REMEDIASI RESIDU INSEKTISIDA KLORPIRIFOS PADA PERTANAMAN CABAI MERAH (Capsicum annum L.) DI TANAH TEKSTUR RINGAN DAN TEKSTUR BERAT

Chlorpyrifos is widely used by farmers as a contact poison to control leaf and fruit pests in red chilies. Chlorpyrifos is very toxic to the environment and to living things, although it is easily degraded and has a short half-life. Remediation materials in the form of activated charcoal, biochar, and microbial consortium are effective remediation technologies to reduce insecticide residues. Each compound has different characteristics based on the type and texture of the soil. Research with the aim of determining the ability of remediation agents in reducing chlorpyrifos insecticide residues was carried out in the screen house of the Agricultural Environment Research Institute between May-November 2017. The results showed that the effectiveness of reducing chlorpyrifos residue in the soil was different according to its texture. Application of 2 l / ha of consortium microbes was effective in lowered chlorpyrifos residue in lightweight-texture soils, while biochar-coated urea was effective in reducing chlorpyrifos residues in weight-textured soils. Urea coated with activated charcoal showed relatively stable red chilli yields in the two types of soil textures.
