The use of botanical insecticide based on local resources to increase swamp rice yield in South Kalimantan, Indonesia

Abstract

The use of botanical insecticide is one of the ways to reduce the negative impact on the agricultural environment due to chemical insecticide applications. Some plants have been identified as botanical insecticide such as Azadirachta indica (Neem), Swietenia mahagoni (Mahagony), Aegle marmelos (Maja fruit), etc. This study was conducted as a part of the demonstration farm located in the swamp rice field in South Kalimantan. The objective of the study was to increase the swamp rice yield by controlling plant pests and disease based on local resources environment friendly. The plot experiment was arranged in a randomized block design with three treatments and six replications and the plot size wase 1.000 m2. The treatments consisted of fully RAISA technology (T1 treatment), RAISA + IAERI botanical insecticide (T2 treatment), and RAISA + Galam botanical insecticide (T3 treatment). The result showed that the highest yield rice was produced in T2 treatment (6.5 t ha-1 unhusked dry rice), then T3 and T1 treatments were 5.5 and 5.1 t ha-1 unhusked dry rice, respectively. The highest amount of insect was found at T1 treatment, followed T2 and T3 treatments, respectively.
