Definitions

  • the present invention relates to an improved fungicidal composition which comprises pyraclostrobin.
  • the composition is particularly applicable for the prevention and control of phytopathogenic fungus and bacterium.
  • crops may be infected by various fungus or bacterium leading to different kinds of diseases, while they may also be infected by various pathogenic or saprotrophic fungus (for example, fythium, phytophthora, rhizoctonia solani, fusarium and botrytis cinerea etc.) and bacterium (Erwinia carotovora etc.) in soil, resulting in seed rot, root rot and seedling death.
  • pathogenic or saprotrophic fungus for example, fythium, phytophthora, rhizoctonia solani, fusarium and botrytis cinerea etc.
  • bacterium Erwinia carotovora etc.
  • a fungicide is a natural or synthetic compound, which is used to protect the plants from the infection of fungus.
  • the present agricultural methods rely heavily on the use of fungicides. In fact, certain crops cannot grow effectively without the use of fungicides. With the use of fungicides, farmers can increase the yield and the quality of crops, leading to an enhancement of the value of crops. In most situations, the added value of crops is at least three times of the expenditure of the use of fungicides.
  • a synergistic effect is present when the activity of two or more compounds is greater than the combined activity of the compounds applied individually.
  • the present invention aims to provide an agricultural method and a composition with good efficacy against harmful fungus and bacterium, which could reduce dosage rates and/or enhance activity spectra and/or solve the problem of the management of drug resistance.
  • Pyraclostrobin is a known fungicidally active compound, with its chemical name as methyl N- ⁇ 2-[1-(4-chlorophenyl)-1 H-pyrazol-3-yloxymethyl]phenyl ⁇ (N- methoxy)carbamate, and its structure as:
  • Pyraclostrobin is a mitochondrial respiration inhibitor, with the same mechanism as those of other synthetic strobin counterparts. It inhibits mitochondrial respiration by blocking electron transfer between cytochromes b and C1 , which in turn prevents mitochondrion not to generate and provide the energy required by the cells for normal metabolism (ATP), eventually resulting in the death of cells.
  • ATP normal metabolism
  • Pyraclostrobin possesses a higher ability in inhibition of spore germination of bacterium and mycelium growth in leaves. With potential curative activity, it has a longer validity period. The said compound is rather weak in transfer around leaf apex or leaf base on a leaf and fumigation, but its transfer activity within a plant body is relatively strong. Meanwhile, as a hormonal fungicide, it can help the crops to absorb more nitrogen which is useful for their growth. In summary, with a broad applicable scope, pyraclostrobin has a protective function, curative function and systemicity, and it is also resistant to rain wash.
  • Pyraclostrobin is mainly applicable for the prevention and control of diseases on wheat, paddy rice, peanuts, grapes, vegetables, bananas, lemons, coffees, fruit trees, walnuts, tea trees, tobaccos, ornamental plants, grasses and other field crops. It can effectively prevent and control several diseases such as leaf blight, rust, powdery mildew, downy mildew, phytophthora disease, anthracnose, black spot, leaf spot, scab, brown spot and rhizoctonia rot caused by ascomycetes, basidiomycetes, deuteromycetes and oomycetes.
  • pyraclostrobin Because of its broad-spectrum fungicidal activity for preventing and controlling diseases on cereal crops, pyraclostrobin demonstrates an outstanding efficacy on the prevention and control of diseases on leaves and grains of the cereal crops, as well as increases their yields significantly. Regarding crop safety, the said compound has low toxicity, and thus it is safe to non-target organisms, and furthermore, it is also safe to the users and environment. According to the results of most of the experiments, pyraclostrobin has no phytotoxicity on crops under the recommended dosages. However, there is phytotoxicity for a very few particular species of American grapes and plums in a certain stage of their growth stages.
  • Copper calcium sulphate with a commodity name as "duoning" (_£ ⁇ ), is a non-selective protective fungicide which comprises copper ions and with low toxicity. It is equivalent to the bordeaux powder from industrialized production, but does not produce any stain on the leaves after spraying. Copper calcium sulphate acts through binding the released copper ions with several biological groups in the pathogenic fungus or bacterium in order to form the substances such as copper complexes, which in turn causes protein denaturation that helps to hinder and inhibit metabolism, resulting in the death of bacterium. The unique copper calcium compound would release fungicidal copper ions slowly in water, simultaneously with the germination and infection of the bacterium. Bacteria killing and prevention of diseases would be carried out in time.
  • Copper calcium sulphate is different from the general bordeaux mixture. Copper calcium sulphate solution is mildly acidic and could be mixed with the non-alkaline formulations with no metal ions, and thus it is convenient to use. The particles of copper calcium sulphate are small with a villous structure, and they could be distributed evenly and adhered tightly on the leaf surface of the crop after spraying. They are very resistant to rain wash. Furthermore, copper calcium sulphate comprises 12% of calcium sulphate. Apart from the prevention and control of diseases, it also has a function of calcium supplementation.
