Abstract
Physiological changes and mode of resistance in Bipolaris oryzae to ed ifenphos was evaluated. Due to development of resistance, protein, DNA , RNA, total lipid and phospholipid contents were altered. Rate of eff lux of electrolytes was decreased and reduced membrane permeability wa s suggested as the mechanism of resistance. Due to reduced membrane pe rmeability, rate of uptake of edifenphos was also less in resistant st rains of B. oryzae.
