Abstract
The sustainability of cocoa production in Indonesia is faced with the problem of the cocoa pod borer (Theobroma cacao L.). In an effort to control the main pests on cocoa plants, various techniques can be used, namely control with the use of natural insecticides and control by technical culture in the form of pruning. Natural insecticide is an insecticide whose basic ingredients come from plants that are easilybiodegradablein nature, so they do not pollute the environment and are relatively safe for humans and livestock, because the residue is easily lost. Pruning is the act of removing part of the plant organs in the form of branches, twigs and leaves with the aim of obtaining good cocoa plant branches, regulating the distribution of production branches and leaves so that they are evenly distributed, removing unwanted plant parts, stimulating the plants to grow. form new organs, reduce the risk of pest and disease attacks, and increase the ability of plants to form fruit. The purpose of this study was to determine the response of the application of botanical insecticides and pruning to the control of the cocoa pod borer (Theobroma cacao L.). The experimental design used a non-factorial randomized block design consisting of 7 treatments. The treatment of vegetable insecticides consisted of 4 levels, namely I0 (Without insecticide = Control), I1 (vegetable insecticide made from srikaya seeds at a dose of 250 ml/liter of water), I2 (vegetable insecticide made from tuba root with a dose of 250 ml/liter water), I3 (vegetable insecticide made from tobacco leaves at a dose of 250 ml/liter of water). The pruning treatment consisted of 3 levels, namely I4 (Without Pruning (Control), I5 (Pruning Interval 7 days after the study) and I6 (Pruning Interval 14 days after the study). Observations consisted of attack intensity, level of damage caused by PBK attack, attack index and production Control of the cocoa pod borer by pruning and botanical insecticides on cocoa plants showed a significant effect on the parameters of attack intensity and level of damage at the age of 6 weeks, and the attack index at the age of 12 weeks. 2 msp, 4 msp, 8 msp, 10 msp, 12 msp, and the parameters of the level of damage at the age of 2 msp, 4 msp, 8 msp, 10 msp, 12 msp and the plant production parameters at the age of 12 msp showed no significant effect.
