Abstract

Integrated Pesl Control Research of // antonii on cashew was studied out in Wonogiri, Central Java from May lo December 2000. Ihe objective of the study was lo obtain Ihe efective eonlrol method Spill plot design was used. Ihe main plots were intercropping system of cashew with (a) niunghcan and (b) mixed of cassava, peanut and maize, The subplots were treatments of (a) benomyl without B bassiana. (b) R bassiana without benomyl, and (c) eonlrol The concentation of benomyl used were 2 g per liter, while for II. bassiana 11) g per liter containing I. I x 10* conidias. Treatments were applied on Ihe beginning of October 2000, and observations were done twice in one month. The area needed for all plots were 24 000 m1 (4 replications). Hie asscsments consisted of (a) number of //. antonii eggs, nymphs and its natural enemies, (b) number of flowers and shoots attacked, and (c) cashew nut per tree. The result showed thai there was interaction between the Iwo factor tested. Mix-cropping with R bassiana reduced //. antonii population on cashew and increased productivity from 3.85 kg lo 5.33 kg per tree. These treatments were therefore recommended for controlling the pest.

Abstract

Wereng batang cokelat adalah hama utama pada tanaman padi yang dapat menyebabkan gagal panen. Pengendalian wereng batang cokelat (WBC) masih ditekankan pada penggunaan varietas tahan dan insektisida. Perlu upaya alternatif menggunakan cara pengendalian yang lebih ramah lingkungan, diantaranya agens hayati, seperti cendawan entomopatogen Beauveria bassiana dan pupuk organik cair (POC). Penelitian bertujuan untuk mengetahui keefektifan campuran cendawan entomopatogen B. bassiana dan POC terhadap hama WBC. Penelitian dilakukan di Laboratorium dan Rumah Kasa Balai Penelitian Tanaman Rempah dan Obat (Balittro) Bogor sejak Juli sampai September 2015. Penelitian terdiri atas dua kegiatan. Kegiatan pertama adalah percobaan kompatibilitas yang dirancang secara Acak Lengkap (RAL), empat perlakuan dan diulang lima kali. Perlakuan yang diuji adalah tiga  konsentrasi larutan POC (5, 10 dan 20 ml.l-1), dan air sebagai kontrol. Pengujian dilakukan terhadap pertumbuhan cendawan B. bassiana pada medium yang mengandung POC. Kegiatan kedua adalah pengujian keefektifan cendawan B bassiana untuk mengontrol WBC di rumah kasa, dirancang menggunakan RAL, lima perlakuan dan diulang lima kali. Perlakuan yang diuji adalah B. bassiana (kerapatan spora 108 ml-1); B. bassiana + POC (10 ml.l-1); minyak seraiwangi (5 ml.l-1) dan minyak cengkeh (5 ml.l-1) sebagai pembanding, serta air (kontrol). Aplikasi dilakukan dengan cara menyemprotkan larutan perlakuan dengan konsentrasi 5 ml.l-1 pada nimfa instar 2 WBC yang diinfestasikan pada tanaman padi dalam polibag. Hasil penelitian menunjukkan bahwa POC menghambat 46,64% pertumbuhan B. bassiana secara in vitro. Namun, keefektifan campuran B. bassiana + POC sama baiknya dengan B. bassiana secara tunggal. Hal ini menunjukkan POC dapat diaplikasikan berselang-seling dengan B. bassiana untuk mengendalikan WBC pada padi.
