In the current work, A. flavus as an herb endophyte was selected to verify its role as plant growth-promoting and protection such as antimicrobial activity, IAA production, phosphorus solubilization and nutritional improvement of the tomato plant. So far, there is no previous investigation has been done on evaluating the potential of A. flavus as tomato plant growth promotion and to control Alternaria early blight disease of tomato.

The genetic variance of any morphometric or quantitative trait is indicated additive variance (heritable) and non-additive variance and comprise dominance and epistasis (non-allelic interaction) altered by environmental conditions (Iqbal et al., 2014; Kumar et al., 2017; Spaldon and Kumar, 2017).

Early blight is the most devastating disease of tomato it is caused by pathogens i.e. Alternaria solani. In tropical and subtropical countries it creates hazardous effect. It is also a common problem in United Kingdom, Australia, India, Nepal and United States. It is one of the most common foliar diseases of tomatoes. The disease can occur over a wide range of climatic conditions, but is most prominent in areas with heavy dew, rainfall and high relative humidity. Every year sever disease appears in north India.

The yield losses in the range of 48-80 per cent due to early blight (Alternaria solani) damage in tomato were reported from India, Canada, USA and Nigeria (Basu, 1974; Datar and Mayee, 1984; Mathur and Shekhawat, 1986; Sherf and MacNab, 1986; Gwary and Nahunnarao, 1998 and Pandey and Pandey, 2002). The annual economic yield losses due to early blight have been estimated at 79% (Adhikari and Panthee, 2017).

In vitro evaluation of three contact and five systemic and two combination was carried out under laboratory condition in 2018-19 at Department of Plant Pathology, College of Horticulture, Mysuru by using Potato Dextrose Agar medium (PDA) as basal medium and six biocontrol agents were evaluated through dual culture technique. The result revealed that, there was significant difference among the fungicides in inhibiting the radial growth of the A. solani.

The tomato crop attacked by early blight, late blight, leaf spots, anthracnose, Dampimg off, buckeye rot, wilts and root rots. Among these Damping off diseases in tomato caused by Rhizoctonia solani is very common to see in nurseries, an increased incidence of blight caused by Rhizoctonia solani was noticed in recent past in major tomato growing areas of Ranga Reddy district of Andhra Pradesh.

Tomato crop is affected by different fungal pathogens and most devastating pathogen is Alternaria solani causing early blight disease and reducing the yield. Among different new chemical combinations, Azoxystrobin (11%) + Tebuconazole (18.3%) found effective in lowering the disease severity throughout the growing period of the crop.

The experiment on management of early blight of tomato with the new combi molecule was conducted during Kharif 2018 in the bio-resource farm of Institute of organic farming, University of Agricultural Sciences, Dharwad. The new molecule and market sample of Trifloxystrobin 25%+Tebuconazole 50% WG, Azoxystrobin 23% SC, Copper Oxychloride 50% WP were evaluated against early blight incidence. The above chemicals sprayed two times at 15 days interval.

The early blight caused by Alternaria solani is a severe constraint in tomato production and the disease intensity has been increasing day by day for the last few years in India due to changes in the environment. The field experiment was carried out to understand the development of early blight on tomato with respect to weather conditions during kharif 2018-19 at AAU, Anand.

Tomato is one of the most extensively cultivated vegetables and is a rich source of nutrients such as vitamins, antioxidants and minerals for a balanced human diet. World over, early blight (EB) caused by Alternaria solani Sorauer is limiting tomato production and causes great losses. In total, 350 tomato genotypes from ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi were evaluated for early blight resistance under epiphytotic conditions at ICARIndian Institute of Vegetable Research (ICAR-IIVR), Varanasi.

Studies were undertaken to evaluate the plant extracts, fungicides and bio-agents against early blight disease of tomato caused by Alternaria solani under in vitro and vivo conditions. Among the four evaluated plant extracts against A. solani, neem leaf extract at 15% (w/v) was found to be most effective in inhibiting the mycelial growth of the pathogen with inhibition of 52.36 per cent, followed by combination of garlic clove and green chilli extract with the inhibition of 50.42 per cent.

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.

The present investigation was to determine the antifungal ativity of different chitosans and chito-oligosaccharides against Alternaria solani. Out of four chitosans tested, chitosan DA10 and 134 was recorded as 53.44 and 51.47% at 1000ppm, respectively where as at 1500 ppm conc, the inhibition percent was 67.54 and 59.01%, respectively. Among the treatments, chitosans exhibited maximum growth inhibition of pathogen at 1500ppmconcentration.

The efficacy of some fungicides like carbendazim 12 % + mancozeb 63 % WP, difenoconazole 25 EC, propiconazole 25 EC along with commonly used fungicides viz., mancozeb 75 WP, propineb 70 WP, copper-oxy-chloride 50 % WP and one botanical Azadirachta indica (neem) leaf extract (20%) were tested against early blight of tomato cv. Abhinav at Agricultural Research Station, Ladol, Gujarat. A variant with no application of fungicide was used as a control. All fungicide treatments reduce the disease intensity as compared to untreated check.
