Abstract

[REDUCTION OF PESTICIDE RESIDUES Tebukunazol AND Trifloksistrobin ON ORGANIC BULB SHALLOT CROPS WITH BIOPESTICIDE BASED IN BULUGUNUNG VILLAGE, PLAOSAN, MAGETAN REGENCY]. Shallot plants are agricultural commodities that have a high and economic value. The continuous use of pesticides to increase Shallot production will harm the environment. The active pesticides of Tebukonazol and Triflooxystrobin are one of the fungicides to overcome moler disease. Maximum Residue Limit (BMR) on shallot bulbs for active substance Tebukonazol of 0.1 mg/kg while for active substances Trifloksistrobin of 0.01 mg/kg. To reduce the pesticide residues, efforts are needed through the application of biopesticides. This research was conducted in March-May 2021 in Bulugunung Village of Plaosan District of Magetan Regency. Analysis of pesticide residues Tebukonazol and Trifloksistrobin was carried out at the Laboratory of The Industrial Research and Consulting Center (BPKI) Surabaya. The research was one factor, conducted in a Complete Randomized Design (CRD) consisting of 4 treatments with 6 replications, namely: Treatment (A): Conventional cultivation, Treatment (B): Fobio (seeds and plants), Phonska Fertilizer, P-Phosfat, SP-36, KCl, and ZA, Treatment (C): Manure to the soil and Soil sterilization with Fobio, as well as pesticide application, Treatment (D): Giving soil manure and soil sterilization with Fobio, and the application of Fobio (seeds and plants). Data analysis was conducted in analysis of variance (ANOVA), followed by the the Honesty Significant Difference (HSD) at a level of 5% if the F test shows a significant effect. The results showed that the treatments (B) and (D) of Fobio applications in seeds and plants have the lowest pesticide residue values of Tebukonazol and Trifloksystrobin compared to treatments (A) and (C) that use chemical pesticides.

Abstract

Alternaria porri is a fungal pathogen that causes purple blotch on shallots, this fungus can cause crop yield loss of 3 – 57%. A. porri was obtained from the Sumber Brantas onion farm and then isolated by planting infected tissue. Streptomyces spp. is a filamentous bacterium that is abundant in the soil and can be used as a biological agent, decomposer and plant growth promote. Streptomyces spp. was obtained one isolate from shallot land location in Pare, Kediri, East Java (BMP: Bawang Merah Pare) and three isolates from Sidera, Palu, Central Sulawesi (BMS: Bawang Merah Sidera) (BMS1, BMS2, BMS3). The purpose of this study was to determine the efficacy of Streptomyces spp. to control A porri consist of in vitro and In vivo antagonist test. Antagonist test was carried out by dual culture method and the Streptomyces spp. which can inhibit the development of A porri would be used antagonist test   in vivo. The study was designed using a Factorial Complete Randomized Design with two factors, candidate isolates of biological control agents and concentrations of Streptomyces spp. be diluted into 5%, 10%, and 15%, it will applied on shallot plant Bauji variety. The results of the In vitro test shown the highest inhibition zone from BMP 17.75% while BMS1 13.75%, BMS2 8,75%, and 8.50%. in vivo test shown lowest disease severity value in BMP 15% concentration was 1.13% while diseases severity of BMS1 was 1.27%, and BMS2 was 1.80%. Therefore, Streptomyces spp. has potency as an alternative pesticide for sustainable agriculture.

Abstract

Fusarium wilt disease in red pepper plants is caused by the pathogenic fungus Fusarium sp. This disease is classified as an important disease of red chili plants because it can cause damage up to 50%. One of the efforts to overcome fusarium wilt disease is to use biological agents Streptomyces sp. which comes from the field of shallots and tomatoes in Pare, Kediri. The purpose of this study was to determine the effect of the application of Streptomyces sp. Against Fusarium wilt disease in red pepper plants with a wide range of application times. This study used a Factorial Complete Randomized Design with SP and BMP isolate type treatment, as well as application time treatment before planting, at the same time planting and after planting. Each treatment was repeated 5 times and given 5 plant units on each repetition. Observation parameters were carried out on the incubation period, disease severity, plant height, number of leaves, flowering age and number of flowers. Application Streptomyces sp. SP isolate with application time before planting showed the best results compared to other treatments. Keywords: Application Time, Fusarium sp., Streptomyces sp.  INTISARI                                                 Penyakit layu fusarium pada tanaman cabai merah disebabkan oleh jamur patogen Fusarium sp. Penyakit ini tergolong ke dalam penyakit penting tanaman cabai merah karena dapat menyebabkan kerusakan hingga 50%. Salah satu Upaya dalam mengatasi penyakit layu fusarium adalah menggunakan agensia hayati Streptomyces sp. yang berasal dari lahan bawang merah dan tomat di Pare, Kediri. Tujuan dari penelitian ini adalah untuk mengetahui mengetahui pengaruh apikasi Streptomyces sp. terhadap penyakit layu fusarium pada tanaman cabai merah dengan berbagai macam waktu aplikasi. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial dengan perlakuan jenis isolate SP dan BMP, serta perlakuan waktu aplikasi sebelum tanam, bersamaan tanam dan setelah tanam. Masing-masing perlakuan diulang sebanyak 5 kali dan diberikan 5 unit tanaman pada masing-masing ulangan. Parameter pengamatan dilakukan terhadap masa inkubasi, keparahan penyakit, tinggi tanaman, jumlah daun, umur berbunga dan jumlah bunga. Aplikasi Streptomyces sp. isolat SP dengan waktu aplikasi sebelum tanam menunjukkan hasil terbaik dibandingkan dengan perlakuan yang lain. Kata kunci: Waktu Aplikasi, Fusarium sp., Streptomyces sp.
