resolving these issues is through collaboration, standardization, and proactive policymaking. By working together, we can create a fair and sustainable environment for organic cotton farmers, ensuring their efforts are recognized and supported throughout the supply chain.

Observations on Bindweed Gall Mites: Field Updates and Future Plans

If you had a chance to read my previous post about applying Bindweed Gall Mites in July, the picture above will make more sense! This marked area, indicated by the flag, is where we scattered pieces of field bindweed infested with Bindweed Gall Mites sourced from the insectary in Colorado. Following the application in July, we endured one of the hottest and driest August months on record, leading us to assume that the mites had perished. While the bindweed in this area appeared dead due to the drought, we knew from experience that field bindweed rarely succumbs to such conditions.

In September, the weather shifted with some much-needed rain. The field bindweed plants sprang back to life, looking healthy once again. Unfortunately, our initial assumption was that while the bindweed survived, the Bindweed Gall Mites did not.

Fast forward to Monday, December 9th. After receiving a call from Carl Pepper the previous Friday urging me to visit the field, I was met with a surprising sight. The flag in the photo marks where the mites were introduced back in July. Surrounding the flag is a somewhat circular pattern of dead or dying bindweed, while outside this area the bindweed appears alive and healthy. To the left edge of the photo, some bindweed remains slightly green, but below and beyond the flag the plants look unmistakably dead. This circular pattern extends outward, as highlighted by the line drawn across the photo.

One might argue that this is merely a drought-affected patch. However, we placed a second batch of Bindweed Gall Mites in another area of the field, and a similar circular pattern has emerged there as well. These mites are so tiny that they are invisible to the naked eye, but in the lab, Dr. Kyle Slusher, an Extension Entomologist in our office, identified galls on collected bindweed plants under magnification.

Future Plans for Bindweed Gall Mites

Our immediate hope is to see the affected areas of bindweed continue to decline. While we don’t expect the mites to eradicate the bindweed entirely, a balance is desirable to ensure the mites’ survival. Looking ahead:

  • Field Monitoring: We’ll continue observing the affected areas to assess long-term impacts.
  • Laboratory Work: Dr. Slusher plans to conduct further studies on the mites in a controlled lab environment.
  • Farmers’ Interest: Several local farmers have expressed interest in this biological control method and plan to collect infested bindweed from this field to introduce on their farms.
  • Suitability for Dry Climates: The mites’ preference for hot and dry conditions aligns well with the West Texas climate, making this an intriguing and potentially effective solution for bindweed management in the region.

This project represents a promising step in biological pest control for field bindweed, and we’re excited to see how this progresses both in the field and through collaboration with area farmers. A big thanks to Carl Pepper for allowing us to experiment with this novel insect and to continue monitoring progress!
