Efficacy of Talaromyces flavus microcapsule in controlling cotton important fungal diseases

Purpose: Evaluation of efficacy Talaromyces flavus microcapsule in controlling cotton important fungal diseases and introducing for using the fields.
 
 Methods: In this research focused on application efficiency evaluation two new formulations T. microcapsules (TF-Co-G-1: Isolate 1 obtained from Gorgan farm) suspension powder forms, which were compared with fungicide Talaromin® farmers' fields. research, farms (Karkandeh Hashemabad) a history infection VW DO selected different regions Golestan province. Each fields an area 1000 m2 was divided into seven equal parts. each part, treatments applied separately, including soil application, as seed impregnation, control. The efficiencies terms studied strengthening growth indicators evaluated by comparing means nine measured traits, three traits disease (the percentage healthy seedlings incidence rate severity VW). To end, mixed analysis variance (ANOVA) first performed MS TAT C software, ANOVA region separately significant effect treatment × location.
 Results conclusion: results showed that among formulations, impregnation 32% 59% respectively most effective increase decrease VW. Therefore, indicate technical knowledge to produce forms can be transferred manufacturing companies carry out commercialization mass production process.
 Originality/value: Production microcapsule.
