Uses and applications
What the substance is used for, by industry and function
For the control of undesirable grasses in lawns and broadleaf weeds.
A selective compound applied preemergence. It must be applied to soil before weeds emerge. Batasan for dichondra and grass lawns including seasonal control of crabgrass and annual bluegrass. Prefar for carrots, cole crops, cucurbits, vegetables (leafy, dry bulb, fruiting).
Betasan is registered for control of... redroot, pigweed, watergrass, lambsquarters, shepherdspurse, goosegrass, and deadnettle in grass and dichondra lawns.
Use classes: Herbicides.
Functional uses
- Biocide
How it is made
A mixture of 13.2 grams (0.06 mol) of N-(beta-chloroethyl)-benzene sulfonamide, 25.2 grams (0.1 mol) of potassium-diisopropyl dithiophosphate and 100 ml of methyl ethyl ketone yielded after 4 hour reflux period, 20.8 grams (88% theory) of viscous product.
Bensulide is produced by reaction of O,O-diisopropylphosphorodithioate with N-chloroethylbenzene sulfonamide.
