The rainy season is often the season in which crops, diseases, pests and diseases such as various field crops, fruit trees, and vegetables occur. In order to ensure the control effect of pesticides on pests and weeds, the following points should be noted when applying pesticides during the rainy season:
Selects pesticides with strong absorbability
Such as dimethoate, omethoate, Ye Ling Ling, rice bran, carbendazim, thiophanates, triadimefon, B-aluminum, trimethoprim, tricyclazole, fluconazole, etc., such pesticides absorbed through the crop stems and leaves Afterwards, it can be quickly transmitted to various parts of the plant, and its efficacy is less affected by rainfall.
Choose knockout pesticides
Such as phoxim, dichlorvos, omethoate, anti-influx, and pyrethroid pesticides. After the application of such pesticides, 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.
Rain-resistant pesticides
Trichlorfon, anti-indoles, quinoline, diflubenzuron, kaffoldin, green copper, daisam, jinggangmycin and other pesticides have strong penetration and anti-erosion ability on the crop surface. Apply during the rainy season.
Choose to apply without rain
When applying pesticides, it is necessary to pay attention to the selection of no rain period; if it rains within 24 hours after application, it is necessary to re-spray once, and spray concentration should be appropriately reduced when re-spraying.
Add adhesives to the liquid
The addition of adhesives can enhance the adhesion of pesticides on the stems and leaves of crops and improve the control effect; soy flour, polyvinyl alcohol, and hide glue are all commonly used adhesives.
