This invention discloses a P450 gene of crabgrass from paddy fields and its application in conferring resistance to cyhalofop-butyl in plants. The expression level of this gene in the resistant crabgrass biotype is significantly higher than that in the sensitive biotype. By constructing it into a plant expression vector and transforming it into maize, the resulting transgenic maize plants were sprayed with 11.25 g ai ha at the 3-4 leaf stage. ‑1 After treatment with cyhalofop-butyl, the maize exhibited significantly higher herbicide resistance and survival rate than wild-type maize. This invention confirms that the crabgrass P450 gene is directly related to herbicide resistance, providing a foundation for using this gene to breed transgenic crops resistant to ACCase inhibitor herbicides, and has broad application prospects in the field of agricultural biotechnology.

This invention discloses a strain of *Boletus urinaria* PP013 and its applications, with the preservation number CGMCC No. 40661. This invention also provides a sustainable, cyclical understory cultivation method, including liquid spawn culture, spawn culture, soil covering for fruiting, and understory inoculation. This method selects shallow-rooted tree species such as *Delonix regia* and *Gardenia jasminoides*, and lays a layer of dry weeds consisting of sugarcane bagasse, miscanthus, and *Digitaria sanguinalis* under the trees. Artificially cultivated fruiting bodies about to open their gills are placed under the trees as a live spore source for spore production. After spore production, the understory is covered with dry weeds and watered. The following year, after fruiting, some fruiting bodies are retained for natural spore production, achieving a single inoculation and multi-year cyclical fruiting. This invention creatively utilizes fruiting body spores for natural inoculation, replacing the traditional direct mycelial inoculation method. It boasts a high success rate of establishment, low long-term production costs, and represents a highly efficient forest-fungus integrated management model.

The invention provides a weeding composition containing flazasulfuron and sulfometuron methyl as well as a suspending agent dosage form and application of the weeding composition. After flazasulfuron and sulfometuron methyl are compounded, the lasting period can be prolonged to several months and even more than one year; the weeding spectrum is expanded, the control effect on weeds such as digitaria sanguinalis, acalypha australis, eleusine indica and moleplant seeds is improved, and the control varieties of perennial weeds are increased; compared with a single agent, the compounding can reduce the use amount of effective components and improve the safety to lawns.

The invention discloses a folium artemisiae argyi endophytic diplodia mediterranean strain AY7B and application thereof in weed control, and belongs to the field of microorganisms. The strain is separated from healthy and disease-free folium artemisiae argyi, is preserved in the China General Microbiological Culture Collection Center (CGMCC) on November 11, 2024, has the preservation number of CGMCC NO.41594, and is classified and named as bicognia mediterranean. The strain is named as bicognia mediterranean, and the strain is named as bicognia mediterranean. Two herbicidal active substances, namely fermentation liquor and solid fermentation extract, prepared by taking the strain as a core have inhibition effects on seed germination and seedling growth of common weeds such as digitaria sanguinalis and amaranthus viridis, and the inhibition rates on roots and buds of amaranthus viridis respectively reach 91.0% and 94.6%. The application provides a landing scheme for the development of a novel microbial herbicide, and has both environmental safety and industrialization potential.

The invention discloses a cyhalofop-butyl-resistant digitaria calorata MYB transcription factor gene and application thereof, and relates to the field of plant genetic engineering, and the expression of the gene in a resistant digitaria calorata biological type is remarkably up-regulated. After a plant expression vector is constructed and corn is transformed, after 11.25 g a.i. Ha-1 cyhalofop-butyl is sprayed on a transgenic corn plant in a 2-leaf stage, the pesticide resistance and the survival rate are obviously enhanced, and the transgenic corn plant is obviously superior to a wild type. The invention proves that the MYB gene can endow plants with resistance to acetyl-coenzyme A carboxylase (ACCase) inhibitor herbicides such as cyhalofop-butyl and the like, provides a new gene resource for cultivating transgenic crops resisting the acetyl-coenzyme A carboxylase (ACCase) inhibitor herbicides, and has important application value.

The invention discloses an N-phenyl phthalimide compound containing a nicotinic acid fragment and an ester group structure as well as a preparation method and application of the N-phenyl phthalimide compound, and belongs to the field of herbicides. The technical problem that existing herbicides cannot give consideration to both herbicidal activity and use safety is solved. The structural general formula of the compound is shown as a formula (I) or a formula (II), wherein the formula (I) and the formula (II) are shown in the specification. The N-phenyl phthalimide compound containing the nicotinic acid fragment and the ester group structure provided by the invention has good inhibitory activity on PPO. The herbicidal composition has especially excellent herbicidal activity on morning glory, digitaria sanguinalis, amaranthus retroflexus, abutilon fiber and other weeds, especially has an excellent effect on dicotyledonous weeds, and the control effect is even superior to that of some commercially available commercial herbicides. The compound can be used as a PPO inhibitor. The weeding composition can also be prepared into a weeding agent for preventing and controlling crop weeds.
