Sengon gall rust (Uromycladium falcatarium)

Sengon gall rust ( Uromycladium falcatarium ) is a species of fungi in Raveneliaceae, grows on molucca albizia ( Falcataria moluccana ) as the host plant, the symptoms vary widely and sometimes are not obvious, the host stem shows brownish lumps to kill slowly. U. falcatarium infects host shoots at the age of 2-3 weeks which causes the leaves to curl, leg, do not develop normally and fall off easily. At 6 weeks of age, symptoms appear on curved and stiff stems and shoots. At the age of 3 months or more the tumor begins to enlarge. Symptoms begin with tumefaction on the leaves, branches and stems. Subsequent development creates a lot of brownish green bumps which then become small rashes on part of the stem or the whole.
