Abstract

Brazil is the origin of an area of rubber plants (Hevea brassiliensis) which is able to provide one source of non-oil and gas foreign exchange. In 2012, Indonesia's rubber plantation area was 378,423.3 ha, the total production was 287,653.11 tons. If on smallholder plantations that is 0.76 tons per ha. With this the need to increase good productivity by using good technology to rejuvenate old rubber with superior clones, Indonesia has a relatively low rubber productivity. The country's average productivity is 1260 kg per ha per year in rubber plantations compared to rubber productivity in private plantations which is 1050 kg per ha per year. And only 590 kg per ha per year in community plantations. Low productivity due to many diseases. The purpose of this study was to suppress the development of Pestalotiopsis sp. in Rubber Plants using Biopesticides with active ingredients Psendomonas Fluorescens P60 and Trichoderma harzianum Ginger Isolates T10. This study used a randomized block design (RBD) method, with 6 treatments and 4 replications, each treatment used 2 plants, so that 48 experimental plants were obtained, the study was conducted 6 times / 2 weeks in 3 months. The benefits of this research are expected to reduce the development of Pestalotiopsis sp. in rubber plants that are infected with Deciduous leaf disease Pestalotiopsis sp. Biologically environmentally friendly Key words: Rubber plant, Pestalotiopsis sp. Rubber disease, GT1 clone. Psendomonas fluorescens, Trichoderma harzanium,
