Effect of Lecanicillium lecanii (Ascomycota: Hypocreales) based silver nanoparticles on seedling emergence, plant growth parameters such as shoot length, leaf surface area, chlorophyll content and phyllosphere microflora of economic important pulses such as cowpea (Vigna unguiculata), black gram (Vigna mungo), green gram (Vigna radiata), sorghum (Sorghum vulgare) and horse gram (Macrotyloma uniflorum) was probed in the present study Moreover the effect on soil heterotrophic microbial populations and soil macronutrients nitrogen, phosphorous and potassium was also investigated. No distinct effect was recorded on seedling emergence, length of the shoot and leaf surface area of all the tested plants. Similarly no effect was observed in the heterotrophic bacterial, fungal and actinomycetes population phyllosphere and chlorophyll content except sorghum. NPK analysis of the treated pot soil showed a sharp increase in phosphate and potassium content than control and no difference in nitrogen level.This study has brought out the safety aspect of nanoparticles to non target organism
