In daily production activities, farmers often use pesticides because of the non-standard operation, which causes the efficacy of the drug to decline, and even causes phytotoxicity, which endangers the safety of humans and animals, and causes losses in production. Therefore, Xiaobian reminds farmers to pay attention to the following points: Aluminum Door Handle On Aluminum Plate Wenzhou Shenghong Metal Products Co.,Ltd , https://www.shenghonglock.com
Strictly arranging pesticides that are counterfeit, polluted, and prohibited by the state cannot be used. Pots, wood, glass or plastic products should be used for containers and utensils for pesticides. Metal utensils should not be used to avoid chemical reactions, reduce drug efficacy and even produce poison. When dispensing it is preferably used a secondary dilution method, i.e., by diluting the original drug with a small amount of water, stir, and add water to the desired concentration, stirring with addition of water, so to maintain a uniform solution concentration, so as not to affect the control effect. In order to enhance the efficacy of the drug, the appropriate amount of vinegar can be added before the pesticide is poured or the pesticide synergist is added; in order to increase the adhesion of the pesticide, the pesticide manufacturer recommends to add 3000 times 6501 spreading agent or 0.1% washing powder. Adding a small amount of alcohol to the control of cockroach pests can enhance the efficacy and reduce the resistance.
It is generally advisable to choose spray medicine for sunny afternoons to avoid application of drugs when the air humidity is high, fog is heavy, and dew is applied for a long time. Spraying is required to be meticulous and thoughtful, requiring the mist to be fine and uniform, so that the liquid does not drip from the blade. When the cockroach pests are controlled, the back of the leaves must be sprayed, and the mites should pay attention to the dense parts of the worms.
According to the information on the pest report issued by the local plant protection department, the safe drug is sprayed during the growth period in which the pests and diseases are most sensitive to pesticides. When applying chemical pesticides, be sure to pay attention to the protection of natural enemies. Try to choose pesticides that are less harmful to natural enemies, and pay attention to avoid the reproductive breeding period of natural enemies. Pesticides should be used interchangeably. It is not possible to use one pesticide to continuously control the same pests and diseases to avoid drug resistance. When mixing, strictly follow the pesticide mixing table operation, and pay attention to the use with the mixture. It is necessary to spray less and not spray pesticides with long residual period. Do not spray or spray a broad-spectrum insecticide in the early stage of crop growth. The control period of pests should be selected when the number of pests reaches the control index, the period of the pest's vitality is weakest, the pests are concealed, the crop resistance is strong, and the peak of natural enemies is avoided. When using the drug, the dosage, concentration and safety interval of the pesticide should be strictly controlled. In the effective concentration range, the low-concentration agent should be used as far as possible to control the pests and diseases.
Skillfully use pesticide 1, local spray. When the local crops are seriously damaged, targeted spraying can be adopted, which not only controls the occurrence of pests, but also reduces the amount of pesticides used, reduces the production cost, and more importantly, protects the natural enemy insects.
2. Spray on the ground. Spreading or spraying pesticides on the ground can both kill pests and reduce damage to natural enemy insects.
3. Selective medication. The use of a special killing agent can not only protect the natural enemy, but also protect the natural enemy.
4. Use microbial preparations to control pests. Such as Beauveria bassiana preparations to control cockroach pests.
5, cleverly mixed pesticides. The mixed use of pesticides with different action mechanisms can not only delay the production of crop resistance, but also enhance the efficacy, reduce the dosage and reduce the cost. For example, the combination of a delayed-type dichlorfen and a fast-acting pyrethroid pesticide can speed up the knockdown of the drug against the pest, reduce the killing of natural enemies, and reduce the amount of pyrethroid pesticides.
6. Comprehensive prevention and treatment. Combine chemical control with agricultural control and biological measures, and implement comprehensive prevention and control, so as to minimize or reduce the use of pesticides, reduce the amount of drugs used and the number of drugs used, protect the safety of natural enemies, and ensure the normal growth and development of crops.
The medication is skillful and safe medication is the key. The majority of farmers and friends follow the above points when using drugs to avoid the occurrence of safety accidents.
