Azoxystrobin Usage And Synthesis

Description

Azoxystrobin is a second broad-spectrum strobilurin fungicide (28,29). It forms white solids with a mp = 116 ?C; vp = 1.1 × 10?7
mPa at 25 ?C; logP = 2.5 at 20?C; water solubility = 6 mg/L; and a half-life of 11 to 17 days for aqueous photolysis.

Chemical Properties

White to beige crystalline solid or powder.

Uses

Strobilurin fungicide; inhibits mitochondrial respiration by blocking electron transfer between cytochromes b and c1. Agricultural fungicide.

Agricultural Uses

Fungicide: Azoxystrobin has been processed as a Reduced Risk pesticide for Turf uses. Azoxystrobin is a systemic, broad-spectrum
fungicide that was first introduced in 1998. It inhibits spore germination and is used on grape vines, cereals, potatoes, apples,
bananas, citrus, tomatoes and other crops. Largest crop uses in California are on almonds, rice, pistachios, wine grapes, raisins
and garlic. Among the diseases it controls are rusts, downey and powdery mildew, rice blast and apple scab. A U.S. EPA restricted
Use Pesticide (RUP)

Safety Profile

Moderately toxic by inhalation.When heated to decomposition it emits toxic vapors ofNOx.

Toxicity evaluation

Azoxystrobin has an acute oral LD50 > 5,000 and an acute dermal LD50 > 2,000 mg/kg in rats. Azoxystrobin gives only slight skin
and eye irritation and is nonmutagenic and nonteratogenic. Its NOEL is 18 mg/kg bw/day. It has no toxicity to birds in acute
studies (LD50 > 2,000 mg/kg). It is harmless to other nontarget organisms (honey bees, earthworms, beneficial arthropods) due to
low toxicity and rapid degradation in the environment, which minimizes exposure.
