Synergism between pesticide and fertilizer in controlling root-knot nematode was investigated by field randomized block test. The results showed that the best control efficiency was shared by 0.5% abamectin and 25% mixed pesticide (abamectin and carbosulfan), 24.1% and 28.0%, respectively. The positive effect was found by synergism between pesticide and fertiUzer in controlling reot-knot nematode. The economic benefit and agricultural benefit were gained by controlling root-knot nematodes. The results suggested that the agricultural and ecological benefit could be gained through the integration of agricultural practice and chemical technology in controlling root-knot nematode. 展开更多
