1. Timely application The management of the mouth of each field is different, and the growth conditions of the same crop are different. Therefore, according to the actual situation of the insect case report combined with Honda, the time of application of the drug should be applied at the right time. Both advance and push will not pay off. For example, rice aphids must be used at the peak of their incubation, and the effect is best.
2. Alternate use of the same pest, the use of different varieties, and the same effect of pesticides alternately sprayed, can overcome the resistance of insect pests, and achieve good control results. For example, aphids and spider mites can be used alternately with urinary washing agents, chlorpyrifos, chlorpyrifos, and phoxim.
3. Mixed spray treatment Sometimes crop pests and diseases can occur several kinds at the same time. In order to achieve the purpose of concurrent treatment, one or two kinds of pesticides for controlling pests and diseases can be scientifically selected for use with the mixture, so as to achieve the control effect of "one arrow and two sculptures".
4. Some of the crops and fruit tree pests have different aggregation points. If they are treated equally, the effect is not good. The plants with serious pests can be selected and directly smeared with a brush. This method has special effects on red spiders and beetles on cotton, vegetables and citrus.
5. Application to the mouth Any kind of pests and diseases have their symbiotic laws, should choose the right pesticides and the best prevention time, timely and comprehensive poisoning and prevention.
6. Treating a single drug and treating a wide range of low-toxic, high-efficiency, and low-residue pesticides can cure multiple pests and diseases. For example, organophosphorus pesticides have special effects on insect pests such as red bollworm, aphids, thrips, and planthoppers. Once these kinds of pests occur, they can be treated with one spray.
