Twenty six isolates of P. agglomerans, two reference strains of P. agglomerans (DWM-1and DWM-2) and three out group bacteria viz., Bacillus subtilis DTBS-5, B. cereus JHTBS-7, and Pseudomonas fluorescens DTPF-3 were taken to study genetic diversity by using BOX–PCR primers. Extracellular enzyme activities of the bacteria were determined. which has a wide host range is an important fungal pathogen causing losses in yield in agricultural crops. Among the isolates of A.solani, different culture media were exhibited variation in respect of colony colour, substrate colour, growth pattern, margin colour, topography, thickness of mycelium and sporulation. The antagonistic microorganisms against the fungal pathogens were observed by Dual Culture Technique and antibiotic interaction. Present research was carried out to study the effect of different culture media and pH on mycelia growth of Alternaria solani. 2). The intensity of light, duration of exposure, temperature at the time of exposure and scraping the cultures have a considerable effect on spore yield and spore dimensions. Among the plant extacts, Allium sativum gave maximum inhibition of mycelial growth followed by Crotalaria juncea and Azadirachta indica, while Euphorbia hirta was showed least mycelium inhibition. kurstakii (FDP-41, BAB-410), 1 strain of Bacillus subtilis (EK-7), 1 strain of Pseudomonas chlororaphis (NEM-28) and 1 strain of Bacillus sphaericus GC sub-group D (FD-49) and additionally 1 Beauveria bassiana (ET 10) fungus isolate were examined for their insecticidal activities in this study. Singh V., P. Kumar and A. P. Sinha. Chitinase and glucanase enzyme activity of all the tested bacteria was positive. PhD. isms. ha mancozeb (1 kg ha) and Pseudomonas fluorescens (10 kg ha) were evaluated for their efficacy in inducing defense enzymes in tomato against Alternaria solani and Septoria lycopersici. (STUDIES ON Alternaria solani CAUSING EARLY BLIGHT DISEASE IN TOMATO (Lycopersicon esculentum Mill.)). The present research was carried out to study in vitro evaluations of native Trichoderma spp., botanicals and fungicides against Alternaria solani causing Early blight of tomato which induces losses in Manipur. The symptoms of early blight of tomato were first observed as small brown water soaked lesion on the older leaf. S., Mohan, Kumar, S.P., Kevin Myers, L., Fry, W.E., Squires, J.N. Among two organisms, Bacillus spp (36.7%) was found to have more antagonistic activity against test pathogens. of galls/25seedlings (17.50) and maximum seedling height (27.6cm) were observed in Bacillus. These isolates were then transferred to the test tubes, containing PDA, and were stored at + 4°C for later, containing a mixture of peat enriched in organic ma-, terial and perlite in equal amounts, and kept in plant, hours light cycles. Bioscan. 113(1), 8-13. Consequently, they were multiplied using, TATGC-3') which target ITS1-5.8s-ITS2 ribosomal, DNA region, an area commonly used in molecular, identification of microfungi [18]. Among the biotic stress Early blight caused by Alternaria solani inflicts tremendous losses to the crop. Biological control. fruit weight. Journal of Chemical and Pharmaceutical Research. With the emergence of negative effects of chemicals on humans and environment and with the increasing awareness on environmental conscious, alternative methods were sought to cope with diseases ; and in this context, successful results were obtained by conducting studies to suppress pathogens with fungi, which may be employed in biological control.

Protocol for conidia production of Alternaria solani. This is the first report demonstrating that P. fluorescens and P. mediterranea cause pith necrosis on tomato in Turkey. Plant material, pathogen fungi, biocontrol, in the study was a tomato variety with the trade name, genic fungus was obtained from plants showing, symptoms of early blight, which were collected from. Six bacterial and 1 fungal isolates that showed the highest efficacy in in vitro were then tested in in vivo.

The biochemical approach described in this paper with tomato should provide the basis for further efforts concentrating on the isolation and characterization of elements involved in perception and in the early steps of intracellular signal transduction. The pathogen showed maximum growth and sporulation at 25-30°C temperature. The activity of defense enzymes peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL), β-1, 3 glucanase, The present research deals with the study of antagonistic effect of microorganism against black root rot disease caused by Fusarium oxysporum and collar rot disease caused by Rhioctonia solani.

Strains belonging to five different Pseudomonas species, i.e. A 20 mg L-1 crystal violet solution was decolorized by 90.88 % in 11 days. their efficacy on the yield components and yield of tomato plants infected with A. solani. To reduce the impact of the disease, a timely prediction of a disease outbreak is important. As positive, control, pathogenic fungus was used alone. Depending on the environment, the conidia are dispersed differently. In the study, 3 petri plates, In order to determine the effect of biocontrol, genic fungus, the mycelial discs of these isolates, with a 4 mm in diameter were placed on Petri plates, containing PDA, leaving 5 cm distance from the, cubation.

It produces numerous polyketides such as solanapyrone A ( 50 ) and alternaric acid ( 51 ), and is thus an ideal target species for speculative PKS gene-fishing expeditions ( Figure 4 ). Alternaria solani: Extremely common, causing “early blight” in tomatoes and potatoes. Alternaria solani was identified as the pathogen of early blight disease on the basis of morphological characters and pathogenicity test. Among seven culture media that were tested, the fungus grew best on Richards agar, OatMeal Agar and Coon's media.

Alternaria species, including A. solani and A. alternata, are a serious threat to potato cultivation and cause necrotic leaf spots, leading to premature defoliation and yield losses. During application of, fungus suspension, a drop of Tween 20 was added to, the suspension to help with homogeneous distribu-, tion of the spores. Worldwide, modelling attempts have been made to predict the occurrence of Alternaria in order to take adequate measures. Alternaria solani was identified as the pathogen of early blight disease on the basis of morphological characters and pathogenicity test.
