How to control cotton blindness

The cotton blind insects with the special effects medicine are hemiptera cotton pests, sucking mouthparts, nymphs and adult skins all having a layer of waxy, crawling fast and strong ability to move. We have repeatedly tested the pesticides on the market, Demonstration, the best effect is a combination of phoxim and malathion pesticides. The virulence test results showed that the mortality rate was 100% in two hours; the laboratory test results were 98% in the corrected mortality rate; the field test results and the corrected mortality rate were 95%, both of which were in the top of the pesticides tested. Phoxim is a highly effective and low-toxic pesticide. It has a strong knock-out power against the blind stink bug. However, due to its short residual period, it can easily be revived when used alone. Malathion has three drug effects: stomach poisoning, contact killing, and fumigation. It is a broad-spectrum insecticide. Although its efficacy is long, its knockdown ability is not as good as that of phoxim. The two drugs have the advantage of complementing each other and are therefore the best. Currently on the market, there are 25% octocin, malathion, and 20% benzothiazide produced by the Nori agricultural pesticide plant in Langfang. They are properly formulated, and penetrants and synergists are added. Ideally, if you can't buy it, you can mix it yourself. When cotton bollworms happen at the same time, adding the right amount of acetylated amine phosphorus will have a multiplier effect.

The key period for the first time of prevention and control was in the middle and late May. This is the first time that the disease has been controlled and the prevention and control started when one hundred or two strains have one or two insects. The second critical period of prevention and control was in the middle and early June. In the budding stage, cotton was also the nymph eclosion stage of the second generation of green nymphs. A large number of adult insects transferred cotton fields in succession, and the number of newly-infested strains in the field was as high as 3% to 5%. There are 3 to 5 strains of insects, it is necessary to pay close attention to prevention and treatment, the first and second generations occur relatively relatively neat, as long as the prevention and control in time, it is easier to rule. From the end of June to the third generation of the nymph incubation period, there will be overlapping generations and gradually no obvious algebraic boundaries. In addition, the cotton fields will be closed and enter the period of special difficulties. The top of the main stem and the top of the fruit branches shall be promptly inspected and newly damaged in the field. The strain rate is 5% to 10%, and 100 strains have more than 5 insects. It should be controlled in time. Generally, it is controlled every 7 days until late September.

The rule of general defense is to be thoroughly treated, and there is no such thing as leaving behind the worms. It has the characteristics of strong fertility, protection from light, nightfall, and transfer hazards. Adults have a long life span. They lay eggs 1 to 2 days after emergence. The spawning period lasts 30 to 40 days. Each female adult can lay 37 eggs, and the egg period is generally 6 to 7 days. The hazard period lasts from mid-May. In the first ten days of October, 140 days were required to completely eradicate the blind. In addition to the above two issues, we must implement the principle of unified defense, rule thoroughly, and leave no residue. 1, to carry out household control, to prevent the transfer of hazards; 2, timely removal of weeds in the field, do a good job of prevention and control of the surrounding host, and strengthen the management of cotton fields to prevent overgrowth and reduce the base number of insects. 3, after the prevention and control to be checked, the residual insects should be controlled below the control index, when the amount of insects in the cotton field is large, continuous treatment should be carried out and completely controlled to control the chance that the cotton cocoon continues to multiply in the cotton field.
