Picoxystrobin is a major strobilurin fungicide, which has been widely used to control plant diseases.

- Biochemistry:

Picoxystrobin can inhibit mitochondrial respiration by preventing electron transfer in the Qo center of cytochrome b and c1.

- Mode of Action:

Preventative and curative fungicide with unique distribution properties including systemic (acropetal) and translaminar movement, diffusion in leaf waxes and molecular redistribution in air.

After the agent enters the bacteria cells, it blocks the electron transfer between cytochrome b and cytochrome c1, thereby inhibiting the respiration of mitochondria and destroying the energy synthesis of the bacteria And loop. Then, due to lack of energy supply, germ spore germination, hyphae growth and spore formation are all inhibited.

- Uses:

For broad spectrum disease control, including Mycosphaerella graminicola, Phaeosphaeria nodorum, Puccinia recondita (brown rust), Helminthosporium tritici-repentis (tan spot) and Blumeria graminis f.sp. tritici (strobilurin-sensitive powdery mildew) in wheat; Helminthosporium teres (net blotch), Rhynchosporium secalis, Puccinia hordei (brown rust), Erysiphe graminis f.sp. hordei (strobilurin-sensitive powdery mildew) in barley; Puccinia coronata and Helminthosporium avenae, in oats; and Puccinia recondita, Rhynchosporium secalis in rye. Application typically 250 g/ha.

Picoxystrobin is mainly used for the treatment of grain and fruit diseases, such as the prevention and treatment of wheat leaf blight, leaf rust, ying blight, brown spot, powdery mildew, etc. Its use amount is 250g/hm2; and it is in use In the prevention and control of barley and apple diseases, it has special effects on diseases that are not highly effective using azoxystrobin and other agents. After the grains are treated with Picoxystrobin, high-yield, good-quality, large and plump grains can be obtained.

- Toxicity:

 Low Toxicity
