Diablo is a herbicide containing 49.41% Dimethylamine Salt of Dicamba (3,6-dichloro-o-anisic acid). It is designed for weed control in various crops including corn, cotton, sorghum, small grains, pasture, hay, rangeland, fallow, sugarcane, asparagus, and turf or grass seed crops. It can be used for both preemergence and postemergence applications depending on the specific crop and weed target. The product is effective against a wide range of annual, biennial, and perennial broadleaf weeds. When applying to corn, it can be used as an overlay treatment. Users must be cautious with sensitive crops and avoid application during windy conditions or when temperatures are expected to exceed 85°F to prevent crop injury. The label provides specific instructions for mixing with water or sprayable liquid fertilizer. Always follow engineering controls when using closed systems or aircraft. Note that this product can leach through soil into groundwater, especially in permeable soils with shallow water tables.
