• NU-COP® 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 has a high metallic copper content and provides superior rain fastness.
• NU-COP® HB delivers more bioavailable copper ions that provides excellent disease control.
• NU-COP® HB can be applied by ground, aerial or through approved chemigation equipment.
• NU-COP® HB is OMRI certified and can be used in organic production systems.

Applications & Uses

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

Bacterial Ice nucleation inhibitor—Application of NU-COP® 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.
APRICOTS
DISEASE Application Rate (lbs of product/Acre) Minimum Days Retreatment Interval COMMENTS Fall and Late Dormant:
Anthracnose
European Canker
Pseudomonas Syringae
6.0–12.0
Only one dormant application allowed per season Apply before fall rains.
Use the higher rates when conditions favor disease.
Use on yellow varieties may cause discoloration. To avoid, pick before spraying.
Bloom/Growing Season:
Coryneum Blight (Shot Hole)
Blossom Brown Rot
3.0 5 Apply at popcorn to full bloom as a full cover spray. To avoid spray injury, do not apply after full bloom.
RESTRICTIONS Maximum single dormant application rate is 12.0 lbs/A (6.0 lbs. metallic copper equivalent)
Maximum single bloom/growing application rate is 3.0 lbs/A (1.5 lbs. metallic copper equivalent)
Maximum annual application rate is 36.0 lbs/A (18.0 lbs metallic copper equivalent)
PEACHES & NECTARINES
DISEASE Application Rate (lbs of product/Acre) Minimum Days Retreatment Interval COMMENTS Dormant and–Late Dormant–to Pink Bud Season:
Bacterial Spot
Leaf Curl
Coryneum Blight (Shot Hole)
4.0–8.0
7 Apply at leaf fall as dormant application.
Use the higher rate when rainfall is very heavy and disease pressure is high. May be used with an agricultural spray oil.
Bloom/Growing Season:
Coryneum Blight (Shot Hole)
Blossom Brown Rot
4.0–6.0
7 Apply as a full cover spray at pink bud. (Application at this time also affords some control of Leaf Curl and Coryneum Blight).
Note: Do not spray later than three weeks prior to harvest. Do not use at rates above those recommended.
Bloom/Growing Season:
Bacterial Spot
0.5–2.0
5 Post-bloom application applied at first and second cover sprays.
Note: Do not spray three weeks prior to harvest. Spotting of leaves and some defoliation may occur from use in post-bloom cover sprays.
RESTRICTIONS Maximum single dormant season application rate is 8.0 lbs./A (4.0 lbs metallic copper equivalent)
Maximum single growing season application rate is 3.0 lbs./A (1.5 lbs metallic copper equivalent)
Maximum annual application rate is 36.0 lbs./A (18.0 metallic copper equivalent)

GRAPES
DISEASE Application Rate (lbs of product/Acre) Minimum Days Retreatment Interval COMMENTS Black Rot
Powdery Mildew
Downy Mildew
Phomopsis

3 Begin applications at late dormant up to bud break with subsequent applications throughout the season depending upon disease severity.
NOTE: Foliage injury may occur on copper sensitive varieties such as Concord, Delaware, Niagara, and Rosettes. Either test for sensitivity or add 1 to 3 pounds of hydrated lime per pound of Nu-Cop® HB.
RESTRICTIONS Maximum single application rate is 3.0 lbs./A (1.5 lbs. metallic copper equivalent)
Maximum annual application rate is 40.0 lbs./A (20.0 lbs. metallic copper equivalent)
ALMONDS
DISEASE Application Rate (lbs of product/Acre) Minimum Days Retreatment Interval COMMENTS Dormant and–Late Dormant–to Pink Bud Season:
Bacterial Blast (Pseudomonas)

7 Use at dormant to early pink bud. For blast control in sprinkler irrigated orchards or where disease is severe, apply 2–4 sprays at 1.0–3.0 lbs. per acre at 2 week post-bloom intervals or just before sprinkling. Slight leaf injury may occur from post-bloom spray Bloom/Growing Season:
Coryneum Blight Blossom Brown Rot
3.0
5 Use during the early bloom stage (popcorn). A second application in late dormant before foliage buds swell may be necessary when frequent rainfall occurs. To avoid plant injury, do not use after full bloom.
RESTRICTIONS Maximum single dormant application rate is 8.0 lbs./A (4.0 lbs. metallic copper equivalent)
Maximum single bloom/growing application rate is 3.0 lbs./A (1.5 lbs. metallic copper equivalent)

7 Apply first spray at early pre-bloom when catkins are partially expanded. Make three additional applications during bloom and early nutlet stages at 7 to 10 day intervals. 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.
NOTE: Adequate control may not be obtained when copper tolerant species of Xanthamonas bacteria are present.
