Interpretive Summary:

Technical Abstract: Polymer coatings of both acid delinted and machine delinted cotton seed have been effective carriers for chemical and biological seed treatments. In field comparisons of three polymer coatings, Incotec, Colorcon, and Seedbiotics, applied to both acid delinted and machine delinted Acala Maxxa seed, all were similar based on percentage seedling survival. Combinations of fungicides were mixed with the polymer coatings before application to the seed. When seed treatments were made using acid delinted seed, the preparations of biocontrol fungi mixed with the Colorcon or Seedbiotics polymers, were as effective as chemical seed treatments based on percentage seedling survival and lint yields. In greenhouse tests, Binab T (Trichoderma harzianum + T. polysporum), was effective both as a seed treatment or with in-furrow applications for controlling black root rot caused by Thielaviopsis basicola.
