Tomato is world’s one of the largest growing vegetable crop and ranks first among processing crops. It’s production suffers with many biotic and abiotic factors. Leaf blight disease caused by different species of Alternaria is one of the most dreadful diseases of tomato, causing huge economic losses. The present study was conducted in order to evaluate the efficacy of different fungicides against Alternaria alternata, one of cause for blight disease of tomato.

Grain mold is economically important disease of sorghum. For Management of sorghum grain mold various chemicals were screened for efficacy and management of grain mold under field conditions. Four different fungicides viz., Hexaconazole, carbendazim, thiram+mancozeb, propiconazole and two control treatments i.e. one water spray and one absolute control were evaluated for control of sorghum grain mold.

Different non systemic and systemic fungicides are tested at four concentrations under in vitro over Macrophomina phaseolina causing charcoal rot of soybean. Among seven non systemic fungicides, mancozeb 75% WP and propineb 70% WP were found to be the most effective fungicides with cent per cent mean mycelial inhibition at all concentrations (1000, 1500, 2000 and 2500 ppm) tested.

Many systemic and non-systemic fungicides were reported to manage the powdery mildew of capsicum. The information on the efficacy of new fungicides against powdery mildew of capsicum is insufficient. By considering the seriousness of disease and the economic damage/exorbitant losses caused by the disease, the present investigation was carried out by using integrated management approach using new molecule fungicides, botanicals and organic amendments for their efficacy to suppress powdery mildew of chilli under field condition.

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 the present study nine fungicides were evaluated against the false smut disease of rice during kharif-2016. Among the different fungicides tested azoxystrobin (18.2 %) SC + difenconozole (11.4 %) SC and metiram (55 %) WG + pyraclostrobin (5 %) WG @ 0.1 per cent recorded the least disease severity of 1.85 and 2.52 per cent respectively, followed by propiconazole 25 EC, Azoxystrobin 25 % SC, Difenconazole 25 % EC, tebuconozole 250 EC and flusilazole (25 %) SE + carbendazim (12.5 %) SE showed better efficacy at 0.1 per cent and enhanced the paddy yield under field condition.

The toxicants (fungicide and botanicals) showing maximum efficacy against the pathogen and minimum efficacy against milky mushroom (Calocybe indica) mycelia as per results of in vitro studies were further evaluated against T. harzianum under in vivo condition in mushroom house. Among fungicides only Bavistin (@150 ppm) and out of three botanicals only Nimbicidin (@4 per cent) were selected for management of the green mould disease in milky mushroom cultivation in bags.

The cluster bean (Cyamopsis tetragonoloba L.Taub.) also known as Guar is one of the most important commercial crop and major source of guar gum. The clusterbean is affected by various fungal diseases. Among those dry root rot caused by Macrophomina phaseolina (Tassi) Goid., a soil borne, cosmopolitan fungus infecting cluster bean and more than 500 plant species. The first symptom of disease is yellowing of the leaves, dark lesion may be seen on the bark at the ground level, the basal stem & main root may show dry rot symptoms.
