Prevention and control of main pests and diseases of mango

The main diseases at the flowering stage include powdery mildew, anthracnose, and tobacco mold. The main pests include the nightworm, the locust, the hummer, the venomous moth, the locust, and the chafer.

In the aspect of pest control, when the flowering of the flower is about 3 cm, trichlorfon, dichlorvos and omethoate can be used to control the night moth, aphid and thrips; the key application of cypermethrin, dimethoate, dichlorvos, etc. from the initial flowering stage to the Xiehua period Aphids, thrips, poisonous moths, and scorpions, etc.; in the Xiehua period, sprayed fruit-preserving fertilizer and foliar fertilizer can be combined with pest control to improve fruit setting and promote young fruit to turn green. The use of pesticides should be rotated, pest and disease prevention should be combined, and disease prevention and pesticide mixing should be considered as much as possible to reduce the number of spraying.

When the flower spike is about 3 cm, it can be sprayed once with methyl thiophanate and carbendazim to prevent the infection of anthracnose at the flowering stage. Powdery mildew should be prevented during the initial flowering period, and it can be sprayed 2-3 times with the disease or powder rust, pesticide The application interval is 7-10 days. Spring shoots should be removed in time. When the spikes are too long and too much, consider removing some of the spikes or short-cutting the spikes. It can prevent rain and water, save tree nutrients, increase fruit set rate, and cultivate. Should be followed by strong flowers, sitting fruit fertilizer. From the flowering period to the second physiological fruit drop period, the anthracnose and rot disease should be prevented from infecting small fruits, and the fungicides such as methyl thiophanate, chlorothalonil and mancozeb can be sprayed to prevent disease and fruit.
