BENSULIDE Chemical Properties,Uses,Production
Chemical Properties
Bensulide is and amber, viscous liquid, or forms colorless or white crystalline solid below 34.4 C. Combustible. Commercial product is available as an emulsifiable concentrate.
Uses
Bensulide is an herbicide used for preemergent control of annual grasses and broadleaf weeds in agricultural crops (60–65% of all use). Current registered use sites are carrots, fruiting vegetables, leafy vegetables (mostly head lettuce), dry bulb vegetables (onions), cucurbits (mostly melons), and cole crops (cauliflower, cabbage, broccoli, broccolini, and broccoflower). Bensulide can also be used on field-grown herbaceous plants and field-grownbulbs. Products containing bensulide are intended for outdoor homeowner use on lawns and ornamentals, and application by professional lawn care operators to lawns, ornamentals, parks, and recreation areas.
Hazard
Highly toxic, cholinesterase inhibitor. Use may be restricted.
Agricultural Uses
Herbicide: A selective pre-emergence herbicide used 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. Target weeds also include barnyardgrass, burning nettle and canarygrass. 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.
