Biological and Chemical Control of Fruit Rot in Greenhouse Sweet Peppers (Capsicum annum L.) Caused by Fusarium subglutinans

R.S. Utkhede and S. Mathur    

Abstract: Experiments were conducted for two years to evaluate biologicals and chemicals for control of internal fruit rot of peppers caused by Fusarium subglutinans under greenhouse conditions. Fusarium subglutinans inoculum was pipetted on flowers of sweet peppers cv. Sympathy one day after applications of chemical and biological treatments. Pepper fruits were assessed for disease incidence and fruit weight sixty days after inoculation of flowers. Pepper fruits in PreStop®, Rovral® , BASF-516 and Quadra-137 treatments were significantly less infected than those observed in inoculated control treatment for 3 inoculations dates in both years. Treatments with Mycostop® and PlantShield® showed significantly less infected fruits compared with the control on 2 inoculations dates in both years. Flowers treated with Rovral® had significantly higher fruit weight compared with the control on 4 inoculation dates in 2003 and for 3 inoculation dates in 2004. Treatments with PreStop® and Quadra-137 produced heavier fruit than the control treatment for 3 inoculation dates in both years. These results suggest that these chemical and biological treatments have the potential to prevent internal fruit rot caused by F. subglutinans on peppers under greenhouse conditions.
