Season is the peak period of diseases, pests and weeds of various agricultural and forestry and horticultural crops. It is also the peak season for applying pesticides. The general requirements for the use of pesticides in summer are: safety (including safety for pesticide application personnel, crop safety, and environmental safety), economical, and effective. Production should pay attention to the following questions:
1. Buy safe pesticides. When purchasing pesticides, they must go to a reputable formal agricultural resource shop to buy them, and do “four don’t buyâ€, that is, there is no pesticide label or incomplete label, “three licenses†on the label (pesticide registration certificate, product standard) No., production license) Incomplete identification, unsatisfied appearance quality, and non-buy beyond product quality assurance period.
2. Reasonable use of pesticides. When there is much rain in summer, when choosing pesticides, one should pay attention to the use of pesticides with strong absorption. Such as dimethoate, omethoate, monocrotophos, methamidophos, phosphoamine, insecticidal glycosides, leaf dry spirit, rice bran, carbendazim, dimethazine, thiophanate, triadicotin, beta-aluminum, methofuran Anthracycline, tricyclazole, fluconazole, etc. These pesticides can be rapidly transferred to various parts of the plant after being absorbed by the stems and leaves of crops. Their efficacy is less affected by rainfall; 1605, methyl 1605, trichlorfon, and antibiotics Although pesticides such as Converse, Quetion, Diflubenzuron, Praderyl Chloride, Green Copper Cumate, and Dyson Ammonia do not have a systemic absorption function, they have a strong penetration and anti-erosion ability on the surface of crops, and are therefore suitable. Apply during the rainy season. According to reports, when Ye Lingling is applied to crops for 2 hours, it can produce a systemic uptake effect; Phosphamidans can quickly enter the interior of the plant after application, and about 50% of the dose enters the plant tissue 1 hour after application; green copper spray In the second half hour after the spraying of tricyclazole, one hour after spraying, there was no effect on the efficacy. Second, we must pay attention to fast-acting pesticides with strong knockdown. Such as phoxim, dichlorvos, omethoate, anti-inhibitory, fast-killing, mixed aldicarb, methomyl, Guangkewei, neovicarb, cotton boll, deliling, Xinguang 1 and pyrethroid pesticides Wait. After the application of such pesticides, they can quickly exert their prevention and control of diseases and insect pests, so as to avoid or reduce the leaching of rainwater to pharmaceuticals. According to statistics, aphids on crops can be killed within a few minutes after the application of anti-Swimmer, and rice pests are controlled with mixed methavironals. Most pests fall to the water within minutes of application.
3. Correct application of pesticides. When pesticides are applied, six precautions must be taken: 1 Dealing with the right medicine. There are many types of pesticides and their characteristics are different. The most suitable pesticide should be selected for the target of prevention and control. 2 timely medication. If the protective bactericide must be used before or at the beginning of the disease, the herbicide should be used before the crop sprouts. 3 amount of medication. The use of pesticides must be used strictly in accordance with the recommended dosage, and any increase or decrease can easily cause damage to crops or affect control efficiency. 4 evenly applied. The pesticide should be applied evenly, and it should not be re-sprayed or missed. This ensures crop safety and is effective against diseases, weeds and weeds. 5 rational mix. 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. 6 safe application. Dispensing and spraying should prevent pesticides from contaminating the skin. It is prohibited to spray high-toxic pesticides at high temperatures during the summer noon. Do not apply pesticides continuously for too long. At the operation site, it is necessary to keep good liquids, poison valleys, and poisonous species to prevent poisoning of humans and animals. Virulent and highly toxic pesticides are prohibited from being used on crops such as melons and fruit trees.
4. Deal with problems in time. For pesticides with poor control effect or large area of ​​phytotoxicity, pesticides should be promptly sent to the pesticide testing organizations for inspection. If they are substandard or shoddy products, they should promptly go to the industrial and commercial, consumer association, quality and technical supervision and other related departments; When the pesticide is improperly applied, it should be promptly taken remedial measures; pesticide personnel poisoning appears in the application and they are sent to a regular hospital for emergency treatment.
