Formulasi Pelet Berbahan Aktif Trichoderma sp. untuk Pengendalian Penyakit Rebah Kecambah (Pythium sp.) pada Tanaman Mentimun

Abstract

Cucumber (Cucumis sativus Linn. ) is an important agricultural comodity in Indonesia, but the production rate of it still low. One of the factors that causes the low productivity is plant diseases. Damping-off disease often causes the damage of cucumber plant, early stage of cucumber plant growth. It is caused by Phytium sp, a fungus that lives in the soil as soilborne disease. The controlling effort of this disease have been done, for example by using Trichoderma sp. as bio-agent, but the utilization of the bio-agent still not practical so it is difficult to be applied in field. The utilization of Trichoderma sp as a pallet formulation is more effective to be implemented because of the small size and easily moved. The purpose of this research is to produce the pellet formulation with active material of Trichoderma sp. with high nutritious, cheap and easy carrier. This research uses two tests, invitro and invivo. The invitro test uses six different pellet formulations, DAT, UAT, TAT, PAT, DDS and ATS. The best formulation in invitro test byare UAT and DDS because Trichoderma sp can grow very well in these pellet formulation and the raw material of them are cheap and easily obtained. The DDS and UAT can suppress the attack of pathogenic fungus, Pythium sp. on the test with invivo
