ANTAGONISTIC POTENTIAL OF DIFFERENT TRICHODERMA SPP. AGAINST SCLEROTIUM ROLFSII AND FUSARIUM OXYSPORUM F. SPP. LYCOPERSICI
type: item
description: Tomato (Solanum lycopersicum L.) is one of the most widely cultivated vegetable crops worldwide and is valued for its nutritional and economic importance. Often referred to as the “poor man’s orange” due to its high vitamin C content, tomato cultivation has expanded considerably; however, its production is severely constrained by soil-borne pathogens such as Fusarium, Rhizoctonia and Sclerotium species. Soil samples were collected from different tomato-growing regions of Parbhani district, Maharashtra, and six native Trichoderma isolates were obtained from the tomato rhizosphere. Based on morpho-cultural characteristics, the isolates were identified as Trichoderma harzianum, Trichoderma asperellum, Trichoderma virens, Trichoderma koningii, Trichoderma longibrachiatum and Trichoderma hamatum. These isolates were evaluated under in vitro conditions against Sclerotium rolfsii and Fusarium oxysporum f. sp. lycopersici using the dual culture technique. Among the tested isolates, Trichoderma harzianum (T₁) proved to be the most effective against Sclerotium rolfsii, recording the lowest mycelial growth of 15.50, 18.33 and 27.65 mm on the third, fifth and seventh days, respectively, followed by Trichoderma asperellum (T₂), which showed 16.03, 19.04 and 28.17 mm colony diameter. Against Fusarium oxysporum f. sp. lycopersici, Trichoderma harzianum (T₁) again exhibited the highest antagonistic activity, recording minimum mycelial growth of 30.12, 23.96 and 30.12 mm on the third, fifth and seventh days, respectively, with maximum inhibition of 52.09, 61.06 and 66.53 per cent. The study demonstrates the strong biocontrol potential of native Trichoderma species, particularly Trichoderma harzianum, against major soil-borne pathogens of tomato, indicating their suitability for eco-friendly disease management strategies.

IN VITRO EVALUATION OF NEWER FUNGICIDES AND BIOCONTROL AGENTS AGAINST CHILLI DAMPING OFF
type: item
description: Chilli (Capsicum annuum L.) is one of the most widely grown vegetable crops and is extensively used as a spice crop throughout the world. The chilli crop is affected by several diseases such as damping-off, wilt, anthracnose, die-back, root rot and bacterial wilt. Among the fungal diseases, damping-off caused by Pythium aphanidermatum (Edson) Fitzp. in nurseries is a major constraint in chilli production, resulting in up to 62% seedling mortality and accounting for nearly 90% plant death either as pre- or post-emergence damping-off under nursery conditions. Traditionally, the disease is managed using synthetic fungicides such as metalaxyl and carbendazim; however, their repeated use often leads to phytotoxicity and environmental concerns. This has created a need to evaluate newer fungicide formulations and eco-friendly alternatives for effective disease management. The present study was undertaken to evaluate the efficacy of newer fungicides and biocontrol agents against chilli damping-off disease. The results revealed that Metalaxyl-M 4% + Mancozeb 64% WP, Trifloxystrobin 25% + Tebuconazole 50% WG, and Mancozeb 64% + Cymoxanil 8% WP were the most effective treatments, showing 100% inhibition of the pathogen at the recommended concentration. Among the biocontrol agents tested, Bacillus subtilis and Pseudomonas fluorescens showed the highest antagonistic activity against the pathogen, recording 71.30% and 68.52% inhibition, respectively. The study indicates that newer fungicide combinations and selected biocontrol agents can be effectively utilized for managing damping-off disease of chilli in an eco-friendly and sustainable manner.

