The study of pesticide-fertilizer combination prepared with biochar and chlorantraniliprole and its effectiveness in controlling fall armyworms

In this research, a pesticide-fertilizer combination (PFC) was fabricated using chlorantraniliprole and biochar. The PFC had a spherical shape, smooth surface, uniform particles, relatively dense structure and good compression resistance. The adsorption propertie of biochar to chlorantraniliprole was investigated. During the preparation of pelleted granules, the types and concentrations of core fillers and adhesives were screened and optimized. Besides, the safety to maize and effectiveness against fall armyworms of PFC had been investigated. Meanwhile, The PFC could promoted growth of maize significantly and control fall armyworm effectively. This work provides a promising approach to slow the release of chlorantraniliprole, which has a potential application to enhance the pesticides efficiency.
