Picoxystrobin 二嗪磷

Introduction:

Picoxystrobin is a fungicide belonging to the strobilurin group of chemicals. It is a preventative and curative fungicide with systemic and translaminar movement, acting by inhibition of mitochondrial respiration by blocking electron transfer at the Qo centre of cytochrome Bc1. It is used for control of a range of fungal diseases, including brown rust, tan spot, powdery mildew, and net blotch in cereals, pulses and oilseeds.

ENVIRONMENTAL FATE 

Picoxystrobin is applied to foliage where it rapidly penetrates and is rainfast after two hours. The fraction that is not intercepted by foliage and lands on the soil will be microbially degraded under aerobic conditions with a halflife ranging from 30 to 74 days. It is also degraded on soil by photolysis, with a half life of 12 days; however, photolysis both on soil and in water is limited by the degree of exposure to light. It is ranked as moderately mobile to mobile in soil, but is not generally detected below a depth of 5 cm. With a log Kow of 3.6, it is expected to bind to organic carbon in soil and sediment. Ten field dissipation studies were conducted, two in U.S. soils, two in Canadian soils, and six in European soils. The DT50 ranged from a low of 35 days in Wisconsin sandy loam-loamy soil to a high of 151 days in clay loam-loam soil in Manitoba, Canada. The geometric mean of the DT50s for the ten field dissipation studies was 67 days. In water, picoxystrobin is degraded slowly by photolysis, with a half life of about 29 days. It is stable to hydrolysis. In an aerobic water-sediment system studies, picoxystrobin was degraded with a half life for the total system ranging from 39 to 48 days. Under anaerobic aquatic conditions, the half life was about 84 days for the total system.

Usage: Picoxystrobin is a fungicide belonging to the strobilurin group of chemicals and developed in Syngenta company with preventive, curative and systemic activity for use canola, cereal graints (no rice), dried peas, corn and soybeans.

Application: Picoxystrobin is currently using the best effect of methoxyl acrylic ester fungicide,The foliar diseases prevention and control of wheat and barley,Such as leaf blight, leaf rust, clever blight, leaf spot, powdery mildew, etc.Methoxyl acrylic ester disinfectant is a kind of low toxicity, high efficiency, broad spectrum and systemic bactericide,Almost all of fungi Diseases such as powdery mildew, rust, clever blight, mesh spot, downy mildew, blast, etc all have good activity,And can effectively control the other fungicide resistant pathogens,Protective effect, treatment and eradication, osmosis, no carcinogenic and mutagenic characteristics,Picoxystrobin belong to systemic broad-spectrum fungicide, rooting out, protection, penetration and absorption effect.
