Pay attention in the control of diseases and insect pests of kiwi fruit under high temperature in summer
In the high temperature season in summer, fresh kiwi fruit is in the young fruit stage, which is the early stage of all kinds of diseases and pests, and also the key period of chemical control. The safe use of pesticides is the need to improve the quality of agricultural products and avoid the occurrence of drug harm. Therefore, we should pay attention to the following points in the control of kiwi fruit diseases and pests
1.High efficiency, low toxicity, low residue and environmental friendly pesticides and biological agents are preferred, and the use of high toxicity and high residue pesticides is prohibited, so as to avoid causing drug harm, excessive pesticide residues, ecological environment pollution, human and animal poisoning, etc.
2.Pay attention to reasonable mixing. The results showed that the leaf area of kiwi fruit was large and it was sensitive to chemical pesticides, so it should be prepared and applied in strict accordance with the recommended dosage on the pesticide label; Second dilution method should be used to prepare granules and wettable powder; In order to avoid harmfulness, it is necessary to mix several kinds of medicament and micro fertilizer, and do not increase the concentration at will.
3.Check whether the performance of the applicator is good before application to avoid "running, emitting, dripping and leaking"; Attention should be paid to alternate drug use to prevent and control diseases and insect pests and produce drug resistance.
4.Avoid spraying in high temperature period (12:00-4:00 p.m.), wear protective clothing, protective cover, etc. when spraying, and do a good job in whole body protection, so as to avoid poisoning.
5.The used pesticide bottles and bags should be taken out of the field for centralized treatment. It is strictly forbidden to throw them in the field, causing environmental pollution.
6.High temperature season is a mixed period of kiwi fruit diseases, such as brown spot and physiological leaf blight. Therefore, water and fertilizer management should be strengthened to improve kiwi fruit disease resistance and stress resistance.
7.It is strictly prohibited to increase the concentration of the drug without authorization, so as to cause drug harm
