2,4-D + MCPA 67.5% SL

Post-emergence, hormone-type, systemic, selective herbicide – growth regulator

Trade name: U-Kombi Fluid 46
Chemical family: Phenoxycarboxylic Acids

Mode of Action

This herbicide mimics auxin, a natural plant growth-regulating hormone.
By disrupting normal hormonal balance, it inhibits growth in susceptible broadleaf weeds and causes uncontrolled cell division, ultimately leading to weed death.

Application Management

• Do not use on newly planted clover and other legumes.

• Apply on cereals in spring when the leaf sheath becomes visible.

• Wheat and barley can be sprayed from the 5-leaf stage up to before first node appearance.

  • Last spraying time: before first node formation.

• Drift may cause serious injury to broadleaf crops in neighboring fields, especially:

  • Sugar beet, cotton, cabbage, vegetables, celery, pear orchards, vineyards, etc.

• Best results are obtained when weeds are treated early in the growth stage.

• Avoid application on crops under stress, not actively growing, or during cold/dry weather or before rainfall.

• Do not apply in the period immediately before or after planting other crops.

• Effective at low rates; higher rates can cause crop injury.
