This study was carried out from August to November 2021. This study had 18 treatment units consisting of: A1: planting media fertilized with bokashi and covered with silver plastic mulch, A2: growing media fertilized with bokashi and without mulch, B1: growing media fertilized with Urea, SP36, KCL and covered with silver plastic mulch, B2: growing media fertilized with Urea, SP36, KCL without mulch, C1: planting media fertilized with Urea, SP36, KCL + bokashi and covered with silver plastic mulch, C2: planting media was fertilized with bokashi + Urea, SP36, KCL, without mulch. The results showed that the use of mulch and bokashi gave better results (least pest infestation of all treatment), but statistically there was no significant difference between the treatments on the observed variables.

Permasalahan yang dihadapi antara lain berupa keterbatasan dalam cara pemeliharaan tanaman apel dan sayuran, serta dalam hal pengendalian hama penyakit tanaman. Kegiatan PKM ini bertujuan untuk: (1) memperkenalkan metode budidaya tanaman secara sehat berkelanjutan; (2) membuat Trichokompos menggunakan isolat Trichoderma sp. koleksi Laboratorium Penyakit Tumbuhan Faperta Undana; (3) membuat dan mengaplikasikan pupuk organik cair dari limbah pertanaman dan peternakan yang diperkaya dengan EM4; (4) membuat perangkap lalat buah; dan (5) membuat dan mengaplikasikan pestisida nabati. Metode pelaksanaan adalah penyuluhan, diskusi, praktek, dan pembuatan demplot.Target kegiatan PKM ini telah tercapai. Petani telah menguasai pengetahuan tentang budidaya tanaman secara se...

Berbagai jenis OPT yang memengaruhi pertumbuhan dan perkembangan jeruk diantaranya Phtytopthora sp., Diplodia sp, virus triteza, Scirtotfrips citri, Diaprina citri, lalat buah. Masalah lain yang dihadapi oleh mitra adalah tidak memberikan pupuk bagi tanaman. PKM ini bertujuan untuk membimbing, membina, dan memberdayakan petani mengelola hama penyakit jeruk ramah lingkungan dengan menggunakan pupuk hayati dan biopestisida. Menjawab permasalahan petani metode yang digunakan adalah yaitu penyuluhan dan pelatihan, adobsi dan introduksi teknologi (demplot dan percobaan terapan teknologi yang murah dan ekonomis serta ramah lingkungan); dan pemberdayaan anggota kelompok tani melalui pendampingan dan evaluasi oleh tim pelaksana. Hasil pelaksanaan menunjukkan bahwa sebanyak 40% anggota kelompok tani mengenal jenis hama d...

Hasil pertaniannya adalah kentang, bawang putih , bawang merah, kacang merah, wortel, jeruk keprok Soe dan aneka sayuran seperti sawi dan kacang panjang. Potensi alam tersebut sangat mendukung perkembangan sektor pertanian dan industri wisata dalam meningkatkan pendapatan masyarakat. Hasil pertanian dijual ke pasar-pasar tradisional di sekitar Kabupaten Timor Tengah Selatan (TTS). Fatuulan adalah pemasok utama komoditi hortikutura terutama kentang lokal, bawang merah dan kacang merah. Tetapi, produksi pertanian tersebut masih tergolongi rendah karena umumnya pengetahuan dan keterampilan petani dalam kegiatan budidaya tanaman masih rendah seperti rendahnya pengetahuan petani tentang pupuk dan pemupukan, serta pengendalian hama dan patogen tanaman. Masalah-masalah utama yang dihadapi mitra adalah: (a) belum mengetahui dan memanfaatkan pupuk organik serta mengandalkan pengg...

While using chemical insecticides is not sustainable, the use of plant-based insecticides is thus recommended. This study aimed to determine the efficacy of Annona squamosa and Tephrosia vogelii seed extract mixture on the mortality of 3rd instar larvae of Helicoverpa armigera. A range of concentration, as treatments, were evaluated, i.e., 0.05%, 0.11%, 0.28%, 0.65%, 1.5% and a control (water only) applied with three replicates in each treatment. Ten larvae of H. armigera at each treatment were infested in baby corn, using the residue method. Mortality was observed at 24, 48, 72, 96, and 120 hours after treatment (HAT). Percent mortality of the 3rd instar of H. armigera larvae was analyzed using Probit Polo PC, then proceed with mixed activity analysis. The results showed that the mixture of A.squamosa + T. vogelii seeds extracts killed H. amigera larvae with the value of LC 50 and LC 95 of 0.07% and 2.07%, respectively. A mixture of A. squamosa seeds + T. vogelii seeds extract was synergistic to H. armigera larvae with combined index values at LC 50 and LC 95 were 0.53 and 0.58, respectively. Thus, the use of a mixture of A. squamosa seed extract and T. vogelii seed is more efficient because the raw materials used were less at low concentrations to control H. armigera larvae than the extract applied separately.

This germplasm needs to be preserved and developed to diversify non-rice alternative food. One of the main obstacles in cultivating potatoes is the presence of pests, but so far there have been no reports of pests on local potato plants from Soe from the two sub-districts, so this research needs to be done. This study aimed at an inventory of important pests on local potato plants from Soe as a database for early detection to prevent the occurrence of explosive pests. This research was conducted on potato plantations in Fatuulan Village, Ayofanu Village, Nunleu Village, and Nenas Village. The method used is a purpose survey at a specified sample point. A sampling of insect pests is done by direct observation and insect nets. The pests found were put in a killing bottle or 70% alcohol, collected, and identified. Observation variables include the type of pest, symptoms ...
