Our Reaction: The service is aware that of many seed treatments are commonly used to own corn and soybean vegetation. The new EPA’s exposure evaluation processes for comparing crushed software and seed products solutions is a lot like its examination to possess foliar programs, apart from exposure off contact publicity is not analyzed (EPA 2014 p. 10). Brand new EPA claims, To possess crushed software, its generally thought you to definitely publicity from honey bees of direct exposure to the fresh pesticide are restricted, given the character of your own software to help you exposed surface, even though conditions might occur in the event that apps are available having bee-attractive weeds present.
