Amides (chloroacetamide and others)
Injury from amide herbicides is more prevalent on sandy soils with low organic matter. Additional conditions that may increase the potential for injury are deep planting, cool, wet conditions and/or soil crusting. Management options to consider with hybrids with less tolerance to chloroacetamides are listed below:
The potential for crop injury from benzoic acid or phenoxy herbicides increases when the hybrid is under stress and/or the hybrid is sprayed at a late stage of growth. The additional management suggestions below are helpful in reducing potential for injury:
Isoxazole (HPPD Inhibitors)
Injury from sulfonylureas is more likely when the corn is sprayed after the plant is 10-12 inches tall and/or the plant is exposed to a stress, such as cool, dry conditions. Additional management suggestions when applying sulfonylureas are:
