| Abstrak The low productivity of coffee (Coffea) in Indonesia, among others, is caused by the high disturbance of leaf rust disease (Hemileia Vastatrix) as a result of not implementing the correct technical culture practices, including the control of leaf rust disease (Hemileia Vastatrix). This study aims to determine the intensity of leaf rust attack. (Hemileia Vastatrix) on coffee varieties (Coffea) Usda, Typika, Lini-S and Katura yellow developed with an Agroforestry Pattern with an organic system. This research was conducted for two months, from October to December 2019, which was located in the plantation area owned by PT. Sulotco Jaya Abadi in Bolokan Village, Bittuang District, Makale Regency, South Sulawesi. This study consisted of 4 treatments and five replications so that there were a total of 20 experimental units. The treatments consisted of four varieties, namely, typika variety, Usda variety, chess yellow variety and linear S variety. The results showed the intensity of leaf rust disease (Hemileia vastatrix) in coffee plants (Coffea) Typika variety was 3.20%, Usda variety. amounted to 3.17%, Catura yellow variety was 1.20% and Lini-S was 1.65%, Typika variety is the variety that has the highest attack intensity and Catura yellow variety is the variety that has the lowest intensity on this protecti Keywords: Typika variety is the variety that has the highest attack intensity. |
