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.
