WHAT IF I HAVE A LONG-TERM (i.e. 3 YEAR) COTTON ROTATION?
The primary goal of AF36 applications is to reduce aflatoxin contamination in the treated crop. In many cases, these initial aflatoxin reductions result in cottonseed with improved access to markets. However, the long-term goal is to gradually reduce the risk of contamination across our production areas by reducing the incidence of aflatoxin producers. Early studies in Yuma County demonstrated that AF36 persists at elevated levels in the soil for more than two years after application. While back to back AF36 applications may produce more dramatic results, treatment of cotton even in long rotations serves to gradually reduce the aflatoxin producing potential of resident fungi across the entire area. This is the long-term goal of AF36 use.
