(1) Anthracnose of mango: After flower buds germinate to one month before harvest, spray 70% thiophanate-methyl 700 times every 15 days, or 25% Sulfocarb 300 times once;
(2) Mangosaurus lateralis: 1 clean up the dead branches, scrape the rough skin, and reduce the places of phlegm; 2 When the young shoots or flower axis is 2-3 cm long, spray 20% of the liquid to kill 6,000 times, or 2.5%. The enemy killed 4000 times fluid for 2-3 consecutive times.
(3) Mango assemblages: In the young fruit stage, 40% dimethoate emulsion and 90% crystal trichlorfon are sprayed in each 1000 times solution, once every 10 days, and sprayed 2-3 times.
