Uji Lapangan Pengendalian Hama Terpadu Biointensif terhadap Wereng Batang Cokelat dan Hawar Daun Bakteri pada Padi.

Abstract

Padi merupakan komoditas pertanian yang sangat penting. OPT seperti wereng batang cokelat (WBC) dan hawar daun bakteri (HDB) merupakan salah satu kendala produksi padi. Pengelolaan hama terpadu dengan mengutamakan pemanfaatan sumber daya hayati merupakan pendekatan yang diharapkan dapat berkelanjutan dan ramah lingkungan. Penelitian ini bertujuan untuk membandingkan teknologi PHT bio-intensif dengan metode konvensional dalam pengelolaan WBC dan HDB pada padi serta pengaruhnya terhadap hasil gabah kering panen panen (GKP) di Kecamatan Sampang, Kabupaten Cilacap. Variabel pengamatan berupa kepadatan populasi WBC dan intensitas penyakit HDB diamati setiap minggu, sedangkan bobot gabah kering panen diamati pada akhir percobaan. Hasil penelitian menunjukkan bahwa teknologi PHT bio-intensif relatif mampu menekan perkembangan WBC dan HDB pada padi dibandingkan dengan metode konvensional. Hasil bobot GKP PHT bio-intensif cenderung lebih tinggi dari metode konvensional, namun tidak berbeda signifikan secara statistik. Diantara perlakuan yang diuji, perlakuan BIO 2 menunjukkan keuntungan tertinggi dibandingkan perlakuan lainnya.

Rice is a very important agricultural commodity. Plant pests such as the brown planthopper (BPH) and bacterial leaf blight (BLB) are one of rice productions constraints. Integrated pest management by prioritizing the use of biological resources is an approach which is expected to be sustainable and friendly to the environment. This study aims to compare bio-intensive IPM technology with conventional methods in managing BPH and BLB in rice and its effect on harvested dry grain yields in Sampang District, Cilacap Regency. The variables were weekly observation of BPH population density and BLB disease intensity, and harvested dry grain weight at the end of experiment. The result showed that bio-intensive IPM technology was relatively able to suppress the development of rice BPH and BLB comparing to conventional method. The production of harvested dry grain in the bio-intensive IPM treatment tended to be higher than the conventional treatment although not statistically different. Among treatments tested, BIO 2 treatment showed highest profit over other treatments.
