Use the higher rates on hard to thin <br />varieties at the early timing which is the <br />80% petal fall to 6 mm fruit size. Use the <br />lower rates on easy to thin varieties and at <br />the later thinning period which is the 10 <br />to 16 mm fruit size. The rate to use per <br />acre will depend on varieties, tree size, row <br />spacing, weather conditions at the time of <br />and following applications. Consult with <br />the local fruit thinning experts in your area <br />for the proper rate to use under your <br />conditions. <br />The optimum spray gallonage will depend <br />on the tree size, planting density, row <br />spacing and amount of foliage. Use suffi- <br />cient spray volume to insure adequate <br />coverage (100 to 400 gallons/acre). Avoid <br />spray to the point of runoff. Reduce spray <br />coverage to the lower portion of the tree <br />since overthinning may occur here. <br />Factors such as climatic temperature, high <br />humidity, frost, tree age, variety, nutrition, <br />previous crop, pruning and bloom may <br />influence fruit thinning results with the <br />product. Exercise caution to avoid possible <br />overthinning. For the most effective <br />results, apply under good drying condi - <br />tions and when daytime temperatures (OF) <br />will be 70 to low 80's for the following one <br />to three days. Application with daytime <br />temperatures in excess of BOO F may result <br />in overthinning. <br />
