Four districts Fazilka, Hoshiarpur, Shri Muktsar Sahib, and Bathinda were the sites of this study. These regions were chosen on purpose since they had the highest number of Kinnow growers and the most area under Kinnow production. The responsible Horticulture Development Officers of the Horticulture Department provided a combined list of Kinnow growers, which included 1745 farmers from four districts. Using the probability proportional to size sampling method, 200 Kinnow growers were chosen from the four districts. From Fazilka, Hoshiarpur, Shri Muktsar Sahib, and Bathinda, respectively, 92, 74, 18, and 16 Kinnow growers were chosen. Major findings of the study were, Sodium Hypochlorite was the most cost-efficient Phytophthora management practice among all the other management practices with an average price of 500 Rs. per acre.

In case of chemical methods around 46.4 per cent of the respondents adopted Ridomil Gold 68 WP for management of Phytophthora disease. In case of cultural methods 84 per cent of the respondents adopted disease free nursery planting material for management of Phytophthora disease followed by 67.5 per cent of the respondents followed Bud union above ground level for management of Phytophthora disease.
