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.
