The invention relates to the technical field of pesticides, and discloses a weeding composition and application thereof. The active ingredients of the composition comprise dithiopyr and pretilachlor, the dithiopyr and the pretilachlor can play a good effect in a wide range of 6: 1 to 1: 10 in mass ratio, and particularly, the composition shows a remarkable synergistic interaction effect on weeds in a rice field in a ratio range of 4: 1 to 1: 7. In addition, a safener fenclorim can also be added into the composition, so that the safety to rice crops is remarkably improved. The composition disclosed by the invention can be used for transplanting rice and direct seeding rice, is applied in multiple periods such as pre-emergence or post-emergence, can be used for effectively preventing and removing weeds such as barnyard grass, leptochloa chinensis, digitaria sanguinalis, polygonum sylvestre, cyperus difformis, rhizoma alismatis and eleocharis yokoscensis, and has the advantages of synergism, safety, long lasting period and obvious yield increase.

The invention discloses pyrithiobac-methyl ionic liquid and a preparation method and application thereof.The pyrithiobac-methyl ionic liquid is obtained by taking pyrithiobac-methyl as anions and combining the pyrithiobac-methyl with structure-modified quaternary ammonium cations, and after pyrithiobac-methyl is combined with cations with different carbon chain lengths, the pyrithiobac-methyl ionic liquid has high surface activity and thermal stability and can be used for preparing the pyrithiobac-methyl ionic liquid. Compared with a conventional pyrithiobac-methyl agent, the weeding efficiency and biological selectivity of the agent can be remarkably improved, the same weeding effect can be achieved in a targeted mode with a lower dosage, and therefore the purpose of environmental protection is achieved; the pyrithiobac-methyl ionic liquid microsphere is applied to preparation of the pyrithiobac-methyl ionic liquid microsphere, and a good pesticide effect can be achieved for a long time at a low pesticide concentration, so that a better weeding effect is achieved on the premise that side effects on the environment are reduced, and the pyrithiobac-methyl ionic liquid microsphere is greener and more environmentally friendly and has a great application prospect.

The application provides a herbicidal composition containing benziproxon and application, wherein the active component of the herbicidal composition comprises active component A and active component B; the active component A is benziproxon; the active component B is selected from one of pyrithiobac-acid and dithiopyr; and the weight ratio of the active component A and the active component B is 100:1-1:100. The herbicidal composition containing benziproxon has a synergistic effect in weed control, improves the weed control effect of the pesticide, reduces the amount of the pesticide, lowers the cost, and can delay the emergence of weed resistance.

The present invention relates to the technical field of herbicides, and provides a herbicide composition and a use thereof. The herbicide composition is composed of dithiopyr and oxadiargyl, wherein the mass ratio of the dithiopyr to the oxadiargyl is (0.3-6.7):1. Binary compounding of the dithiopyr and the oxadiargyl can extend the weed-controlling spectrum and enhance control efficacy against resistant weeds. Additionally, due to the long lasting period of the oxadiargyl, the lasting period of the herbicide composition is prolonged; and compounding of the dithiopyr and the oxadiargyl according to the mass ratio of (0.3-6.7):1 reduces the amount of usage of the oxadiargyl and improves the safety of the herbicide composition. The present invention solves the technical problems in the prior art of a short lasting period, a high safety risk, and low control efficacy against resistant weeds of a herbicide applied to rice.

The invention relates to the technical field of pesticides, and discloses a paddy field weed control method, which comprises the step of applying a weeding composition of dithiopyr and disulfuron to a paddy field. The weeding composition provided by the invention is used for preventing and removing weeds such as paddy field barnyard grass, leptochloa chinensis, digitaria sanguinalis, green bristlegrass, eleusine indica, monochoria vaginalis, lindernia procumbens, ammannia baccifera, polygonum lilac, arrowhead, cyperus difformis, cyperus iria, fimbristylis miliacea, scirpus planiculmis, eleocharis yokoscensis, scirpus juncoides and the like, and has a surprising and unexpected synergistic effect; the weeding activity is more remarkable than the expected sum of the activity of a single herbicide, the synergistic effect is more remarkable under the condition of low dosage, the dosage can be reduced, the pollution to the environment is reduced, the use cost is reduced by reasonable compounding, the adaptability of the product to high temperature is improved, the lasting period of the product to high temperature is prolonged, and the weeding composition has a better application prospect.

The invention belongs to the field of pesticides, and particularly relates to a dithiopyr-containing weeding composition as well as a preparation method and an application method thereof. The weeding composition comprises dithiopyr, an organic acid ester, a ketone solvent and a nonionic emulsifier. The weeding composition is low in volatilization rate and free of low-temperature precipitation, and the dispersion stability and the pesticide effect of the weeding composition are effectively improved. In addition, the preparation method of the composition provided by the invention is simple and efficient, convenient to operate and easy to realize large-scale production.

The invention provides a herbicide composition and application thereof, and relates to the technical field of herbicides, and the herbicide composition comprises dithiopyr and oxadiargyl. The dithiopyr and the oxadiargyl are subjected to binary compounding, so that the weed control spectrum can be expanded, and the control effect on resistant weeds is improved; meanwhile, the oxadiargyl has the characteristic of long lasting period, so that the lasting period of the compounded herbicide composition is prolonged; the use amount of oxadiargyl is reduced, and the safety of the herbicide composition is improved. The technical problems that in the prior art, a herbicide applied to rice is short in lasting period, high in safety risk and low in control effect on resistant weeds are solved.
