THE EFFECT OF COMBINATION OF FUNGUS Paecilomyces fumosoroseus, STICKY TRAP, AND INSECTICIDE IMIDACLOPRID ON Empoasca sp.

Abstract

<p>Untuk memperoleh cara pengendalian yang efektif dan efisien sesuai dengan konsep Pengendalian Hama Terpadu telah dilakukan penelitian efektivitas berbagai kombinasi perlakuan terhadap <em>Empoasca </em>sp. pada tanaman teh. Pengujian dilakukan di Kebun Percobaan Gambung (1.250 mdpl) dan dirancang dalam Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 3 ulangan. Perlakuan yang diuji meliputi:  A. <em>Paecilomyces fumosoroseus (</em>Pfr); B. Lem perangkap (LP); C. Imidakloprid (I); D. Pfr + LP; E. Pfr + Ir; F. LP + Ir; G. Pfr + LP + Ir; dan H. kontrol. Pfr diperbanyak pada medium beras dengan dosis aplikasi 2,5 kg ha<sup>-1</sup> dan imidakloprid 0,125 L ha<sup>-1</sup> diaplikasikan dengan cara disemprotkan, sedangkan lem perangkap dipasang di tengah-tengah plot berukuran 5 m x 5 m. Parameter pengamatan terdiri dari intensitas serangan <em>Empoasca </em>sp.<em>, </em>populasi <em>Empoasca </em>sp., dan produksi pucuk. Hasil penelitian menunjukkan bahwa setelah 3 kali aplikasi semua perlakuan menunjukkan penurunan intensitas serangan <em>Empoasca </em>sp. Setelah aplikasi keempat, perlakuan kombinasi LP + Ir secara konsisten menunjukkan efektivitas yang lebih tinggi dari perlakuan lainnya. Pada pengamatan keenam, rata-rata intensitas serangan <em>Empoasca </em>sp. pada perlakuan kombinasi LP + Ir sebesar 15,95% dengan rata-rata populasi 0,67 ekor per plot. Sementara itu, produksi pucuknya lebih tinggi 33,64% dibandingkan dengan kontrol.</p><p> </p><p>In order to obtain an effective and efficient control method in integrated pest management, a research to know the effectiveness of combination treatments on <em>Empoasca</em> sp. on tea plant had been conducted. The trial was carried out at Gambung Experimental Station (1,250 masl) and designed in Randomized Complete Block design (RCB), with 8 treatments and 3 replications. The treatment tested comprised with A. <em>Paecilomyces fumosoroseus</em> (Pfr); B. sticky trap (ST); C. imidacloprid (I); D. Pfr + ST; E. Pfr + I; F. ST + I; G. Pfr + ST + I; and H. control. Pfr multiplied in rice medium 2.5 kg ha<sup>-1</sup> and imidacloprid 0.125 L ha<sup>-1</sup> were sprayed, while sticky trap was set in the middle of 5 m x 5 m plot. The parameters observed were attack intensity of <em>Empoasca</em> sp., population of <em>Empoasca</em> sp, and tea shoot production. The results showed that after 3 times application of all treatments revealed a decrease in the attack intensity of <em>Empoasca</em> sp. After the fourth application, combination treatment of sticky trap (ST) + imidacloprid (I) consistently showed higher efficacy than other treatments. In the sixth observation, the average of <em>Empoasca</em> sp. attack intensity of combination treatment (ST + I) was 15.95% with an average population of 0.67 <em>Empoasca</em> sp. per plot. In the meantime, tea shoot production was 33.64% higher compared with control.</p>
