The pesticide fertilizer is a novel ecological compound fertilizer formed by mixing pesticide and fertilizer according to a certain proportion formula and stabilizing the fertilizer and the pesticide in a specific compound system through a certain process. The pesticide fertilizer is compatible with the pesticide function and the fertilizer function, two field operations of fertilizer application and pesticide spraying are combined into a whole, the pesticide fertilizer has important functions on solving the shortage of rural labor force in China and the rigid requirement of agricultural scale operation, reducing the using amount of pesticide and fertilizer, saving labor force, time and energy, reducing production cost, reducing the pollution of pesticide and fertilizer to the environment, effectively improving crop yield and the like, is a new direction for sustainable development of modern agriculture, is fully recognized in the industry today when water, fertilizer and pesticide integration is vigorously pushed, and becomes an industry focus of attention.
At present, more than 30 medical fertilizer products are registered (some are primary and secondary bags); the registered pesticide fertilizers contain many bactericides and herbicides and are mainly used for preventing and controlling annual weeds, damping off and bacterial wilt in transplanted paddy fields, but the registered pesticide fertilizers contain few products. The biological pesticide fertilizer has the advantages of pesticide fertilizer, conforms to the new trend and new requirements of current environment friendliness and development of low-carbon modern agriculture, is a future pesticide fertilizer development direction, and has wide market prospect. Therefore, in recent years, agricultural researchers at home and abroad attach great importance to the research and application of biological pesticide fertilizers, and develop a plurality of production processes of insecticidal biological pesticide fertilizers and have related technical patents.
