Abstract

Cucumis sativam (L.) is creeping vine grown as an off-season vegetable crop under protected poly houses. During survey of major cucumber growing districts of Rajasthan, a new disease “Choanephora fruit rot of cucumber” was first time observed and recorded during in 2019-2020. The survey provided baseline information on the distribution, occurrence and incidence of Choanephora fruit rot in the major cucumber growing area of Rajasthan state. During the survey, discussions were held with the farmers concerned, regarding occurrence, incidence and yield losses due to this disease. Choanephora cucurbitarum is the new emerging pathogen as well as serious threat to cucumber and other vegetables in India. The disease incidence was recorded ranged from 45.61 % to 64.22 %. During the rainy season (July-November), the temperature was 28-30°C with high humidity (70-90%) that favored disease development. During survey typical symptoms of Choanephora fruit rot were observed under polyhouse condi

Conclusion

The present research investigation has opened up new information and given rise to new ideas on Choanephora fruit rot of cucumber. Hence the future lines of work are needed with there is a need to undertake an intensive survey for Choanephora fruit rot disease of cucumber in all agro-climatic zones of Rajasthan and quantify the loss caused by this pathogen. To identify the molecular variability in Choanephora fruit rot pathogen that prevalent in different agro-climatic zone of Rajasthan.