ISOLATION, CHARACTERIZATION AND MANAGEMENT OF PYTHIUM APHANIDERMATUM CAUSING SOFT ROT OF GINGER
type: item
description: Ginger (Zingiber officinale Rosc.), an important spice crop cultivated extensively in tropical and subtropical regions, is severely affected by soft rot disease caused by Pythium aphanidermatum. The present study was undertaken to isolate and identify the causal organism from infected ginger rhizomes collected from farmers’ fields and to evaluate the efficacy of different biocontrol agents against the pathogen under in vitro conditions. The pathogen was successfully isolated on potato dextrose agar (PDA) and identified based on its cultural and microscopic characteristics. Pathogenicity of P. aphanidermatum was confirmed using rhizome inoculation methods, including rhizome dip, rhizome injection and soil inoculation techniques. Eight biocontrol agents comprising six fungal agents, namely Trichoderma asperellum, Trichoderma harzianum, Trichoderma virens, Aspergillus niger, Metarhizium anisopliae and Paecilomyces lilacinus, and two bacterial agents, Bacillus subtilis and Pseudomonas fluorescens, were evaluated against the pathogen using the dual culture technique. Among the tested biocontrol agents, Trichoderma asperellum was found to be the most effective, recording 70.36% inhibition of mycelial growth of P. aphanidermatum. The results indicate that fungal biocontrol agents, particularly Trichoderma asperellum, can serve as eco-friendly and sustainable alternatives to chemical fungicides for the management of soft rot disease of ginger.

IMPROVEMENT IN PCR-BASED SIMULTANEOUS DETECTION OF DIVERSE DNA VIRUSES IN BANANA ( CV. CAVENDISH MUSA ACUMINATA)
type: item
description: Banana production is increasingly threatened by viral pathogens, particularly Banana bunchy top virus (BBTV) and (CMV). These viruses reduce crop yield and quality, making the early and accurate detection of infections critical for effective disease control. BBTV symptoms can take between 25 to 85 days to appear following transmission by aphids ( ), which complicates timely diagnosis. In this study, a PCR-based assay was developed to simultaneously detect BBTV and CMV by targeting conserved regions of their respective movement protein (MP), replication-associated (Rep), and coat protein (CP) genes. Banana leaf samples were collected from major cultivation areas across different agroclimatic zones in Maharashtra. An internal control was included to ensure the reliability of PCR amplification. The method proved effective for rapid and specific virus identification, offering an improvement over single-gene PCR by minimizing false positives. This diagnostic approach can support routine screening programs to ensure the propagation of virus-free planting material, thereby enhancing disease management and improving yields in Banana

ECO FRIENDLY MANAGEMENT OF PYTHIUM APHANIDERMATUM CAUSING DAMPING OFF IN CHILLI UNDER LABORATORY CONDITIONS
type: item
description: Chilli is a vital spice and vegetable crop that suffers significant yield losses due to damping-off disease, primarily caused by Pythium aphanidermatum. The present study was undertaken to evaluate the efficacy of selected botanical extracts and microbial bioagents against this pathogen under in vitro conditions. The pathogen was isolated from infected chilli seedlings and identified based on morphological characteristics. Aqueous extracts at 10% and 20% concentrations from seven botanicals were evaluated using the poisoned food technique, while the antagonistic potential of five fungal and two bacterial bioagents was assessed using the dual culture method. Among the botanicals, Zingiber officinale (ginger) and Allium sativum (garlic) exhibited complete inhibition (100%) of mycelial growth at both concentrations. This was followed by Curcuma longa (turmeric) and Allium cepa (onion), which showed moderate inhibitory effects. Azadirachta indica (neem) and Datura stramonium (datura) were found to be the least effective. Among the bioagents, Trichoderma harzianum (Parbhani isolate) exhibited the highest antagonistic activity with 55.03% inhibition of mycelial growth, followed by Trichoderma asperellum (52.88%) and Trichoderma harzianum (Sambhajinagar isolate) with 50.50% inhibition. The bacterial bioagents, particularly Pseudomonas fluorescens and Bacillus subtilis, showed comparatively lower inhibitory effects. The study indicates that certain botanicals and fungal biocontrol agents, especially Zingiber officinale, Allium sativum, and Trichoderma harzianum, have significant potential for the eco-friendly management of damping-off disease in chilli.

