Abstract
The main enemy in rice production is the attack of stinky bugs, brown planthoppers, grasshoppers, ladybugs, aphids and others. This attack inhibits the growth of rice plants, thereby reducing production or even thwarting the harvest. Chemical pesticide application is able to reduce pests and diseases. However, the long-term use of chemical pesticides can disrupt the ecosystem. This study aims to study the application of plant-based pesticide to the presence of pests and predatory insects for ciherang rice plants. The research was begun with the preparation of plant-based pesticide from lemon grass extract obtained by mixing citronella with water at a weight ratio of 2:1. The extract was mixed with water at ratio of 1 liter for 50 ml of citronella extract. The application of plant-based pesticide was carried out by spraying 21-DAP (day after planting) rice plants at two plots sizing 400 m2 each. The types and numbers of pests and predatory insects were observed before and every pesticide application. Spraying and observation were carried out weekly for 5 weeks starting at 21 DAP. The results showed a decrease of insect in experimental plots A and B after the application of pesticide. After the fourth application, only one type of insect (green grasshopper) was found in plot A and no insect were found in plot B. However, four types of insects were found in the control plot. The application of citronella-based pesticide did not disturb the population of predatory insects that were still found in plot A and B (8 tails) at the end of the observation.
