Abstract
Watery Extract Compost (WEC) is a liquid fertilizer that has been reported can be used as a biological control of plant pests and diseases. One of the entomopathogen which was widely used is Beauveria sp. This research was aimed to investigate survival and virulence of Beauveria sp. that was added into WEC after storage to planthopper and rice bug. The compost used in this study was made using Trichoderma sp. as a starter. The fungus Beauveria sp. used in this study was obtained from corn rhizosfer. The fungus was added into WEC before storage. The treatment were WEC suspension which were keep for 1, 2, 3, 4, 5 and 6 months. Each of experimental unit consist of 20 planthopper or rice bug, with ratio 1 : 1 for male and female. The result showed that after 6 months storage, the fungus Beauveria sp. which was added into WEC was still had capability to infect and cause mortality of planthopper and rice bug. After 6 months storage, the mortality of planthopper caused by WEC-Beauveria application reach > 50%. Meanwhile, the mortality of rice bug reach 45%.
