Abstract :
The mushroom has characteristic appearance and edibility. It occurs seasonally all over the world in various habitats. Of this large heterogeneous group more than two thousand edible species, 300 species belonging to 70 genera are reported from India. Out of 2000 species of edible mushroom about 80 have been grown experimentally, 20 cultivated commercially and 4 or 5 species produced on industrial scale throughout the world. Since few decades ago, the mushroom cultivation is emerging out as an agro-based industry which can help the landless, small and marginal farmers to raise income and can create gainful employment to weaker sections of the society. In our country, at present three important types of mushrooms are being cultivated. These are Button mushroom (Agaricus bisporus and Agaricus bitorquis), Straw mushroom (Volvariella volvaceae) and Oyster mushroom (Pleurotus species). Button mushroom needs very low temperature for its cultivation. Therefore, only cool climatic areas and winter season in the plains of Northern India are suitable for its cultivation. Pleurotus sajor-caju is known to be second in total production of mushrooms. This mushroom needs comparatively high temperature with optimum range between 25oC-27oC for mycelial growth and 19oC to 21oC for fruiting.
Nowadays farmers in the country are very worried about the susceptibility of mushroom crop towards pathogenic attack. Literature survey reveals that, azoles and their imidazole blend were found to be very instrumental in controlling the diseases in the field of agriculture. Blends of imidazole with the chloro substituted azoles served as a component in the manufacture of many pesticides and growth regulatory agents therefore received great importance in the agricultural fields. Owing to their important properties, we thought it worthwhile to study the efficacy of newly synthesised heterocycles towards growth promoting and disease controlling impact on Oyster mushroom spp.
