In daily production activities, farmer friends often use pesticides that are not standardized, resulting in a decline in efficacy, and even causing phytotoxicity, endangering the safety of people and livestock, and causing losses to production. Therefore, farmers are reminded to use drugs to pay attention to the following points:
Strictly dispose of pesticides that are not allowed to use counterfeit goods, pollute the environment, and are prohibited by the government. Containers and utensils used to dispose of pesticides should use pottery, wood, glass or plastic products. Never use metal utensils to avoid chemical reactions, reduce the efficacy or even produce poisons. It is best to use the secondary dilution method when dispensing, that is, dilute the original drug with a small amount of water, stir well, and then add water to the required concentration, add water while stirring, so that the concentration of the drug solution remains uniform, so as not to affect the control effect. In order to enhance the efficacy of the drug, it is advisable to add the appropriate amount of vinegar before pouring the pesticide or use the pesticide synergist at the time of dispensing; it is recommended to add 3000 times 6501 spreader or 0.1% detergent powder to increase the adhesion of pesticides. Adding a small amount of alcohol in the prevention of pests can enhance the efficacy and reduce the drug resistance.
The standard spray spraying should generally be selected in the afternoon of sunny days, to avoid spraying when the air is high in humidity, heavy fog and dew, so as to avoid phytotoxicity. Spraying for meticulous and thoughtful, requiring fine and uniform fog point, the liquid does not drop from the leaves for the degree. The back of the leaves must be sprayed when controlling the pests. The locusts should pay attention to the dense parts of the insects.
Pesticides are sprayed on when the pests and diseases are most sensitive to pesticides. When using chemical pesticides, we must pay attention to the protection of natural enemies. We must try to choose pesticides that are less harmful to natural enemies, and pay attention to avoiding the breeding period of natural enemies. Pesticides must be used alternately. It is not possible to use a single pesticide to continuously control the same pest and disease so as to avoid drug resistance. When mixing, strictly follow the pesticide mixing and use table, and pay attention to mix and use. Spray less, do not spray pesticides with a long residual effect. Crops are not sprayed or sprayed with broad-spectrum insecticides in the early stages of crop growth. The pest control period should be selected when the number of pests reaches the prevention and control index, the weakest period of pest vitality, the hidden danger of pests, the strong phase of crop resistance, and the avoidance of natural enemies. When pesticides are used, the dose, concentration, and safety interval of pesticides should be strictly controlled. In the range of effective concentrations, pests and insects should be controlled with low concentrations of pesticides.
Clever use of pesticides
1, local spray. When the local crops are seriously damaged, targeted spraying may be adopted, which not only controls the occurrence of pests, but also reduces the use of pesticides, reduces production costs, and more importantly, protects natural enemies.
2, the ground spray. Spreading or spraying pesticides on the ground can kill pests and reduce damage to natural enemies.
3, selective medication. The use of agents with special killing effect can not only play a good control effect, but also protect natural enemies.
4, the use of microbial agents to control pests. For example, Beauveria bassiana preparations prevent and control acarid pests.
5, clever mix of pesticides. The mixed use of pesticides with different mechanisms of action not only delays the development of crop resistance, but also enhances efficacy, reduces the amount of pesticides used, and reduces costs. For example, the combination of slow-acting diflubenzuron and a quick-acting pyrethroid pesticide can speed up the rate of drug knockdown, reduce the number of natural enemies, and reduce the amount of pyrethroid pesticides.
6, comprehensive prevention and treatment. Combine chemical prevention with agricultural prevention and control and biological measures, implement integrated prevention and control, so as to minimize or minimize the use of pesticides, reduce the amount of medication and the number of medications, protect the safety of natural enemies, and ensure the normal growth and development of crops.
Medication is tricky and safe medication is the key. The majority of farmer friends follow the above points when using drugs to avoid safety accidents.
