The application belongs to the technical field of pesticide weeding, and discloses a weeding composition containing icafolin and application thereof. The weeding composition contains active ingredient A and active ingredient B. The active ingredient A is icafolin, the active ingredient B is any one of benzenesulfonamides or thiophenesulfonamides, and the mass ratio of the active ingredient A to the active ingredient B is 1:2-200:4.5. The weeding composition provided by the application has high weeding activity, and the mixture of the two has superimposition effect, complementary mechanism, and an expanded weed spectrum. The weeding composition has good weed control effect in corn fields, wheat fields, peanut fields and soybean fields.

The present application relates to the technical field of pesticides, and discloses a herbicidal composition of a mixture of tribenuron, sodium 2-methyl-4-chloro and tebuconazole, wherein the mass ratio of the composition of active ingredient A (tribenuron and sodium 2-methyl-4-chloro) to active ingredient B (tebuconazole) is 0.5-30:1.The herbicidal composition has obvious synergistic effect on agricultural weeds, is good in quick-acting property, and is low in toxicity to human beings and livestock; in addition, the mechanism of action of tribenuron, sodium 2-methyl-4-chloro and tebuconazole is different, and the herbicidal composition can delay the drug resistance of weeds, and is an ideal herbicide.

This invention provides a gene for Brassica napus resistant to the sulfonylurea herbicide bensulfuron-methyl, encoding the amino acid sequence shown in SEQ ID NO:2, exhibiting resistance to the sulfonylurea herbicide bensulfuron-methyl. Preferably, the nucleotide sequence of the Brassica napus resistant gene to bensulfuron-methyl is shown in SEQ ID NO:1. The invention also provides the application of the above-mentioned Brassica napus resistant gene to bensulfuron-methyl in detecting plants, plant cells, or plant tissues resistant to the sulfonylurea herbicide bensulfuron-methyl, and in cultivating plants, plant cells, or plant tissues resistant to the sulfonylurea herbicide bensulfuron-methyl. The Brassica napus resistant gene to bensulfuron-methyl of this invention provides stable resistance to the sulfonylurea herbicide bensulfuron-methyl. Brassica napus with this gene recovers quickly from herbicide damage, exhibits excellent plant type, normal fruit setting, and can be safely used at the recommended field concentration.
