Efikasi in Vitro Pelet Erwinia sp BST4 dan Trichoderma harzianum Blt1 Dalam Menekan Infeksi Phytophthora capsici Pada Lada

Karden Mulya, Rita Noveriza, Dyah Manohara

Abstract


Foot rot disease pf peppercaused by Phyrophthora capsici is a limiting factor in Pepper cultivation since initial symptom of the Disease was difficult to be observed, it was Commonly fail on application curative Treatment. This study was aimed to test the Ability of a mixtuse biocontroll agents Formulated as pellet. Antagonistic activity was Tested on dual culture. Bacterial antagonists Were identified based on physiological and Biochemical characters. Pellet formulation for Trichodema harzianum Blrl was used as basic Formulation Results showed that Erwinia sp. BST4 Viable in pellet formulation without Affected the growth of T. Harzianum Bltl.In in Viva test. At one month after application of Pellet. T. Harzianum pellet or Erwina sp. At the Rate of 10 g/200 g inoculum inhibited the Percentage of colonization of P. Capsici will Decrease when T. Harzianum was mixed with Erwina sp. In the same pellet.


Keywords
