Potato is one type of vegetable that is quite widely developed in Indonesia and has a high economic value. Potato farming has many benefits, among others, as a non-rice food diversification material with high nutritional value and fast producing (cash crop) for farmers. Scab disease is caused by the pathogenic bacteria Streptomyces scabies scabies, which results in yield losses, and the quality of tubers becomes decreased and cannot be sold. One of the controls can be done by using the biological agency Gliocladium sp. This study aimed to determine the effect of the biological agency Gliocladium sp. in suppressing the Intensity of scab disease (Streptomyces scabies Lambert and Loria) on the quality of seed potato (Solanum tuberosum L.). This research was conducted from April to July 2023 at the West Java Province Potato Seed Centre, Sukamanah Village, Pangalengan District, Bandung. The research method used was Randomised Group Design (RAK) consisting of 5 treatments and five replicates with details of the treatments, namely: P0: no treatment, P1: Dazomet 98% 5 g/plant, P2: Gliocladium sp. 25 g/plant P3: Gliocladium sp. 50 g/plant P4: Gliocladium sp. 75 g/plant. The study's results with a dose of Gliocladium sp. 75 g/plant were quite effective in suppressing the Intensity of scab disease attack (Streptomyces scabies Lambert and Loria). However, they did not have a good impact on the quality standards of potato seed quality (Solanum tuberosum L.), with a control effectiveness of 33%.
