A livestock food product that includes at least one or more plant-based agricultural feeds containing at least one or more plant residues of at least one or more noxious and / or invasive plants. The one or more residues containing no more than 10% of the naturally occurring amount, by weight, of at least one noxious compound that was present in the one or more noxious and / or invasive plants, the naturally occurring amount being the amount of the at least one noxious compound that was present in the noxious and / or original plants while they were alive. The one or more noxious and / or invasive plants including at least one of hemp, tumbleweed, sagebrush, or cheat grass. These plants fibers contain valuable nutrients and flourish under semiarid conditions in abundance. Proper harvesting techniques, bioprocessing can make these plant valuable resources available to mankind environmentally and economically.

The invention relates to a pre-emergence weeding composition and application thereof, and belongs to the technical field of pesticide compositions. The weeding composition takes pyroxasulfone and bisamide as effective components, and the mass ratio of pyroxasulfone to bisamide is (1-20): (20-1). The weeding composition can be prepared into a pesticide preparation, and the pesticide preparation comprises wettable powder, a suspending agent, a dispersible oil suspending agent, a microemulsion, an emulsion in water, granules and water dispersible granules. The pre-emergence weeding composition provided by the invention can effectively prevent and eliminate annual gramineous weeds and annual broadleaf weeds, can be safely used in wheat fields, soybean fields, peanut fields and vegetable fields, and is safe to crops and also safe to the environment. The weeding composition can be widely used for preventing and killing weeds such as lolium multiflorum, alopecurus aequalis, wild oats, bromegrass, chenopodium album, amaranthus retroflexus and shepherd's purse, and still has a relatively good prevention effect on intractable weeds.

The application discloses a PCR detection primer, a detection kit and a detection method for a PS II inhibitor herbicide-resistant Chenopodium. psbA The application finds a mutation site of PS II inhibitor resistance by screening and comparing the DNA sequences of the Chenopodium with different resistance to the PS II inhibitor herbicide, and designs a specific PCR detection primer pair according to the mutation site, and determines the Chenopodium with the resistance to the PS II inhibitor herbicide The application establishes a PCR kit and a PCR identification method for the Chenopodium with the resistance to the PS II inhibitor herbicide. The PCR kit or the PCR identification method can be used for rapidly and accurately detecting the Chenopodium with the resistance to the PS II inhibitor herbicide, and has the advantages of simple operation, high speed, low cost, high accuracy and the like.

The application discloses application of inorganic salt in promoting seed germination of wild oat and a method for removing wild oat weeds, and belongs to the technical field of agricultural weed control, wherein the inorganic salt is a KH2PO4 aqueous solution or a water solution compounded by Na2SeO4 and CaCl2; the concentration of the KH2PO4 aqueous solution is less than 1 g / L; in the water solution compounded by Na2SeO4 and CaCl2, the concentration of Na2SeO4 is 5 mg / L, and the concentration of CaCl2 is 50 mM. The wild oat seed germination promoter can improve the germination rate of wild oat seeds, lays a foundation for subsequent concentrated treatment of germinated wild oat weeds, and effectively reduces the inventory of wild oat seeds in the soil by making the wild oat seeds in the soil germinate massively and uniformly in a short time and then adopting conventional weeding measures, so that the purpose of long-term control of wild oat weed damage is achieved.
