The main diseases of peach trees in greenhouse are scab, perforation and gummy disease, and the main pests are aphids, leaf mites and leaf moths. For the prevention and control of peach diseases and insect pests in greenhouse, we should give priority to prevention, based on the control of dormant season, and reduce the source of infection. Pre-flowering and post-flowering are the key periods of prevention and control, let alone be taken lightly.

In the dormant season, the orchards were strictly cleaned after winter pruning, and the dead branches and fallen leaves were burned or buried deeply; spray 9281 times and 1000 times of agricultural insects before heating up; spray 65% pentachlorophenol sodium 250 times or 3-5 Baomedu stone sulfur mixture about a week after heating (scale cracking period).

About a week before the growing season (bell flower time), spray 1000 times of liquid carbendan plus 2000 times of liquid to kill Surel or 2000 times of liquid to clean at one time; if aphids are serious during the flowering period, you can smoke the shed with aphid control agent, and the smoke time in the shed is generally no more than 6 hours. one week after flowering, 1000 times of chlorothalonil or 1000 times of methyl topiramate plus 4000 times of azithromycin can be sprayed throughout the garden. After setting the fruit, 50% carbendazim, 1000 times methyl thiophanate and 72% carbendazim 1000 times can be sprayed alternately at intervals of 2-3 weeks. In order to cure both diseases and pests, insecticide and acaricide can be added when fungicides are sprayed. When leaf miner occurs after fruit picking, 1500-fold solution of thiazuron 3 can be added. At the same time, it can also be interspersed with zinc sulfate lime solution of 3.5 and 240 zinc sulfate, which can effectively control various diseases and insect pests.
