Rainbow COLAM ZC is a broad-spectrum, pre-mixed insecticide used in Malaysia to control a variety of sucking and chewing pests. It is commonly considered a high-performance alternative to Syngenta Alika ZC, as it shares the same active ingredients and formulation style.
Product Composition and Mechanism
- Active Ingredients: Contains Thiamethoxam 12.62% w/w and Lambda-cyhalothrin 9.49% w/w.
