Sims is helping fill the information gap with studies of bacteria that degrade dinitroaniline herbicides like trifluralin
, which kills annual grasses and some broadleaf weeds.

In a study with selectivity of residual herbicides to common bean, the selectivity level of dimethenamid and s-metolachlor varied according to the applied dose, while the herbicides pendimethalin and trifluralin
did not change.
Another herbicide that presents difficulty to transpose from the sugarcane straw to the soil is trifluralin
. This product was not detected in the soil under mulch conditions, even after a rainfall of 20mm applied 24 hours after application of the product on the field, unlike what was observed with atrazine in the study of RODRIGUES et al.
reduced maternal weight gain, in agreement to previous findings for Trifluralin
treated rats and rabbits (BYRD et al., 1995).
Effects of the pesticides carbofuran, chlorpyrifos, dimethoate, lindane, triallate, trifluralin
, 2,4-D, and pentachlorophenol on the metabolic endocrine and reproductive endocrine system in ewes.
To maintain the planting beds through the summer months, drip irrigation tubing was maintained and flushed with sulfuric acid ([H.sub.2]S[O.sub.4]) [General Chemical, Syracuse, New York) twice a month, and plots were irrigated once a week (unless it rained) and kept weed-free using herbicides including glyphosate and Trifluralin
, Treflan[R] EC, Monterey chemical company, Fresno, California.
(2007b) identificaram a seletividade a mamoneira dos herbicidas residuais pendimethalin, alachlor + pendimethalin e alachlor + trifluralin
em aplicacoes de preplantio incorporado e de clomazone e clomazone + trifluralin
aplicados em pre-emergencia.
The purpose of this study was to evaluate the effect of commonly used pesticides such as Pendimethaline, Trifluralin
, Glyphosphate, 2, 4-D, and MCPA (Chwastox) on microbial activities in soil.
Weed control was done chemically pre-planting by incorporation trifluralin
450 EC under 3 L [ha.sup.-1] dose and thirty days after plant emergence a hoed was done.
Austin, TX, May 06, 2010 --(PR.com)-- Bioo Scientific today announced the availability of its MaxSignal[R] Trifluralin
Studies on analytical methods for Trifluralin
determination, metabolism in animals, plants and fish, degradation in soil, photodegradation, adsorption to soil, volatilization, persistence in fields, residues in agricultural crops and river water are briefly reviewed .
