Impact of plant age on phyllospheric mycoflora of conventional and organic cotton fields

Shrikant B. Mane, Ashok M. Chavan

Abstract :

 The phyllosphere is considered as suitable habitat for microorganisms, which is predominantly characterized by variable environmental conditions i.e. light, temperature, humidity and nutrient availability. The ability of microorganisms to immigrate and to colonize this environment mainly determines the composition of microbial phyllosphere communities. Immigration and colonization by the microorganisms in turn is linked to their ability to adapt to or to tolerate the adverse conditions in the phyllosphere. Total fungal population was higher in organic cotton fields with the age of cotton plant as compare to conventional cotton fields; While Pathogenic fungal population was higher in conventional cotton field as compare to organic one. Alternaria alternata, Alternaria macrospora, Aspergillus flavus, Aspergillus niger, Cercospora gossypina, Colletotrichum gossypii, Curvularia lunata, Drechslera tetramera, Helminthosporium gossypii, Penicillium notatum, Penicillium chrysogenum, Rhizoctonia solani, Stemphylium solani, Rhizopus oryzae, Trichoderma harzianum and Trichoderma viride were reported. It was reported that Alternaria, Penicillium and Aspergillus were the most common fungi observed in both the farming systems at crop maturity.
