Benefin is an active ingredient in herbicides designed to control problematic annual grasses and broadleaf weeds. Benefin is primarily a pre-emergent herbicide meaning that it attacks weed seeds before they germinate in order for the product to be effective.

Benefin is also known by other names such as Balan, Balfin or its more scientific name Benfluralin. Benefin brings season long control to target weeds such as direct-seeded lettuce, established turf, seeded alfalfa, red clover, birdsfoot trefoil, and ladino clover.

What is Benefin?

Benefin (chemical name: N-Butyl-N-ethyl-a,a,a-trifluoro-2,6-dinitro-p-toluidine (56)) is a herbicide that was made to control a variety of broadleaf and grassy weeds on a variety of different landscapes. Benefin is of the class of inhibitors called dinitroanilines which inhibit cell division. Benefin is a shortened version of the name benfluralin. Benefin was first registered in the United States in 1970. 

Benefin based products come in a variety of different formulations such as emulsifiable concentrate, granules, soluble concentrate/liquid, water dispersible granules (dry flowable). Benefin can be used alone and has been manufactured in combinations with formulas such as with trifluralin and oryzalin. 

Some of the types of weed it is known to successfully control is  annual bluegrass, barnyardgrass, crabgrasses, crowfootgrass, fall panicua, foxtails, goosegrass, seedling johnsongrass, junglerice, ryegrass, sandbur, Texas panicum, carpetweed, chickweed, knotweed, lambsquarters, pigweeds, purslane, redmaids, and Florida pusley.

How Does Benefin Work?

Benefin’s mode of action is that the product inhibits cell division. The results of applying this product are very few roots emerge, and they are club shaped. As a pre-emergent herbicide, benefin is only effective before the seeds of the targeted weed have sprouted. If the problem weed is already grown, it will not harm the plant. 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. 

There are some weeds that are not detrimentally affected by the use of benefin. These include nightshade, mallonutgrass, cocklebur, groundsel, and ragweed.
