Choose a sunny day and high temperature medication. Because the pests in the winter when the temperature is high, the feeding and breathing intensity is greater than the cold weather, the liquid is sprayed onto the worm body, and the drugs are brought to the body more, which is beneficial to play the poisoning effect. Appropriate increase in dosage. In the winter, if the dosage is applied according to the conventional dosage, the pests often cannot die after taking the medicine, so it is necessary to increase the dosage appropriately. The specific temperature should be determined according to the temperature, but generally does not exceed 50% of the regular dose. When applying pesticides in winter, water should be added strictly according to the dilution factor. The amount of water should not be increased or decreased at will. Reasonable selection of pesticides suitable for winter application. In general, stomach poisons and contact agents are less affected by temperature, and systemic and fumigants are more affected by temperature. Such as enemy killing, dichlorvos, dimethoate, methamidophos and other pesticides, low temperature will significantly affect its insecticidal effect; and deltamethrin, phoxim, stone sulfur mixture and other pesticides can still play at lower temperatures Better insecticidal effect. In addition, the herbicide is applied in winter, and the effect of displaying the effect is much longer than that in the hot season. After the drug is used, it is necessary to wait patiently, as long as the drug solution is sprayed into place, generally no need to re-spray.
Priority is given to the use of soil pesticides. The price of soil pesticides is low, and the disadvantage is that it is easy to cause phytotoxicity. However, the fruit trees have strong resistance to pesticides during the dormant period in winter, and it is economical and effective to control pests with pesticides such as Bordeaux mixture and stone sulfur mixture. Pay attention to extending the safety interval of pesticides. When pesticides are applied in winter, the degradation rate of pesticides becomes slower, and the residual period of pesticides in crops is relatively prolonged. When controlling pests and diseases of vegetable crops in winter, special attention should be paid to prolonging the safety interval of pesticides to ensure human health.
