除草剂

Penoxsulam is ramping up well, the aminopyralid launch has been excellent, we're on target for our pyroxsulam project RTO in 2007 - and we made good progress on our goals of aggressive transition to our proprietary traits in corn.

比如：除草剂五氟磺草胺的市场效应表现良好，而氯氨吡啶酸这种除草剂在投入市场后，也反应热烈。在2007年度目标里，我们集中开发项目产品：蓄热式氧化器；而且，在专利谷物的快速转型目标中，我们也向前迈出了一大步。

It's soil, however, after its problems, the crop was phytotoxicity very concern, according to chlorine sulfonylurea herbicide easily after long after stubbly maize produced in the problem, residual phytotoxicity chose herbicides security agents Ⅰ compounds, N - methylene chloride acetyl groups - 5-2 - diethyl - propyl arene pbo.

它的土壤残留问题及其对后茬作物的药害影响，一直是人们极为关注的问题，故本文针对除草剂氯磺隆使用后易对后茬玉米产生残留药害的问题，选择了除草剂安全剂化合物Ⅰ：N-二氯乙酰基-5-乙基-2-丙基-1，3-恶唑烷。

Topological indexes of A , B , C and D were all obtained from the different combination of topological vertex degree. A QSAR equation for this series of compounds was established based on the multi-linear regression method and a new group of autocorrelation topological indexes. The results showed that the biological activity is linearly correlated with the volume and branching size of the quinclorac derivatives. Finally, new herbicide was designed based on all QSAR results.

针对应用经典结构参数和量子化学参数得出的结果不够理想的问题，对点价自相关拓扑指数进行了研究，建立了一组新型的点价自相关拓扑指数A、B、C、D；首次将该指数用于除草剂氯喹酸酯类化合物的定量构效关系研究中，建立了很好的定量构效关系方程，综合分析所有的QSAR结果设计出了潜在的新型除草剂氯喹酸烯丙酯。

The chemical weedicide can weed with high efficiency while the extensive spraying causes high cost and the destruction of entironment. Variable rate spraying was presented against these disadvantages.

虽然使用化学除草剂可以高效地进行除草，但由于化学除草剂所采用的普遍方式为粗放式喷洒，不仅浪费大，而且造成了生态环境的破坏，针对这一弊端，提出了变量喷洒。

2 To kill weed which may sprawl rampantly among crops in the first several years, effective weedicide is needed to play the same role as ploughing fields does to eliminate weed.

sprawl：肢；懒散地伸开；蔓延；rampant：蔓生的；无约束的；plough：=plow 犁在最初的几年里，杂草可能在农作物中蔓延滋生，为了消灭这些杂草，需要有效的除草剂，发挥为了消灭这些为了消灭这杂草，需要有效的除草剂，发挥与耕地同样的消灭杂草的作用。

In this study, differences among tolerant capabilities of three species of nitrogen-fixation cyanobacteria (Anabaena azollae, Anabaena flos-aquae, Anabaena azotic) to two new sulfonylurea (Monosulfuron and Monosulfuron ester) were studied, which could be used to further explain the resistant mechanism to sulfonylurea herbicides and how these herbicides take effect.

本文以满江红鱼腥藻、固氮鱼腥藻及水华鱼腥藻为代表，利用环境毒理学的研究手段，通过研究3种固氮蓝藻对2种磺酰脲类除草剂---单嘧磺隆、单嘧磺酯的耐药性差异来揭示对磺酰脲类除草剂产生抗药性和耐药性的机理。

To transfer bar gene into other variety by backcrossing is a simple and effective approach to getting new transgenic material resistant to herbicide"Basta".

通过回交将抗Basta除草剂的bar基因转育到其它品种，是获得新的抗除草剂转基因材料的一种简便有效的方法。

Objective: To observe the effect of the herbicide butachlor on myocardial contracts dint and myocardial enzymogram of Bufo bufo gargarizans, and to study physiological toxicity of herbicide butachlor on myocardial of Bufo bufo gargarizans.

目的：观察除草剂丁草胺对蟾蜍心肌收缩力和心肌酶谱的影响，探讨除草剂丁草胺对蟾蜍心肌的生理毒性。

The major factors for callus induction, differentiation, and Agrobacterum-mediated transformation were investigated in the current paper, using the creeping stem nodes of Cynodon dactylon as the original materials.

以主要暖季型草坪草狗牙根的匍匐茎节为试验材料，对其愈伤组织的诱导、分化以及农杆菌介导转化的关键因子进行优化，以此为基础将除草剂抗性基因bar导入狗牙根中，并对抗除草剂狗牙根的推广应用作了探讨。

The bacterial, mammalian and plant cytochrome P450s involved in metabolism of herbicides are reviewed in this paper. The action modes of cytochrome P450s on herbicides including dealkylation, ring-methyl hydroxylation and aromatic ring hydroxylation etc are summarized.

本文综述了代谢除草剂的细菌、哺乳动物和植物细胞色素P450酶系，概述了细胞色素P450酶系参与除草剂代谢的作用方式：脱烷基化作用、环甲基化羟基化作用和芳环的羟基化作用等。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
