What kind of medicine is used to control rice borers?

In the field of rice field control, aphids (heartworms) can be used according to the occurrence of pests in the field, and can be used in the period from the hatching period to the younger larvae. It can also combine the control of sheath blight, rice smut, rice blast, etc. during the key growth period of rice. Comprehensive prevention and treatment of diseases and rational use of drugs. Timely and sufficient use of avermectin, emamectin benzoate, indoxacarb, chlorantraniliprole, tetrachlorfenamide, ethyl spinosyn, cyanofluorfen, etc., usually Good control effect can be selected according to local conditions. Indoxacarb and ethyl spinosad also have good control effect on older larvae. These large-sized worms can be preferentially used in combination with avermectin and emamectin benzoate. Agent control.

Chloramphenicol benzamide and tetrachloremamide have strong systemic conductivity, which is conducive to the protection of new leaves, and has a long-lasting effect. It is a low-grade lepidoptera such as Euphorbia, Chilo suppressalis, Sanhuai, and Rice leaf roller. Pests have high activity, and they can usually achieve ideal control effects when they are applied regularly or combined with appropriate overall control. These two drugs have a unique mechanism of action, mainly stomach poisoning, and contact killing, mainly to activate the pest ryanodine receptor, excessive release of calcium ions stored in smooth muscle and striated muscle cells, causing the muscles of the pests to weaken and eventually die. . It is also possible to apply the medicine in the larval stage of the mites to the 1st to 2nd instar larvae, so as to make full use of the advantages of good internal sorption. For example, the “Kangkuan Early Use” program promoted by the company in the paddy field has a good control effect on the aphid hazard, so that the number of aphids in the field is always maintained at a low level, and the rice is grown while effectively controlling the aphids. better. Among them, the “Kangkuan No.1” program advanced the use period of Kangkang 200g/L chlorantraniliprole suspension on live rice to the early stage of tillering, and the use period on transplanted rice was early to before transplanting. The use of the "give medicine" is used to control the mites harm effectively over a long period of time.
