Chemical Action and Usages: Trimec is a selective herbicide for the control of a wide range of broad-leafed weeds including dandelion, plantains, chickweed, clover, henbit, spurge, wild onion and more in established lawns without harming the turf grass. It may also be used for broadleaf weed control in other non-crop areas of the landscape. Trimec is a combination of 2, 4-D, Mecoprop and Dicamba. The addition of Quinclorac in the products listed above adds post emergence control of some grassy weeds including crabgrass (large & smooth) and foxtail (green, yellow & giant). Additionally, Quinclorac also controls certain harder to control broad leafed weeds including clovers, ground ivy and violets. Products containing Carfentrazone will enhance broad leaf weed control in the cool weather of early spring and fall but will not control grassy weeds. All of these chemicals are absorbed through the leaves and translocated throughout the plant. Most of these products are available in liquid concentrate, RTU & RTS sprays and in granular forms as a weed killer alone or in combination with lawn fertilizer (Weed and Feed). For control of nut sedges such as yellow nutsedge, see the information on Specialty - Nut-Sedge and for better control of clover, wild violets, poison ivy and other hard to control broad-leafs see the information on Specialty - Broadleaves. Spot spraying of weeds helps protect the environment and uses less chemical.
Cautions/Instructions: Read the label carefully of the brand and formulation you have selected. Apply these products according to the directions on the label. Avoid spraying when air temperatures are above 90 degrees F. Do not apply spray products in windy conditions as damage to desirable vegetation may result. Consult individual product label to determine the amount of time needed between application and when rain or irrigation is expected. Do not use grass clippings in your vegetable garden from turf grass sprayed with these products. Do not apply directly to areas where surface water is present. The dicamba in some of these products may be absorbed by surface and shallow roots and cause significant damage to desirable trees and shrubs.
Toxicity: Low to moderate toxicity to humans (possible eye, skin and mucous membrane irritation), pets and birds. Toxic to fish and aquatic invertebrates. Low toxicity to bees.
