Efektivitas Seed treatment dengan Fungisida dan Agens Hayati dalam Pengendalian Penyakit Rebah Kecambah (Sclerotium rolfsii Sacc.) pada Kedelai

Abstract

Soybean (Glycine max L. Merril) is one of the commodities for meeting the vegetable protein needs of the Indonesian people. In soybean cultivation, there is interference from plant pests, one of which is Sclerotium rolfsii. S. rolfsii infection is divided into two phases: pre-emergence damping off and post-emergence damping off. S. rolfsii control can be done using synthetic fungicides such as Mancozeb, and biological agents such as Trichoderma sp. and Bacillus sp. S. rolfsii can survive in the soil and form sclerotia, making it classified as a soilborne pathogen. Control of S. rolfsii disease can be done by seed treatment method using immersion of fungicides Mancozeb, biological agents Trichoderma sp., and Bacillus sp. Mancozeb fungicide is able to suppress the growth of S. rolfsii in vitro by 22.22%, Trichoderma sp. by 86.86%, and Bacillus sp. by 5.00%. Soybean seed treatment using Mancozeb fungicide has an effectiveness value of 16.93%, Trichoderma sp. 45.24%, and Bacillus sp. -6.10% in controlling damping off in vivo.
