Several foliar and stalk rot diseases affect maize crops. The illness affected the majority of the cultivars that were issued. The influence of overuse of chemical fungicides on the environment and food safety has become a serious problem with the rise of ecological agriculture. Epiphytes are phyllosphere residents who can include a wide range of bacteria and filamentous fungi. Microbial interactions in the phyllosphere repress and promote plant pathogen colonisation and infection of tissues, increasing disease resistance and agricultural crop productivity, implying that phyllosphere microorganisms can play a key role in growth promotion and disease suppression. Bacteria from individual colonies were studied. Individual colony bacteria was examined for shape, size, colour, Gram staining, endospore staining, elevation and texture for morphological studies. Different bioc...

Tomato crop is very often affected by several diseases incited by pathogens such as fungi, bacteria, viruses and nematodes. Among all the fungal diseases that infect tomato, Fusarium wilt of tomato caused by Fusarium oxysporum f. sp. lycopersici (Fol), is one of the most serious and destructive diseases across the world causing severe economic losses, wherever tomato is grown. Due to prolonged survival of Fol in the soil as saprophyte and overcoming the challenging conditions by producing resistant structures, it has become very difficult to manage the disease. The most feasible method for managing Fusarium wilt disease of tomato is by usage of effective fungicides. Ten fungicides viz., Copper oxychloride 50%WP, Mancozeb 75% WP, Carbendazim 12% + Mancozeb 63% WP, Metalaxyl 4% + Mancozeb 64% WP, Hexaconzole 5% + Captan 70% WP, Thiophanate Methyl 70% WP, Thiophanate Methyl 45% + Pyraclostrobin 5% FS, Tebuconazole 250 E.C, Tebuconazole 50% + Trifloxystrobin 25% WP and Azoxystrobin 23% SC were evaluated against Fol under in vitro conditions at three concentrations i.e. 500, 1000 and 1500 ppm. Three replications were maintained for each treatment with control. Tebuconazole 50% + Trifloxystrobin 25% WP was found to be the most effective fungicide followed by Tebuconazole 250 E.C with high fungitoxicity against Fol. Azoxystrobin 23% SC was the least effective. The results of this present investigation will be helpful for future research on fungicide management for Fusarium wilt of tomato.

At NARDI, these bioagents were mass-produced and distributed to different villages of eight important districts of A.P. so as to popularize them. Application of T. viride found to reduce plant mortality considerably in cotton and chilli from 18% (before distribution) to 3% in the subsequent years. Inundate releases of T. chilonis remarkably reduced the incidence of cotton bolloworm Helicoverpa armigera (Hubner) and sugarcane early shoot borer Chilo infuscatellus (Snell) to the extent of 43% and 82% respectively. The usage of pesticides and fungicides also come down. Consequent to this, farmers realized better yield and developed positive attitude towards adoption of T. viride and T. chilonis as a component of IPM. In an attempt to identify the constraints faced by the farmers for using bioagents, indequate supply of tricho cards (65%) and distance...

Among them, Alternaria leaf spot caused by Alternaria spp. is predominant in causing economic losses to the cotton crop in the country. Phyllosphere inhabitants termed as epiphytes may consists of a variety of bacteria and filamentous fungi. They also play a key role in carbon and nitrogen cycling and help in important environmental processes such as methanol degradation and nitrification. So, bacterial phyllosphere cultures (P1 to P8) were isolated from the Bt and non Bt cotton by leaf imprint method and dilution method. The colony characters of isolates of bacteria pertaining to their shape, size, elevation, margin, texture, appearance and pigmentation were recorded. Gram's staining and endospore staining revealed that P1, P2, P3, P5, P8 were Gram positive, P1, P2, P5 were showing endospore staining and P1, P4, P6, P7 were rod shaped. Biochemical tests revealed that the eight isolates Bt and non Bt cotton were differed in each test and showed positive for the catalase and oxidase test. The isolates P1, P5 and P6 showed positive results to Voges proskauer test. Isolates P2, P4 and P6 revealed positive results of phyllosphere bacteria to Indole test. Whereas, isolates P1, P2 and P8 showed negative reaction to methyl red test. The phyllosphere bacterial isolates P3, P5 and P7 recorded negative reaction to gelatin liquefaction. Screening of phyllosphere microflora against Alternaria macrospora was conducted following dual culture technique for all the isolates. Phyllosphere bacterial isolate P5 recorded maximum growth inhibition with 57.41 per cent followed by P4 isolate with 53.52 per cent growth inhibition over the test fungus Alternaria macrospora. Whereas least per cent growth inhibition was reported in isolate P6 with 45.63 per cent.

Among the botanicals, neem leaf extract was found to be superior in inhibiting the growth of the test pathogen at 5 and 10% concentration followed by garlic clove extract. In vitro screening of four bioagents against the pathogen indicated superiority of Pseudomonas fluorescens as a potential antagonist. Glasshouse experiment revealed that seed treatment with carbendazim (0.1%)+ neem leaf extract (10%) + P. fluorescens (10g kg−1seed) was found to be superior to other seed treatments in reducing the disease and seedling mortality, which recorded maximum germination (90%), seedling vigour index (2105) and least wilt incidence of 22.5 per cent at 35 days after sowing under glasshouse conditions. The next best was seed treatment with carbendazim (0.1%) followed by P. fluorescens (10g kg−1seed), which recorded germination of...

The correlation coefficient analysis shown fruit yield per plant exhibited maximum positive association with number of fruits per plant (0.8997), marketable yield per plant (0.6300), number of branches per plant (0.2293), fruit diameter (0.1339), fruit weight (0.1233), days to first flowering (0.1176). Path coefficient analysis shown maximum positive direct effect on fruit yield per plant through days to first fruit harvest (1.1811G), number of fruits per plant (0.8929G, 0.9813P), fruit weight (0.7588G, 0.3485P), days to last fruit harvest (0.3340P), days to first flowering (0.2431G) and number of branches per plant (0.2278G). Hence, direct selection can be done by considering these traits as the main criteria to overcome indirect effects for develop...

Among them, Alternaria leaf spot caused by Alternaria spp. is predominant in causing economic losses to the cotton crop in the country. Phyllosphere inhabitants termed as epiphytes may consists of a variety of bacteria and filamentous fungi. They also play a key role in carbon and nitrogen cycling and help in important environmental processes such as methanol degradation and nitrification. So, bacterial phyllosphere cultures (P1 to P8) were isolated from the Bt and non Bt cotton by leaf imprint method and dilution method. The colony characters of isolates of bacteria pertaining to their shape, size, elevation, margin, texture, appearance and pigmentation were recorded. Gram's staining and endospore staining revealed that P1, P2, P3, P5, P8 were Gram positive, P1, P2, P5 were showing endospore staining and P1, P4, P6, P7 were rod shaped. Biochemical tests revealed that the eight isolates Bt and non Bt cotton were differed in each test and showed positive for the catalase and oxidase test. The isolates P1, P5 and P6 showed positive results to Voges proskauer test. Isolates P2, P4 and P6 revealed positive results of phyllosphere bacteria to Indole test. Whereas, isolates P1, P2 and P8 showed negative reaction to methyl red test. The phyllosphere bacterial isolates P3, P5 and P7 recorded negative reaction to gelatin liquefaction. Screening of phyllosphere microflora against Alternaria macrospora was conducted following dual culture technique for all the isolates. Phyllosphere bacterial isolate P5 recorded maximum growth inhibition with 57.41 per cent followed by P4 isolate with 53.52 per cent growth inhibition over the test fungus Alternaria macrospora. Whereas least per cent growth inhibition was reported in isolate P6 with 45.63 per cent.
