The results obtained that on the different straw prepared compost, spawn run was found significantly fastest (13.30 days) in wheat straw while, the days required for pinhead initiation was less (15.60 days) in combination of wheat straw + paddy straw. The yield attributing characters did not differed significantly and the number of fruiting bodies varied from 23.60-31.00. The fresh yield of button mushroom on different straw prepared compost, significantly maximum (560g) with 11.2 % biological efficiency was recorded in combination of wheat straw + paddy straw.

The flavor and aroma of the food due to the use of spices creates an indelible experience. Among the commonly utilized spices to stimulate the taste buds in Indian food, chilli constitutes an inevitable position. Chilli is the major spice crop, accounting for about 30 per cent of total spice production in the country. Besides being a vital ingredient of of Indian food, chilli contributes major share in Indian economy. Chilli also has uncountable benefits to human health. Fresh green chilli fruits contain more Vitamin C, while red chilli fruits have more Vitamin A content. India has been one of the major producers and exporters of chilli. The decline in chilli production has been attributed to the diseases associated with chilli crop. Anthracnose disease is one of the major economic constraints to chilli production regions and it is gaining much attention towards causes of damage. The disease causes damage to both mature fruits in the field as well as during their storage under favorable conditions. This review gives an account of the identification of Colletotrichum capsici. Also, the review highlights the various management strategies for the causal agent of the disease, associated with the chilli anthracnose.

About 83 mushroom flora/fungal genera of edible, non-edible, medicinal, poisonous, mycorrhizal mushrooms were collected from litter, soil, termite mounds, wood logs, live plants and rotten leaves across dense stretches of forests of Bastar, Amarkantak, Jagdalpur, Ambikapur to name a few and also from various market areas of different districts cutting across Chhattisgarh. All stages of Rhizopogon sps. and Termitomyces sps. (Kanki Futu) were observed in in-situ conditions. The market survey was also conducted and it was found that Termitomyces and Rhizopogon were sold in abundance at very high prices across Chhattisgarh. The other edible macrofungi collected and isolated from forests were Calocybe indica (milky mushroom), Volvariella volvaceae (Paddy straw mushroom), Pleurotus djamor, Pleurotus ostreatus, Pleurotus florida and Hypsizygous ulmarius. Few macrofungi as mycorrhizal partners, bioabsorbents, decomposers and storehouses of medicinal biomolecules were also collected, characterized and stored. However many issues relating to their taxonomy and phylogeny, ecology, and geographical distributions remain unclear.

Among these microbial metabolites, antibiotics produced by different bacteria and fungi are now proving to be a new source of potential biopesticides. Various actinomycetes like Streptomyces, Actinoplanes, Actinomadura, Micromonospora, Streptosporangium, Streptoverticillium and Spirillospora, bacteria belonging to the genera Agrobacterium, Bacillus, Burkholderia, Enterobacter, Erwinia, Lysobacter, Pseudomonas, Serratia and a few fungal genera such as Ampelomyces, Aspergillus, Coniothyrium, Gliocladium, Laetisaria, Penicillium, Phlebiopsis, Sporodesmia, Talaromyces, Tilletiopsis, Trichoderma, Trichothecium and non-pathogenic Fusarium are prolific producers of secondary metabolites which at low concentrations are lethal to the growth or metabolic activities of other microorganisms. Phenazine-1-carboxylic acid, pyocyanin, 2,4-diacetylphloroglucinol, pyoluteorin, pyrrolnitrin, hydrogen cyanide, siderophores, zwittermicin a 14, kurstakin, azole compound, ammonia, wuyiencin, viridin, trichodermin, 6-pentyl-2h-pyran-2-one, gliovirin, gliotoxin, harzianopyridone, harzianolide, massoilactone and d-decanolactone, viridepyronone, koningins, t22 azaphilone, t39 butenolide, volatile compounds and trichothecin are some of the metabolites which have been used in plant disease control. These microbial metabolites can be used as a substitute for chemical fungicides and paved way for its use in sustainable agriculture as biopesticides.
