Aplikasi Ekstrak Kulit Lidah Buaya (Aloe vera L.) untuk Mengendalikan Cendawan Terbawa Benih Padi

Abstract

Rice plant (Oryza sativa L.) is one of the most widely grown food crops in Indonesia, but the average productivity of rice in Indonesia is still low. One of the causes of low rice production is the attack by plant pest organisms. There is no research on aloe vera peel extract as an antifungal against fungus growth, so it is necessary to investigate whether aloe vera peel extract is also efficacious as an antifungal against rice seed-borne fungi.This study aims to determine the application of aloe vera peel extract and obtain a good concentration of aloe vera peel extract to control pathogenic fungi carried by rice seeds. Isolation of the fungus carried by rice seeds was carried out by the Blotter test method and the pathogenicity test by the Bioassay method. Then made several extract concentrations, namely 0 ppm, 250 ppm, 500 ppm, 750 ppm and 1000 ppm. The test results showed that aloe vera peel extract was able to suppress the growth of rice seed-borne fungi, but it was phytotoxic and the best concentration to be applied to control rice seed-borne fungi was a concentration of 250 ppm.
