|
| Liberty plus atrazine will control or suppress some perennial weeds, including dandelion, Canada thistle, Jerusalem artichoke, and wirestem muhly. |
|
| The company documents show that, while Hayes was studying atrazine, Syngenta was studying him, as he had long suspected. |
|
| Pesticides, such as DDT, atrazine, chlordane and lindane, and industrial by-products like dioxin, furans and PCBs, have been identified as endocrine disruptors. |
|
| The researchers also gathered evidence that atrazine exposure affected the hypothalamic-pituitary-thyroid axis in the tadpoles. |
|
| This is most clearly the case for atrazine, which is no longer registered in Germany, Italy and the Netherlands. |
|
| Furthermore, the impact of any de-registration of atrazine in France on the parties' market position must not be overstated. |
|
| The Committee was asked to comment on the aspects of possible contamination of groundwater by atrazine. |
|
| Terbuthylazine has a similar spectrum of control as atrazine but has weaker activity. |
|
|
|
| The researchers found that atrazine affected the frogs through multiple pathways. |
|
| Other atrazine formulations will require a rate calculation adjustment according to percent of active ingredient. |
|
| At low doses, atrazine induces aromatase and estrogen expression. |
|
| No unusually high levels of pesticides and metals or even oil and grease were detected from the run-off, although the common herbicide atrazine has been detected twice. |
|
| Bioassays with lettuce and cucumber seedlings showed that simazine, a triazine herbicide related to atrazine, can persist in soils and cause subsequent replanting problems. |
|
| Another scientist shows viewers a frog, exposed to atrazine in the agricultural runoff of farms in Salinas, Calif. |
|
| Effect of HCH, carbaryl, benomyl and atrazine on the hydrogenase activity in a flooded soil. |
|
| Scientists have yet to determine the potential implications of wide-scale atrazine exposure on global amphibian populations and whether there are population-level effects. |
|
| Summary: The petitioner is concerned about Canada's regulation of the herbicide atrazine in light of a scientific study that, the petitioner claims, shows adverse effects on amphibian populations. |
|
| Even though terbuthylazine is by itself a rather old compound and off-patent, it was introduced in the maize market only in the early 90s exactly because atrazine was banned in Germany and Italy. |
|
| It is indeed the case that atrazine has been deregistered in Germany, Italy and the Netherlands because of its rather unfavourable environmental properties. |
|
| For example, the chlorinated herbicide atrazine is gradually degraded by aerobic microorganisms through a variety of pathways involving intermediate products. |
|
| However, atrazine is known to have indirect and sublethal effects that were not measured in the experiment. |
|
| One of his first graduate students, Nigel Noriega, who runs an organization devoted to conserving tropical forests, told me that he was still recovering from the experience of his atrazine research, a decade before. |
|
| Only atrazine concentrations occasionally exceed the criteria for the protection of aquatic life, in summer, at the mouths of certain rivers, including the Yamaska. |
|
| An example of such an approach would be to offer a brand containing acetochlor and atrazine to one group of distributors and a brand containing metolochlor and atrazine to another. |
|
| As far as product mixes of other active substances with atrazine is concerned, the de-registration of atrazine would be of less importance, given that there is an acceptable substitute in the form of terbuthylazine. |
|
| So my own schooling went back to the late 1950s and early 1960s, and at that time they were beginning to expound on all these synthetic chemicals like simazine, atrazine, and so forth, that are two a penny today. |
|
| Furthermore, their portfolio will contain at least four other important active substances, namely pyridate, prosulfuron, atrazine and terbuthylazine. |
|
| For tank mixtures, add either atrazine or Marksman Herbicide according to instructions on the product label, and then add Glyfos Herbicide according to instructions on this label. |
|
|
|
| In order to remove the overlap in the segment of post-emergence grass control in France, the parties have offered to stop commercialising straight atrazine in France and to hand back related trade names to the owners. |
|
| The organic phase was composed of 100 mg of polymer, 30 mL of organic solvent, 200 mg of oil, 40 mg of sorbitan monostearate surfactant, and 10 mg of atrazine. |
|
| Detailed analysis of bound atrazine residues in soil demonstrated that most of the residues were in the finest soil fraction that contained humified organic matter. |
|
| Half-lives of PSII herbicides ametryn, atrazine, diuron, hexazinone and tebuthiuron were consistently greater than a year, indicating high persistence. |
|
| Effects of atrazine on embryos, larvae, and adults of anuran amphibians. |
|
| The pesticide atrazine acted synergistically with predation to affect survival, reproduction, and immunity for individuals in the snail species Physa gyrina. |
|
| Atrazine is a potent endocrine disrupter that chemically castrates and feminizes amphibians and other wildlife. |
|
| Atrazine is an herbicide widely used to control weeds in Midwest corn and soybean fields. |
|
| Atrazine is mainly applied to corn and soybean crops, but is also used on sorghum, sugarcane, pineapple, turf grass, and Christmas tree farms. |
|
| Atrazine and simazine are corn herbicides used by growers worldwide. |
|
| Atrazine and its byproducts are known to be relatively persistent in the environment, potentially finding their way into water supplies. |
