“…From 2001 to 2008, national spending on agriculture increased from 11 billion rupiah to 53 billion rupiah, which is an average increase of 11% annually ( Armas et al, 2012 ). Plant and animal diseases are primary constraints affecting agricultural production, especially in tropical countries such as Indonesia ( Magarey et al, 2010 ; Prabaningrum and Moekasan, 2014 ; Drenth and Guest, 2016 ). Bacterial wilt disease, caused by members of the Ralstonia solanacearum species complex, is a serious disease of crop plants in Indonesia.…”

Ralstonia solanacearum species complex phylotype IV strains, which have been primarily isolated from Indonesia, Australia, Japan, Korea, and Malaysia, have undergone recent taxonomic and nomenclatural changes to be placed in the species Ralstonia syzygii. This species contains three subspecies; Ralstonia syzygii subsp. syzygii, a pathogen causing Sumatra disease of clove trees in Indonesia, Ralstonia syzygii subsp. indonesiensis, the causal pathogen of bacterial wilt disease on a wide range of host plants, and Ralstonia syzygii subsp. celebesensis, the causal pathogen of blood disease on Musa spp. In Indonesia, these three subspecies have devastated the cultivation of susceptible host plants which have high economic value. Limited knowledge on the ecology and epidemiology of the diseases has hindered the development of effective control strategies. In this review, we provide insights into the ecology, epidemiology and disease control of these three subspecies of Ralstonia syzygii.

The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an invasive pest from America and has recently become an important pest in Indonesia. In their new environment, these pests have very high migratory and adaptive skills, as well as aggressive feeding habits. The aim of this research was to monitor the distribution, percentage of attacks, and damage caused by S. frugiperda on maize fields in the Karo District of North Sumatra Province. The study was conducted using a survey method at various altitudes and the sample unit was determined using the diagonal method. Each sample unit has a size of 2 × 2 m2. The age of maize crop used as the sample is 2-4; 5-6; 7-8; 9-10; and 11 weeks after planting (wap). Symptoms of attack, number of larvae population, and percentage of FAW attack were observed directly on plants. The results showed that FAW spread evenly at various altitudes, with the highest population at an altitude of 500-1,000 m.a.s.l at the age of 2-4 wap with a larval population density of 14.20 individual/unit sample. The highest percentage of attack was found at an altitude of 500-1,000 m.a.s.l, namely 82% at 2-4 wap. The highest attack on leaves occurred at an altitude of 500-1,000 m.a.s.l (70.6%) at the age of 2-4 wap.

The control of aphids pests in chilli plantation often uses scheduled chemical control. This study aims to determine the development of aphid populations in the vegetative phase of chili plants treated with biochar from agricultural waste and trichokompos, and its control based on the threshold of control. The experiment was conducted on Chili Varietas Kencana of vegetative phase in Sangir Tengah Village, Kayu Aro Subdistrict, Kerinci Regency in 2016. The planting of chili was carried out with five treatments: 1) Trichokompos 10 ton/ha and 2 ton/ha of bagasse biochar; 2) Trichokompos 10 ton/ha and 2 ton/ha of corncob biochar; 3) Trichokompos 10 ton/ha and 2 ton/ha of rice husk biochar; 4) Trichokompos 10 ton/ha; and 5) Control (farmer technology). Each treatment was repeated 4 times. The environmental design used is Group Random Design (RAK). Data collection through observation of population number of aphids done every week. Control measures with the use of pesticides are carried out after the population passes the economic threshold. The results showed that the use of agricultural waste biochar (rice husk, corncob, bagasse) and trichokompos did not significantly affect the number/population of aphids. Chemical control of aphids on chili plants in the vegetative phase based on the control threshold can reduce the frequency of insecticide application up to 50%.Keywords: control threshold, insecticide, chili pest AbstrakPengendalian hama kutu daun pada tanaman cabai sering menggunakan pengendalian kimia yang terjadwal. Penelitian ini bertujuan untuk mengetahui perkembangan populasi kutu daun pada fase vegetatif tanaman cabai yang diberi perlakuan biochar asal limbah pertanian dan trichokompos dan pengendaliannya berdasarkan ambang kendali. Penelitian dilaksanakan pada pertanaman cabai varietas Kencana fase vegetatif di Desa Sangir Tengah, Kecamatan Kayu Aro, Kabupaten Kerinci pada tahun 2016. Penanaman cabai dilaksanakan dengan lima perlakuan yaitu : 1) Trichokompos 10 ton/ha dan biochar ampas tebu 2 ton/ha; 2) Trichokompos 10 ton/ha dan biochar tongkol jagung 2 ton/ha; 3) Trichokompos 10 ton/ha dan biochart sekam padi 2 ton/ha; 4) Trichokompos 10 ton/ha; dan 5) Kontrol (teknologi petani). Masing-masing perlakuan diulang sebanyak 4 kali. Rancangan lingkungan yang digunakan adalah Rancangan Acak Kelompok (RAK). Pengumpulan data melalui pengamatan jumlah populasi kutu daun yang dilakukan setiap minggu. Tindakan pengendalian dengan penggunaan insektisida dilakukan setelah populasi melewati ambang ekonomi. Hasil penelitian menunjukkan bahwa penggunaan biochar limbah pertanian (sekam padi, tongkol jagung, ampas tebu) dan trichokompos tidak berpengaruh nyata terhadap jumlah/populasi kutu daun. Pengendalian kimia kutu daun pada tanaman cabai varietas Kencana pada fase vegetatif yang dilakukan berdasarkan ambang kendali, dapat menurunkan frekuensi aplikasi insektisida sampai 50%.Kata kunci : ambang kendali, insektisida, hama cabai
