Abstract: | Soaking faba beans or treating their soil with the bio-agents Abamectin (a fermentation product from Streptomyces avermitilis), a strain of Bacillus thuringiensis, Nemaless (containing strains of Serratia marcescens), and Sincocin-AG were compared to the nematicide Oxamyl and significantly (P 0.01 and/or P 0.05) reduced the population density of M. incognita with increasing the measured plant growth . On this basis, seed soaking was recommended as an economical, easy and pollution free method for managing M. incognita. |
