Root Rot Disease Incited by Macrophomina phaseolina in Arid Legumes and their Management: A Review

Macrophomina phaseolina (Tassi) Goid. is a soil- and seed-borne pathogen that causes charcoal rot various rots blights of more than 500 crop species. Dry root (DRR) also called as which yield loss ranged from 25-48 per cent. The necrotroph infects wide range crops. It observed mycelium M. in cotyledons, plumule radicle, the naturally infected seeds mungbean cowpea. disease symptoms are clearly visible time emergence can be evaluated at stages development plant. mechanical plugging xylem vessels by microsclerotia, toxin production, enzymatic action pressure during penetration lead to development. Management aim reduce number sclerotia soil or minimize contact inoculum host. Soil solarization cost-effective method for management borne diseases. Disease suppression biocontrol agents such Trichoderma harzianum, T. viride Bacillus subtilis sustained manifestation interactions among plant, pathogen, agent, microbial community on around plant physical environment considerably inhibited growth phaseolina. Essential oils extracts contain multitude bioactive substances against fungi, bacteria nematodes. has been reported neem oil, turmeric garlic was effective vitro condition. Chemical control an when seed treatment foliar spray carbendazim, topsin M-70, captan, thiram, mancozeb, copper oxychloride leaf blight (Macrophomina phaseolina) phaseolina). As non-chemical alternative methods time-consuming less soilborne pathogens. controlling some diseases agricultural Varoius workers compatibility with fungicides found Carbendazim viride, harizianum were under pot
