Pest Control Technology for Plutella Xylostella L. on Green Mustard (Brassica Juncea L.) Using Bacillus Thuringiensis in Tukungan Soil

Abstract

Green mustard (Brassica juncea L.) is a popular vegetable among the people. Green mustard leaves are commonly used as complementary ingredients such as chicken noodle, meatballs, etc. These vegetables are easily accessible to traditional markets, supermarket, and mall. The main obstacle in cultivating green mustard is Plutella xylostella attack. P. xylostella pests can attack both vegetative and generative, striking at the shoots and leaves of plants from breeding to harvesting. One of the effective and safe controls is the bioinsecticide Bacillus thuringiensis. Tukungan soil is a swamp land management technology that aims to diversify commodities that can be planted. This technology is very helpful in utilizing and maximizing existing agricultural land, especially in South Kalimantan. The bioinsecticide material used is a strain of B. thuringiensis which is the Turex WP. This research aims to determine the best dose of bioinsecticide B. thuringiensis (Turex WP) in controlling P. xylostella pests, increasing growth and yield of green mustard in tukungan soils. The research used a one-factor randomized block design, namely the dose of bioinsecticide (Turex WP) consisting of five treatments: p0 = 0 g/L, p1 = 0.5 g/L, p2 = 1 g/L, p3 = 1.5 g/L, and p4 = 2g/L. The results showed that the bioinsecticide B. thuringiensis (Turex WP) with a dose of 2 g/L was effective in controlling P. xylostella pests, increasing growth and yield of green mustard in tukungan soils.

PEMANFAATAN PUPUK KANDANG UNTUK BUDIDAYA SAWI (Brassica juncea L.) DI TANAH TUKUNGAN

“…dan Plutella maculipennis dilakukan pengendalian menggunakan cara mekanis yaitu mencari ulat serta membunuhnya. Jika pengendalian secara mekanis tidak teratasi, maka dilakukan pengendalian secara biologi yaitu menggunakan Turex WP dengan dosis 2 g Pemanfaatan Pupuk Kandang Untuk Budidaya Sawi (Brassica juncea L.) Di Tanah Tukungan (Heiriyani .T., Riza A.S., dan Helwenda) L -1 (Rizali et al, 2021). Pengendalian penyakit Xanthomonas campestris dan Alternaria brassicae dengan cara menyemprotkan fungisida dithane M-45 dengan konsentrasi anjuran yaitu 2,5 g L -1 (Rahayu, 1997).…”

Respon Ketahanan Tanaman Caisim (Brassica Juncea L.) terhadap Intensitas Serangan Hama dan Penyakit setelah Pemberian Pupuk Kandang Kambing dan Pupuk Hayati Provibio®

“…B. thuringiensis adalah bakteri pelarut fosfat atau produk biostimulator untuk meningkatkan produksi tanaman secara keseluruhan (Delfim & Dijoo, 2021). Aplikasi B. thuringiensis (2 g/L) terbukti dapat menurunkan serangan hama sebesar 63,21% dan 69,86% pada tanaman berumur 6 minggu (MST) dan 8 MST (Rizali et al, 2021). Aplikasi campuran biourin dengan B. thuringiensis terhadap jumlah daun rusak tanaman sawi hijau menekan serangan hama belalang sebesar 27,23% (Hendrawati et al, 2015).…”
