<p>Pests are one of the main obstacles in improving mungbean production in Indonesia. Currently, conventional control by using synthetic pesticides is less successful because the population and damage due to the organism are still high. This study aims to evaluate the mungbean pest control technology by using biopesticide. The experiment was conducted using randomized block design, five treatments and five replicates. The treatments were P1: preventive of neem seed powder (NSP), entompothogenic virus which contain <em>Spodoptera litura</em> nuclear polyhedrosis virus (Virgra), and conidia of entomopathogenic fungi <em>Beauveria bassiana</em> (BeBas) application; P2: SBM, Virgra, and BeBas application based on economic threshold (ET); P3: application of synthetic pesticides based on schedule; P4: application of synthetic pesticides based on ET; and P5: without control. The results showed that the pests were armyworm (<em>Spodoptera litura </em>(Fabricius)), whitefly (<em>Bemisia tabaci </em>(Gennadius)), <em>Empoasca</em> sp., <em>Megalurothrips</em> <em>usitatus</em> (Bagnall), brown stink bug (<em>Riptortus</em> <em>linearis </em>(Fabricius)), green stink bug (<em>Nezara viridula </em>(Linnaeus)), and pod borer (<em>Maruca testulalis </em>(Geyer)). The application of NSP, Virgra, and BeBas, as preventive measures and the application of synthetic pesticides based on schedule effectively were suppressed pest population. In contrast, the application of biopesticides and synthetic pesticides based on ET did not suppress the development of major pests. The application of biopesticide based on ET are safe for the survival of natural enemies. Meanwhile, the application of synthetic pesticides can destroy existing natural enemies. Integrated management of NSP, Virgra, and BeBas, that are applied preventively are potential to be innovative technology for controlling the major mungbean pest to replace synthetic pesticides.</p>

This study aims to analyze the potency of Beauveria bassiana (Bb) and the best concentration on the population of whitefly Bemesia tabaci on horticultural crops. The method used was a Randomized Block Design (RAK) on eggplant and chili plants with 4 treatments, namely control, Bb 100g/10ltr water, 150g/10ltr water and 200g/10ltr water. Each treatment was repeated 5 times. Data analysis used analysis of variance and continued with the BNT test. The results of the potency test of Beauveria bassiana have the best concentration at 200g/10ltr of water. The average whitefly population on eggplant plants was 65.57%, the population decreased to 6.37% and chili with an average population of 39.37% chili, the population decreased to 15.87%. This is also influenced by agricultural systems in eggplant fields which often rely on synthetic pesticides which cause pests to become resistant and also destroy natural enemies. compared to whitefly pest populations in chili fields which often use organic materials that are far from pest resistance and anti-natural enemies. In addition, the leaves of the eggplant plant are larger than the chili leaves which allow them to lay more eggs and also have a number of trichomes as a shelter for whitefly from natural enemies (predators). The conclusion of the study was that Beauveria Bassiana had good potency at a concentration of 200g/10ltrair against the whitefly Bemesia tabaci on horticultural crops, both eggplant and chili plants. It is suggested to analyze the relationship between leaf structure and preference level of whitefly on horticultural crops

Shallot (Allium ascalonicum Linn.) constitutes one of the commodities that has important meaning for Indonesian people with the limiting factor in the production is the pest attack. One of these pest control techniques is by controlling technical culture of polyculture planting system. This research was conducted in July to October 2019 which was located in Banyuputih Village, Wringin District, Bondowoso Regency. This study used a Randomized Block Design (RBD) with six treatment, namely: P1 = polyculture of shallot + Lemongrass; P2 = polyculture of shallot + celery; P3 = Polyculture of shallot + mustard; P4 = Polyculture of shallot + Lemongrass + mustard; P5 = Polyculture of shallot + celery + mustard; P6 = Monoculture of shallot. Each treatment was repeated 4 times. Observation started at 30 days after planting. Data collection was done by observing directly on the sample plants. Sampling was carried out using Yellow trap and pit fall trap. Samples were taken at each plot 10 times with intervals of 4 days. Observations included collecting the pest insects and natural enemies that were found, counting the number of populations in each species, scoring towards the damage plants. The results showed that shallot planting by polyculture with different types of plants affected the population of pests and natural enemies as well as the level of diversity of insects in shallots. Planting shallots by polyculture has been proven to control pest populations compared to planting shallots by monoculture. Polyculture planting with two types of plants proved to be better than polyculture planting with three types of plants where the best treatment was found in P1, namely polyculture of shallot and lemongrass with the smallest pest population which was 17.5.

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.

ABSTRACT Bacterial wilt limits tomato production and resistant rootstocks could be important for the integrated management of the disease. Since there is an interaction between local bacterial strains and tomato genotype, this study aimed to evaluate 14 tomato rootstocks to bacterial wilt in the Mata mesoregion of Pernambuco state, Brazil. The rootstocks reaction to two sequevars of Ralstonia solanacearum and two of R. pseudosolanacearum was evaluated in four experiments carried out in the greenhouse using the completely randomized experimental design, with four replications composed of four plants each. Seven genotypes were selected to evaluate the reaction to bacterial wilt as rootstocks grafting in tomato plants ‘Tomini F1’ in a production area with disease history in the Chã Grande municipality, using randomized block design with four plants per treatment in each block. In the field experiment, disease symptoms were not observed in the grafted plants in ‘Guardião’, ‘Woodstock’, and ‘Yoshimatsu’. Regarding all experiments, ‘Guardião’ and ‘Muralha’ showed the best resistance levels and could be used in the integrated management of bacterial wilt and studied in plant breeding programs.

One type of pest that often attacks soybean plant leaves in tidal swamplands is the armyworm pest. The intensity of leaf damage due to armyworm attack in tidal swamps ranges from 30-95%, and can even lead to crop failure. In controlling pests in soybean plants in general, always rely on chemical insecticides. The use of these chemical insecticides has a negative impact on the environment. To overcome this, the control is directed towards environmentally friendly pest control by utilizing swamp plants as a botanical insecticide. The study used a randomized block design (RBD) with 3 treatments of swamp plant extracts (galam, kirinyuh, kepayang) and 3 controls, namely without control, botanical insecticide made from neem, chemical insecticide with the active ingredient kloraniliprol. The aim of this study was to obtain a swamp plant extract that could be used in controlling armyworm pests (Spodoptera litura). The results showed that the three types of swamp plants could be used as botanical insecticides in controlling armyworm pests, and has an effectiveness value above 70%. The highest effectiveness of botanical insecticides was obtained at the age of 75 DAP, namely Galam (78.29%), Kirinyuh (78.86%) and Kepayang (78.85%).
