The present invention relates to an environmentally-friendly composition for controlling root-knot nematode. The composition for controlling root-knot nematode shows excellent effects of controlling root-knot nematode by using soybean and fly ash. A mixing ratio of the soybean and the fly ash is 7:3. The composition for controlling root-knot nematode manufactured to be mixed at such ratio supplies nutrition of the soybean and various inorganic components of the fly ash to roots of a plant, thereby protecting the plant from root-knot nematode.COPYRIGHT KIPO 2015본 발명은 친환경 뿌리혹선충 방제용 조성물에 관한 것으로, 본 발명의 뿌리혹선충 방제용 조성물은 콩과 플라이애쉬를 이용하여 우수한 뿌리혹선충 방제효과를 발휘한다.
