<p><strong>(<em>The Use of Rain Shelter and Biopesticide in off Season Chilli Cultivation to Reduce Yield Losses and Infestation of Pest and Diseases</em>)</strong></p><p>Penggunaan rain shelter merupakan solusi untuk mengatasi permasalahan budidaya cabai di luar musim, yaitu kondisi musim hujan berkepanjangan. Peranan sumber daya hayati lokal termasuk tumbuhan sebagai biopestisida (Atecu) perlu ditingkatkan untuk mengatasi masalah mahalnya biaya produksi, namun mampu menekan kehilangan hasil akibat OPT dan menjaga mutu produk. Tujuan penelitian mendapatkan teknologi budidaya cabai off season yang dapat mengurangi kehilangan hasil dan serangan OPT ≥30%. Penelitian dilaksanakan di KP Margahayu Lembang, dari bulan Agustus 2016 sampai dengan bulan Maret 2017. Plot penelitian disusun berdasarkan rancangan acak kelompok (RAK) terdiri atas enam perlakuan dan empat ulangan. Perlakuan yang digunakan adalah bentuk rain shelter (bentuk datar dan melengkung) yang dipasang pada waktu tanam dan musim penghujan dikombinasikan dengan penggunaan Atecu 10 ml/l dan tanpa rain shelter + Atecu 10 ml/l serta teknologi konvensional. Hasil penelitian menunjukkan bahwa: (1) pertumbuhan tanaman cabai (tinggi dan lebar kanopi) yang ditanam di bawah rain shelter berbeda nyata masing - masing sebesar (14,23 cm dan 3,17 cm) serta mempunyai jumlah cabang yang lebih banyak (12,5) dibandingkan dengan tanaman cabai yang ditanam di lahan terbuka, (2) kombinasi penggunaan shelter dan Atecu 10 ml/l efektif mengendalikan OPT penting pada tanaman cabai merah dengan tingkat efikasi berkisar antara 33,56–75,0% serta dapat mengurangi penggunaan pestisida sebesar 50% bila dibandingkan dengan teknologi konvensional, dan (3) bentuk rain shelter yang paling baik adalah bentuk melengkung yang dipasang pada musim penghujan dan mampu meningkatkan hasil panen sebesar 26,32% atau sebesar 20,59 ton/ha. Dari hasil tersebut dapat direkomendasikan bahwa penggunaan rain shelter sebagai salah satu teknologi budidaya cabai off season.</p><p><strong>Keywords</strong></p><p><em>Capsicum annuum</em> L; Rain shelter; Biopestisida Atecu; Budidaya di luar musim; Hama dan penyakit</p><p><strong>Abstract</strong></p><p>The use of rain shelter is solution to solve chilli cultivation problems during rainy season which has long period rainy season.

Bemisia tabaci (Gen.) (Homoptera: Aleyrodidae) is one of the most serious pests on tomato. It is mainly controlled by chemi-cal means, requiring some 25 sprays during the average growing season. The extensive and repeated use of insecticides has dis-rupted the natural balance between this pest and its natural enemies. In this study, Menochilus sexmaculatus F. was evalu-ated as a possible biological control agent of B. tabaci and its effect on Gemini virus infestation. The study was conducted at the experimental station of the Indonesian Vegetables Research Institute (IVeGRI) in Lembang, West Java (1,250 m above sea level) from August to December 2008. The experimental plots consisted of 0.35 ha of tomato (± 100 m2 per plot) and spatially separated with four rows of maize (a minimum of 1 m) inter-plot distance to prevent cross-contamination among plots. The experiment was arranged in completely randomized block design with eight treatments and four replications. M. sexmaculatus were released at 24 days after planting. The treatments were designed according dosages and schedules at three released populations (i.e. 10 predators per plot, 20 predators per plot, and 10 predators per plot at vegetative stage followed by 20 predators per plot at generative stage); two places of release (center and edge of the plot); and two schedules of release (weekly and biweekly). Efficacy of the predator was measured in terms of the density of B. tabaci, both before and after release of the predator and its effect on Gemini virus infestation. The result indicated the potential use of M. sexmaculatus to control B. tabaci and its effect on Gemini virus infestation on tomato. Reductions in B. tabaci populations and subsequent tomato yields were significant. B. tabaci population in plots receiving 10 predators showed 73.62% and 75.75% reductions by the end of experiment. The incidence and intensity of Gemini virus were consistently and significantly lowest and tomato yield gain was observed when 10 predators were released at weekly intervals. It is suggested that release of M. sexmaculatus against B. tabaci on tomato may be offered as an alternative solution to increase implementation of biologically-based B. tabaci management. <br /><br />

Beauveria bassiana is one of the entomopathogen fungi which is known as biological control agent of cocoa pod borer and cocoa mirids (Helopeltis spp.). Because of its effectiveness in the fields is still not consistent, so we conduct a research with the objective to know the possibility of Beauveria bassiana to be established as a endophyte. Various fungal entomopathogens have already been reported as endophytes and the various methods used to inoculate the plants with B. bassiana were partially effective. The research has been conducted in laboratory of Plant Protection, Indonesian Coffee and Cocoa Research Institute by inoculating of cocoa seeds and cocoa nursery with B. bassiana suspension.  The trial was arranged  by randomized complete block design with a factorial arrangement. The factor were spore concentration of B. bassiana (0; 2; and 4 g/ 10 l) and cocoa varieties (family of ICS 60, TSH858, and hybrid). The trial were use  four replications. The results showed that the fungal entomopathogen B. bassiana was established as an endophyte in cocoa seedling, both from cocoa seeds and nursery application. Percentage of existence of B. bassiana colonies as endophytes one month after seeds application were ICS 60 amounted to 93.3 % both on concentration treatments, while the families of TSH 858 by 80 % and 86.67 % respectively in 2 g and 4 g per 10 l of B. bassiana spores concentration treament.. The lowest percentage was in hybrids, which amounted to 66.67% and 50%. B. bassiana colonies was exixtence as an endophyte in culture from root, stem and leaves of cocoa seedling up to 5 months post inoculation. While the application on nursery by soil drenshing, leaf spraying, and stem injection , it was known that B. bassiana colonies were found in the tissues of leaves, stems, and roots until two months after application. Colonies of B. bassiana as endophytes still exsist until six weeks after nursery was planted in the field.

