What should be paid attention to for peach trees in summer? Please advise.
In summer, peach trees mainly need attention in the following two areas:
1. Do a good job of summer pruning.
1. Arrange the main and secondary branches well.
2. Remove the branched water sprouts in the inner canopy.
3. Unbranched fruiting branches about 40-50 cm long can be twisted.
4. If the inner canopy is relatively open and there are extended branches, semi-slanting branches can be used for cutting back so as to develop them into branch groups.
2. Pests and diseases
1. Slug moths: pay close attention to the occurrence and control of the first generation of slug moths; use 20% diflubenzuron No. 3 at 1500 times dilution.
2. Red spider mites: use 73% propargite EC at 2000 times dilution.
3. Shot hole disease: after the plum rain begins, peach shot hole disease reaches its peak period. Fruit growers are advised to carry out control at the beginning of the plum rain period and in the middle of the plum rain period (the interval between the two applications is 10-15 days). Use 1:2:200 zinc sulfate lime solution, or 65% zineb at 500 times dilution, or agricultural streptomycin at 3000 times dilution.
4. Red-necked longhorn beetles and peach leafminer moths: strengthen observation of these two pests in late June. For red-necked longhorn beetles, manually capture adults, dig out larvae, and use cotton wadding dipped in 80% dichlorvos at 30 times dilution to plug the bore holes. For peach leafminer moths, use 20% diflubenzuron No. 3 at 1500 times dilution for control.
