Peanut Seedling Test Plot

Today (May 20) we finished planting a peanut seedling disease test plot at the Texas A&M AgriLife Research Center in Stephenville. In this test we are looking at 10 different treatments for seedling disease control on untreated peanut seed.

Conventionally (not organic) peanut seed is treated with a fungicide that protects the seed and the young seedling from any of the common fungus diseases found in soil. Seed treatments are really beneficial in situations where the conditions are not very good for germination like cold, wet weather. In an organic system with untreated organic seed, you basically need to wait till the weather is better or maybe you discover some organic treatments you can use when you plant, like in this test. What we are doing is testing some organic seed treatments (applied to the seed before planting), some liquid in-furrow treatments, and some soil incorporated treatments and comparing them with an untreated check (just peanut seed) and a check with a regular conventional fungicide treated seed.

Over the course of the next several weeks we will be evaluating the germination percentage for each of the 400 seed planted in each treatment, how quickly they grow, and the stage of plant at each week. Below are the products used and the treatment method: IF = in-furrow, seed is a seed treatment sprayed on to wet and then dried, incorporate into beds before planting.
