Benefin is an herbicide used for weed control on annual grasses and broadleaf weeds in the preemergent phase of life, meaning that it must be applied before weeds sprout in order to be effective. Benefin will not control established weeds.
A professionally formulated granular pre-emergent herbicide to control annual weeds by destroying their seeds as they germinate.
How does Benefin work? (Mode of Action)
After the initial application, benefin should be incorporated into the soil within 4 to 8 hours using equipment that breaks up the surface. Once absorbed by germinating seeds, benefin inhibits the assembly of microtubule assembly, preventing further weed growth.
Benefin is most commonly used for controlling annual grasses, broadleaf weeds, direct-seeded lettuce, seeded alfalfa, birdsfoot trefoil, red clover, established turf, ladino clover, and more.
Some weeds that are not affected by benefin include nightshade, mallonutgrass, cocklebur, groundsel, and ragweed.
Benefin presents little to no hazard to mammals and birds, but is toxic to fish. Keep out of reach of children and always read the product label before applying benefin or any other pesticide product.
