1. The grass to fight pests. After the fruit is harvested, it can be trapped in the trunk of the Sorghum ring or branches to attract insects. This method can trap overwintering pests into grass and wintering in grass rings. After entering the winter, the grass handle and the grass ring are removed and burned to kill a large number of pests.
2. Clearing the Garden. Remove weeds first, and destroy wintering sites such as maggots and planthoppers. The defoliation, repression, smashing, and stacking of fruit tree defoliation, corn stalks, and glutinous rice can be used to kill more than 98% of corn borers, leaf roller moths, and bridge insects and cabbage caterpillars that live in them.
3. Deeply exterminate insects. The underground pests such as borers, navicular caterpillars, flat moths, and cockroaches can be turned to the ground and frozen to death through arable land; the ground can also destroy the nests of cotton bollworms, armyworms, wheat leaf beetles, locusts, etc. and prevent their emergence. Or hatching, it is better to do it in the late autumn and early winter. Pests are buried in the ground between 10 and 15 centimeters over winter, so the soil should be deeply turned 20 to 30 centimeters before the soil is frozen or in early spring and the pests are “sleptâ€. The adults or cockroaches are exposed to the ground and frozen to death. Poultry and bird feeding; this also allows loose soil, conducive to the maturity of the soil and enhance soil permeability. It is more ideal to deepen the ploughing of frozen water within 7 days.
4. Scrape off the insects. A variety of overwintering pests are hidden in the rough skin, cracks, and cracks. The bark must be scraped off with a knife. Special attention should be paid to scraping the branches. The time is from the beginning of December to the next February. The barks of apples, peaches, plums, apricots, and citrus are thin and should be lightly scraped and lightly shaved to see the yellow-green skin as the degree; pears and jujube are thicker and can be scraped and scraped to see the red cortex. it is good. After scraping the skin, lime sulfur can be used to disinfect or brush the white coating agent on the wound surface to ensure the effect of scraping off the skin. Scraped diseases and bark of insects should be completely buried or burned out of the park.
5 white pest control. The white-coated tree trunk is a protective measure for wintering of fruit trees. It can fill cracks, eliminate bacteria, and reduce the incidence of pests and diseases in the coming year. White reflection can reduce the temperature difference between winter and spring, prevent sunburn, and enhance the frost resistance of trees. Whitening agent formulation and preparation method: 30 parts of quicklime, 2 parts of clay, 2 parts of lime sulfur stock solution, 36 to 40 parts of water, 1 to 2 parts of salt, and appropriate amount of insecticide. Lime and salt are first dissolved in water and poured into lime sulfur mixture and clay. Mix well and serve. The amount of coating does not flow down. Apply once after defoliation to before freezing and before sprouting in early spring. The main part of the painting is the backbone and the base of the main branch. The tree branches of large trees should also be painted, but they should not be applied to the buds.
6. Trim and exterminate insects. The residual branches and diseased shoots on the fruit trees are all hidden with many germs and pests. They should be thoroughly removed in conjunction with the winter pruning of fruit trees, and the branches should be burned outside the park.
7. Frozen pest control. That is, the low-temperature treatment will open all the doors and windows of the grain storehouse, so that the temperature will fall below -5°C and be frozen for a long time, which will prevent the reproduction of pests and freeze-kill the pests.
8. Fumigation and pest control. The granules and cotton silos were sprayed with 5% dichlorvos emulsion for 20 to 25 times, and sealed for 4 to 5 days. The control effect of the moth and rice elephant was over 90%.
9. spotted pest control. By using 40% omethoate, 50% monocrotophos, or 50% methamidophos 200 times, the crowns, branches, and buds of fruit trees can be applied to prevent overwintering aphids.
10. Insect extermination in winter. In the case of night freezing, winter irrigation in winter fields, wheat fields, and orchards can kill the eggs of the roots and the larvae of the brown planthoppers, and reduce the emergence of earthworms due to the decrease of oxygen content in the soil and sudden temperature drop. rate. Repeated alternation between freezing and elimination can improve soil structure and facilitate the growth of crops.
11. Spray insecticide. In the fields of weeds, such as wheat fields and orchards, sprayed with 2.5% deltamethrin and 20% quick killing diced 4000-5000 times can kill a large number of locusts, fleas and fleas; The fruit tree spray 1 to 2 times 3 to 4 Baume degrees of lime sulfur can effectively control pear garden locust, red spider, etc.; with 40% omethoate 1500 to 2000 times liquid spray, can effectively prevent the occurrence of blind ticks, etc. .
12. Block holes and eliminate insects. The rotted hole of the fruit tree is the “base camp†for the wintering of pathogens and pests. It can be inserted into the cave to stir, and the insects hidden in the holes and holes can be stabbed to death, and then the mud can be closed tightly with mud to make all the pests suffocate and die.
From the winter to the early part of the winter, it is a time when crop pests are lurking in a suitable environment for winter dormancy, and it is also a favorable period for eliminating pests. At this point, disinsecting can minimize the base number of overwintering pests and diseases, and it can get twice the result with half the effort.
