Abstract

Trichoderma harzianum as a potential biological agent and are widely used to control diseases in various agricultural crops and plantations. This research goal of getting the best growth of Trichoderma harzianum on molasses-based liquid medium. The treatments tested was added 0.05%, 0.1% and 1% liquid pure culture of Trichoderma harzianum each in 500 ml of sterile liquid medium containing 5% molasses (v/v) and 5% commercial yeast (b / v), and incubated for five days. The results showed that Trichoderma harzianum growth with the highest number of spores occur if the molasses-based liquid medium supplemented with 1% Trichoderma harzianum.

Abstract

Low quality of banana fruits due to anthracnose caused  by Colletotrichum musae fungi could be overcome by introducing anthracnose-resistent varieties. The research’s objective was to find out pathogenecity of C. musae on six local banana varieties namely Dewaka, Ambon Kuning, Abu-abu, Raja,  Empat Puluh Hari and Nona. A laboratory experiment was carried out by using completely randomized block design with six replicates. The result showed that the pathogenicity of C. musae on  six varieties of banana fruits was differ. Average incubation period of fungi and damage level of banana fruits were 3.5 days and 32.53% respectively whereas average rate of infection of C.musae was 0.115 units/day. This experiment suggested that banana var. Abu-abu was resistance to anhtracnose while banana var. Raja, Ambon Kuning  as well as Dewaka were susceptible to anthracnose. Banana var. Empat Puluh hari and Nona were classified in moderately resistance to anthracnose.
