Studies on the Interaction Between Meloidogyne incognita and Rhizoctonia solani on Soybean

In nematode inoculated prior and after fungus treatment resulted in only slight to moderate inhibition of galling, nodulation and female development. Simultaneous inoculation of fungus with nematode exhibited, on linear decrease in final population of nematode in soybean. Subsequent soybean grain weight as well as growth parameters were suppressed by simultaneous, sequential and fungus inoculation but more damage were assessed during simultaneous inoculation than other treatments. Physiological studies also showed the significant alterations in chlorophyll a and b, protein, oil and nitrate reductase enzyme of soybean.
