Abstract
Bacterial leaf blight can cause rice loss between 15-80%. Biorational pesticides can be an alternative to controlling the disease. Bacillus firmus, Burkholderia sp, and Serratia marcescens against bacterial leaf blight on rice plants in the field. The study was conducted in Maret-Juni 2014 in the land of the Independent Farmers Group, Cipeuyeum Village, Haurwangi District, Cianjur Regency, West Java. The design uses a randomized complete block design (RCBD) with 6 treatments and 4 replications. The treatments consist of: 1) Mekongga + biorational, 2) Inpari 14 + biorational, 3) Sintanur + biorasional, 4) Mekongga + without biorational, 5) Inpari 14 + without biorational, and 6) Sintanur + without biorational. The results of the study showed that the application of biorational pesticides can reduce the intensity of bacterial leaf blight disease. Sintanur varieties with the application of biorational pesticides produce higher and higher R / C ratios of 6.81 tons ha-1 and 2.79.

Summary
Serangan hama dan penyakit merupakan salah satu faktor pembatas dalam budidaya padi karena menyebabkan kerusakan pada tanaman. Sampai saat ini berbagai upaya telah dilakukan untuk mengendalikan penyakit HDB yaitu dengan menggunakan bahan kimia atau pestisida sintetik yang berpotensi menyebabkan resistensi terhadap bakteri, menimbulkan residu, dan pencemaran lingkungan. Menurut Wahyudi dkk., (2011) upaya pengendalian HDB terkendala oleh kemampuan patogen membentuk strain baru yang lebih virulen lebih cepat sedangkan penggunaan pestisida kimia dapat menyebabkan gangguan pada kesehatan manusia dan lingkungan. Merupakan salah satu jenis mikroba yang berpotensi dalam menghambat pertumbuhan bakteri patogen tanaman padi X. oryzae pv. Penelitian Agustiansyah dkk., (2013) menunjukkan bahwa B. subtilis mempunyai kemampuan menghambat pertumbuhan X. oryzae pv. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pestisida biorasional yang mengandung Bacillus firmus, Burkholderia sp., dan Serratia marcescens terhadap penyakit hawar daun bakteri pada tanaman padi
