In general, soil borne disease i.e. Fusarium wilt is more prevalent in central and peninsular India. Fusarium wilt diseases is soil borne in nature and once it appear in the field it is very difficult to control. In the Maharashtra region, it infects crops at the early growth stage of flowering and at later stages, resulting in yield losses ranging from 11 to 17%. Applying fungicides on frequently, destroyed beneficial microorganisms in the soil that were not intended targets and has led to environmental risks which includes soil and water pollution. As a result, biological control of plant diseases involving fungi antagonistic bacteria may be a practical solution for this serious soilborne disease. Research findings indicate that plants treated with antagonistic microbial consortia exhibited a considerable decrease in disease incidence in contrast to the application of single isolates. Keeping in view the past research work and economic importance of crop the present studies entitled “Evaluation of Bioconsortia against Fusarium Wilt of Pigeonpea (Cajanus cajan L.)” were undertaken during 2021-23.ThesisItem Open Access EVALUATION OF BIOCONSORTIA AGAINST STEM ROT DISEASE (Sclerotium rolfsii) OF GROUNDNUT(MPKV, Rahuri, 2024) Nidheesh B.S.; Narute, T.K.Groundnut (Arachis hypogeae) is one of the major oil seed crop India. It contains an average of 40.1 per cent of fat and 25.3 per cent of protein and every part of groundnut has its own commercial value. In fact, it plays a pivotal role in oilseed economy of India. Several diseases like stem rot, leaf stop, bud necrosis, etc., are responsible for decreasing the quality and quantity of groundnut production. Among them stem rot of groundnut caused by soil borne pathogenic fungi is a major problem and economically important soil borne disease. This pathogen causes yield loss of 20-30 per cent and may reach up to 80 per cent during severe condition. In order to control stem rot disease of groundnut best method is biological method which is efficient and eco-friendly method.ThesisItem Open Access EFFECT OF AZOTOBACTER, ARBUSCULAR MYCORRHIZA ON THE GROWTH AND YIELD OF BRINJAL(MPKV, Rahuri, 2024) Wankhade Harish Prakash; Sonawane, R.

This study involves isolating PGPR (Azotobacter, Bacillus and Pseudomonas) from rhizospheric soil of maize and testing each isolate for morphological, cultural and biochemical characteristics. For their functional potential Azotobacter was examined for nitrogen fixation activity, Bacillus for phosphate solubilization and Pseudomonas for potash mobilization activity respectively. Most efficient strains were used for field studies. Among all the 9 isolates, the strain (AAzt1, ABac2 and APdm3) showed highest N, P and K solubilizing ability in-vitro study were used to prepare consortium on compatible media which is finally further used for field studies. A field experiment was conducted to appraise their effect in combination with graded levels of nitrogen, phosphorous and potassium on growth, and yield of maize (cv. Phule Rajarshi). The field observations were taken on plant height, cob width, cob length, number of cobs/plants, 1000 grain weight, grain yield, nutrient uptake and microbial population.ThesisItem Open Access EVALUATION OF FUNGAL BIOCONSORTIUM FOR THE MANAGEMENT OF BASAL ROT OF ONION (Allium cepa)(MPKV, Rahuri, 2024) Muddada Deepika; Narute, T.K.Onion (Allium cepa L.) is one of the most commonly grown vegetable crops in India. It is a significant agricultural commodity and widely cultivated in various regions of the country. However, onion cultivation in India faces several challenges, with fungal and bacterial diseases being major concern. Among fungal diseases, basal rot caused by Fusarium oxysporum f.sp. cepae can cause significant losses and pose a considerable threat to successful onion cultivation during recent years and hence An investigation was carried out on various aspects such as isolation and identification, symptomology and pathogenicity, cultural and morphological characteristics, and evaluation of fungal bioconsortium under In vitro and In vivo (Pot culture) conditions. The pathogen was isolated from diseased onion bulbs. The pathogenicity of the onion basal bulb rot pathogen was demonstrated using soil inoculation approach. Based on morphological characteristics of the pathogen, the fungus culture was identified as F. oxysporum f.sp. cepae.ThesisItem Open Access STUDIES ON SEED MYCOFLORA OF MAIZE (Zea mays L.)(MPKV, Rahuri, 2024) Bodake Vishal Vardhaman; Suryawanshi, A. V.One of the most significant biotic restrictions on seed production globally is the presence of seed-borne fungus. They are responsible for both pre- and post-emergence death of grains, affect seedling vigour and thus cause some reduction in germination and variation in plant morphology. Microorganisms especially fungi are the largest group which play a vital role in affecting the seeds quality. Early detection of the pathogen is the most crucial step in disease diagnosis and for management programs. The present investigation entitled “STUDIES ON SEED MYCOFLORA OF MAIZE (Zea mays L.)” was undertaken with a view to detect seed borne mycoflora and its impact on seed germination and seedling vigour index (in vitro). Similarly, different fungicides and bioagents were tested against different seed borne mycoflora and their positive effect on seed germination and seedling vigour index in maize (in vitro) were studied.ThesisItem Open Access STUDIES ON SEED BORNE MYCOFLORA ASSOCIATED WITH SEED DISCOLOURATION OF PADDY (Oryza sativa L.)(MPKV, Rahuri, 2024) RASKAR YOGESH TANAJI; Zanjare, S.R.All the isolated pathogens were found pathogenic to paddy seeds resulting into reduction in seed germination and seedling vigour index. The seed borne mycoflora viz., Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Alternaria alternata and curvularia lunata were found more dominant and aggresive. Among all the treatments of fungicides and bioagents, fungicidal seed treatments were found significantly superior in reducing seed borne mycoflora, increasing seed germination and seedling vigour index.
