Nu-Cop® 50DF

Active Ingredient: Copper Hydroxide

10 lb; 20 lb

Nu-Cop® 50DF inhibits fungal spore germination and mycelial growth through the release of free copper ions (Cu+2) from the applied fixed copper. On most crops, sprays can be applied with conventional dilute sprays in aerial application unless specifically prohibited on the label. Recommended use rates are generally stated in lbs. of Nu-Cop® 50DF per acre sprayed. When using each type of sprayer, follow that equipment manufacturer’s recommendation, or that of the State Extension Service for the volume of spray water per acre on each crop. Mix the recommended lbs. of Nu-Cop 50DF for each crop in sufficient spray water for thorough coverage of the crop to be sprayed.
