  • Combination of crop protection agents with hydrogen bond-forming polymers
    Publication number: 20020042345
    Abstract: The present invention describes the combination of an agrochemically active compound with a polymer with formation of hydrogen bonds for the controlled release of this active compound. Both the polymer and active compound have functional groups which permit the formation of hydrogen bonds.

  • Combinations of crop protection agents with cationic polymers
    Publication number: 20020019314
    Abstract: The present invention relates to the combination of a combination of an anionic agrochemically active compound with a cationic polymer with formation of electrostatic interaction for the controlled release of this active compound. This polymer preferably contains cationic quaternary nitrogen atoms. The combinations according to the invention or agrochemical formulations containing these combinations permit the suppression of antagonistic interactions between different active compounds and an increase in the crop selectivity of individual active compounds.

  • Synergistic active compound combinations for controlling harmful plants in crops of useful plants
    Patent number: 6316387
    Abstract: The present invention relates to the use of a herbicidal combination for the selective control of harmful grasses from the group consisting of Phalaris supp. and Lolium supp. in crops of useful plants, each combination comprising: A) one or more compounds from the group of the 1,2,4-triaznones; and B) one or more compounds from the group consisting of (het)aryloxyphenoxy-propionic acid derivatives and cyclohexanedione oximes, and to the novel herbicidal compositions defined in the description suitable for the use according to the invention. The compositions are also suitable for reducing the application rate and the phytotoxicity of the individual herbicides in the crops.

  • Synergistic herbicidal agents
    Patent number: 6159900
    Abstract: When herbicides are applied, surfactants can affect the wettability of leaves of the plants and the effectiveness of the herbicides. According to the invention, a particular intensification of action is achieved when surfactants from the group comprising the C.sub.10 -C.sub.18 -alkyl polyglycol ether sulfates and their physiologically acceptable salts together with leaf-acting selective herbicides or the leaf-acting non-selective herbicides glyphosate, paraquat or diquat are applied.

  • Synergistic herbicidal compostitions
    Patent number: 5872077
    Abstract: The invention relates to herbicidal compositions which compriseA) a compound of the formula I or salts thereof ##STR1## in combination with B) one or more compounds selected from the group comprising growth-regulator-type herbicides, dicamba and its salts, diflufenican, nitrodiphenyl ethers, sulfonylureas which differ from that of the formula (I) and their salts, and selective grass herbicides.They are particularly suitable for selectively controlling weeds in rice, soya and other crops.
