Knowledge of applying pesticides during the rainy season

The following points should be noted when applying pesticides during the rainy season: Pay attention to the use of pesticides with strong absorbability. Such as dimethoate, omethoate, monocrotophos, methamidophos, phosphoamine, insecticidal glycosides, leaf dry spirit, rice bran, carbendazim, dimethazine, thiophanate, triadicotin, beta-aluminum, methofuran Anthracycline, tricyclazole, and fluconazole, etc. These pesticides can be rapidly transferred to various parts of the plant after being absorbed by the stems and leaves of crops, and their efficacy is less affected by rainfall. 1605, methyl 1605, trichlorfon, anti-indolyl, quinoxaline, diflubenzuron, kaffoldin, green copper lactone, and dexamethasone pesticides, although there is no internal absorption, but has a strong surface in the crop The penetrating power and anti-erosion ability are therefore also suitable for application in the rainy season. According to reports, when Ye Lingling is applied to crops for 2 hours, it can produce a systemic uptake effect; Phosphamidans can quickly enter the plants after application, and about 50% of the dose enters the plant tissues within 1 hour after spraying; In the second half hour after the spraying of tricyclazole, one hour after spraying, there was no effect on the efficacy. Pay attention to the quick-acting pesticides that have strong knocking power. Such as phoxim, dichlorvos, omethoate, anti-inhibitory, fast-killing, mixed aldicarb, methomyl, Guangkewei, neocarbide, boling-bao, de-lingling, Xinguang 1 and pyrethroid pesticides After such pesticides are applied, they can quickly exert their prevention and control of diseases and insect pests, so as to avoid or reduce the leaching of rainwater to pharmaceuticals. According to statistics, aphids on crops can be killed within a few minutes after mashing or application, and rice pests can be controlled with mixed carbendazim. After a few minutes of application, most pests fall into the water. Note that the adhesive is added to the drug. In order to enhance the adhesion of pesticides on the stems and leaves of crops, improve the control effect. Soy flour, polyvinyl alcohol, hide glue, etc. are all commonly used adhesives.
