Good effect of pesticides in the rainy season

The rainy season is often the most common season for various field crops, fruit trees, vegetables and other pests and diseases. In order to ensure the control effect of pesticides on pests and weeds, the following points should be noted when applying pesticides in the rainy season:

Select systemic pesticides such as dimethoate, omethoate, leaf dry spirit, rice bran, carbendazim, thiophanate, triadimefon, ethylphosphorus aluminum, nail cream, tricyclazole, and fluconazole, etc. After being absorbed by crop stems and leaves, the pesticides can be quickly transmitted to various parts of the plant, and their effects are less affected by rainfall.

Select pesticides with strong knockdown properties such as phoxim, dichlorvos, omethoate, anti-carbophos and pyrethroid pesticides. After the application of such pesticides, the prevention and control of pests and diseases can be quickly exerted, thereby avoiding or reducing the leaching of the medicament by rainwater.

Pesticides such as trichlorfon, anti-carbophos, quetiapine, chlorfenapyr, fluclette, green lactate, dexamethasone and jinggangmycin, which are resistant to rain, have strong penetrability on the surface of crops. And anti-scour ability, suitable for application in the rainy season.

When it is rain-free, it is rainy in summer. When applying pesticides, it is necessary to pay attention to the choice of no rain. If it rains within 24 hours after application, it should be re-sprayed once, and the spray concentration should be appropriately reduced when re-spraying.

Adding an adhesive to the drug solution and adding the adhesive can enhance the adhesion of the pesticide on the stems and leaves of the crop and improve the control effect. Soy flour, polyvinyl alcohol, leather glue, etc. are commonly used adhesives.
