What methods are there for preventing and controlling pests and diseases in mango trees? Please provide an introduction to the methods.
The following methods can be referenced for preventing and controlling pests and diseases in mango trees:
1. Agricultural control
Select improved varieties that are resistant or tolerant to pests and diseases according to local conditions. A single variety should be planted in the same plot, avoiding mixed planting of varieties with different maturity periods. During orchard establishment and cultivation management, measures such as planting windbreak belts, nectar source plants, intercropping between rows or growing grass can be used to create an ecosystem that is favorable for fruit tree growth and natural enemy survival but unfavorable for pest and disease development, maintaining biodiversity and ecological balance.
Through pruning during the mango shoot-flushing stage, flowering stage, fruiting stage and after harvest, remove crossing branches, overly dense branches and diseased or pest-infested branches, and burn them in a centralized manner to reduce sources of infection. Thoroughly clean the orchard in winter, gather dead branches and diseased or pest-infested branches and burn them in a centralized manner to reduce sources of infection. Strengthen cultivation management to improve plant disease resistance, release shoots at the appropriate time, promote neat flushing of each shoot, avoid peak pest periods, and remove scattered young shoots to facilitate unified pesticide spraying. Carry out intertillage, turn the soil and expose it to the sun to kill underground pests.
2. Physical and mechanical control
Use insect-attracting lamps to trap and kill pests active at night, and use yellow fluorescent lamps to drive away fruit-piercing moths.
Use manual methods or tools to capture and kill pests such as scarab beetles and their pupae.
Use colors to trap and kill pests, such as yellow boards, blue boards and white boards.
Use insect-proof nets and insect-catching nets to isolate and capture pests.
Use fruit bagging technology to prevent and control pests and diseases.
3. Biological control
Plant nectar source plants around the orchard and between rows to create an ecological environment favorable for the reproduction of natural enemies. Use mechanical and manual weeding as much as possible, which both controls weeds and protects natural enemies. Collect, introduce, breed and release major natural enemies of pests, such as predatory mites. Use biological pesticides such as fungi, bacteria and viruses, biochemical preparations and insect growth regulators, mainly including Bacillus thuringiensis emulsion, Bacillus thuringiensis powder, biological compound insecticides, abamectin, liuyangmycin, diflubenzuron, chlorfluazuron, flufenoxuron, polyoxin, mifumian, and agricultural antibiotic 120.
