Antiseptic
Kresoxim-methyl is a high-efficiency, broad-spectrum and novel kind of fungicide. It has excellent treatment efficacy on strawberry powdery mildew, melon powdery mildew, cucumber powdery mildew, pear scab and other diseases. It is capable of controlling the treatment of Ascomycetes, Basidiomycetes, Deuteromycetes, Oomycetes and most kinds of other diseases. It has inhibitory effect on spore germination and growth of mycelium inside the leaf with activities of protection, treatment and eradication. It has good permeability and local systemic activity with long duration period. It has been widely applied for controlling crop diseases on fruit trees, vegetables, tea, tobacco, etc. In addition, the product can have a positive physiological regulatory function on the crop which is capable of inhibiting the generation of ethylene, helping crops have a longer period of time to ensure the energy storage and guarantee the biological maturity; it can significantly improve the crop nitrification reductase activity, when the crop is subject to attack from viruses, it can accelerate the formation rate of resistant virus proteins.

Precautions
1: Kresoxim-methyl should not be used in combination with strong alkali, strong acidic substances such as pesticides.
2: The safety interval of product is four days with crop being subject to spraying at most at 3-4 times per quarter.
3: People, upon application of this product, should wear masks, gloves and goggles, and should not make things and drinking during spraying and should promptly wash hands and face after spraying.
4: pregnant women and lactating women should not touch.
5: it has certain toxicity on aquatic fishes and should be kept from contaminating surface water.
6: it has excellent efficacy in controlling powdery mildew. Owning to that the powdery mildew fungus is prone to develop drug resistance. Application of Kresoxim-methyl in area had been subject to long-term application of triazole fungicides will achieve more pronounced efficacy and it can be mixed with thiophanate-methyl for application.
7: It should be stored in dry, cool, ventilated, rainproof place and should be away from fire and heat source. It should be put in place out of the reach of children and locked. Avoid storing it together with food, drink and feed.
Uses
It is a kind of Strobilurin fungicide and is mainly applied to cereals, rice, potatoes, apples, pears, pumpkins and grapes. It also has protection, treatment and eradication activity on the Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes and other pathogenic fungi with long duration period. Under recommended dose, it is safe to crops without injury-free and safe for the environment.
