What pesticides should pay attention to in summer

1. Safely apply pesticides and disable highly toxic pesticides. Pharmaceuticals and pesticides should be applied to prevent pesticides from corroding the skin. It is prohibited to spray pesticides at high temperatures during the summer noon. The continuous application time should not be too long. Keep the liquid at the spraying site to prevent poisoning of humans and animals. In particular, biological pesticides, ultraviolet rays in the sun have a killing effect on spores, direct light irradiation for 30 minutes, spores can be about 50% of death, irradiation for 1 hour, the mortality rate of up to 80%. Therefore, the application of biological pesticides can be applied after 4 pm, cloudy days without moderate to heavy rain, and can be applied throughout the day. The

2, strictly control the amount of application. Any pesticide should be used in accordance with the recommended dosage. Any increase or decrease can easily cause crop damage or influence. The

3, timely medication, medication time is right, control effect is ideal. Such as protective fungicides must be used before the onset or early onset of the disease, herbicides to the correct application of sub-dosage type, such as pre-emergence application and stem and leaf treatment. The

4, spraying time, sunny 7-9 am, the best time for spraying is 4-6 pm.

5, rational mix of pesticides. After mixing, the toxicity to humans and animals cannot be increased, chemical changes between active ingredients cannot occur, and the cost of medication cannot be increased. The

6, the application should be uniform and can not be re-spray or missed spray to ensure the safety of crops, effective against diseases and weeds. The

7, the right medicine. There are many varieties of pesticides and their characteristics are different. The most suitable pesticides should be selected for the control subjects.

In addition, if the drug efficacy is poor or phytotoxicity occurs, the drug should be promptly sent to the pesticide testing unit for testing, and timely remediation should be carried out in the event of injury. The first is the remediation of fertilization, which produces phytotoxicity on the foliar, such as spots of medicine, foliar coking, or yellowing of the leaves, and is usually remedied by foliar dressing. Second, herbicides that inhibit or interfere with the growth of plants can be sprayed. To alleviate.
