Effect on Soybean Yield When Phytotoxicity is Observed Growers using preemergence PPO herbicides may experience low levels of phytotoxicity when cool and wet conditions are present during emergence. Crop injury may appear troublesome when first observed, however soybean plants recover quickly and demonstrate strong yield results (see charts below). In most cases yield is not affected, and growers may actually experience an increase in yield with Fierce® Herbicide over competitive PPO herbicides, due to the superior weed control provided by Fierce .