ABSTRACT The population increase and the need of intensifying food production, coupled with the scarcity of water resources, have led to the search of alternatives that reduce consumption and optimize the water use during cultivation. In this context, hydrogels become a strategy in agricultural management, due to their water retention capacity in the soil and availability to plants. This study aimed at evaluating the efficiency of hydrogels on the development and production of cowpea bean ('Sempre-verde' cultivar) under water stress, in a greenhouse. The experiment was performed in a randomized block design, with five replications, in a 4 x 5 factorial scheme, consisting of four types of hydrogel (Hydroplan-EB HyA, with granulometry of 1-3 mm; Hydroplan-EB HyB, with granulometry of 0.5-1 mm; Hydroplan-EB HyC, with granulometry < 0.5 mm; Polim-Agri, with granulometry of 1-0.5 mm) and five concentrations (0 g pot-1; 1.5 g pot-1; 3 g pot-1; 4.5 g pot-1; 6 g pot-1). The following traits were evaluated: number of pods per plant, number of grains per pod and grain yield. The highest concentration (6 g pot-1) resulted in a higher number of pods and yield for all the hydrogels, especially for HyC and Polim-Agro, which presented 7.4 pods plant-1 and 7.0 pods plant-1, with yield of 15.43 g plant-1 and 16.68 g plant-1, respectively. The use of hydrogel shows to be efficient for reducing yield losses under water stress.

<p>Perkembangan varietas-varietas bawang merah di suatu daerah ditentukan oleh keserasian dengan lingkungan, potensi hasil, toleransi terhadap serangan organisme pengganggu tumbuhan (OPT), serta umur dan mutu hasil. Penelitian bertujuan untuk menguji penampilan beberapa klon bawang merah dan hubungannya dengan intensitas serangan OPT penting. Penelitian dilaksanakan di Brebes dan Tegal (Jawa Tengah) dari Bulan Juni sampai dengan September 2011. Perlakuan yang diuji ialah 10 klon bawang merah hasil silangan tahun 2004 dan 2005, serta dua varietas bawang merah sebagai pembanding (Bauji dan Bima Brebes). Rancangan percobaan yang digunakan ialah acak kelompok dan diulang tiga kali. Parameter yang diamati ialah pertumbuhan tanaman (tinggi tanaman, jumlah daun, dan jumlah anakan), hasil panen, dan serangan OPT penting. Hasil penelitian menunjukkan bahwa klon no. 2005/1 dapat beradaptasi dengan baik di Brebes dan Tegal, mampu menghasilkan produksi tertinggi masing-masing sebesar 9,95 dan 17,50 t/ha, mempunyai diameter umbi terbesar (1,87 dan 2,41 cm), bentuk umbi bulat, dan berwarna merah tua, sedangkan klon no. 2004/11 mempunyai pertumbuhan dan  produktivitas yang tinggi, relatif toleran terhadap serangan Spodoptera exigua, Alternaria porri, dan Colletotrichum gloeosporioides, diameter umbi (1,67 dan 1,96 cm), bentuk umbi bulat,  dan berwarna merah tua, sedangkan klon no. 2004/10 dan no. 2005/19 sangat rentan terhadap serangan hama S. exigua, penyakit A. porri, dan C. gloeosporioides. Klon-klon yang mempunyai tingkat serangan rendah/toleran terhadap OPT merupakan klon harapan bawang merah toleran/tahan OPT. Namun demikian, penggunaan pestisida sesuai dengan konsep pengendalian hama terpadu (PHT) masih tetap diperlukan terutama apabila serangan OPT tersebut mencapai ambang pengendalian yang ditetapkan.</p><p> </p><p>The development of shallots varieties in one location depends on the genetic adaptability, yield potential,  tolerance to pest and diseases, harvest date, yield and quality.

The trial were laid out in a completely randomized block design and each treatment was replicated three times. The parameters used for evaluating these clones were plant height, no. of sprout,  no. of leaves, yield and pests and diseases incidence. The results showed that considering overall performance, clone no. 2005/1 gave the highest yield (9.95 and 17.50 t/ha), and diameter of bulb (1.87 and 2.41 cm) in Brebes and Tegal respectively, clone no. 2004/11 produced growth and good yield  and showed tolerance to Spodoptera exigua, Alternaria porri, and Colletotrichum gloeosporioides, bulb diameter (1.67 and 1.96 cm) with dark red color,  while clone no. 2004/10 and no. 2005/19 were identified as the most susceptible clones to S. exigua, A. porri, and C. gloeosporioides. This suggests that some of shallots clones could be good candidates for the new varieties of shallots. However, the use of pesticides in IPM concept were still needed especially if the incidence of pests and diseases reach the action threshold.</p>

The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9.8% as compared to chemical treatment. T4 was also more efficient than T5 because it uses less biological agents. The advantage of biological agents is compatible if they were used together with predators such as Oxyopes sp., Paederus sp. and Coccinella sp; and also Telenomus sp. and Trichogramma sp. parasitoids. On the other hand, the chemical pesticides (T6) killed all existing natural enemies. Therefore, T4 could be recommended for controlling mungbean pests and diseases.
