Department of Agriculture hardiness zones 5 through 9, are susceptible to a wide array of problems, such as pest infestations and fungal diseases. Implementing a spray program will help manage diseases and pests that can harm the peach tree and reduce its fruit production.
Dormant Stage The dormant stage typically occurs during the colder months when the tree has no leaves and the buds have yet to break. Dormant horticultural oil applied in the winter dormant season will control San Jose scale, while fixed copper sprays applied in the dormant stage controls peach leaf curl. Dormant oil also smothers other unwanted pests, such as aphids, mites and adidas running shoes thrips, that may be overwintering on the peach tree.
Pink Bud Stage When the flower buds are pink, expanding and preparing to open, adidas philippines office address the peach tree is in the pink bud stage. Insecticide sprays applied during this stage will control aphids, thrips and mites. However, don't spray the peach tree with insecticides during the pink bud stage if horticultural oil was applied during the dormant stage. Dormant oil won't control Oriental fruit moth or twig borers, so apply the bacterium insecticide Bacillius thuriengensis to the peach tree during this stage.
Spring Bloom Once the buds have opened and the peach blossoms fill the branches, the spring bloom season has arrived. Fungicides, such as chlorothalonil, lime sulfur, thiophanate methyl and captan, applied during spring bloom will help prevent brown rot. A second and third application of the fungicide may be required if there is an abundance of rain. During the spring bloom stage, apply a fertilizer high in nitrogen to the peach trees once a month throughout the spring and summer bloom period. Follow the application rate recommended by the fertilizer manufacturer.
Petal Fall to Shuck Split Petal fall is when the petals fall freely from the tree. When all petals have fallen, the peach tree is in the shuck stage. When the fruit begins to grow and splits the flower shuck, the peach tree has entered the shuck split stage. Treat the peach tree with pesticides, such as Imidan, during this stage to control scabs and stink bugs. After petal fall but before shuck split, insecticide application may be needed every 7 to 10 days, according to the University of Florida.
Pre Harvest Pre harvest occurs when the fruit has grown but still hasn't ripened. Insecticides containing permethrin or carbaryl applied to the trunk and soil surrounding the base of the tree will control peach tree borers. Treatment for peach tree borers should be done early in the pre harvest stage to allow for the recommended PHI (pre harvest interval) as stated on the insecticides label. Insects infesting peach trees during the pre harvest stage increase the possibility of brown rot, so apply sevin or permethrin if needed. Always follow the PHI recommended by the manufacturer.
Post Harvest Post harvest stage is after the fruit has been harvested but the tree is not yet in the dormant period. After harvest or in early August, whichever is later, use a trunk spray containing endosulfan to control peach tree borers.
