Management of Meloidogyne incognita with Pleurotus ostreatus and P. tuberregium in soybean

The effects of single or mixed inculcations of Pleurotus ostreatus and P. tuberregium, fungal species on the spread of plant parasitic nematode Meloidogyne incognita and growth of soybean (Glycine max L. Merrill) cultivars TGX 923-2E, TGX 1440-1E and TGX 1485-1D was studied under glasshouse conditio...

Description
Summary:The effects of single or mixed inculcations of Pleurotus ostreatus and P. tuberregium, fungal species on the spread of plant parasitic nematode Meloidogyne incognita and growth of soybean (Glycine max L. Merrill) cultivars TGX 923-2E, TGX 1440-1E and TGX 1485-1D was studied under glasshouse conditions. Eight treatments including control were tested on the growth, nodulation, yield, galling incidence and development of nematode in soybean. Effects of mixed inoculation with M. incognita + P. ostreatus, M. incognita + P. tuberregium, M. incognita + P. ostreatus + P. tuberregium and including inoculation of only fungi in combination P. ostreatus + P. tuberregium and alone on plant growths and yields were significantly higher than that of only single inoculations of M. incognita. In other words growths on plants with inoculums of either single or mixed of P. ostreatus, or P. tuberregium were similar to control plants. Statistically P. ostreatus in the treatment where it appeared significantly (P less than 0.05) increased nodule weight, which stimulates plant growth characters when compared to P. tuberregium Progressively higher galling incidence and higher number of juvenile population of M. incognita were found in soybean with only single inoculation of M. incognita. Lower plant growth nodulation and yield per plant were also recorded in soybean with only nematode. But the harmful effects of nematodes were partially suppressed by P. tuberregium, while P. ostreatus showed complete control of nematode present in cultivar TGX 1440-1E.
