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).

This study, with two antagonists, two fungicides (alone and combinations) against Fusarium tomato wilt. Pot culture studies found that Average reduction of F. oxysporum f. sp. lycopersici recorded with the test fungicides and bioagent ranged from 25.81% to 72.21%, as against 00.00% in untreated control.

Turmeric (Curcuma longa L) rhizome rot caused by Pythium aphanidermatum was one of the divesting disease and causes accountable losses. All fungicides, bioagents, botanicals and soil amendments (alone and in combination) tested in vitro for management of turmeric rhizome rot was found effective against P. aphanidermatum.

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.

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.

Twelve fungicides including systemic and non-systemic, five bioagents and eight plant extracts were evaluated in vitro against Exserohilum turcicum, the causal agent of Turcicum leaf blight of maize. All the test fungicides, bioagents and plant extracts showed fungistatic action and significantly inhibited mycelial growth of the test pathogen over untreated control.

Among the diseases of safflower; dry root rot disease caused by Macrophomina phaseolina (Tassi.) Goid is one of the most destructive and wide spread diseases of Safflower (Carthamous tinctorius L.) causing accountable losses of about 25-60 per cent. A total of ten fungicides namely: Captan, Iprodine, Copper Oxychloride, Thiram Mancozeb, Difenconazole, Propiconazole, Cymoxanil8%+Mancozeb 64%, Carbandazim, & Metalaxyl 8% + Mancozeb 64% were evaluated in vitro against Macrophomina phaseolina.

Soybean [Glycine max (L.) Merrill.] is an important oilseed crop. Colletotrichum truncatum, the incitant of anthracnose/ pod blight in soybean is one of the most destructive pathogens. Eight fungicides (@ 500, 1000, 1500, 2000 and 2500ppm each), 10 botanicals@ 10% and four bioagents were evaluated in vitro against C. truncatum, using PDA as basal medium. The results revealed that all the fungicides, botanicals and bioagents tested were found fungistatic and significantly inhibited the mycelial growth of the test pathogen over untreated control.

A field experiment was conducted at the research plot of the Department of Plant Pathology, SHIATS, Allahabad, U.P. during the Rabi season of 2013-14 to evaluate selected bioagents, plant extracts and fungicides for the management of Alternaria blight of Indian mustard (Brassica juncea L.) by applying foliar sprays of certain fungicides plant extract and bio-agents. Per cent disease intensity on leaves at 75 DAS, per cent Alternaria pod blight at 90 DAS, test weight (g/1000 seeds) and yield (q/ha) were recorded.

To manage the disease an investigation at the Department of Plant Pathology, SHIATS-DU, Allahabad was carried out to evaluate the effect of bio-agents viz. Trichoderma viride @ 2%, Pseudomonas fluorescens @ 2%, T. harzianum @ 2%, botanical viz. neem leaf extract @ 5%, neem oil @ 5% and fungicide viz. carbendazim @ 0.2% against R. solani under invitro condition by dual culture and poisoned food technique. All the bioagents and botanical were evaluated singly. All the treatments significantly inhibited the mycelial growth of R. solani as compared to untreated check.

Foot rot of tomato is an important disease which causes severe loss in tomato production. The present study was carried out to evaluate five bioagents and six fungicides against Sclerotium rolfsii. Among the five antagonists tested the maximum inhibition was observed in Trichoderma virens (67%) and contrarily, no inhibition was observed in Bacillus subtilis. Six fungicides viz., carbendazim, captan, tebuconozole, copper oxychloride, hexaconozole and Tebuconazole +Trifloxytrobin at different concentrations (50, 100, 150, 200, 250 and 500 ppm), were tested.
