• METHOD FOR PREPARING EMULSIFIABLE SOLID AGROCHEMICAL COMPOSITION CONTAINING INORGANIC SALT
  申请人：Kyung Nong Corporation

  公开号：EP2868195A1

  公开（公告）日：2015-05-06

  The present invention relates to a method for preparing an emulsifiable solid agrochemical composition which contains an inorganic salt and which can be used as an agrochemical emulsion. The preparation method according to the present invention has the advantage that, because there is no need for a step of heating and evaporating a solvent or water, it is possible to use a surfactant or active ingredient that has a low boiling point or breaks down drastically at a high temperature, and, due to the solid-phase form, it is possible to minimize the amount that sticks to a container as there is no need to use a special synthetic resin or glass bottle that entails high packaging costs. Also, a granular emulsifier (EG) or a powdery emulsifier (EP) produced by means of the method according to the present invention can be further diluted in water before use so as to form common emulsion (EC) emulsified particles (0.1 µm to 100 µm) to transparent microemulsion particles (0.001 µm to 1 µm or 1 nm to 1000 nm), and thus the emulsion size can be freely modified so as to maximise the activity of the agrochemical component in accordance with the characteristics of a crop or an insect pest.

  本发明涉及一种可乳化的固体农用化学品组合物的制备方法，该组合物含有一种无机盐，可用作农用化学品乳剂。根据本发明的制备方法具有以下优点：由于不需要加热和蒸发溶剂或水的步骤，因此可以使用低沸点或在高温下急剧分解的表面活性剂或活性成分；由于是固相形式，因此可以最大限度地减少粘附在容器上的量，因为不需要使用需要高昂包装成本的特殊合成树脂或玻璃瓶。此外，根据本发明的方法生产的颗粒状乳化剂（EG）或粉末状乳化剂（EP）在使用前可进一步用水稀释，以形成普通乳液（EC）乳化颗粒（0.1 微米至 100 微米）到透明微乳液颗粒（0.001 微米至 1 微米或 1 纳米至 1000 纳米），因此可根据作物或害虫的特性自由改变乳液大小，以最大限度地提高农用化学品成分的活性。
• Herbicide resistant rice

  Rice plants are disclosed with multiple sources of resistance to herbicides that normally inhibit a plant's acetohydroxyacid synthase (AHAS) enzyme. Besides controlling red rice, many AHAS-inhibiting herbicides also effectively control other weeds that are common in rice fields. Several of these herbicides have residual activity, so that one treatment can control both existing weeds and weeds that sprout later. With effective residual activity against red rice and other weeds, rice producers now have a weed control system superior to those that are currently available commercially.

  据披露，水稻植物对通常抑制植物乙酰羟基酸合成酶（AHAS）的除草剂具有多种抗药性。除控制红稻外，许多抑制 AHAS 的除草剂还能有效控制稻田中常见的其他杂草。其中有几种除草剂具有残留活性，因此一次处理就能同时控制现有杂草和以后萌发的杂草。由于对红稻和其他杂草具有有效的残留活性，水稻生产者现在拥有了比目前市售除草剂更优越的除草系统。
