Description
Technical Field
The invention belongs to the field of agricultural chemicals, and relates to a slow-release bactericidal insecticide and application thereof.
Background
The rice is the first large grain crop in China, the perennial planting area is 3000 hectares, the rice occupies 33 percent of the cultivated land area, and the yield occupies 45 percent of the total grain yield in China. In the rice cultivation process, the generation of plant diseases and insect pests seriously restricts the yield and the quality of rice. The rice blast has wide area, rapid prevalence and large loss, and is the most important disease for rice paddy fields. The use of chemical agents is an important measure and an effective means for preventing and treating rice diseases and insect pests, but the conventional agents and prevention and treatment methods have the disadvantages of more pesticide application times and high pesticide application cost; and a large amount of medicament can be sprayed into water, so that water body pollution is caused.
Therefore, the search for a product which is efficient, economical, convenient to apply, labor-saving and labor-saving is a new direction for developing new products of pesticides at present.
Due to land circulation and rural labor force transfer, agricultural scattered manual labor is replaced by forms of specialized organizations, cooperative society and the like, and agricultural pest control faces to the specialized, intensive and high-efficiency integrated control mode. The rice seedling culture is also developed from one family to industrialized and specialized seedling culture. According to survey, the industrial seedling raising in 3 provinces of northeast China reaches more than 60-70%. Through industrialized seedling raising, the manual labor that the quality of seedlings is reduced and the price is increased day by day is provided.
The cultivation of strong seedlings or the prevention and control of diseases in production fields through seedbed pesticide application is the greatest requirement for rice farmers, and the fertilizer is applied to the early rice seedling bed, so that the use is convenient, and the time and the labor are saved. If the plant diseases and insect pests in the rice production field can be controlled by the treatment of the medicament on the seedbed, the effect of achieving twice the result with half the effort can be achieved. And the quantity of pesticide sprayed to farmlands is greatly reduced, and the ecological environment is protected.
Although there are many benefits to controlling pests in rice production fields through seedbed application, this technique is very slow to implement. The reason for this is that the rice has a growing period of 100-120 days from transplanting to harvesting, and the duration of the general agent is usually only a few weeks. Therefore, the selection of the agent and the control of the rate of release of the agent are critical to success.
Disclosure of Invention
