The invention provides a water dispersible granule containing a pyroxasulfone and flumioxazin weeding composition. The water dispersible granule comprises pyroxasulfone, flumioxazin, a dispersing agent, a wetting agent, a disintegrating agent, an adhesive and filler. According to the invention, by selecting the proper dispersing agent and wetting agent as well as the combination and compatibility of the dispersing agent and wetting agent, performing targeted screening on the dosage of the dispersing agent and wetting agent, and supplementing other auxiliaries, the water dispersible granules with excellent preparation performance indexes such as high activity component content, suspension rate, disintegration property and the like can be obtained, and rapid disintegration (less than or equal to 60 seconds) and high suspension rate (more than or equal to 90 percent) are realized. The invention also relates to a preparation method and application of the water dispersible granule.

The invention relates to the technical field of pesticides, and discloses a weeding composition and application thereof. The effective components of the weeding composition comprise the flufenacet, the flumioxazin and the diflufenican. The weeding composition can be used for preventing and treating weeds in wheat fields. The weeding composition provided by the invention is used for preventing and killing weeds such as alopecurus macrostachyus and lolium multiflorum in a wheat field, has a surprising and unexpected synergistic effect, and has more remarkable weeding activity than the expected sum of the activity of a single herbicide and the activity of a single herbicide or the activity of a combination of any two herbicides, so that the weeding composition is a novel weeding composition for preventing and killing weeds such as alopecurus macrostachyus and lolium multiflorum. 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 agricultural cost is reduced through reasonable compounding, and the bactericidal composition has a better application prospect.

The invention discloses a preparation method of biochar improved by an acidic deep-eutectic solvent and application of the biochar in degradation of fomesafen, and relates to the technical field of water pollution treatment and environmental functional materials. The preparation method comprises the following steps: mixing biomass powder and an acidic deep-eutectic solvent, and carrying out heating reflux reaction to obtain biochar; the acidic eutectic solvent takes choline chloride as a hydrogen bond acceptor and methanesulfonic acid as a hydrogen bond donor. By introducing the acidic eutectic solvent, the conditions of the traditional hydrothermal carbonization method are optimized, and hydrothermal carbonization of biomass can be carried out at normal pressure and 200 DEG C or below. In addition, efficient degradation of fomesafen pesticide residues in a water body is realized by utilizing the biochar activated persulfate optimally prepared by the method, and the biochar activated persulfate shows good degradation performance in a neutral to alkalescent water environment and can be used for purification treatment of pesticide polluted water bodies.

The present invention belongs to the field of pesticides, and specifically relates to a herbicidal composition and the use thereof. The composition comprises a herbicidally effective amount of an active ingredient A and an active ingredient B, wherein the active ingredient A is; and the active ingredient B is selected from one or more of the following compounds or acids / esters / salts thereof: diflufenican, picolinafen, fluridone, fenpyrazone, saflufenacil, flumioxazin, sulfentrazone or. The composition can effectively control problems of gramineous weeds, cyperaceous weeds, broadleaf weeds, etc., and exhibits characteristics of an expanded herbicidal spectrum, a reduced application dosage, the ability to produce a synergistic effect, effectiveness in controlling resistant weeds, etc.

This invention provides a herbicidal composition containing benzoxam, wherein the active ingredients comprise active ingredient A and active ingredient B; the mass ratio of active ingredient A to active ingredient B is 1:10-10:1; active ingredient A is benzoxam, and active ingredient B is one or both of pyrimethanil and propyzoxystrobin. This herbicidal composition exhibits a significant synergistic effect, significantly improving the herbicidal efficacy of the herbicide, reducing the dosage required, slowing the development of pesticide resistance, and mitigating environmental pollution. This herbicidal composition can be used for weed control in non-cultivated land, demonstrating excellent herbicidal efficacy.

This invention provides a compound herbicide, its preparation method, and its application, relating to the field of pesticide technology. The compound herbicide provided by this invention combines metolachlor or butachlor, nicosulfuron, and propyzoxystrobin or propyzoxystrobin. Through extensive experiments, the inventors discovered that these herbicides, with their different mechanisms of action and weed-killing spectra, not only have a synergistic effect when combined, but also broaden the weed-killing spectrum. Furthermore, all three have short residual periods, do not affect subsequent crops, and facilitate crop rotation. Under different formulations, it can be used in sorghum fields, sunflower fields, corn fields, potato fields, rice fields, etc., adding new agents and options for weed control, reducing pesticide application rates, and promoting sustainable agricultural development.

The invention relates to the technical field of bactericides for crops, in particular to a microencapsulated bactericidal composition containing mefonamide and resistant bacillus cereus and a preparation method of the microencapsulated bactericidal composition. The sterilization composition is prepared from 1%-10% of mefonamide, 1%-10% of bacillus cereus with resistance to mefonamide, 5%-20% of microcapsule wall materials, 1%-5% of auxiliaries and the balance water. By microencapsulating the fomefonamide and compounding the microencapsulated fomefonamide with the resistant bacillus cereus, the compatibility problem of chemical agents and biocontrol bacteria is solved, and synergistic interaction of chemical control and biological control is realized. The composition can effectively prevent and treat various plant fungal diseases, has the advantages of being long in lasting period, environmentally friendly and the like, can be processed into various dosage forms, and meets different agricultural production requirements.
