    摘要: The present invention relates to the technical field of plant protection formulations. In particular, the invention relates to non-aqueous single liquid-phase dispersions comprising herbicidal active substances which are known as hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, especially triketones, and more particular tembotrione, in combination with an adjuvant, citric acid (in the following, if not stated otherwise, citric acid refers to anhydrous citric acid), and at least one synthetic amorphous silica-based rheology modifier, wherein said modifier is most preferred a mixture of a hydrophilic and a hydrophobic synthetic amorphous silica-based rheology modifier, which are useful for the selective control of weeds and weed grasses in important plant crops The dispersions are suitable for use in the field of plant protection.

    摘要: The invention concerns combinations of one or more HPPD inhibitors selected from a group comprising an isoxazole, a triketone, and a callistemone; a cereal crop safener selected from a group comprising mefenpyr-diethyl, cloquintocet and cloquintocet-mexyl; and one or more of the herbicides, selected from the groups comprising: i) a PSII inhibitor, including bromoxynil, ioxynil, and chlorotoluron, ii) a synthetic auxin, including halauxifen-methyl, fluroxypyr and MCPA, iii) a PPO inhibitor, including bifenox, iv) a PDS inhibitor, including flurochloridone, diflufenican and picolinafen. The invention also relates to a method for controlling unwanted vegetation applying such a combination to a cereal crop.
