There are tricks to apply pesticides during the rainy season
First, the use of systemic pesticides Systemic pesticides can enter the plant body through the roots, stems, leaves and other parts of the crop, and transport to other parts, play a role in a certain period of time. Such as carbofuran, monocrotophos, omethoate, phosphonium and other insecticides and carbendazim, triadimefon, thiophanate, rifampicin, fast keratin, carbazole, Ye Lubao and other fungicides, such pesticides Four to five hours after application, more than 80% of the active ingredients are absorbed into the tissues by the crops, and they do not lose their efficacy due to the rain. Second, the use of quick-acting pesticides such as dichlorvos, monocrotophos, methamidophos, fast extinguishers, enemy kills, and quick killings in pesticides falls into this category. These pesticides have a strong contact and smoke killing effect and are rapidly poisoned, killing the pests 1-2 hours after application. Third, the use of rain-resistant pesticides such as bactericides such as jinggangmycin and extermination and rapid gram-lining, etc. have good resistance to rain, after application of 1-2 hours or 4-5 hours, even if it does not affect the shower Efficacy. Fourth, adding an adhesive agent to the liquid can increase the adhesion of the pesticide to the surface of the crop and the body surface of the pest. Formulate the pesticide solution, add 50 grams of liquid detergent per 50 kilograms of liquid agent, such as 50-75 grams of detergent, and spray it in a timely manner after stirring evenly, which has a good synergistic effect. Fifth, to improve the application methods such as the choice of systemic insecticide before the occurrence of a large area of ​​pests, mix fine soil applied to the soil in the crop root zone, let the plants absorb, so that the insects feed poisoning and die. This method of applying the root zone avoids rain flushing and is particularly suitable for use during the rainy season. Six, clever selection of application time According to the pest activity law clever selection of application time. For some pests that come out at night, such as rice leaf roller, it was chosen to apply pesticides in the evening so that the pesticides could be absorbed by the plants. The insects would die after being poisoned within 2-3 hours.
