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.Keywords

Cabbage (Brassica oleracea L. var. capitata) is second important vegetable crop of Cole group. A rich source of vitamin A, B and C it also contains minerals. The cabbage cultivars are under a great threat for profitable cultivation due to the attack of several abiotic and biotic factors viz., Fungi, Bacteria, Virus, Nematode etc. The experiment on integrated disease management of Cabbage leaf blight disease under field conditions revealed that out of 12 treatments using fungicides and bio-agent formulations was conducted during 2012-13 and 2013-14. The mean of analysis of two years data indicate that the minimum disease intensity 4.56 per cent was recorded in three foliar sprays of Acrobat @ (0.1%) + Mancozeb@ (0.2%) which also gave maximum yield 408.02 q/ha. Second best treatment was three foliar sprays of Ridomil MZ-72@ (0.2%) which gave 4.60 per cent disease intensity and 373.65 q/ha heads yield.Keywords

Cucumber (Cucumis sativus L.) is an important cucurbitaceous vegetable crop. Cucumber crop is attacked by various plant diseases, among them Powdery Mildew of cucumber caused by Erysiphe cichoracearum is an important disease which effect a large area of the cucumber crop. An experiment was laid down at Vegetable Research Farm, Kalyanpur, Kanpur for disease management by chemicals and observations on disease intensity and yield was recorded in consecutive years (2011-12 and 2012-13). It is evident that minimum disease intensity (6.85% and 7.35%), maximum edible fruit yield of cucumber (221.36 and 216.19 q/ha) and maximum C:B ratio (1:2.90) were recorded in treatment (T5) three foliar sprays of Bayliton (0.2%) at 10-12 days intervals from initiation of the disease followed by treatment (T1) three foliar sprays of Tridemorph (calexin 0.1%), which gave (10.15 and 8.65%) disease intensity, (204.12 and 209.62q/ha) edible fruit yield and C:B ratio (1:2.45).Keywords

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%).Keywords

Among the ten isolates of Sclerotium rolfsii, collected from major chilli growing areas of Uttar Pradesh found that the pathogenic variability of the pre germination disease incidence was highest (21.20%) in isolate of district Fatehpur and was lowest (9.5%) in Raibarelly isolates. The cultural variability on the radial growth of fungus and sclerotial production indicated that the radial growth of fungus was maximum in the case of SR1 (83.0 mm) isolate, followed by SR9 (82.00 mm) isolate which were statistically at par with each other. The colony characters was excellent, fluffy in SR1, SR2, SR3, SR4, SR8, SR9 and SR10 isolates and compact in isolates of SR5, SR6 and SR7. In vitro studies revealed that the fungicides like Taqat, Hexaconazole, Propiconazole, Tricyclazole, Copper-oxychloride and Vitavax were most effective against the pathogen. The effect of fungicides as seed treatment revealed Taqat and Hexaconazole were found most effective in seed germination (92.8 and 87.5%), respectively and minimum in disease incidence (5.3 and 7.1%), respectively.Keywords
