Abstract
Field experiments were conducted in 2011 and repeated in 2012 to study the nematicidal potentials of acacia, brassica, neem, and seaweed as alternatives to chemical nematicide on population management of Heterodera glycines and growth and yield of soybean. Results obtained showed acacia at 200 g, neem at 450 g, brassica at 1000 g, and seaweed at 2000 g caused the maximum suppression of population of H. glycines and produced the highest yield and growth of soybean. Neem, brassica, acacia, and seaweed caused reduction in H. glycines population by 48.3%, 41.4%, 34.5%, and 28.3%, respectively. Also, neem, brassica, acacia, and seaweed produced increase in soybean pods number by 58.7%, 33.7%, 28%, and seaweed 37.9%, respectively. The results obtained showed the potentialities of these plant materials as alternative to synthetic chemical pesticides. The plant could be utilized in a sustainable farming system to save the environment, conserve the biodiversity, and protect man against harmful effects of chemical nematicides.
