Abstract

The study of preference dan attack level of golden apple snail (Pomaceae canaliculata Lamarck) on several rice varieties was carried out in farmers' paddy fields at Limau Manis, Pauh District, Padang, West Sumatera. The aim of this study was to obtain golden apple snail preferences and its attack level on several rice varieties. The experiments used a Randomized Block Design (RBD) with 8 treatments and 3 blocks. The treatments were several varieties commonly grown in West Sumatera, namely: Cisokan, IR 42, Anak Daro, IR 66, Batang Piaman, Ceredek Merah, Kuriek Kusuik, and Junjuang. The parameters observed were the preference, percentage and intensity of golden apple snail attacks on rice, and rice yield. The results showed that golden apple snail liked all rice varieties, but different varieties affected the preference and attack level. The three most preferred rice varieties by golden apple snail were IR 66, IR 42 and Anak Daro. Meanwhile the three least preferred rice varieties were Kuriek Kusuik, Batang Piaman and Junjuang with a low attack level and a high of yield.

Abstract

The leaves of some plants have been proved to suppress the development of plant diseases caused by pathogens. The study aimed to determine the water decoction of leaves to suppress the growth of S. rolfsii caused stem rot on peanuts in vitro. The study was conducted in the Laboratory of Phytopathology Departement of Plant Pest and Disease Faculty of Agriculture, Andalas University, from May-July 2015. The experimental design was a Randomized Complete Design (RCD) with seven treatments and six replications. The treatments were control, water decoction of Annona squamosa, Impatiens balsamina, Eclipta alba, Cymbopogon citratus and Tithonia diversifolia with concentration of 0,5% and fungicide with tebukonazol active ingredient at a concentration of 0,1%. Variables observed were macroscopic fungal culture, colony area, wet and dry weight of colonies. Data were analyzed by using ANOVA and DNMRT at a 5% of significance level.. The results showed that all water decoctions of plant leaves were able to suppress the growth of S. rolfsii. The most active of the water decoction was from T. diversifolia with suppression to colony area reached 77,32%, and wet and dry weight were 77,24% and 84,66%, respectively.
