  • Patent number: 5846908
    Abstract: Methods and compositions for enhancing plant growth provide for foliar application of a substance which enhances the accumulation of formylterahydropteroyl polyglutamate (C.sub.1 -THF) in a treated plant. Treatment with substance that contribute to the structure of (C.sub.1 -THF) increase the rate and quantity of carbon fixation by the plant. Thereafter, plant growth is further improved either by exposure of the plant to elevated oxygen, illumination and heat or by foliar input of single carbon fragment sources. Opitmal results are obtained by combined treatment with a substance that can serve as a sink for C.sub.1 fragments produced in the leaf.

    Abstract: Described are new strains of Drechslera spp., which possess herbicidal effects against all varieties of barnyard grass, i.e., Echinochloa spp. as weed but do not give any influence to crops under cultivation such as rice. Weed control agents according to the present invention, which contain one or more of the novel strains, have high safety and selectivity, thereby providing practical control effects against barnyard grass. Weed control compositions according to the present invention, which contain one or more of the new strains in combination with one or more chemical herbicides, have sufficient herbicidal effects even at dosages which are too low to permit control of weeds when they are applied singly, thereby making it possible to reduce the dosage of herbicides. The weed control compositions can therefore contribute to the prevention of environmental pollution and the occurrence of weeds with acquired pesticide resistance.

  • Patent number: 5219825
    Abstract: The invention relates to synergistic herbicidally active compositions. The quantity required for a given herbicidal effect is substantially lower than that required for the herbicide itself. The compositions of the invention comprise in combination a herbicide which brings about active oxygen species formation in plants and a substance which binds copper or zinc, or a substance which reacts with a thiol moiety of a thiol containing enzyme. The herbicide and metal binding or thiol binding component can be applied together or separately.
