Spray the fruit after pruning
In general, after pruning the fruit tree, 5 Baumite Lithosulfide plus 200 times of sodium pentachlorophenol are sprayed on the tree body, requiring the tree and the ground to be sprayed. This will not only protect the wound and branches, but also Elimination of fleas, scale insects, rot, rotenakia, and pear scab, which are overwintering in the trunk and soil, has better control effects. The spray must be meticulous and thoughtful, especially the trunk and branches of the branch must be sprayed, requiring a spray-type spray on the fruit trees. For dry earthworm pests, such as Tianniu, can be artificially killed or dilute with contact-type pesticides into effective concentrations to perforate the hole, and then use the yellow mud to seal the hole, so that the insects hiding in the trunk can be poisoned.
