One or three masters 1. Master the law of spawning and pay attention to the site of application. The cotton bollworm lays eggs and is prolific on the top of the cotton plant, on the young leaves of the fruit branches, on the buds and on the leaves. Therefore, the focus of application should be on the top of the cotton plant and on the tender tips, buds and stalks of the fruit branches.
2. Grasp the law of hatching and pay attention to timely prevention and treatment. For cotton bollworms, it is necessary to strengthen the report and grasp the peak of spawning and the law of hatching. The hatching rule is that the egg head is white, two days yellow, three days black, and hatching in four days. Two days after hatching, the growth point was harmed, and the four-day migration harmed the young bud. The appropriate period of prevention and treatment should be better after the peak of hatching, before most of the eggs become black or hatched.
3. Master the law of feeding and pay attention to the time of application. It has been observed that cotton bollworms are active for feeding after 8-11 and after 15:00, and rarely active during the high temperature period at 12-13. Therefore, the application time should be better at the active feeding time. Do not apply at high temperature. When applied at high temperature, it is easy to be decomposed and decomposed. Not only the operator is easily poisoned, but also the drug is poor. In the morning, there is dew application, the concentration of the liquid is easy to dilute, the adhesion is poor, and the efficacy is not good.
Second, three notes 1. Pay attention to the alternating use of pesticides, and several pesticides should be used alternately. Do not use a pesticide continuously to prevent the cotton bollworm from becoming resistant to the drug.
2. Pay attention to pesticide compounding. Pesticide compounding can improve the efficacy and delay the resistance of cotton bollworm to drugs. When pesticides are compounded, it should be noted that acidic and alkaline pesticides cannot be compounded.
3. Pay attention to the concentration of pesticides. The concentration of pesticides can not be increased or decreased arbitrarily, and must be matched according to the instructions for use of pesticides. Increasing the concentration of cotton plants is susceptible to phytotoxicity, and reducing the dosage will reduce the efficacy.
Third, increase the amount of liquid medicine, cotton plants evenly. The amount of liquid medicine is very close to the effect of controlling insects. The amount of liquid medicine used is small, and the effect of spraying cotton plants on uneven insects is poor. When controlling the second generation of cotton bollworm, 40-50 kg of liquid per acre is used; third and fourth generations of cotton bollworm, 80-100 kg of liquid per acre. All the cotton plants are evenly treated and the effect is good.
Improving the efficacy of cotton bollworm control is an effective way to reduce investment and reduce costs. Three key points should be grasped.
