[′ben·sə‚līd]
(organic chemistry)
C14H24O4NPS3 An S-(O, O-diisopropyl phosphorodithioate) ester of N-(2-mercaptoethyl)-benzenesulfonamide; an amber liquid slightly soluble in water; melting point is 34.4°C; used as a preemergent herbicide for annual grasses and for broadleaf weeds in lawns and vegetable and cotton crops.

Oxadiazon (bensulide), another organophosphate herbicide, also produced complex time-and concentration-dependent changes across all end points (Figure 2F).
At time of seeding, preemergence herbicides such as pronamide or bensulide are applied, to be activated with the initial sprinkler irrigation.
Al llevar a cabo la separacion de medias entre tratamientos por medio de la prueba de Tukey (P<0,05) se pudo observar que los tratamientos de herbicida que propiciaron sintomas muy ligeros de fitotoxicidad al cultivo de tomate de cascara de riego bajo condiciones de campo en siembra directa fue el de bensulide con un porcentaje de fitotoxicidad del 3,2%, seguido por el rimsulfuron y la trifluralina con sintomas ligeros al cultivo (7,5% en ambos casos).
Por otra parte, los tratamientos a base de trifluralina, pendimetalina, bensulide, metribuzina y flufenacet mostraron porcentajes de control de maleza del 88,2; 87,5; 85,0; 82,5 y 82,5% respectivamente (Tabla V).
Bensulide is very effective against crabgrass, but its control of another annual grass, goosegrass, is relatively poor.
Commonly used preemergence chemicals include benefin, bensulide, dithiopyr, metolachlor, oxadiazon, pendimethalin, prodiamine, and siduron.
The Phase I library included four chemicals replicated twice [3-iodo-2-propynylbutylcarbamate (IPBC), dibutyl phthalate (DBP), d-ethyl dipropylthiocarbamate (EPTC), and fenoxaprop-ethyl] and two that were replicated three times (bensulide and diclofop-methyl), and the Phase II library contained seven chemicals from the Phase I library replicated three times [allethrin, azoxystrobin, bisphenol A, oryzalin, perfluorooctane sulfonic acid (PFOS), triadimenol, and triclosan] and two additional chemicals from Phase I that were replicated six times (clo rophene and mancozeb).
Bensulide [S-(0,0-diisopropyl phosphorodithioate) ester of N-2-mercaptoethyl) benzene-sulfonamide] and oxadiazon [2-tert-butyl-4-(2,4-dichloro-5-isopropoxyphenyl)-2-1,3,4-oxadiazolin-5-one], were applied for preemergence weed control at a rate of 6.7 and 1.7 kg [ha.sup.-1] late March of 1993 and 1994.
This resulted in inclusion of the following 14 OPs: azinphosmethyl, chlorpyrifos, diazinon, dichlorovos, dimethoate, malathion, methidathion, omethoate, oxydemeton methyl, phosmet, acephate, bensulide, ethoprop, and methamidophos.
Of the eight OP pesticides remaining in the residential market and considered in the 2006 cumulative risk assessment (i.e., acephate, bensulide, dichlorvos, disulfoton, malathion, naled, tetrachlorvinphos, trichlorfon), five form DM metabolites, one forms DE metabolites, and two do not form any DAP metabolites.
Irrigation was applied when needed to provide a total of 25 to 40 mm per week, and a tank mix of 2.2 kg/ha of naptalam (2-[(1-naphthalenylamino) carbonyl] benzoic acid) and 4.4 kg/ha of bensulide (O, O-bis(1-methylethyl)-S[2-[(phenylsulfonyl) amino] ethyl] phosphorodithioate) was applied preplant for weed control.
(c) OP pesticides that do not metabolize to dialkyl phosphate compounds (e.g., bensulide, acephate) are not listed.
