Utilization of plant materials for control of soybean cysts nematode

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.

Characterization of Heterodera sojae Virulence Phenotypes in Korea

“…Eggs are protected from heat, drying, chemicals, and other adverse environmental conditions by the protective cysts that are formed by eventual hardening and tanning of the cuticle of females (Epps, 1958;Grainger, 1964). The use of resistant varieties and non-host crops in rotation has proven to be a more effective and sustainable method of managing H. glycines than other control practices (Acharya et al, 2016;Auwal et al, 2014).…”
