4 results about "Saflufenacil" patented technology

The present application relates to the field of pesticide chemical industry technology, and discloses a post-treatment method for a saflufenacil-containing reaction solution. The post-treatment method includes the following steps: (1) after phase separation of a saflufenacil-containing reaction solution, performing desolvation treatment on an organic phase, and then adding a first organic solvent for stirring; (2) after the stirring is completed, performing filtration, leaching an obtained filter cake with a second organic solvent, and obtaining saflufenacil after drying. The post-treatment method provided by the present application can simply and efficiently treat the saflufenacil-containing reaction solution, with a product yield of over 90% and a content of about 98%.

The present invention relates to a combination or a composition comprising saflufenacil and epyrifenacil as well as to a method for weed control, which method comprises applying an effective amount of said herbicidal combination or composition to a non-crop area or to the cultivation area of a crop, where weeds grow or may grow. The invention also relates the use of the combination or of the composition comprising saflufenacil and epyrifenacil for weed control in a non-crop area or in the cultivation area of a crop.

The application discloses a pesticide composition containing annonaceous acetogenins and triflumuron and application thereof, and belongs to the technical field of pesticides. Effective components of the composition are the mass ratio of 1:10 to 20:1 of the annonaceous acetogenins and the triflumuron, wherein the annonaceous acetogenins are ortho-bis-tetrahydrofuran lactones extracted from seeds of Annona squamosa, and the purity is greater than or equal to 90%. The total mass percentage content of the effective components in the composition is 10% to 30%, and the rest is a pesticide adjuvant. The composition can be prepared into various dosage forms such as suspending agents, emulsifiable concentrates, suspending seed-coating agents, soluble granules or micro-capsule suspending-suspending agents. The two effective components with different action mechanisms are scientifically compounded, and the composition shows a significant synergistic effect on piercing-sucking mouthpart pests such as wheat aphids, corn aphids and brown planthoppers, and the highest co-toxicity coefficient (CTC) can reach 176.31. The composition can effectively reduce the field chemical pesticide dosage, delay the development of pest resistance and reduce pesticide residues, and has the characteristics of high efficiency, low residue and environmental friendliness.

The application discloses an insecticidal composition containing flubendiamide and triflumuron, wherein flubendiamide and triflumuron are used as active ingredients, and the mass ratio of flubendiamide to triflumuron is 1:50-50:1. The insecticidal composition can be used for controlling Lepidoptera, Homoptera, Hemiptera, Thysanoptera and Coleoptera pests, has obvious synergistic effect, reduces the amount and frequency of pesticide application, reduces the control cost, overcomes the defects of easy resistance caused by long-term single use, and prolongs the service life of the pesticide.
