展望将来的除草剂的特点无论在什么时代,对于除草剂的性质和特点,都希望它既对杂草高效,又对作物安全,既不导致在作物内残留和环境污染方面的问题,又要价格便宜,施用方便。向这些方面的全面努力,是今后发展除草剂的目标。另一方面,如果从现实存在的问题出发,首先必须抓住目前除草剂中存在的药害以及对鱼类的毒害问题。特别是药害问题,随着耕作技术的改革,有必要引起足够的重视。由联合收割机进行的生稻草施用法,促进了土壤还原,但这样在通常条件下不产生药害的除草剂, Looking forward to the future characteristics of herbicides No matter in what era, for the nature and characteristics of herbicides, it is hoped that it is both highly effective weed and crop safety, neither causing residue in the crop and environmental pollution problems, but also Cheap, easy to apply. The overall efforts toward these areas are the goal of developing herbicides in the future. On the other hand, if we start from the real problems, we must first grasp the current phytotoxicity in the herbicide and its toxicity to fish. In particular, the issue of drug injury, with the reform of farming techniques, it is necessary to pay enough attention. The straw application method by a combine harvester promotes soil reduction, but the herbicide which does not produce phytotoxicity under the usual conditions,
