Abstract:

To clarify the current control status and existing problems of mango diseases and insect pests control in Guangxi and provide some basic data for the green prevention and control, a series of data were collected and analyzed by the network voting, questionnaire investigation and field survey. Family farms are dominated in Guangxi, accountted for 70.83%. The mango varieties mainly include ‘Tainong’, ‘GUI 7’, ‘Jinhuang’, ‘Renong 1’, ‘Guifei’, ‘GUI 10’ and ‘Jin xing’. 71.58% of mango orchards have two or more varieties. Generally, the occurrence of mango diseases is more serious than those of insect pests in Guangxi. Colletotrichum gloeosporioides and Xanthomonas campestris are the most serious diseases. Chemical control is the most favorite method against the mango diseases and insect pests. 98.95% of farmers adopt the practice of mixing two or more kinds of pesticides when application, 55.32% of farmers choose 2 to 3 kinds of pesticides to mix. The pesticide selection is different. 44.34% farmers rely on their own experience or neighbors, 36.79% rely on the recommendation of pesticide stores, and 18.87% rely on the guidance by agricultural technicians. The input cost of pesticides ranges from 200 to 1000 yuan/667 m 2, but there is no positive correlation between the input cost and mango yield.
