Peach Disease Prevention and Control in Early Spring
In March and April, as temperatures gradually rise, bacteria and pests begin to become active. Therefore, the prevention and control of pests and diseases in peach trees will play an important role in reducing the incidence of diseases and insect pests throughout the year. Because the peach flowering period is particularly sensitive to pesticides, spraying pesticides is prone to phytotoxicity, so it must be used before or after flowering. Peach rot disease is the peak period of peach rot disease in spring. After the disease is found, it should be wiped in time and wiped again after half a month. However, it should be noted that prevention and treatment of the disease can not cure the lesions, otherwise it is easy to cause fluidic disease. Pharmacy can be used: 5% bacteriostatic water solution 30 ~ 50 times liquid, or 4% agricultural anti-120 water agent 50 times, or rust will clear 2 ~ 3 times liquid. Aphids and small green leafhoppers in the middle and late March of March are the hatching period of overwintering peach aphids, the wintering of North Korea balls and overwintering nymphs and small green leafhoppers. Agents can be used: 10% imidacloprid wettable powder 4000 ~ 5000 times, or 3% Mobilan EC 2000 ~ 2500 times, or 50% anti-inferiority WP 2000 times. If the single treatment of small green leafhopper can be used 25% fluconazole WP 1000 to 1500 times, and can cure both North Korea ball scorpion, mulberry white wolfberry and so on. Fungi, a large class of chlorophyll - free, can not carry out photosynthesis, heterotrophic lower class of plants. These include bacteria, slime molds and fungi. Their common characteristics are: the plant body has no differentiation of roots, stems and leaves, does not contain chlorophyll and other photosynthetic pigments (except a few photosynthetic bacteria), can not carry out photosynthesis, saprophytic life or parasitic life, that is, heterotrophic life. Most of the reproductive organs are single-cell structures, and the zygotes do not develop into embryos.

Peach leaf thinning occurs early in the year when it is cold and rainy. It can start spraying for the first time when flower buds bloom red. Agents can be used: 2 to 4 Baume degrees lime sulfur, or equal amount of Bordeaux mixture 100 times, or 50% carbendazim, 70% thiophanate-methyl WP 800 to 1000 times. And timely removal of diseased leaves, concentrated burning lesions to reduce the source of bacteria.
Peach brown rot disease can occur from flowering to fruit maturation, if the flowering period and the fruit maturation period are more severe in the case of rain and fog. Can be sprayed before and after the flowering time of 50% fast-king or 50% benomyl WP 1500 times, can also be 10-15 days after flowering combined with peach scab disease spray control.
