The invention belongs to the field of weeding, and relates to a mixing weed killer containing bentazone, rimsulfuron and mesotrione, and an application thereof. The mixing weed killer adopts the bentazone, the rimsulfuron and the mesotrione as main effective components, wherein a mass ratio of the bentazone to the rimsulfuron to the mesotrione is 0.1-80:0.1-80:0.1-80, the total mass percentage ofthe three materials in the mixing weed killer is 1-85%. The mixing weed killer provided by the present invention can be applicable for weeding in the corn field after seedling, specifically provides significant effects for prevention and elimination of various grassy weeds or broadleaf weeds in the corn field. Compared to the single weed killer, in the premise of improvement of the efficacy, the weeding composition provided by the present invention delays the resistance generating of the weeds, and has wide weeding spectrum and long effective duration, and provides safeties for the corn and the succeeding crops.

The invention discloses a weeding composition containing bentazone and propanil and application thereof. The weeding composition comprises the following main effective components: the bentazone and the propanil, wherein the mass ratio of the bentazone to the propanil is (0.1-80):(0.1-80). The weeding composition disclosed by the invention can be applied to the post-emergence weeding for paddy fields and especially has an outstanding effect on preventing and weeding gramineous weeds and broadleaf weeds in the paddy fields; in addition, compared with a single agent, the weeding composition disclosed by the invention has the advantages of weed resistance delay performance, broad weeding spectrum, and long acting period under the precondition of enhancing a weeding effect and has safety for paddy rice and succession crops.

The invention belongs to the field of pesticides, and relates to a mixed herbicide composition containing bispyribac-sodium and pretilachlor. The herbicide composition adopts the bispyribac-sodium and the pretilachlor as main active components, the weight ratio of the bispyribac-sodium and the pretilachlor is 1 to 99:1 to 99, and the herbicide composition is mainly applied to postemergence weeding in paddy fields. Compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the pesticide effect is enhanced, has a broad weeding spectrum and long persistence, and is safe for rice and next-stubble crops.

The invention relates to a weeding composition which is composed of isoxaflutole, halosulfuron-methyl and fluroxypyr in the mass ratio of (0.1-40): (0.1-20) (0.1-20). The weeding composition containing isoxaflutole, halosulfuron-methyl and fluroxypyr, namely a composite herbicide, has a remarkable effect in application to post-emergence weeding in sugarcane fields, particularly in application to preventing and weeding various gramineous weeds and broadleaf weeds in the sugarcane fields.
