Cassava (Manihot esculenta Crantz. or Manihot utilissima Pohl.) are annual tropical and subtropical shrubs from the Euphorbiaceae tribe. Bulbs is widely known as a staple food producing carbohydrates and leaves as vegetables. Indonesia is the second largest country producing Cassava after Nigeria with an average of five years of total supply of 9.67 million tons, or 10.61% of the total supply of world cassava. Central Cassava land in Indonesia is controlled by Lampung province with production in 2013 reaching 8.33 million tons. This situation makes Lampung a supplier of one third of the national Cassava production from national production of 23.92 million tons. However, there are still many production constraints in Cassava cultivation, including Fusarium wilt, caused by Fusarium oxysporum (Fo). The use of Cassava cultivars that are resistant to the disease is expected to be an important disease control alternative. Planlet Cassava has been selected in Murashige and Skoog (MS) medium with the addition of fusaric acid (AF) concentration of 0 ppm (control), 20 ppm, 40 ppm, 60 ppm, and 80 ppm in vitro. Stages of activities carried out include: (1) Testing of Cassava resistance to Fo in vitro, and (2) Analysis of total phenol. The purpose of this study 1) to test the resistance of Cassava plantlets resistant to Fo in vitro; 2) knowing the specific expression character of Fo-resistant Cassava plantlet which is total phenol. The results showed that: 1) in vitro, the 80 ppm AF treatment was able to mitigate the resistance of the Cassava plantlets best, to reduce disease intensity by up to 25% and increase the criteria of being resistant. 2) the higher the concentration of AF, the higher the total phenol content of the Cassava plantlets increases Fo.
