Potensi ekstrak kasar metabolit sekunder yang dihasilkan Trichoderma asperellum dan Pseudomonas fluorescens untuk pengendalian antraknosa pada buah kakao

Cocoa pod anthracnose is an important disease of cocoa and can reduce yields. Many attempts have been made to control rot on pods but not successful yet. This study aimed examine the potency secondary metabolite crude extracts produced by Trichoderma asperellum Pseudomonas fluorescens solely or in combination controlling field at Silo Bonto Village, Asahan Regency, North Sumatera Province. The was prepared form conidia T. P. cells. A randomized block design used assessed four treatments i.e. + fluorescens, asperellum, control, which repeated six times. observation parameters were percentage healthy diseased (anthracnose fruit rot). results showed that reduced number fruits 94.71, 89.09, 92.09% compared respectively. increasing application 52.68, 54.20, 54.18%,
