| Crop and Maximum Annual Rate of Product in gal. per acre. (lbs. Metallic Copper) | Disease | Rate/A fl. oz. (lb. Cu2+/A) | Minimum Treatment Interval (Days) | Directions |
|---|---|---|---|---|
| Almond, Apricot, Cherry, Plum, Prune 36.36 gals. (18 lbs.) | Blossom brown rot, Coryneum blight (shot hole) | 51.2 to 64 (.198 to .248) on Almond, all others 60 to 90 (.232 to .348) | 5 | Apply during early bloom. Do not apply after full bloom or injury may occur. Use the higher rates when rainfall is heavy and disease pressure is high. |
| Black knot (plum) | 32 to 64 (.124 to .248) | 5 | Make application at bud swell up to early bloom for early disease suppression. Apply before full bloom. Use higher rates when rainfall is heavy and disease pressure is high. Note: To avoid plant injury, do not use after full bloom |
|
| Cherry leaf spot (sour cherries only) | 38.4 to 64 (.149 to .248) | 7 | Apply at petal fall as well as 1 to 2 times after petal fall. Use the lower rates where disease infection is light and use the higher rates for a dormant application or where disease infection is moderate to heavy. Do not apply to sweet cherry or the English Morello variety as severe injury will result. Note: Moderate to severe injury such as leaf spotting and defoliation may occur from post bloom applications. |
|
| Apple scab, fire blight, Phytophthora root rot, verticillium wilt | 51.2 to 64 (.198 to .248) | N/A (Only one application is permitted per season.) | Make one application between silver-tip and green-tip. Apply as a full cover spray for early season disease suppression. Note: Moderate to severe crop injury may occur from late application; discontinue use when green-tip reaches 1/2 inch. |
|
| Apple scab | 19.2 to 25.6 (.074 to .10) | 5 | Extended spray schedule where fruit finish is not a concern. Continued applications may be made at 5 to 7 day intervals between ½ inch green-tip and first cover spray. Note: Moderate to severe crop injury may result from this extended spray schedule. It is not intended for fresh market apples or for apples where fruit finish is a concern as it is likely to cause fruit russeting. |
|
| Fire blight | 19.2 to 25.6 (.074 to .10) | 5 | ||
| Collar rot, crown rot | 32 (.124) | N/A (Only one application is permitted per season.) | Apply as a drench on the lower trunk area of each tree. Apply in early spring or in fall after harvest for best results. Do not apply to foliage or fruit. Only one application per year | |
| Black pitting | 32 (.124) | 7 | Mix product in 100 gallons of water. Apply by spray to the fruit stem and the basal portion of the leaf crown. Apply during the first and second weeks after fruit emergence. | |
| Bacterial blight (Pseudomonas syringae) | 38.4 to 64 (.149 to .248) | 14 | Begin spray program before the onset of long rainy periods and continue throughout the rainy season at 14 to 21 day intervals. The critical time for spraying to control disease is just before, during and after flowering(s), especially when coinciding with wet weather. Use the higher rates when rainfall is heavy and disease pressure is high. | |
| Leaf rust (Hemileia vastatrix) | 19.2 to 32 (.074 to .124) | 14 | Apply before the onset of rain and then at 14 to 21 day intervals while the rains continue. Use the higher rates when rainfall is heavy and disease pressure is high. | |
| Iron spot (Cercospora coffeicola), pink disease (Corticium almonicolor) | 19.2 (.074) | 14 | Use concentrate or dilute spray. Begin treatment at the start of wet season and continue at monthly intervals for three applications. | |
| Eastern filbert blight | 64 to 155 (.248 to .60) | 14 | Apply as a dilute spray in adequate water for thorough coverage. Make applications starting at bud swell to bud break and continue at 14 day intervals or as needed until early May. Thorough coverage is essential. Use the higher specified rates when rainfall is heavy and disease pressure is high. If needed, agricultural type spray oil may be added. | |
| Fire blight | 19.2 (.074) | 5 | Apply at 5 day intervals throughout the bloom period. Note: Russeting may occur in copper sensitive varieties. Excessive dosages may cause fruit russet on any variety. |
|
| ball moss, Spanish moss | 38.4 to 64 (.149 to .248) | 14 | Apply in 100 gallons of water in the spring when ball moss is actively growing, using 1½ gallons of spray per foot of tree height. Make sure to wet ball moss tufts thoroughly. The addition of a non-ionic surfactant will improve control. A second application will be required after 12 months. | |
| Bacterial Blast (Pseudomonas), bacterial canker, Xanthomonas, blossomcherry brown rot, Coryneum | 51.2 to 64 (.198 to .248) on Almond, all others 60 to 90 (.232 to .348) | 7 | Make first application before fall rains and a second at late dormant. Use higher rates when conditions favor disease. If needed, agricultural-type spray oil may be added. For Cherries: Where disease is severe, an additional application shortly after harvest may be required. Note: Foliar injury may occur from post-bloom sprays on almonds, especially on Ne Plus varieties. | |
