expression of herbicide symptoms may be reduced as weeds hardened off by drought are less susceptible. Aim EC
can be applied only one time per growing season.
How it Works
Rapidly absorbed by foliage. Inhibits the PPO enzyme involved in chlorophyll and heme synthesis. This action
results in leaky cell membranes and rapid browning and death.
Expected Results
Initial symptoms are observed within hours and death occurs within a few days.
Restrictions
Rainfall
:
Avoid application when heavy rain is forecast. Heavy rainfall shortly after application may reduce weed
control.
Pre-harvest Interval
:
Wait 3 days before harvest except for potatoes which require 7 days.
Grazing
:
DO NOT graze the treated crop or cut for feed.
Re-cropping
:
There are no rotational restrictions 12 months after application.
Environmental Precautions
Recommended buffer zone of 5 metres from any sensitive habitat without the use of any drift control aids.
Toxicity
Acute oral LD

(
