Chemical Name: Methyl (R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propanoate
Molecular Formula: C₁₈H₁₅ClN₂O₄
CAS Number: 76578-13-7
Common Name: Quizalofop-p-methyl
Trade Name: Methyl quizalofop
Meaning of TC: Technical Concentrate, referring to high-purity pesticide active ingredient
| Characteristic | Quizalofop-p-methyl | Quizalofop-p-ethyl |
|---|---|---|
| Ester Group | Methyl ester (-OCH₃) | Ethyl ester (-OC₂H₅) |
| Molecular Formula | C₁₈H₁₅ClN₂O₄ | C₁₉H₁₇ClN₂O₄ |
| CAS Number | 76578-13-7 | 100646-51-3 |
| Market Application | Rarely used, mainly for scientific research | Mainstream herbicide widely used globally |
Active Ingredient Content: ≥95.0%
Appearance: White to light brown powder
Melting Point: Approximately 84.3-98.6℃
Density: 1.409 g/cm³
Vapor Pressure: 3.34×10⁻¹² mmHg (25℃)
Selectivity: Highly effective against grassy weeds and safe for broadleaf crops
Absorption Mode: Absorbed through the stems and leaves of weeds, with bidirectional translocation in plants
Action Site: Inhibits acetyl-CoA carboxylase (ACCase), blocking fatty acid synthesis
Symptom Manifestation: Necrosis of weed growing points and meristems, leading to whole plant death eventually
Soybeans, peanuts, cotton, rapeseed, potatoes, sugar beets, flax, tobacco
Broadleaf vegetables (e.g., tomatoes, cucumbers, eggplants), fruit trees, forest nurseries
Annual grassy weeds: Barnyard grass, crabgrass, green foxtail, goosegrass, Italian ryegrass, wild oat
Perennial grassy weeds: Reed, etc.
Application Timing: Post-emergence foliar treatment, optimal at the 3-5 leaf stage of weeds
Formulations: TC technical concentrate is not used directly in most cases; it is processed into preparations such as emulsifiable concentrates (EC), e.g., 5%, 10%, 50g/L, 96g/L EC
Application Dosage: Adjusted according to weed species and density, generally 45-60g a.i./ha
Precautions:
Sensitive to grassy crops (e.g., rice, wheat, corn), prohibited for use on them
Avoid drift of pesticide solution to sensitive crops during application
Mixing with other types of herbicides (e.g., broadleaf herbicides) can expand the weed control spectrum
An important variety in the global herbicide market, accounting for approximately 13.6% of aryloxyphenoxypropionate herbicides, with an annual sales volume of about 165 million US dollars
Chinese Standard: NY/T 3594-2020 Quizalofop-P Technical has been issued, replacing HG/T 3761-2004
Manufacturers: Zhejiang Xinnong Chemical Co., Ltd., Shandong Lubang Chemical Co., Ltd., etc.
