How to eliminate pests on fruit trees in autumn and winter? Master these four steps
The "four-part suite" for eliminating pests on fruit trees in autumn and winter
(Agricultural Wealth Network) Late autumn is the period when pest and disease activity in orchards declines, and it is the peak period for pests and diseases to seek out habitats to lay eggs and reproduce. It is also the best time to eliminate fruit tree pests and diseases. Therefore, eliminating pests and diseases after the autumn fruit harvest is a top priority and must not be taken lightly.
1. Pruning, clearing away remaining branches and fallen leaves In autumn and winter, in conjunction with pruning, cut off dead branches, diseased branches, diseased shoot tips, and pest-infested shoot tips, and clear away weeds and fallen branches and leaves in the orchard and its surroundings, gathering them for burning, which can eliminate a large number of overwintering pests. After pruning, promptly apply the oil-based "wound healing and anti-corrosion film" to the wounds to seal them and protect the wounds for healthy healing.
2. Plowing and turning the orchard soil
Plowing and turning the orchard soil is both an important measure for improving the soil and promoting increased fruit tree yields, and an effective method for eliminating overwintering pests and diseases. Through plowing and turning, pests and pathogens in the deep soil layers can be turned up to the surface to be frozen to death, dried to death, or pecked by natural enemies, while pests and diseases buried deep underground cannot emerge from the soil and are smothered to death, thereby reducing the overwintering population base.
3. Trapping and killing pests
Taking advantage of pests' selectivity for overwintering sites, after autumn, bind grass bundles or pieces of burlap sacks to the large branches of fruit trees to attract pests to pupate and overwinter, then kill them all at once. According to surveys, this method can achieve a trapping effect of 47%-78% on the smaller apple fruit moth and the smaller pear fruit moth, and also has a good trapping effect on the hawthorn red spider mite, the jujube leaf roller, the swirling leafminer moth, the apple small leaf roller, the brown leaf roller, and others, especially when the overwintering pest population density is relatively high in that year, its trapping effect is even more pronounced.
4. Chemical control
During the leaf-drop dormancy period of fruit trees, scrape off disease spots, raised rotten bark, and diseased bark, and apply "Tree Protector General" so that the diseased bark dries up and falls off quickly. Then spray "Tree Protector General" throughout the orchard to sterilize and disinfect, protecting the tree for safe overwintering.
The harm caused by fruit tree pests and diseases seriously affects fruit yield and quality. Eliminating fruit tree pests in autumn can achieve twice the result with half the effort, so disease and pest control work must be done well in the hope of a bumper harvest next year.
