Active materials

Maestro D is formulated as an emulsifiable concentrate of octanoic acid ester of bromoxynil containing the equivalent of 2 pounds of bromoxynil per gallon and 2,4-Dichlorophenoxyacetic acid containing the equivalent of 1.9 pounds per gallon. Maestro D is a selective postemergence herbicide for control of important broadleaf weeds infesting Small Grains (Wheat, Barley, Oats, Rye and Triticale), Corn (Field Corn and Popcorn), Sorghum (Grain and Forage), Fallowland and Conservation Reserve Program (CRP) Acres. Optimum weed control is obtained when Maestro D is applied to actively growing weed seedlings. Maestro D contains a contact herbicide and a systemic herbicide, therefore thorough coverage of the weed seedlings is essential for optimum control.
Maestro D has little residual activity. Therefore subsequent flushes of weeds will not be controlled by the initial treatment. Generally crops that form a good canopy will help shade subsequent weed flushes. However, certain crops or short-straw varieties, for example Yecora Rojo wheat, may not develop the crop canopy fast enough to shade the subsequent flushes of weeds.
Occasional transitory leaf burn may occur. The temporary leaf burn is similar to that seen with liquid fertilizer. Recovery of the crop is generally rapid with no lasting effect. Frequency and amount of leaf burn may be greater when crops are stressed by abrasive winds, cool to cold evening temperatures or mechanical injury, such as that caused by hail, sleet or insect feeding. To reduce the potential for temporary leaf burn, applications should be made to dry foliage in the specified spray volumes per acre when weather conditions are not extreme.
