Spraying time of rice insecticides
Do not spray insecticides on rainy days, this is the basic knowledge of farmers, but many farmers often spray at noon on sunny days, which is very undesirable and harmful, because: 1, at noon, the light is strong, pests hide in the back of leaves and stems, the insecticidal effect is poor; 2, drugs volatilize and decompose late under high temperature and strong light, and the control effect is poor; 3, drugs do great harm to the human body. At this time, pesticide poisoning accidents are most likely to occur. Spraying insecticides is best at 8: 30 am and 4: 30 pm, because the dew is dry at this time in the morning, the medicine will not be diluted by dew and the efficacy will not be reduced, and the temperature is not high. It is the time when the activity of sunrise pests is most vigorous, and the control effect is the best. It is time for nocturnal pests to start their activities when the light is getting weaker in the afternoon. Spraying insecticides can effectively kill nocturnal pests.
