Various methods can be adopted to deworm apple trees, including agricultural control, physical control, biological control and chemical control. Here are some specific pest control methods:
Agricultural control:
Reasonable fertilization: Increase the application of base fertilizer, promote the growth of fruit trees, enhance tree growth, and improve the resistance of fruit trees to diseases and pests
.
Reasonable pruning: cut off the branches of diseases and insects, increase light and ventilation, and reduce the occurrence of diseases and pests
.
Turning the tree tray: Turning the pests that overwinter in the soil to the surface of the soil, forcing them to die or be pecked by birds
.
Physical control:
Scrape bark: Eliminate various pests that overwinter on the trunk and remove germs that overwinter on the tree
.
Artificial insect trapping: according to the habits of pests, artificial killing measures are taken to eliminate them
.
Yellow board trapping: Placing yellow boards in orchards to trap winged aphid during migration and flight
.
Biological control:
Use natural enemies: such as the release of pine caterpillar trichogramma and other natural enemies to reduce the number of pests
.
Biological pesticides: Use 0.3% matrine water agent 200 ~ 300 times liquid spray to control the harm of apple yellow aphid and red spider
.
Chemical control:
Rational use of pesticides: scientific use of pesticides according to the regularity of disease and insect occurrence and pharmaceutical characteristics
.
Chemical control: such as the use of 40% fluosilazole cream 300 times plus 3000 times silken cream mixture to smear the rot scar
Or use 20% fenvalerate emulsion 2000-4000 times liquid and so on
.
Fruit bagging: Fruit bagging can reduce the direct damage of pests to the fruit
.
Sex pheromone trapping: Use the sex pheromones of pests to trap and reduce the number of pests
.
Clear garden: apple leaves after cleaning the leaves, remove the sick fruit, scrape the apple rot disease scar, winter pruning after the removal of the residual leaves, and spray a Beaume 3 ~ 5 stone sulfur mixture in time
.
Through the above comprehensive control measures, the pests on the apple tree can be effectively controlled and the healthy growth of the apple tree can be protected.
