Integrated disease management module for management of downy mildew of cucumber

In the present study, status of downy mildew of cucumber was ascertained in Jammu division of Jammu & Kashmir (India) and the disease incidence and severity was recorded up to 70.29 per cent and 56.01 per cent respectively at 80 days after transplanting. Among the twenty two cucumber germplasm evaluated for resistance to downy mildew, eleven were observed to be moderately susceptible and another eleven susceptible. However, none fell in the category of resistant, moderately resistant or highly susceptible. Among the fungicides tested with varying number of sprays, metalaxyl + mancozeb (five sprays) was most effective and reduced the disease intensity up to 94.23 per cent over control. Plant extract of Allium sativum was most effective causing disease reduction of 49.88 per cent. An extra dose of potash reduced the disease by 30.93 per cent. An integration of these measures can be utilized for developing an integrated disease management module for management of downy mildew of cucumber.
