Identification and Controlling Verticillium Wilt Infecting Parkia roxburghii Seedlings in Manipur India

Rajesh Kumar, Ashwani Tapwal and Rajib Kumar Borah

Abstract:
A study was conducted to control Verticillium wilt disease of Parkia roxburghii. It was isolated from the infected roots of the seedlings collected from Forest Nursery of Chandel district, Manipur, India. Four fungicides viz. Bavistin 50% WP, Dithane M-45, Dithane Z-78 and Fytolan 50% WP were screened against the pathogen at different concentrations using poison food technique in vitro and then in field-conditions using soil drenching technique. The results revealed that Bavistin 50% WP was most effective at 75 ppm with 100% growth inhibition followed by Dithane M-45, Dithane Z-78 and minimum efficacy was observed by Fytolan 50% WP with 31.27% growth inhibition in laboratory conditions. All selected fungicides were evaluated against pathogen in field conditions at 0.1 and 0.2% concentrations. Bavistin 50% WP was reported to be the most effective at 0.2% concentration. Thus, the present study recommends soil drenching with Bavistin 50% WP at a minimal concentration of 0.2% for management of the disease.
