Online published on 12 April, 2021. Abstract Among the different biotic stresses, gummosis/foot rot caused by Phytophthora nicotianae is the most severe and economically important disease in major citrus-growing areas of Punjab. It is increasingly becoming the major limiting factor in the successful cultivation of citrus in Hoshiarpur, Faridkot, Fazilka, Bathinda and Muktsar districts. This disease commonly occurs seriously during July-October following periods of high rainfall with warm temperatures and reduces the profitable life expectancy of trees. The research trials were conducted to manage citrus gummosis using sodium hypochlorite during 2015 to 2017 and this technology was also demonstrated at farmers’ orchards, Fazilka and Faridkot districts during 2017. Sodium hypochlorite @ 50 ml/10 litres of water/plant was found very effective in providing per cent recovery from trunk lesion and in reducing propagule density of the pathogen.
