Rainnil 5SC is a broad-spectrum systemic insecticide and termiticide produced by Rainbow, formulated to control a wide range of agricultural and structural pests. It is widely used in Malaysia as a more affordable alternative to brands like Regent 50 SC, as it contains the same active ingredient.
Product Composition and Mechanism
- Active Ingredient: Contains Fipronil 5.0% w/w.
- Chemical Group: Belongs to the phenylpyrazole family (IRAC Group 2B).
- Mode of Action: It works through contact and stomach poisoning. As a non-repellent chemical, social insects like termites and ants unknowingly carry the toxin back to their colonies, leading to total nest elimination.
- Formulation: It is a Suspension Concentrate (SC), which is typically low-odor and leaves a long-lasting residual effect on treated surfaces.
