Broadleaf Weed Control With Liquid Weed Killers
Dandelion, clover and chickweed are common broadleaf weeds that homeowners generally like to get rid of. While good fertilization and mowing practices can combat most broadleaf weeds from appearing, there are times when chemical control is needed.
When using a liquid weed control product, there are two ways it can be applied. You can treat large areas using a concentrated product attached with a hose-end sprayer (might be indicated as a RTS or Ready-To-Spray) which performs the proper water-to-chemical ratio right at the sprayer. Or, you can “spot spray” individual weeds with a premixed ready-to-use (RTU) product or mix a concentrated product in a tank sprayer. When reviewing product labels, look for labels that say “For Lawns” or “Lawn Weed Killer”. Products that say “Weed & Grass Killer” will also kill your lawn. Do NOT buy anything that contains glyphosate if you want to kill weeds in your lawn and NOT the grass.
The most common lawn weed control products contain three chemicals: 2,4-D, Dicamba and Mecoprop (MCPP). These products all basically work the same way by disrupting normal plant growth leading to death. When combined, they are more effective and control a larger variety of weeds.
Season Long Weed Control: For those that want long-lasting control of broadleaf weeds, you can use BioAdvanced™ Season Long Weed Control for Lawns. This product not only contains the three chemicals mentioned above, it also contains the pre-emergent herbicide Isoxaben. With this addition, it will kill over 200 broadleaf weeds PLUS you are preventing any new germination of listed weeds for up to 6 months.
Crabgrass Control: If you are looking to kill broadleaf weeds AND kill crabgrass that has come up in your lawn, looks for a product that contains Quinclorac. It will generally say on the packaging “Lawn Weed Control plus Crabgrass” such as Ortho® Weed B Gone Plus Crabgrass or BioAdvanced Lawn Weed and Crabgrass Killer.
When chemical control is needed to control weeds, only buy a product that will get the job done. For large areas, a broadcast application is probably the best. For smaller areas, spot spray. Many products available today are combined to control not only weeds but hard-to-control grasses such as nutsedge or crabgrass. If you don’t have these issues, just get the basic lawn weed killer. People and pets can return to the treated area when it is dry. Always read and follow label instructions.
