Product Description

Use on un-infested grain in any type of storage, sealed or unsealed. It is suitable for use by grain growers and grain accumulators. Thanks to the use of deltamethrin, there are no insect resistance problems. Bayer has implemented a Product Stewardship Program for K-Obiol EC with the main objective to ensure grains are only treated once. NOTE:  K-Obiol EC Combi has replaced the previous formulation - use rate and cost-of-use are unchanged. Visit the K-Obiol EC Combi section on this website.
