![عکس صفحه اول مقاله: Water in oil based PGPR formulation of Pseudomonas fluorescens (FP7) showed enhanced resistance against Colletotrichum musae Water in oil based PGPR formulation of Pseudomonas fluorescens (FP7) showed enhanced resistance against Colletotrichum musae](/preview/png/4505823.png)
• Pseudomonas fluorescens showed FP7 showed maximum reduction of mycelial growth.
• Emulsion of P. fluorescens (FP7) showed higher yield characters.
• Decreased anthracnose disease both under field and post harvest condition.
• Induction defense enzymes were noticed in fruits.
Banana anthracnose incited by Colletotrichum musae is a serious disease in post harvest marketing stage. It occurs in almost all the banana growing countries. In the current study, 5 isolates of C. musae infecting banana cv nendran were collected from various district of Tamil Nadu. C5 isolate collected from Tiruchirappalli showed maximum virulent with (66.60%) PDI. In vitro efficacy of six Pseudomonas fluorescens superior strains were tested for their inhibition on mycelial growth of C. musae. P. fluorescens (FP7) showed significantly higher inhibition of 41.12 per cent over control and with a mean mycelial growth of 52.10 mm. Water in oil emulsion was used in the present research for formulation of P. fluorescens (FP7). The emulsion contained the following ingredients (w/w), sterile deionized water (45.25%), glycerine (4.00%), water-soluble wax ((0.75%), Tween 20 (2.50%), and a mixture of 19.00% soybean oil + 28.50% castor oil. The application of water in oil emulsion formulation significantly increased the yield (68.12 t/ha) compared to control (66.49 t/ha), and also increase in the activity of defense related enzymes viz., phenyl alanine ammonia lyase, peroxidase, polyphenol oxidase, catalase and β-1, 3 glucanase was observed which was followed by talc based formulation of Pf1 and FP7.
