Picoxystrobin - Reference Information
| LogP | 3.68 at 20℃ |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| background | pyridoxine is currently the best methoxyacrylate fungicide. it was successfully developed by Syngenta. in 2006, Syngenta sold the global sales right of pyridoxine to DuPont in the United States. it has been sold in China and the relevant patent protection expired on January 13, 2008. This product is mainly used to prevent and control wheat foliar diseases such as leaf blight, leaf rust, glume blight, brown spot, powdery mildew, etc., compared with other existing methoxyacrylate fungicides, It has a stronger therapeutic effect on wheat leaf disease, net spot disease and moire disease. |
| application | pyridine is mainly used to treat grain and fruit diseases, such as wheat leaf blight, leaf rust, blight, brown spot, powdery mildew, etc. Its usage amount is 250g/hm2. Moreover, when used for disease control of barley and apple, it has special effect on diseases with low efficacy of azoxystrobin and other chemicals. After the grain is treated with pyridoxyl ester, grains with high yield, good quality, large and full grains can be obtained. |
| drug action | pyridoxyl is a systemic broad-spectrum fungicide, which has the effects of eradication, protection, penetration and internal absorption. The agent enters the germ cell and combines with the Q0 site of cytochrome B on the mitochondria to block the electron transfer between cytochrome B and cytochrome c1, thereby inhibiting the respiration of mitochondria, destroy the energy synthesis of germs. Due to lack of energy supply, germ spore germination, hyphal growth and spore formation are inhibited. It is effective to control strains resistant to 14-demethylase inhibitors, benzamide, dicarboxamide and benzimidazole. Once absorbed by the leaf, Blixide will move in the xylem and flow in the transportation system with the water flow; it also flows in the gas phase of the leaf surface and flows in the xylem after being absorbed into the leaf from the gas phase. The crops treated with pyridoxine [250g(a. I.)/hm2] spray under no rain conditions were compared with the crops exposed to lOmm for up to 1 hour after the same spray treatment for 2h. The results showed that the control effect of the two on barley leaf blight was the same. |
| biological activity | Picoxystrobin is a major strobilurin fungicide and has been widely used to control plant diseases. Picoxystrobin can inhibit mitochondrial respiration by blocking electron transfer from the Qo centers of cytochrome B and c1. |
