Abstract

More than 400 thousand plant species have been identified as chemical ingredients and 10 thousand of them contain secondary metabolites that can be used as botanical pesticides. This research is experimental and aims to determine the effectiveness of  botanical pesticide formulations on rice bugs in rice plants. The plant material used was maja flesh, galangal, and tobacco. The dose used is 20% with a water solvent. Botanical pesticides were applied in the shelf life of 0, 1, 3, 5, 7 and 9 weeks. The results showed that a 20% dose of plant-based pesticides made by heating could kill 100% of stinky bugs if the pesticide is directly used or stored for 3 weeks. Dosage 20% of botanical pesticides made by fermentation can kill 100% rice bugs when the pesticide is used immediately or stored for 5 weeks. Vegetable pesticides from a mixture of tobacco leaves, maja flesh, and galangal made with fermentation have longer effectiveness than those made by heating.
