Abstract: An engineered radioactive polymeric microsphere, and a preparation and application thereof. The preparation method includes: adding a styrene monomer and a disperser and/or a crosslinker into a medium, followed by feeding of nitrogen or helium and stirring to obtain a first reaction mixture; heating the first reaction mixture, and adding an initiator, followed by reaction under stirring at a constant temperature to obtain a second reaction mixture; subjecting the second reaction mixture to washing with ethanol and water, and vacuum drying to obtain a crude polymeric microsphere; subjecting the crude polymeric microsphere to radiation-induced graft polymerization with a functional monomer to obtain the functionalized polymeric microsphere; and exposing the functionalized polymeric microsphere to a radionuclide to prepare the engineered radioactive polymeric microsphere.

Abstract: An isoxazoline compound with optical activity is shown in the formula (I). The compound of the formula (I) has excellent herbicidal activity, can be used for weeding pre- and post-emergence, and can also be used for soil treatment. The compound of the formula (I) can effectively control various broad-leaved weeds, grass weeds and Cyperaceae weeds, and can control various resistant weeds, such as glyphosate-resistant weeds. The excellent weeding effect can be obtained at a low dose. The compound has good safety to crops such as corn, wheat, rice, soybean and sugar beet. The compound can be used as a selective herbicide in crop fields in agriculture, and can also be used as a non-selective herbicide in non-cultivated land, fallow land, woodland, orchards and ridges.

Abstract: The present invention relates to a herbicidal composition and an application method thereof. The composition comprises two active components of A and B, wherein the component A is selected from a compound shown in the following general formula: The component B is selected from one of ACCase inhibitor herbicides. The herbicidal composition of the present invention is especially suitable for controlling weeds which are tolerant or resistance to organophosphorus herbicides, especially glyphosate.
