• NU-COP® 30 HB is powered by HiBIOTM technology that improves coverage of the product by creating a smaller, consistent particle size to create a slow release copper ion (Cu+2).
• Highly effective, low-dust copper formulation that delivers a 30% metallic copper content which results in superior rain fastness.
• NU-COP® 30 HB delivers more bioavailable copper ions that provides excellent disease control.
• NU-COP® 30 HB can be applied by ground, aerial or through approved chemigation equipment.
• NU-COP® 30 HB is OMRI certified and can be used in organic production systems.

- 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® 30 HB 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® 30 HB for each crop in sufficient spray water for thorough coverage of the crop to be sprayed.

FROST INJURY PROTECTION
Bacterial Ice nucleation inhibitor – Application of NU-COP® 30 HB 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 weather conditions favor severe frost.

Additional applications may be necessary when frequent rainfall occurs. Thorough coverage of catkins, leaves and nutlets is essential for effective control. When applied as a dilute spray, 1 pint of summer oil emulsion may be added per 100 gallons of spray.
