Abstract

Wood vinegar is a liquid made from steam cooled wood smoke in the sublimation process. Recently, this material is known to be used as a biopesticide, so it does not have side effects that are harmful to the environment, especially for non-target insects. Ambarwati et al (2013) reported that wood vinegar can control cabbage heartworm (Crocidolomia pavonana) and has an effect in accelerating its life cycle. In addition, wood vinegar can also increase the weight of Edamame soybeans almost twice (Ramli et al, 2020) According to Sri Hartati et al (2013) wood vinegar is also able to inhibit the growth of conidium up to 76%. Mustard greens are vegetables that have good commercial value, but the production is fluctuating. One of the factors that influence the fluctuation of mustard greens production is the presence of Spodoptera litura caterpillars. The development of botanical pesticide is needed to substitute chemical pesticide. This research purposed to obtain an effective concentration of wood vinegar and an appropriate application method to control S. litura caterpillars. This research was conducted in the Laboratory of Plant Pest and Diseases Faculty of Agriculture, Sebelas Maret University (UNS) and in Satriyan, Ngrundul, Kebonarum, Klaten starting from May until August 2020. This study was conducted using a completely randomized experimental design (CRD) with two factors. First factor is concentration of wood vinegar from rice husk (0%, 2%, 4%, 8%, dan 16%) and second factor is application method (leaf dipping method and larvae spraying method). The result showed that wood vinegar with various concentrations tested has no effective effect on S. litura and application methods that used have no different effect.

Abstract

The bean fly (Ophiomyia phaseoli) is a major pest of soybean in Indonesia which causes the plants to die early in growth. Most farmers use insecticide synthetics to control this pest. Therefore the alternative control of bean flies is needed to reduce reliance on farmer's usage of chemical pesticides. One of the alternative control is with application of husk ash that has a high silica content. This study examined husk ash to know the effect of husk ash to population and proportion of bean flies attacks. This research conducted in Pengkok Village, Kedawung, Sragen from June - September 2019. The method used was field experiment with a Randomized Completely Block Design (RCBD) with one factor, namely the dose of husk ash five levels (0 tons ha-1, 1.25 tons ha-1, 2.5 tons ha-1, 3.75 tons ha-1, and 5 tons ha-1) and five replications. The results showed that the application of husk ash not affected significantly on the adults of the bean fly population, but affected significantly the percentage of attacks only in the cotyledons. The application of rice husk ash can reduce the percentage of attack on the cotyledons by 2.11-3.04% than without husk ash application. The number of plant deaths apparently followed the populations of bean flies. Furthermore, the height of soybean with application looked taller than without application.

Abstract

Natural enemies play an important role in the rice field ecosystem in achieving pest population balance. The jajar legowo planting system is a planting system that provides empty space for rows of plants that are thought to affect the types and population dynamics of natural enemies. The aim of this study was to determine the effect of applying the jajar legowo cropping system to the types and populations of natural enemies of rice pests. The research was conducted from April-June 2022 in Karanglo Village, Polanharjo, Klaten and the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Universitas Sebelas Maret. The research was carried out in rice fields with conventional spacing systems (tegel) and jajar legowo 2:1. The variables observed were the type and population of predators and parasitoids along with the degree of parasitization of the rice pests. The results showed that the types of predators found in conventional land and Jajar Legowo were not different. The application of the jajar legowo cropping system increased the population of Paederus and Tetragnatha spider.
