Fertilizer with pesticide is a new type of complex fertilizer with controlling of rice weed. The results of two years field test showed that fertilizer with herbicide has the good effect on controlling grass, sedge and other weed at 35.0 kg/667m2 (effective component of herbicide is 26.0g/667m2). It does no harm to the rice seedling, and fertilizing fertilizer with herbicide has the same yield as general fertilization. This can reduce the production cost , optimize cultivation technique and has a bright future of fertilizer with herbicide.
