Efficacy of different concentrations of microcapsules containing Talaromyces flavus with two formulations of powder and suspension in controlling Fusarium wilt disease of tomato

The efficiency of powder microcapsules and suspension microcapsules of Talaromyces flavus with concentrations of 106 × 2, 106 × 4, 106 × 6, 106 × 8 and 107 colony forming units per gram of formulation in soil addition method and a concentration of 107 colony forming units per gram of formulation in seed impregnation method was compared with registered fungicide Talaromin in two methods of seed impregnation and addition to soil to control Fusarium wilt disease of tomatoes. The results showed that the most effective treatments were related to the different concentrations of suspension microcapsules by soil addition method and powder microcapsules by seed coating method and the highest concentration (107 colony forming units per gram) in adding to soil method reduced significantly 83- 96% the severity of the disease compared to the infected control.
