Forest fruit seedlings winter pest control
After the fall, the weather gradually became cooler and the trees stopped growing and entered dormancy, and the pests and diseases entered the wintering period. At this point, due to the maturity of the branches, the resistance of the trees is higher, and the overwintering sites of the pests are relatively fixed, and the resistance is weak, which facilitates the central elimination. Therefore, grasping the favorable opportunity for the dormancy period of trees, combined with tending and management, and eliminating pests and diseases, can reduce the number of pests and diseases and reduce the harm in the coming year. The main control measures for pests and diseases in the dormant period of trees are as follows. Clear litter After deciduous trees, the branches, leaves, weeds, etc. of the pests should be promptly buried or burned in a concentrated manner, which will help reduce the number of pathogens and pests that pass through the winter. Cultivated woodland Before the soil is frozen, the cultivated woodland can not only protect the soil by loose soil, accumulate rain and snow, and promote the growth of roots, but also can turn the remaining litter into the soil. At the same time, it can turn over the winter pests to the ground and be the natural enemy. Prey or freeze to death. Treat the bark In the early winter or early spring, scraping off the old warp skin, diseased skin, insect skin, etc. at the trunk, branch and branch branches, and burning them centrally or deeply, can effectively eliminate pests that overwinter in the rough skin. The depth of the skin scraping is preferably yellowish-green on the skin. Apply 40% methine WP 50 to 100 times liquid soap or 5 to 10 bymide lime sulfur to protect the wound. White trunk After defoliating trees, whitening with a whitening agent at the bases of trunks and branches can eliminate pests and diseases that overwinter on the trunks, and prevent sunburn, freezing injury and hare gnawing. Whitening agent can be used 25 parts of water, lime 10 parts, 1 part of lime sulfur, 1 part of salt and a small amount of animal oil formulated, but also in the whitening agent by adding an appropriate amount of fungicide and insecticide to increase the effect. Spray control After deciduous trees and before germination, they sprayed 5 Baume degrees of lime sulfur and 200 times of sodium pentachlorophenol to eliminate overwintering pathogenic bacteria and eggs and reduce the harm of pests and diseases in the following year.
