Mango is regarded as „king of fruits‟ and is grown mainly in tropical and subtropical regions of the world. Anthracnose is one of the devastating disease, known to cause yield loss from 10 to 80 per cent in orchard and also being post-harvest disease, it cause an economical loss to the tune of 15-20 per cent. The disease is caused by the fungal pathogen Colletotrichum gloeosprorioides.

Citrus is India's third-largest fruit crop, boosting production of 1.07 million hectares to 10.48 million tonnes (2013-14). Therefore, yields of 20-25 tonnes/ha have been recorded by some progressive growers, but average productivity is 9.78 tonnes/ha. In other countries where citrus is grown, these numbers are 40-50 tonnes, and the production life in orchards is much longer. High-strength cultivation with automatic fertilization has contributed significantly to the commercial citrus cultivation revolution in many countries.

Mango (Mangifera indica L.) is considered as one of the most popular fruits among millions of people in the tropical and sub-tropical area and increasingly in the developed countries. Anthracnose, caused by the fungus Colletotrichum gloeosporioides, is the most important pre and post-harvest disease of mango.

Use of probiotics for the control of post-harvest diseases has opened new avenue in the management of post-harvest plant pathogens and organic farming. Such probiotics has never been used in the crop production or crop protection programme in Agriculture. The post-harvest pathogens particularly Rhizopus, Aspergillus, Penicillium and Alternaria can be checked as a post-harvest pathogen by sprays of probiotics under natural field conditions when the load of inoculums of these post-harvest pathogens is less in fruits.

Post-harvest mango rot is the main cause of yield loss caused by this disease in Bali. Until now, no environmentally friendly control methods have been found such as finding exophyte microbes that are antagonistic to pathogens. The pathogen found to cause fruit rot disease in mangoes is Lesiodiplodia theobromae.

Extracts of certain plants have been used to control the plant diseases since several years. Here we report in-vitro studies to examine the antifungal activity of aqueous leaf extractsof three plants and neem oil against three post-harvest fungal pathogens viz., Rhizopus arrhizus, Sclerotium rolfsii, Fusarium solani. Among the leaf extracts, Duranta erecta showed maximum antifungal activity against the pathogens, followed by Lasonia inermis, Neem oil, and Cocculus hirsutus. The degree of inhibition increased correspondingly with increasing concentrations of the plant extracts.

Early blight is potentially destructive disease in tomato occurring on the oldest leaves as small, brownish which are due to foliar blight disease and it was caused by a foliar fungal pathogen Alternaria solani. The disease causes considerable yield as well as post-harvest losses. A. solani produced blackish, fluffy mycelium with septate, beaked conidia on PDA Eight plant extracts and four biocontrol agents were evaluated following poison food technique and dual culture.

Khasi mandarin orange is an important horticulture crop in Meghalaya but several losses have been reported due to the post-harvest disease Penicillium rot caused by Penicillium sp. B. subtilis was evaluated for its efficacy against Penicillium sp. under in-vitro. A total of 260 isolates were isolated from samples collected from different habitats of Meghalaya. Twelve B. subtilis isolates were identified by morphological, biochemical and molecular identification and studied for their antagonistic properties against Penicillium sp.

Stem-end rot of mango caused by Lasiodiplodia theobromae and Lasiodiplodia pseudotheobromae is a major post-harvest problem in Manipur and reduces yield. An experiment on antifungal efficacy of three plant extracts viz., Garlic (Allium sativum), Neem (Azadirachta indica) and Ginger (Zingiber officinale) was done through poisoned food technique by taking three concentrations in in vitro conditions against the pathogens and eight Trichoderma isolates viz., T. ovalisporum (KU904456), T. koningiopsis (KU904460), T. harzianum (KU904458), T. atroviride (KU933472), T. harzianum (KU933474), T.

A study was conducted to assess the microbial load on lemon fruits at different postharvest handling stages. After harvesting, there are six different post-harvest handling stages were identified and they are collection, grading, packaging, transportation, wholesaler and retailer stages of fruits. And it was found that the microbial load was suddenly increases at Transportation stage and after it the microbial load continuously increases at subsequent stages i.e. at wholesaler and retailer level. Not only plant pathogenic microorganisms but also the human pathogenic microbes such as E.

Tamilnadu is one of the leading banana grower in the country. Eighty-two per cent of fruit production in India is shared by the banana. Banana fruits after harvest are infected by a series of post-harvest pathogens. Among them, anthracnose disease caused by the pathogen Colletotrichum musae is the very dexterous disease.

Fusarium, Colletotrichum and Penicillium spp. are the well-known pathogen that causes post-harvest plant diseases of the crops. Mainly it influences the fruit crop which plays the most important role in the economy of the many fruit-producing countries, so for the management of these post-harvest pathogens, it should need a specific management strategy. So, keeping in view the study was investigated in the laboratory of the Dept. of Mycology and Plant Pathology, Institute of Agricultural Sciences, BHU, Varanasi.

Studies were undertaken to find out the effect of inoculum load of post harvest pathogen (Penicillium islandicum) on disease initiation, threshold point and population build up of blue mould rot in Indian gooseberry. Inoculations were made on the fruits of Indian gooseberry at five concentrations (10, 50, 100, 200 and 500 spores/ml.). The disease initiation commenced after 54 hrs. of inoculation with inoculum load of 500 spores/ml followed by 200 spores/ml where the initiation of disease was observed after 72 hrs.

The overzealous and indiscriminate use of most of the synthetic fungicides has created different types of environmental and toxicological problems. Recently, in different parts of the world, attention has been paid towards exploitation of higher plant products as novel chemotherapeutants in plant protection. Pyrethroids, and neem products are well established commercially as botanical pesticides and recently some essential oils of higher plants and animals products have also been used as antimicrobials against diseases.

Brinjal (Solanum melongena L.) is an important solanaceous crop of sub-tropics and tropics. The Brinjal is being grown extensively in India. All vegetables have been known to serve as vehicles of human disease for at least a century. Vegetables can become contaminated with microorganisms capable of causing human diseases. This study was designed to determine the microbial load and prevalence of pathogens on surface of Brinjal in local market yards across Junagadh district.
