The proponents of ge rice say that yields of the crop are 7 % to 15 % higher than usual and it uses fewer agrochemicals , which will improve the environment , lower prices and in crease profits 基改米的支持者表示，基改米的产量比普通稻种高出7到15个百分点，所需的化学农药、杀虫剂也较少，因此可以减少对环境的伤害、压低米价，并增加农民收益。
We can ' t continue to indefinitely expand our old practices ? of chemical use , of water diversion , of plowing wild lands and converting them to farms , of nonagricultural sprawl and of the production of industrial waste 我们不能永无止境继续耍我们的老把戏：使用化学农药、引水灌溉、开垦野地转做农田，以及非关农业的土地利用，例如开发工业区与储存工业废料。
This paper deals with some important principles of using agricultural chemicals considering environmental security is concerned , and also suggests specific indexes of appraising the effect of chemical use on natural environment and the scientific appraising procedure 本文主要讲述了化学农药的投放使用针对环境所提出的重要原则，并提出了评价农药对生态环境安全性的具体指标以及科学的环境评价程序。
There are some serious influence on development of agriculture and economy in china by unreasonable application of pesticide , such as improvement of the living standard , foreign trade of agricultural by - products , development of greening agriculture 摘要化学农药的不合理使用，使得农药残留对我国农业和经济发展造成了严重的影响，主要表现在：影响到人民生活质量；限制了我国农副产品的对外贸易；阻碍我国绿色农业的发展。
This paper write a representative failing example of carrying " safety vegetable " into effect for " green food movement " existing many disadvantages that it is difficult to decrease pesticide remain any more , the writer put emphases on new situation of farming , physics and biology prevention and cure in planting tea . vegetable orange , aiming at bestowing lesser chemistry pesticide as possible , and explain pesticide that general plant protection station of zhejiang province recommend to use 文中还有一个实施“放心菜”工程失败的典型例子。由于“绿色农产品行动”还存在一些难以使农产品农药残留下降的缺点，作者重点介绍了茶叶、蔬菜和柑桔生产过程中农业防治、物理防治、生物防治的新情况，目的是尽量少使用化学农药，并对浙江省植物保护总站推荐使用的农药作了简介。
This article sums up the things and the actuality about in my province . on the base of this , the article applies dephi method to forecast the development of the biology pesticide industry in my province for the five years . the result shows that it will take on trend as follows : it is important for the biology pesticide in industry in the 21 century . develop the biology pesticide as well as the chemical pesticide it is little poison and high effect to realize the superiority each other 预测结果表明，我省生物农药产业发展方向将呈现如下趋势： 21世纪生物农药在农药产业中位居重要地位；协调发展生物农药和低毒高效化学农药，实现优势互补；除草剂的发展将呈现最旺的势头；杀菌剂的市场前景良好；三大类生物农药比例更趋合理，同时将会加强转基因抗性作物产品的开发与应用。
