Usage

Uses

Used in Agricultural Industry:
Bensulide is used as a herbicide for preemergent control of annual grasses and broadleaf weeds in agricultural crops such as carrots, fruiting vegetables, leafy vegetables (mostly head lettuce), dry bulb vegetables (onions), cucurbits (mostly melons), and cole crops (cauliflower, cabbage, broccoli, broccolini, and broccoflower). It is also used on field-grown herbaceous plants and field-grown bulbs.
Used in Turf and Golf Courses:
Bensulide is used as a herbicide to control bluegrass, crabgrass, and other annual grasses and broadleaf weeds in agriculture crops, cotton, and turf. It is widely used on golf courses and home lawns, targeting weeds such as barnyardgrass, burning nettle, and canarygrass.
Outdoor Homeowner and Professional Use:
Products containing bensulide are intended for outdoor homeowner use on lawns and ornamentals, as well as application by professional lawn care operators to lawns, ornamentals, parks, and recreation areas.
Note: Bensulide is not approved for use in EU countries.

Potential Exposure

A selective preemergence organophosphate herbicide used to control bluegrass, crabgrass and other annual grasses and broadleaf weed s in agriculture crops, cotton and turf. It is widely used on golf courses and home lawns. Target weeds also include barnyard grass, burning nettle, and canary grass.

Carcinogenicity

Bensulide was given in the diet for 104 weeks to rats at levels to achieve doses of 0, 1, 15, or 60 mg/kg/day . No cholinergic signs were observed at any dose. Increased absolute liver weights accompanied by mild histopathological changes (hepatocyte vacuolation and eosinophilic foci) occurred at 60 mg/kg/day, but there was no evidence of carcinogenic potential. Bensulide was given in the diet for 78 weeks to mice at levels to achieve 0, 1, 50, or 200 mg/kg/day . Survival rates, clinical observations, and hematological parameters were unaffected at all doses. Decreased overall body weight gains, increased absolute and relative liver weights accompanied by histopathological changes (pale foci, cell atypia, and cell foci) occurred at 200 mg/kg/day (males only). Overall body weight gain was also reduced in males at 50 mg/kg/day, but there was no evidence of carcinogenic potential.

Shipping

UN3018 Organophosphorus pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1—Poisonous materials. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Incompatible with oxidizers; chlorates nitrates, peroxides. Decomposes slowly in light and strong UV. Corrosive to copper, aluminum, magnesium, zinc. Slowly hydrolyzes in water, releasing ammonia gas and forming acetate salts. In the presence of strong reducing agents such as hydrides, organophosphates form highly toxic and flammable phosphine gas. Contact with oxidizers can cause the release of toxic oxides of phosphorus. Stable @ 80 C for 50 hours; decomposes @ 200° C in 18 40 hours.

Waste Disposal

Destruction by alkali hydrolysis or incineration. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
