Survey on the incidence of Fusarium wilt of tomato incited by Fusarium oxysporum f. sp. lycopersici (FOL) in major tomato growing areas of Khordha district, Odisha, India

Abstract

One of the main issues with tomato production is fusarium wilt, often known as vascular wilt or Fusarium oxysporum f. sp. lycopersici. In order to determine the disease incidence of fusarium wilt in several tomatogrowing regions of the Khordha district, Odisha, in the years 2021–22 and 2022–23, a survey was conducted. A total of ten villages (one village from each block) were visited, and each village’s five fields were examined. This was done by counting the number of sick or infected plants in each field’s randomly chosen five-byfive-meter tomato field. Pichukuli village (25.70%), Jankia village (23.69%), and Jagannathpur village (22.59%) had the highest per cent disease incidence. Nachuni village (16.72%) and Siko (17.28%) had the lowest per cent disease incidence, respectively. The survey’s findings showed that there was a disease incidence that was causing output and crop losses for tomatoes.
