Abstract

Cowpea (Vigna unguiculata L.) is the most important legume and vegetable crop grown in India. Most of the promising cowpea cultivars are under a great threat for profitable cultivation due to the attack of several abiotic and biotic factors viz., Fungi, bacteria, virus and nematodes. The major losses of cowpea are covered by fungi, in which anthracnose caused by Colletotrichum lindemuthianum is more important. The experiment on integrated disease management of cowpea anthracnose disease under field conditions with twelve treatments and three replications using fungicides and bio-agent formulations was conducted during 2013-14 and 2014-15. The mean of analysis of two years data revealed that the three foliar sprays of Thiophenate methyl (0.1%) at 10 days interval from initiation of the disease gave average minimum disease intensity (10.63%) and maximum edible pod yield (11.34 q/ha). This was followed by foliar sprays of Difenaconazole (0.06%) which gave average 16.94 per cent disease intensity and pod yield 9.99 q/ha. From the table it is cleared that the fungicides belonging to Trizole groups are more effective.

Abstract

Okra (Abelmoschus esculentus L. Moench) earlier designated as Hibiscus esculentus (L.) is one of the most important vegetable crops extensively cultivated in Kharif and Zaid seasons in India. Present investigation was carried out during 2011 to 2013. The radial growth of the fungus in various treatments was measured and the average of diameter of the colony was noted. However, among the 13 fungicides, only three fungicides viz., Tebuconazole, Propiconazole and Bavistin 100 per cent radial growth of the fungus and proved to be the most effective as they have inhibited the fungus growth. In field conditions maximum seed germination (98.33%), minimum disease incidence (0.17%) and maximum fruit yield 145.16 q/ha was recorded in treatment three foliar of the Tebuconazole (0.1%).

Abstract

Chilli (Capsicum annuum L.) is one of the most important vegetable among solanacious group like potato, tomato etc. Most of the promising chilli cultivars grown in nursery are under a great threat for profitable cultivation due to the attack of several abiotic and biotic factors viz., fungi, bacteria, virus and nematodes. The major losses of chilli in nursery stage are covered by fungi, in which damping-off and wilt disease of chilli caused by Fusarium oxysporum f.sp. capiscum is more important diseases. For the management of damping-off and wilt of chilli to produce healthy seedlings of Chilli free from damping-off and wilt disease, there was a need to develop new technology for better management in nursery stage an experiment was conducted at different places/first at nursery and other in main field of Vegetable Research Farm for two years with ten treatments and three replications. The treatment of maximum seed germination (84.34%), ischolar_main length (21.97cm), shoot length (16.19cm), viguor-index (3217.46), minimum damping-off disease incidence (6.49%), wilt disease incidence found in main field (0.00%) and maximum red ripe fruit yield 30.19 q/ha was recorded in (T₉) Fenamidone + mancozeb (0.25%) drenching, next best effective treatment were (T₆a) seed treatment with (Carbendazim + mancozeb) 1.5g/kg seed + drenching of nursery (0.1%) and (T₇) use of Pencycuron 1ml/lit. in drenching which were statistically at par in case of seed germination, disease intensity and red ripe fruit.

Keywords
