The potato cyst nematode Globodera pallida is a major pest of the potato crop. Abamectin is a biological pesticide showing high nematicide activity, but its efficacy to control G. pallida has not been investigated to date. In this study, combination of different abamectin concentrations ranging from 1.125 to 36 µg/mL x exposure times from 24 to 384 h were tested on the nematode in a hatching test. Abamectin induced mortality with LD50 value in the range of 13.23 (after 24 h) to 2.90 µg/mL (after 384 h). A glasshouse experiment was also performed in pots filled with soil infected with G. pallida in the presence of sprouted potato tubers cultivar “Spunta”. Abamectin at 4.5, 9.0, 18.0 and 36.0 µg/mL was used in comparison with nematicide fosthiazate. The doses of 18 and 36 µg/mL significantly reduced number of eggs, juveniles, cyst/g soil and reproduction rate in comparison to both untreated control and fosthiazate treatment. Soil applications of abamectin provided significant G. pallida control with LD50 and LD99.9 of 14.4 and 131.3 µg/mL, respectively. These results indicate the efficacy of abamectin to control G. pallida on potato crops and its potential use in organic agriculture or in an integrated pest management program.

Identification and Control Test of Jabon Leaf Pest by Invitro        One of problem in jabon (Neolamarckia cadamba [Roxb.] F. Bosser) plantation is defoliator. Identification and control effort are needed to counter this problem. This research was intended to identify pest species attacking plant and do efficacy test of several chemical and biological pesticides against the defoliator. The statistical method of efficacy was Completely Randomized Design (CRD). Two pesticides prophenophos (0,1%) and dimethoate (0,1%) as chemical based organic pesticides and Bacillus thuringiensis(0,5 g/l) as biological pesticide were tested against the defoliator. Data was analyzed using Anova and Tukey test at 95% confidence level. The result showed that pest was identified as Dysarthria quadricaudata. Chemical and biological pesticides were effective to control the pest.Keywords: Neolamarckia cadamba, Dysarthria quadricaudata, prophenophos, dimethoate, pest. ABSTRAK        Salah satu persoalan pada hutan tanaman jabon (Neolamarckia cadamba [Roxb.] F. Bosser) adalah serangan hama perusak daun. Pengendalian diperlukan untuk mengatasi persoalan ini. Penelitian  bertujuan untuk mengidentifikasi spesies hama dan melakukan efikasi beberapa jenis pestisida kimia dan organik terhadap hama ulat daun jabon (N. cadamba). Metode yang digunakan adalah rancangan acak lengkap. Dua jenis pestisida kimia berbahan profenofos (0,1%), dan dimetoat (0,1%) serta pestisida organik berbahan dasar Bacillus thuringiensis (0,5 gr/lt) diuji terhadap hama ulat daun. Data dianalisis menggunakan Anova dan uji Tukey (CI = 95%). Hasil penelitian menunjukkan bahwa spesies hama yang menyerang tanaman jabon adalah Dysarthria quadricaudata. Jenis pestisida tersebut efektif mengendalikan hama ulat daun jabon.Kata kunci: Neolamarckia cadamba, Dysarthria quadricaudata, profenofos. dimetoat, hama

IbM program aimed at improving capability and skill of cadres and PKK members of RW 12 and 13 Karangklesem village in optimalizing narrow-land area in their neighbourhood through improving capability and skill on verticulture technology mastery on organic vegetables from the making of organic fertilizer, biological pesticide, seed seedling, planting media, planting, plant treatment, harvesting and post harvesting, and capability of vegetables (agribusiness) entrepreneurship. The next aim was to handle the household waste, to create beautiful, green, and aesthetic environment, and to earn additional income for the cadres and PKK members of RW 12 and 13 from their organic vegetable sales.The method used in this IbM program was training and direct practice, assisting, fostering, and partnership with the cadres and PKK members of RW 12 and 13 at Karangklesem village.Utilization of narrow-land area has been conducted around RW 12 and 13 at Karangklesem village by conducting the following activities: (1) Bioactivator making and liquid organic fertilizer and compost  training. The results were 20 liters bioactivator, 200 liters liquid organic fertilizer, and 750 kilograms compost, (2) the technique of making biological pesticide training; the result was 200 liters of biological pesticide, (3) organic vegetable virticultur technique training; the result was 47 sets of organic vegetables in verticulture system, (4) post-harvesting technique of organic vegetables, and (5) entrepreneurship training covering the training of book keeping, business analysis of verticulture organic vegetable and marketing management.The conclusion of this IbM program was that there was an improvement on capability and skill of the cadres and PKK members  of RW 12 and 13 Karangklesem village in mastering the verticulture technology of organic vegetables from the making of bioactivator, liquid organic fertilizer, compost, biological pesticide, seed seedling, planting media, planting and plant treatment, harvesting and post-harvesting treatment, and organic vegetable entrepreneurship

Bacillus thuringiensis is an agriculturally significant bacterium and common biological pesticide. B. thuringiensis strain MW was isolated from a freshwater stream in Mont Vernon, NH, and sequenced. A draft genome assembly of 5,935,630 bp with a G+C content of 34.86% and an N 50 value of 1,154,949 bp was generated.
