- Applications
- Applicable Crop
- Application Technique
- Applying Spray Mixture
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® 50 DF 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® 50 DF for each crop in sufficient spray water for thorough coverage of the crop to be sprayed.

Bacterial Ice nucleation inhibitor – Application of NU-COP® 50 DF made to all crops listed at rates and stages of growth indicated on the label at least 24 hours prior to anticipated frost conditions will afford control of ice nucleating bacteria (Pseudomonas syringae, Erwinia herbicola and Pseudomonas fluorescens) and may thereby provide some protection against light frost. The degree of frost protection will vary with weather conditions and other factors. Not recommended for those geographic areas where weathaer conditions favor severe frost.

Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwater or rinsate.
Storage & Handling
- Storage and Disposal
Do not contaminate water, food, or feed by storage or disposal.
PESTICIDE STORAGE: Store in a cool, secure, dry area in original container.
PESTICIDE DISPOSAL: Pesticide wastes are acutely hazardous. Improper disposal of excess pesticide, spray mixture, or rinsate is a violation of Federal law. If these wastes cannot be disposed of by use according to label instructions, contact your State Pesticide or Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for guidance.
