Almond, Apricot, Cherry, Plum, Prune

36.36 gals.
(18 lbs.)
Bacterial Blast (Pseudomonas), bacterial canker, blossomcherry brown rot, Coryneum blight (shot hole)51.20 to 64.00
(0.198 to 0.248) on Almond,
all others
60.00 to 90.00 (0.232 to 0.348)
7Make the first application before fall rains and a second at late dormant. Use higher rates when conditions favor the disease. If needed, agricultural-type spray oil may be added. For cherries: Where the 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.
Apple

32.32 gals.
(16 lbs.)
Anthracnose, blossom blight, European canker (Nectria), shoot blast (Pseudomonas)51.2 to 64
(.198 to .248)
N/A (Only one application is permitted per season.)Apply before fall rains. Use higher rates when conditions favor the disease. Note: Using on yellow varieties may cause discoloration. To avoid discoloration, pick before spraying.
Apple scab, fire blight, Phytophthora root rot, verticillium wilt51.2 to 64
(.198 to .248)
N/A (Only one application is permitted per season.)Make an application between the silver tip and the green tip. Apply as a full cover spray for early season disease suppression. Note: Moderate to severe crop injury may occur from a late application. Discontinue use when the green tip reaches 1/2 in.
Apple scab19.2 to 25.6
(.074 to .10)
5Extend spray schedule where fruit finish is not a concern. Continued applications may be made at 5- to 7-day intervals between the 1/2-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 blight19.2 to 25.6
(.074 to .10)
5
Collar rot, crown rot32
(.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 fall after harvest for best results. Do not apply to foliage or fruit. Only one application is needed per year.
Avocado

38.18 gals.
(18.9 lbs.)
Anthracnose, blotch51.2 to 64
(.198 to .248)
14Apply when bloom buds begin to swell and continue the application at bimonthly intervals for 5 to 6 applications. Use higher rates when conditions favor the disease.
Banana

38.17 gals.
(18.9 lbs.)
Sigatoka (black and yellow)19.2
(.074)
7Apply by air in 3 gal. of water. If needed, agricultural-type spray oil may be added. Apply on a 7- to 14-day schedule throughout the wet season. Apply at 21-day intervals during dry periods.
Black pitting32
(.124)
7Mix the product in 100.00 gal. 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.
Cacao

31.81 gals.
(15.75 lbs.)
Black pod19.2 to 64
(.074 to .248)
14Begin applications at the start of the rainy season and continue while infection conditions persist.
Coffee

25.45 gals.
(12.6 lbs.)
Coffee berry disease (Colletotrichum coffeanum)38.4 to 64
(.149 to .248)
14Apply the first spray after flowering and before the onset of long rains, and then at 14- to 28-day intervals until picking. Use higher rates when conditions favor the disease.
Bacterial blight (Pseudomonas syringae)38.4 to 64
(.149 to .248)
14Begin the 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 the disease is just before, during, and after flowering(s), especially when coinciding with wet weather. Use higher rates when rainfall is heavy and disease pressure is high.
Leaf rust (Hemileia vastatrix)19.2 to 32
(.074 to .124)
14Apply before the onset of rain, and then at 14- to 21-day intervals while the rains continue. Use higher rates when rainfall is heavy and disease pressure is high.
Iron
spot (Cercospora coffeicola), pink disease (Corticium almonicolor)
19.2
(.074)
14Use a concentrate or dilute spray. Begin the treatment at the start of the wet season and continue at monthly intervals for 3 applications.
Mango

96.96 gals.
(48 lbs.)
Anthracnose38.4 to 64

7Apply bimonthly after the fruit set until harvest. Use higher rates when rainfall is heavy and disease pressure is high.
Olive

36.36 gasl.
(18 lbs.)
Leaf spot, olive knot, peacock spot52 to 86
(.201 to .333)
30Make the first application before winter rains begin. A second application in early spring should be made if the disease is severe. Apply higher rates for heavy disease pressure or when conditions favor disease development.
Papaya

42.82 gals.
(21.2 lbs.)
Anthracnose26 to 52
(.101 to .201)
7Apply before the disease appears. Repeat at 10- to 14-day intervals under light disease pressure. Shorten spray intervals to 7 days under heavy disease pressure. The addition of a spreader is desirable. Use higher specified rates when the disease is severe.

(.074)
7Apply before fall rains and again during dormancy before spring growth starts.
Fire blight19.2
(.074)
5Apply 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.

12.72 gals.
(6.3 lbs.)
Kernel rot, shuck rot (Phytophthora cactorum), Zonate leaf spot (Cristulariella pyamidalis)19.2 to 32

7Apply the first spray at early pre-bloom prior to or when catkins are partially expanded. Make additional applications during bloom and early nutlet stage, or as needed when frequent rainfall or extended periods of moisture occur. Thorough coverage of catkins, leaves, and nutlets is essential for effective control. Note: Adequate control may not be obtained when copper-tolerant species of Xanthomonas bacteria are present.
