Reasonable crop rotation and intercropping can not only control insect pests, but also make full use of soil fertility. It can also be deeply ploughed, which not only promotes the growth and development of plant roots, but also increases the plant’s resistance to disease and destroys pest nests in the soil. Remove weeds from the field during planting and clean up after harvesting to reduce the chance of pests in the coming year.
First, pest control
1. Reasonable rotation and intercropping can be carried out, which can not only prevent and control insect pests, but also make full use of soil fertility. The length of rotation time can be determined according to the survival time of pests in the soil.
2. Deep tillage can not only promote the growth and development of plant roots, but also enhance the resistance to disease of plants, and destroy dormant pest nests in the soil, which can directly eliminate pests. When planting can be tilled and dried several times, which is conducive to improving soil physical properties.
3, in the process of planting to remove weeds in the field in a timely manner, medicinal plants after harvesting, need to weed clean the field, and combined with pruning the disease and insect residues and dead leaves, burn with fire or deep buried, so as to reduce the incidence of the second year of insect pests.
4, most of the insect pests are closely related to the planting of medicinal plants at a certain developmental stage of phenology, if you can make the growth and development stage miss the dangerous period of pest proliferation, so that you can avoid the insect pests, but also can achieve the purpose of pest control.
Two, what kind of pests emamectin salt control
1, Megamectin salt can prevent and control red and yellow spiders, cotton bollworm, aphids, flies, green insects and other pests, Megamectin salt full name amamectin benzoate, the agent is white or light yellow crystalline powder, soluble in acetone and methanol, slightly soluble in water. Emamectin is a new type of highly efficient semi-synthetic antibiotic insecticide synthesized from the fermentation product abamectin B1.
2. The larva and many other pests of Lepidoptera have extremely high activity, which has both gastric toxicity and palpation effect. The agent is widely used in the control of various pests on vegetables, fruit trees, cotton and other crops.
3. The agent does no harm to beneficial insects in the process of pest control, which is conducive to the comprehensive control of pests, but also expands the insecticidal spectrum and reduces the toxicity to humans and animals.
4. Megamylate has the characteristics of high efficiency, broad spectrum, safety and long residual duration. It is an excellent insecticidal and acaricidal agent, and has high activity against lepidopteran pests, mites, coleoptera and homoptera pests such as cotton reelworm, and it is not easy to cause resistance to pests.
