The invention discloses a
benzobicyclon-containing herbicidal composition and application of the
benzobicyclon-containing herbicidal composition. The
benzobicyclon-containing herbicidal composition isprepared from the benzobicyclon as a first
active component, diflufenican as a second
active component and an additive, wherein the weight ratio of the first
active component to the second active component is (1 to 90)-(90 to 1), preferably (1 to 50)-(50 to 1), more preferably (1 to 25)-(25 to 1), and most preferably (1 to 10)-(10 to 1). The composition can be prepared into agriculturally allowable
wettable powder,
water dispersible granules, suspension concentrates, dispersible oil-based suspensions, granules, fine granules,
macro granules,
effervescent granules, effervescent tablets and spreading oil. The benzobicyclon-containing herbicidal composition provided by the invention has excellent prevention and
control effect to northeastern
transplanting rice, direct seeded rice, dry directed-seed rice,
machine-transplanted seedlings, barnyard grasses in artificial rice
transplanting field, rice barnyard grasses, moleplant seeds,
paspalum paspaloides, crab grasses, Leersia oryzoides,
sagittaria trifolia, sagittaria pygmaea,
monochoria vaginalis, rhizoma alismatis and
scirpus juncoides, particularly has obvious synergic effect to the barnyard grasses, the rice barnyard grasses, the moleplant seeds,
sagittaria trifolia and the
scirpus juncoides, can lower the use cost, delays the resistance and is high in safety to crops.
