“…The first plant, known as the giant weed, can be found in the tropic, including Indonesia [4,5]. It can be used as an insecticide [7,8], medicinal plant [9], molluscacide, fungicide, and nematicide [10]. As ovicidal [11,12,13], oviposition deterrent [14], larvicidal and repellent [15] for insects are related to the production of secondary metabolic.…”

Farmer’s use of synthetic pesticides on rice is still high and therefore needs to be reduced. The study aims to examine the insecticidal activity of fermented C. gigantea and C. cujete extract mixture against pests and natural enemies and its impact on rice production. The extracts mixture was applied to the rice crop eight times with concentrations of 1%, 2.5%, 4.0% 5.5% and 7.5%. The results showed that all concentrations significantly reduced the S. Innotata and C. medinalis population and their damage intensity compared to the farmers’ treatment. However, these extracts did not adversely affect natural enemies, like Coccinellidae, Aranea, Zygoptera and Paederinae families, and tended to increase rice production. Therefore, these data showed that the application of fermented two-extract combinations was effective in controlling rice pests without any impact on natural enemies.

C. gigantea L. and C. cujete L. are plants that contain secondary metabolites that can act as insecticides. This study aimed to evaluate the implications of C. gigantea and C. cujete to reduce the population and intensity of attack by stem borer (S. innotata) and stink bug (L. acuta) which are the main pests of paddy plants. This study consisted of 4 treatments consisting of a mixture of C. gigantea and C. cujete extracts, C. gigantea extracts, C. cujete extracts, and control with 5 replications. The extract made by fermentation ant the extract was applied at the age of 1 month after planting with a concentration of 5% for 8 times with a frequency of 1 time a week. Observation parameters were population and attack intensity of S. innotata and L. acuta as well as natural enemy population. The results obtained were that the treatment of all extracts could reduce the population and intensity of attacks compared to the control. Treatment of the mixture of C. gigantea and C. cujete extracts can reduce the population and the intensity of attacks is higher than without the mixture. Predator is not affected by extract applications.
