Apply a dormant spray of zinc sulfate (36%) at a dilute 

 rate of 20 lbs per 100 gallons; do not concentrate this 

 spray above 2X. Do not apply it within 3 or 4 days of 

 another spray, such as oil. If a dormant spray of zinc 

 sulfate is not applied, use a zinc-containing fungicide 

 in 3 or 4 of the cover sprays. 



Maintain leaf boron levels between 35-50 ppm. This can 

 be accomplished either by soil or foliar applications of 

 boron. Soil applications of boron (B) should be applied 

 to orchards every 3 years. Borax is the common material 

 used. The rates of application per tree vary with age 

 and size. Apply 1/4 lb of fertilizer borate (high-grade 

 - 13.6%) or its equivalent to young trees, 1/2-3/4 lb to 

 medium age and size trees, and 3/4-1 lb to large or mature 

 trees . 



If the soil application of boron is followed by a wet 

 spring and summer, it may be advisable to apply 2 foliar 

 applications of boron the following year.

Apply 3 to 5 calcium nitrate sprays at 10 day intervals 

 starting 2 weeks after petal-fall. We suggest using cal- 

 cium nitrate (fertilizer or technical grade) at the rate 

 of 5 lbs per 100 gallons of water. A spreader or wetting 

 agent, such as Triton B, should be used at the rate of 3 

 fluid ounces per 100 gallons of water.
