Herbicide Properties and Technical Advantages
1. Mechanism of Action: Inhibits plant shikimate synthase, disrupts protein metabolism, and kills weed roots through systemic uptake.
2. Applications:
Weed control between rows in non-arable land and orchards
Low-Temperature Adaptability: Effective above 3°C (better than the 15°C low-temperature limit of glyphosate ammonium)
3. Weed Control Characteristics:
Broad-Spectrum: Effective against grasses, sedges, and some broadleaf weeds (such as Cyperus rotundus).
Fast-Acting Effect: Effective within 3-7 days, faster than glyphosate alone (7-10 days).
Combination Advantages: Often combined with sodium 2-methyl-4-chloropropane (trade name "dimethyl glyphosate") for enhanced control of broadleaf weeds.
Safety and Environmental Characteristics
1. Residual Life: Degrades rapidly in soil, but subsequent broadleaf crops (such as crucifers) require a planting interval of several months.
2. Environmental friendliness: Low residue, easily inactivated by metal ion binding.
3. Commercial status: One of the most widely used glyphosate salts globally, Xinan Group achieved the first registration of a technical in China.
