Product Overview

Trimec Crabgrass Concentrate is specially designed to control more than 200 common broadleaf weeds. Contains three active ingredients that are highly effective in eliminating unwanted weeds on lawns. It also targets emerged grassy weeds such as Foxtail, Signalgrass, and Crabgrass. The Trimec Crabgrass Concentrate features a liquid concentrate formula that powerfully controls broadleaf weeds including aster, burclover, fiddleneck, dandelion, cockle, henbit, morning glory, musk thistle, mallow, poison ivy, poison oak, pigweed, ragweed, and plantain. Proven to be long-lasting and it is 6 to 8 hours rainfast. Ideal to apply using a hose-end sprayer, a tow-behind sprayer, and a pump-up sprayer. Reapplication may be needed after 21 days and it is highly suggested to mow 2 to 3 days before applying the herbicide or after the application. For safety, allow people and pets to enter the treated area once the spray has completely dried. Sold in a 32 oz bottle that can cover up to 5,000 square feet.
