The control of spoilage of plant parts, agricultural, horticultural and sericultural products (Cocoons) by different microorganisms as well as fungi is urgently required to minimize the economic losses caused to the farmers, traders & growers. The different concentrations (0.01, 0.05, 0.1, 0.15 and 0.2 percent) of five antibiotics viz, Tetracycline, Qucin, Ampicillin, Cephalexin and Erthrocin as well as five pesticides like Flash, Atom, Metacid, Triton and Folidol (0.01, 0.05, 0.1, 0.15 and 0.2%) treated against spore germination of three test fungi i.e., Penicillium citrinum, Curvularia lunata and Drechslera. spiciferum. The results exhibited that lower concentrations of both the antibiotics and the pesticides induced poor inhibitory effect on spore germination of all the three fungi, however, higher concentrations of antibiotics and pesticides showed maximum percent inhibition of spore germination of three fungi. But maximum percent inhibition of spore germination of three fungi observed at 0.2% concentration treated with Tetracycline & Qucin. Similar result was observed due to two pesticides i.e. Metacid and Atom at 2% concentration.
