What are the application techniques for peach trees before and after flowering?

1. When the flower buds of peach trees swell, sulfur mixture should be sprayed reasonably, which can not only promote the differentiation of flower buds, but also control pests and diseases.

2. Before peach blossom, fertilization and spraying should be combined. Dilute cypermethrin, imidacloprid, carbendazim, active calcium, antifreeze and silicone appropriately. Then spray it on the peach trees reasonably. Proper application of phosphorus, potassium fertilizer and boron fertilizer at flowering stage is not only beneficial to flower bud differentiation, but also beneficial to later growth.

3. Peach trees should be sprayed with chemicals such as pymetrozine, cypermethrin, amino acids, zineb, active calcium, active potassium and siloxane. Once every half a month, spray continuously for 2-3 times, which has better insect control effect.

When peach trees begin to bear fruit from April to August, cypermethrin, fenpropathrin, avermectin, siloxane, zineb, poison maid and other drugs should be applied to them at this time.

5. Comments: The choice of pesticides is different in different growth stages of peach trees during planting. The key time points of applying pesticide to peach trees are often flower bud expansion period, before flowering, full flowering period, after flowering and June-August every year. The choice of pesticides is best judged according to the actual growth of peach trees. The choice of pesticides is not fixed, so everyone can master it flexibly.
