One or three mastery
1. Master the law of spawning and pay attention to the application site. The cotton bollworm lays eggs and is prolific on the top of the cotton plant, on the young leaves of the top of the fruit branches, on the buds and 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. Master 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. The second and third generations of cotton bollworm eggs can be hatched in three 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 rules of feeding and pay attention to the time of application. It has been observed that cotton bollworms are active for feeding after 8-11 hours and after 15:00, and there is little activity 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, high temperature is easy to decompose and apply to the drug, not only the operator is easy to poison, but also the drug effect 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.
Two, three attentions
1. Note that pesticides are used interchangeably, and several pesticides are used alternately in turn. 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 pesticide concentration. 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 dosage of the liquid medicine is very close to the insect control effect, and the amount of the liquid medicine is small, and the effect of spraying the cotton plant on the unevenness of the insect is poor. 40-50 kilograms of liquid per 667 square meters, the cotton plant is uniform in all parts, the effect is good.
