Abstract

The research objective was to know ability of antagonistic microbes to control bacterial wilt on potato in the field. This research was carried out at Serang Village, Karangreja Subdistrict, Purbalingga Regency from June up to August 2012. The antagonist, originally isolated from potato field, was Bacillus sp. B2 and B4, and Pseudomonas sp. P19 and P20. Based on the research result, Pseudomonas P19 could control the disease on potato with delaying incubation period of 78.95%, suppressing disease intensity of 51.57%, decreasing final pathogenic population of 99.74%, and inducing plant resistance with increasing saponin, tannin, and glycoside content. However, the antagonist could not increase growth and yield of potato.  Keywords: antagonistic microbes, bacterial wilt, potato

Abstract

Background: Shallot cultivation in the rainy season faces the constraints of more severe plant disease problems. Utilization of mixed biopestisda Trichoderma harzianum, Bacillus sp. B8 and Pseudomonas flourescens P8 as well as proper cultivation techniques have not been adopted by farmers. It is necessary to assist farmers in implementing the technology The objectives of the activity are: assisting farmers in implementing the shallot cultivation technology package appropriately, increasing the quantity and quality of crop production, and increasing farmers' income through increasing farm efficiency. Method: The farmers participating in the activity are members of the farmer group "Lestari" Tambak Sogra Village, Sumbang District, Banyumas Regency. Technology transfer method through demplot assistance. The biopesticide technology package and environmental manipulation are compared to the conventional package of synthetic chemical pesticides. Data on the growth and yield of technological plot crops compared to conventional plots. The large number of farmers who can independently apply the technology is observed.  Results: mentoring activities showed that farmer group members were able to independently implement technology packages. The use of biopesticides and proper cultivation techniques can produce growth and yield equivalent to the use of synthetic chemical pesticides. Conclusion: 80% partner farmers can apply technology packages, the use of biopesticides is able to substitute the use of synthetic chemical pesticides, technology packages are able to increase 5.9% of shallot bulbs and reduce 75% production costs.

Abstract

Abstract: Permasalahan dalam budidaya tanaman pertanian terutama adalah adanya serangan hama dan penyakit tanaman. Petani selalu menggunakan pestisida kimia untuk mengendalikannya, namun, penggunaan yang tidak bijaksana dapat menyebabkan dampak negatif. Alternatif pengendalian yang aman dan ramah lingkungan diperlukan, salah satunya menggunakan pestisida organik berbasis metabolit sekunder mikroba antagonis. Pengetahuan akan pembuatan dan aplikasi pestisida organik masih belum dikenal oleh petani muda dari daerah tertinggal, sehingga perlu dilakukan pelatihan pembuatan pestisida organik dan cara aplikasinya. Pelatihan dilakukan selama satu hari dengan pendampingan selama tiga bulan, di training center Desa Sumberjati, Kecamatan Jatiroto, kabupaten Mojokerto, yang diikuti 12 petani muda dari Nusa Tenggara Timur, Pulau Nias, dan Kalimantan Barat. Pelatihan diberikan dalam bentuk pemberian materi terkait pesitida organik dan aplikasinya, pengenalan mikroba antagonis, pembuatan pestisida organik secara praktis, pembuatan alat infus sederhana, dan cara aplikasi pestisida organik ke tanaman buah. Hasil pelatihan menunjukkan adanya peningkatan pengetahuan dan ketrampilan peserta terkait materi yang diberikan. Pemahaman akan hama dan penyakit tanaman, dampak negatif pestisida kimia, peran penting pestisida organik, pembuatan pestisida organik secara mudah dan praktis, dan aplikasinya pada tanaman budidaya dapat diterima dan dipraktikkan. Pelatihan pembuatan alat infus sederhana dapat dipraktikkan dengan mudah. Pengetahuan dan ketrampilan peserta dapat sebagai bekal untuk dipraktikkan dan ditularkan ke petani lainnya ketika peserta Kembali ke daerah masing-masing.

Abstract

Chili production is frequently hampered by Aphis sp. infestations, necessitating eco-friendly biological control alternatives. Although the predator Menochilus sexmaculatus shows potential, previous researchers explicitly noted a lack of synthesized data quantifying its specific predation rates and predator-to-prey ratios. This study aims to evaluate the biocontrol efficacy of M. sexmaculatus against aphids on chili. Following PRISMA protocols, a Systematic Literature Review (SLR) used thematic analysis on articles (2017–2026) from Scopus, Google Scholar, and ScienceDirect, using keywords "Menochilus sexmaculatus", "aphids", and "chili" under strict inclusion criteria. Synthesized findings indicate that M. sexmaculatus exhibits substantial predation efficacy, marked by high consumption rates and rapid population suppression. Higher predator-to-prey ratios significantly accelerate pest suppression without disrupting ecological dynamics. In conclusion, M. sexmaculatus serves as a potent agent to reduce aphid population density in sustainable agriculture. Integrating predator conservation into pest management is recommended, while future research should focus on mass production techniques.
