ABSTRACT
Greengram is nutritionally the most important legume crop and excellent source of high quality protein (25%). It is consumed as whole grains as well as dal in variety of ways in homes. The leaf blight of greengram incited by Macrophomina phaseolina (Tassi.) Goid. was observed at Agronomy Farm, College of Agriculture, Dapoli. In vitro evaluation of plant extracts revealed that the bulb extracts of garlic (Allium sativum) was most effective in inhibiting the growth of the test fungus followed by ginger and onion. Trichoderma harzianum was the most promising antagonist against Macrophomina phaseolina among the different fungal antagonists tested, followed by Trichoderma viride and Gliocladium virens.
Key words :
Antagonists, greengram, plant extracts, Vigna radiata.
