PENYAKIT LAYU SCLEROTIUM PADA TANAMAN SAMBILOTO

Abstract


Sclerotium sp. is the causal agent of wilt disease on Andrographis paniculata Nees. The infection occurs in rainy season and causes the plant wilting. Sclerotia were found abundantly on dead tissues of the plant. Observation on the biology, inocculation, and biological control (in vitro) of Sclerotium sp. was done at the Research Institute for Spices and Medicinal Plants. The plant wilted 7 days after. inocculation using mycelial and died 4 days afterwards. Clove powder containing 200 ppm eugenol could inhibit the growth and development of fungus mycelial, while the germination of sclerotia was inhibited at a concentration of 3 ppm eugenol.
