چکیده

در این تحقیق، کارآیی فرمولاسیون‌های میکروکپسول پودر و میکروکپسول سوسپانسیون Talaromyces flavus با غلظت‌های 106×2  ،106×4، 106×6، 106×8 و 107 واحد پرگنه ساز در هر گرم فرمولاسیون با روش افزودن به خاک وغلظت 107 واحد پرگنه ساز در هر گرم فرمولاسیون با روش آغشته‌سازی بذر با قارچ کش ثبت شده تالارومین در دو روش آغشته‌سازی بذر برای کنترل بیماری پژمردگی فوزاریومی گوجه‌فرنگی مقایسه شد. نتایج نشان داد که مؤثرترین تیمارها مربوط به‌غلظت‌های مخلف میکروکپسول سوسپانسیون با روش افزودن به خاک و میکروکپسول پودر با روش آغشته‌سازی بذر و بیش‌ترین غلظت آن (107 واحد پرگنه ساز در هر گرم) در روش افزودن به خاک بوده که از 83 تا 96 درصد موجب کاهش معنی‌دار درصد شدت بیماری در مقایسه با شاهد آلوده شد.

چکیده [English]

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.
