Trizelia, Busniah M, Agung Permadi A. 2017. Pathogenicity of entomopathogenic fungus Metarhizium spp. against predators Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae). Asian J Agric 1: 1-5. Metarhizium spp is an entomopathogenic fungus which has wide host range. Metarhizium spp can not only infect insect pests, but can also infect beneficial insects such as predators. The pathogenicity of four isolates of Metarhizium spp. was investigated against Menochilus sexmaculatus predator. Isolates of Metarhizium spp were isolated from rhizosphere of cacao, cabbage, chili, and rubber crops. The experiment was conducted by treating the fourth instar larvae with an appropriate conidial suspension of 108 conidia mL-1. The results showed that all isolates of Metarhizium spp were pathogenic toward beetle predator M. sexmaculatus. Mortality of larvae within seven days after application of conidial suspension varied between 27.50 to 67.50% and there were statistically significant differences among the tested isolates. Metarhizium spp. had also a significant affect in reducing pupation and adult emergence of M. sexmaculatus to below 30% and 3%, respectively. These studies indicate that entomopathogenic fungus Metarhizium spp was pathogenic to beetle predators, M. sexmaculatus.

Abstract

ABSTRAK Nagari Sungai Durian Kabupaten Solok merupakan salah satu nagari yang memiliki berbagai permasalahan seperti kekeringan, tingginya jumlah lahan tidur dan jauhnya akses. Tanaman utama yang ditanam saat musim hujan adalah padi sawah, namun sebagian besar lahan menjadi lahan tidur saat musim kemarau. Solusi yang dapat ditawarkan adalah dengan penanaman tanaman palawija yang lebih tahan terhadap kekeringan dan penggunaan rizobakteri sebagai agens pengendali hama dan penyakit. Selain sebagai agens pengendali hama dan penyakit, penggunaan rizobakteri juga sebagai PGPR (Plant Growth Promoting Rhizobacteria) yang mampu meningkatkan pertumbuhan dan hasil tanaman. Tujuan dari program pengabdian masyarakat ini adalah memberikan pengetahuan kepada masyarakat dalam budidaya tanaman palawija dengan aplikasi teknologi rizobakteri indigenos. Kegiatan ini dilakukan dengan cara sosialisasi dan demonstrasi plot. Adapun luaran yang didapat dari program pengabdian masyarakat ini adalah :1) Masyarakat mendapatkan pengetahuan serta menguasai teknik budidaya tanaman palawija yang baik (jagung, singkong dan ubi jalar); 2) pengetahuan mengenai teknologi pemanfaatan rizobakteri sebagai agens hayati dalam pengendalian hama dan penyakit tanaman serta peningkatan pertumbuhan dan hasil tanaman palawija; 3) Mendapatkan produk pertanian organik (jagung, singkong dan ubi jalar) yang bebas dari penggunaan pupuk dan pestisida sintetik. Kata kunci : Agens hayati, Rizobakteri, PGPR, Tanaman palawija ABSTRACT Nagari Sungai Durian of Solok District is one of the village that has various problems such as drought, high number of unused land and the distance of urban access. The main crops in this village grown during the rainy season are wetland paddy, but most of the land becomes unused during the dry season. The solution that can be offered is by planting crops that are more resistant to drought and the use of rhizobacteria as pest and disease control agents. In addition to pest and disease control agents, the use of rhizobacteria which also called PGPR (Plant Growth Promoting Rhizobacteria) that can increase growth and yield of plants. The purpose of this community service program is to provide knowledge to the community in the cultivation of secondary crops with the application of indigenous rhizobacteria technology. This activity is done by socialization and demonstration plot. The outcomes obtained from this community service program are: 1) Communities gain knowledge and master good cultivation of secondary crops (corn, cassava and sweet potatoes); 2) knowledge of rhizobacteria utilization technology as biological agent in plant pests and diseases control and improvement of crops' growth and yield; 3) Obtain organic agricultural products (corn, cassava and sweet potato) that are free from the use of synthetic fertilizers and pesticides.

Abstract

Nagari Sungai Durian of Solok District is one of the village that has various problems suchas drought, high number of unused land and the distance of urban access. In the cultivation of foodcrops required a lot of water such as rice, so that productivity is not optimal. For that the selection ofcorn as a cultivation plant is a possible thing because corn plants merupkan food crops that do notrequire much water. But some of the constraints faced when corn plant perspectives are low productivitydue to disruption of pests and diseases and soil less fertile. The solution that can be offered is by plantingcorn crops that are more resistant to drought and the use of rhizobacteria as pest and disease controlagents. In addition to pest and disease control agents, the use of rhizobacteria which also called PGPR(Plant Growth Promoting Rhizobacteria) that can increase growth and yield of plants. The purpose ofthis community service program is to provide knowledge to the community in the cultivation of corncrops with the application of rhizobacteria. This activity is done by socialization and demonstrationplot. This activity has been able to educate the general community about farmers about corn cultivationwith rhizobakteri application. From this activity also can be concluded that corn plant with applicationof Rhizobakteri have growth and yield higher than corn plant without application of Rhizobakteri.
