PENGENDALIAN PENYAKIT KARAT TUMOR (Uromycladium tepperianum (Sacc.) Mc. Alpin) PADA SENGON (Falcataria mollucana (Miq.) Barneby & J.W. Grimes) DI PANJALU KABUPATEN CIAMIS JAWA BARAT

Abstract

Sengon (Falcataria moluccana (Miq.) Barneby & JW Grimes) is one of the current tree developed oncommercial scale, however, the existence of disease caused by a gall rust (Uromycladium tepperianum(Sacc.) Mc. Alpin) fungi is quite serious constraint for its development. Therefore, it needs to performeddisease control to avoid a huge loss. The aim of the research was to know effectiveness of sulphur, lime andsalt to control gall rust disease in Panjalu, Ciamis District, West Java. The experiment consists of sixtreatments and each treatment used ten trees. Treatments were P0= control, P1= sulphur, P2= lime, P3=lime and sulphur mixture (1:1) (w/w), P4= sulphur and salt mixture (10:1) (w/w), P5= lime and saltmixture (10:1) (w/w), and P6= sulphur, lime and salt mixture (10:10:1) (w/w/w). The results showedtreatment P4 and P5 had the highest inhibiting percentage of gall rust growth and total amount of gall rustsuppression. However, this value statistically not different from the treatment of P2 and P6
