  • the herbicide composition prepared in Examples 1-15 was used for field weed effect test.
  • Soil treatment Before the weeds germinate, use a hand sprayer with a water volume of 45 kg / 667m 2 , and evenly spray the soil surface.
  • Stem and leaf treatment until the weeds are in the 3-4 leaf stage, use a hand sprayer with a water volume of 30 kg / 667m 2 , and spray uniformly with the stem and leaf spray.

Abstract

La présente invention se rapporte au domaine des pesticides et concerne plus précisément une composition herbicide contenant du dichlorure de clomazone et son utilisation. La composition herbicide comprend une quantité efficace du point de vue herbicide de l'ingrédient actif A et de l'ingrédient actif B, l'ingrédient actif A étant le dichlorure de clomazone ; et l'ingrédient actif B étant choisi parmi un ou plusieurs des composés suivants et des sels/esters de ceux-ci : un inhibiteur de VLCFA, un inhibiteur de PPO, un inhibiteur de PSII, un inhibiteur d'assemblage de microtubules, un inhibiteur de HPPD, une hormone de synthèse et autres. La composition peut lutter efficacement contre les problèmes de mauvaises herbes telles que la Cardamine hirsuta, le pied-de-coq, le Monochoria vaginalis, l'Amaranthus retroflexus, les chénopodes, la Leptochloa chinensis et autres et présente des caractéristiques telles qu'un spectre herbicide expansé et une quantité d'application réduite, ainsi qu'une capacité à produire un effet synergique et à éliminer les mauvaises herbes résistantes.
