RESPONSE OF DIFFERENT MUNG BEAN VARIETIES AGAINST MACROPHOMINA PHASEOLINA (TASSI) GOID AND IN-VITRO STUDIES OF PLANT EXTRACTS AGAINST PATHOGEN

Abstract

Twenty seven varieties/lines of mung bean were tested through artificial inoculation against charcoal rot disease in the field area of Department of Plant Pathology, University of Agriculture, Faisalabad. No variety/line was found immune to charcoal rot disease. Azri 2006, NM 2006 and AUM 9 were found resistant in first disease screening nursery and second disease screening nursery. Azri 2006 was highly resistant in third disease screening nursery. The varieties/lines 8010, AUM 38 and 7009 were found moderately susceptible to susceptible in all the disease screening nurseries. The rest of the varieties show varied results in all the nurseries. Ten plants, namely sufeda (Eucalyptus camaldulensis), neem (Azadirachta indica), onion (Allium cepa), garlic (Allium sativum L.), shesham (Dalbergia sissoo), akk (Calotropis gigantea), chillies (Capsicum annum), gardinia (Gardenia florida), bakayn (Melia azedarach), ginger (Zingiber officinale) were selected and their extracts against Macrophomina phaseolina. Three concentrations of all the plant extracts were made viz. S, S/2, S/3. Inhibition zone technique was used to study their effect.
