What are the pest and disease control methods for peach trees? Explained in one article
What are the pest and disease control methods for peach trees? When should which pests and diseases be controlled on peach trees? We ask experienced netizens to help explain. Peach trees are easy to grow, but their resistance to pests and diseases is weak, and they are most susceptible to damage from aphids, red spider mites, longhorn beetles, and are also prone to brown spot disease, leaf curl disease, gummosis of the trunk, etc. Therefore, Zhongdiwang has compiled...
What are the pest and disease control methods for peach trees? When should which pests and diseases be controlled on peach trees? We ask experienced netizens to help explainPeach trees are easy to grow, but their resistance to pests and diseases is weak, and they are most susceptible to damage from aphids, red spider mites, longhorn beetles, and are also prone to brown spot disease, leaf curl disease, gummosis of the trunk, etc. Therefore, Zhongdiwang has compiled the pests and diseases that need to be controlled during each growth period of peach trees, and listed them in detail below for netizens' reference.
I. Pest and disease control methods for peach trees during the dormant period from December to March:
The main work during the dormant period of peach trees is clearing the orchard, eliminating overwintering pests and diseases, and reducing pest and disease damage in the coming year. Prune off cankered branches, diseased branches, and mummified fruit from the trees, and clear dead branches, fallen leaves, weeds, diseased fruit, and diseased branches from the ground. Scrape off rotten cankers and old peeling bark on branches and trunks, and apply disinfectant fungicide for protection.
Spray the entire orchard once with lime sulfur mixture. Mainly targeting rot disease, brown rot, and scale insects.
II. Pest and disease control methods for peach trees from bud break to before flowering, March to April:
During the stage from bud break to before flowering, the main targets for control are peach shot hole disease, leaf curl disease, and aphids. You can spray with 25% deltamethrin 500x solution + fungicide, which gives good results.
In order to prevent pest and disease damage from weakening tree vigor and cutting off nutrient supply, spray "Guaguo Zhuangdiling" + 0.3% urea + 0.3% monopotassium phosphate before flowering, at the young fruit stage, and at the fruit swelling stage, to protect flowers and fruit and increase the fruit-setting rate.
III. Pest and disease control methods for peach trees during the new shoot growth period from April to May:
During the new shoot growth period of peach trees, promptly pick off damaged new shoots, burn them in a centralized manner, and eliminate pear fruit borer larvae. During this time, the main targets for control are peach brown rot, shot hole disease, anthracnose, aphids, pear fruit borer, leaf roller, leaf miner, and red spider mite.
You can spray with 72% agricultural streptomycin 3000x plus 0.5% abamectin 3000x for control.
IV. Pest and disease control methods for peach trees during the young fruit growth and development period from May to June:
The young fruit growth and development period of peach trees is the first-generation adult stage of the pear fruit borer and the overwintering-generation adult stage of the apple leaf roller, so timely control is key. You can use 40% Fuxing 8000x plus 20% Chongmante 1200x plus boron-calcium treasure 1200x for control.
V. Pest and disease control methods for early-maturing peach varieties during the ripening period from June to July:
The ripening period of early-maturing peach varieties is the second-generation adult stage of the pear fruit borer, and the hatched larvae begin to damage the fruit, making it a key focus for pesticide spraying. In addition, brown rot, shot hole disease, scab, red spider mite, peach fruit moth, leaf miner, aphids, and scale insects also cause damage to peach trees.
For control, you can spray with 70% thiophanate-methyl 1200x plus 20% abamectin 8000x.
VI. Pest and disease control methods for mid-maturing peach varieties during the ripening period from July to August:
The ripening period of mid-maturing peach varieties is also the third-generation adult stage of the pear fruit borer and the first-generation adult stage of the apple leaf roller, and timely control is needed to avoid damage to fruit quality. It is also the occurrence period of brown rot, shot hole disease, anthracnose, cotton bollworm, peach fruit moth, and red spider mite.
For control measures, you can spray with 70% mancozeb 600x plus 5% hexaflumuron 2000x, or 3% abamectin 700x plus 90% methomyl powder 3000x to control pests and diseases.
VII. Pest and disease control methods for late-maturing peach varieties during the ripening period from August to October:
During the ripening period of late-maturing peach varieties, the main targets for control are brown rot, anthracnose, leaf miner, pear fruit borer, peach fruit moth, leafhopper, cicada, and other pests and diseases.
You can spray with 70% thiophanate-methyl 1200x plus 22% Lisha 1200x for control.
VIII. Pest and disease control methods for peach trees from after harvest to the dormant period, October to December:
After harvest, the main targets for control on peach trees are shot hole disease and gummosis. You can spray lime sulfur mixture to disinfect the entire orchard and control shot hole disease. For peach tree gummosis, scrape off the gum stains and apply disinfectant fungicide to eradicate the gummosis.