COMPATIBILITY STUDY OF TRICHODERMA SPECIES WITH NEWER FUNGICIDES AND ITS EFFECT ON SOIL BORNE PATHOGENS
type: item
description: Based on their ability to suppress plant pathogens and enhance nutrient uptake by plants, Trichoderma spp. are widely known as effective biocontrol agents. The present investigation was undertaken to study the compatibility of four Trichoderma species, namely Trichoderma harzianum, Trichoderma asperellum, Trichoderma koningii and Trichoderma hamatum, with five commonly used fungicides. The fungicides tested were Thiophanate methyl + Pyraclostrobin, Carbendazim + Mancozeb, Carboxin + Thiram, Metalaxyl + Mancozeb and Tebuconazole. Each fungicide was evaluated at three concentrations, viz. recommended dose, 50% of recommended dose and 25% of recommended dose. The results revealed that mycelial growth of Trichoderma spp. was affected differently by the fungicides at various concentrations. Among the fungicides tested, Metalaxyl + Mancozeb was found to be compatible with all four Trichoderma species, showing the least inhibition at 25% of the recommended dose (0.05% concentration). The remaining four fungicides exhibited incompatibility with all Trichoderma isolates at all three concentrations tested. Carbendazim + Mancozeb and Tebuconazole caused complete (100%) inhibition of all Trichoderma spp. at all doses. Among the tested biocontrol agents, Trichoderma asperellum and Trichoderma harzianum were found to be more effective against soil-borne pathogens such as Rhizoctonia bataticola, Fusarium oxysporum and Sclerotium rolfsii. The study highlights the importance of selecting compatible fungicide–biocontrol combinations for integrated disease management strategies.

DETECTION OF SEED BORNE MYCOFLORA OF WHEAT
type: item
description: Detection of seed-borne mycoflora of wheat (Triticum aestivum L.) was carried out during 2024–25 at the Department of Plant Pathology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth (PDKV), Akola. The study aimed to identify the seed-borne mycoflora associated with different cultivars of wheat. Four incubation techniques, namely the standard blotter method, agar plate method, 2,4-D blotter method, and rolled paper towel method, were evaluated for their efficiency in detecting seed-borne fungi. A total of eight seed-borne fungal species were identified, namely Cladosporium cladosporioides, Alternaria alternata, Fusarium moniliforme, Curvularia lunata, Bipolaris sorokiniana, Aspergillus niger, Aspergillus flavus, and Rhizopus spp. Among the incubation methods, the agar plate method recorded the highest frequency of seed-borne mycoflora (93.25%), followed by the standard blotter method (87.00%), whereas the 2,4-D blotter method recorded 59.00%. The rolled paper towel method recorded the lowest detection of seed-borne mycoflora (35.75%). The standard blotter method proved most effective in detecting Cladosporium cladosporioides (23.00%) and Alternaria alternata (20.50%), while the agar plate method efficiently detected Curvularia lunata (13.75%) and Bipolaris sorokiniana (8.50%). Lower frequencies were observed for Aspergillus spp. and Rhizopus spp. across all incubation methods. It was concluded that the agar plate method and standard blotter method were more efficient for routine detection of seed-borne fungi in wheat. These methods are therefore recommended for seed health testing to ensure phytosanitary quality and disease-free seed production in wheat.

MANAGEMENT OF SEED BORNE MYCOFLORA WITH TRICHODERMA BASED COPPER NANOPARTICLES (CUNPS)
type: item
description: Biosynthesized -based copper nanoparticles (CuNPs), obtained from the Department of Plant Pathology, PDKV Akola, were evaluated for their effects on soybean ( L. Merrill) seed performance. Seed treatments were applied at concentrations of 10 ppm, 50 ppm, 100 ppm, 150 ppm, 200 ppm, and 250 ppm, and assessed for their impact on seed germination, root length, shoot length, seedling vigour index, and pre- and post-emergence mortality. The results indicated that seed treatment with -based CuNPs at 10 ppm was the most effective concentration, significantly reducing the adverse effects of seed- borne mycoflora and promoting optimal seedling growth. Specifically, this concentration enhanced seed germination and seedling vigour while minimizing both pre- and post-emergence mortality. In contrast, higher concentrations (@ 50 ppm) of -based CuNPs exhibited phytotoxic effects, leading to a reduction in germination rate, root and shoot growth, seedling vigour, and an increase in mortality. These findings suggest that lower concentrations of biosynthesized CuNPs are beneficial for seed treatment, whereas elevated doses may exert detrimental effects on soybean seedling development.
