That is, a chemical solution prepared by diluting the emulsion prepared according to Example 27 with water was sprayed onto the soil surface at a rate of 100 liters per 10 ares. When the application amount of the active ingredient was converted, it was equivalent to 120 g per 10 ares.
  • Field soil (alluvial loam) was placed in unglazed pots, 1 / 10,000 a yard. Put the seeds of each crop (5 soybeans, 5 corns, 10 sugar beet, 10 rapeseed, 10 wheat and 10 oats) in separate pots Seeding was performed and the surface layer was lightly pressed. One day after sowing, weeding treatment was performed. That is, a chemical solution prepared by diluting the emulsion prepared according to Example 27 with water was sprayed onto the soil surface at a ratio of 100 liters per 10 aar. Converted amount of active ingredient applied is 10 A This was equivalent to 120 g.

Abstract

Nouveaux dérivés d'isoxazolinone représentés par la formule générale suivante (I) qu'on peut utiliser en tant qu'herbicides pour les rizières et les hautes terres, qui exercent une activité herbicide élevée et présentent une sélectivité importante de l'activité herbicide, ainsi qu'une rémanence excellente de cette activité, dans laquelle R1 représente alkyle inférieur ou hydrogène; R2 représente alkyle inférieur ou un analogue; R3 représente phényle mono-, di- ou tri-halogéné, un autre phényle substitué, 2-pyridyle, 2-pyridyle halogéné ou analogues; Q représente phényle substitué ou insubstitué, benzyle, un groupe hétérocyclique, un groupe méthyle substitué par un hétérocycle, alkoxycarbonyle ou carbamoyle N,N-disubstitué. La plupart de ces nouveaux dérivés peuvent détruire Echinochloa oryzicola et d'autres plantes nuisibles principales, en totalité ou presque complètement, même avec une faible dose, ne détériorent pas le riz brut, l'orge ou les plantes céréalières et présentent une activité herbicide résiduelle pendant une durée prolongée contre les plantes nuisibles poussant dans les rizières et dans les hautes terres.
