GOT GREEN?

NOW IS THE TIME TO APPLY HARVEST DESICCANTS. Desiccants can help accelerate soybean harvest by turning green plants brown, as well as killing weeds. If you plan to use a harvest aid, however, timing is critical. Applied too soon, a harvest aid can reduce soybean yield. Applied too late, and there will not be enough time between its application and the earliest time harvest can occur.

THERE ARE TWO ACCEPTABLE METHODS TO TIME APPLICATION OF A HARVEST DESICCANT: Method 1: According to the label on a commonly used harvest-aid product, Gramoxone Inteon, harvest desiccants should be applied to indeterminate varieties when 65 percent of the pods have reached a mature color or when seed moisture is 30 percent or less. For determinate varieties, apply when plants are mature or when beans are fully developed, 50 percent of the leaves have dropped and remaining leaves are yellowing.

Method 2: Desiccants can also be applied when the average seed moisture content is 40 percent or lower, roughly at the R6.5 growth stage. According to research conducted at Louisiana State University Ag Center, applying the harvest aid at 40 percent seed-moisture content will result in earlier harvest and will not reduce yield. This may be outside what is recommended on common labels, but the LSU research determined that waiting until seeds are drier than 40 percent moisture content will not allow the necessary time between its application and the earliest time harvest can occur.
