He and co-researchers have shown that anaerobic bacteria can rapidly degrade trifluralin
if the soils contain clay minerals and are soggy, even if just for a few days.
([alpha],[alpha],[alpha]-trifluoro-2,6dinitro-N,N-dipropyl-p-toluidine; 1.12 kg a.i.
For example, Roundup Ready soybeans have negatively affected our trifluralin
business but offer opportunities for our recently registered Arrow brand clethodim.
In practice, 32 substances are proposed as priority substances under the Framework Directive, divided into three groups:- 11 substances are proposed as "dangerous priority substances": brominated diphenylether, cadmium, chloroalcanes C10-13, hexachlorobenzene, hexachlorobutadiene, hexachlorocyclohexane; mercury, nonylphenols, poly-aromatic hydrocarbons(PAH) (pentachlorobenzene, tributytin compounds- 11 others as priority substances on appraisal: anthracene, atrazine, chlorpyrifos, di(2-ethylhexyl)phtalate (DEHP), endosulfan, lead, naphthalene, octylphenols, pentachlorophenol, trichlorobenzene, trifluralin
. The final decision concerning the status of the second list will be approved during the review of the list of priority substances.
ARS scientists also found that bacteria called fluorescent pseudomonads can degrade metolachlor, propanil and trifluralin
-- three commonly used herbicides in the MSEA area.
Indeed, companies like Sanachem and Fine Chemicals Corporation have had considerable success in exporting fine chemicals such as the fungicide trifluralin
and the anti-cancer agent vinblastine.
It consists of a geotextile fabric that has controlled-release nodules containing trifluralin
. It diverts roots away from sidewalks and streets without harming the tree.
: The dinitroaniline herbicide trifluralin
(N,N-di-n-propyl, 2,6-dinitro 4-trifluoromethyl anilin) is peculiar in that it is not readily taken up by plants, nor is it susceptible to biological degradation.
(2005) found that Trifluralin
's absorption was enhanced in the presence of oleic acid whereas the greatest absorption of atrazine and alachlor occurred with palmitic acid and the control media, respectively.
For the experiment with 7 herbicides applied in pre-emergence, atrazine (D = 2500 g [ha.sup.-1]), atrazine + mesotrione (D = 1200 + 120 g [ha.sup.-1]), atrazine + simazine (D = 250 + 250 g [ha.sup.-1]), isoxaflutole (D = 60 g [ha.sup.-1]), pendimenthalin (D = 1500 g [ha.sup.-1]), trifluralin
(D = 2400 g [ha.sup.-1]) e s-metolachlor (D = 1400 g [ha.sup.-1]) were evaluted.
Relative efficacy of trifluralin
and imazethapyr for weed control in lucerne (Medicago sativa L.).
