Definitions

  • the present invention relates to a novel acetylene derivative and a herbicide using the same. More specifically, the present invention provides an acetylene derivative capable of controlling a wide range of field weeds at a low dose without causing phytotoxicity to field-cultivated crops such as corn, and an acetylene derivative containing the acetylene derivative as an active ingredient. It relates to herbicides. Background art
  • Herbicides are extremely important drugs for labor saving in weed control and for improving the productivity of agricultural and horticultural crops.Therefore, research and development of herbicides has been actively carried out for many years, and a wide variety of chemicals are currently in practical use. ing. Therefore, even today, the development of new drugs with even more excellent herbicidal properties, especially those that can control only the target weeds at low doses without causing phytotoxicity to cultivated crops, has been developed. It is desired.
  • Atrazine and the acid-based herbicides alaclor (a1 achlor) and metolachlor have been used, but atrazine has low activity against grass weeds. Conversely, it has low activity against broadleaf weeds. Therefore, it is currently difficult to control gramineous and broadleaf weeds at once with a single agent. In addition, these herbicides require high doses and are not preferred on environmental issues.
