Efektivitas Pestisida Nabati Terhadap Pengendalian Hama Kutu Kebul (Bemisia tabaci Genn.) pada Tanaman Tomat (Lycopersicum esculentum Mill.)

his observation aims to determine the level of effectiveness of the organic pesticide garlic and tobacco against the control of whitefly pests (Bemisia tabaci) and production of tomato (Lycopersicum esculentum) which was conducted from 3rd October until 20th December 2022 at UNISKA Kediri field laboratory. The study was conducted at the UNISKA Kediri field laboratory with a known pH of 5 with sandy loam soil type was conducted from October 03, 2022 to December 20, 2022. The research method used a non-factorial Randomized Group Design. The factors is type  of vegetable pesticides (garlic and tobacco) with each consisting of four concentration levels of 0%, 20%, 40% and 60% so that there are 8 kinds of combination, carried out as many as 4 replicates and 3 samples of tomato plants were taken and used 96 sample of plants and about 1000 whitefly. After data was obtained, a varians analysis was carried out if there was continued with BNT 5% test. From the observation, it is known that the types of pesticides have a significant effect on the mortality rate of whitefly pests, while the concentration have a very significant effect on the mortality rate of whitefly with abest dose is 60% , but there is no interaction between the two single factors. In addition, the application of the organic pesticides does not have an effect on the growth and production of tomato, this is because organic pesticide isn’t type of nutrients that can help the growth and production on tomatoes    Tujuan dari penelitian ini untuk mengetahui tingkat efektivitas penggunaan pestisida nabati bawang putih dan tembakau terhadap pengendalian hama kutu kebul (Bemisia tabaci Genn.) pada tanaman tomat (Lycopersicum esculentum Mill.) serta mengetahui konsentrasi yang efektif dari dua macam pestisida nabati tersebut. Penelitian dilaksanakan di Laboratorium lapang UNISKA Kediri dengan pH diketahui 5 dengan tipe tanah lempung berpasir. Penelitian dilaksanakan pada 03 Oktober 2022 sampai 20 Desember 2022. Metode penelitian menggunakan Rancangan Acak Kelompok  non faktorial. Yaitu macam pestisida nabati (bawang putih dan tembakau) denagn masing-masing terdiri empat level konsentrasi 0%, 20%, 40% dan 60% sehingga terdapat 8 macam perlakuan, dilakukan sebanyak 4 kali ulangan dan diambil sebanyak 3 sampel tanaman tomat sehingga sampel tanaman sebanyak 96 tanaman dan kutu kebul sebanyak  ± 1000 ekor kutu kebul. Setelah data didapatkan maka dilakukan analisi sidik ragam dan dilajutkan dengan uji BNT 5% bila terjadi pengaruh nyata. Dari penelitian yang dilakukan diketahui bahwa macam pestisida nabati memiliki pengaruh sangat nyata terhadap tingkat mortalitas hama kutu kebul, dengan tingkat mortalitas yang paling tinggi adalah pada pestisida nabati berbahan tembakau dengan dosis konsentrasi 60%. Selain itu pemberian pestisida bawang putih dan tembakau tidak memiliki pengaruh terhadap pertumbuhan dan produksi tanaman tomat, hal ini dikarenakan pestisida nabati bukanlah jenis nutrisi yang mampu membantu pertumbuhan pada tanaman tomat dan produksi tanaman     &nbsp
