Application Information
Agricultural uses
:
Apply with g
round or by air.
Water
volume
:
Ground 20 - 80 L/acre. Air - 12 L/acre.
Industrial Uses
Apply with power equipment, knapsack sprayer or by air. Note: Do not apply by air on roadsides.
Water Volume
:
Broadleaf weeds - 80 - 220 L/acre. Brush control: 300 - 500 L/acre.
When to Apply
:
Broadleaf weeds: Apply during the month of May or in early fall. Some species may require a
second treatment. Spray weed infested areas with an even spray pattern, making sure weeds shielded by high grass
are thoroughly wetted. Spray tall weeds to runoff. Brush control: Apply on foliage and stems just before or just after
brush is in full leaf in late spring or early fall. Many species may require re-treatment the following year.
Basal treatment (not ash or basswood): Any time of year. Frill treatment
:
Standing trees more than 13 - 15 cm in
diameter.
Stump treatment:
Immediately after cutting.
Application Tips
Crops under stress from adverse environmental conditions such as excess moisture, drought, disease, etc. may suffer
a further setback when Dichlorprop + 2,4-D is applied; however, the crop injury that may occur is usually offset by
the benefits of enhanced weed control. Apply in warm weather when the crop and weeds are growing well and the
weeds are at a susceptible stage. Avoid application during drought conditions or during exceptionally hot weather.
How it Works
A systemic herbicide absorbed by leaf and stem.
Expected Results
Twisting and curling of weeds will commence 2 - 10 days after application. Growth ceases; eventually plants turn
brown and die. Poor results may be expected if poor coverage or low relative humidity during and after spraying.
Restrictions
Rainfall
:
Rain within 3 or 4 hours of application may reduce control.
Grazing
:
Do not graze or cut treated crops for forage until 40 days after application. Withdraw meat animals from
treated fields at least 3 days before slaughter.
Environmental Precautions
2,4-
D + dichlorprop formulations are moderately to highly toxic to aquatic organisms. These formulations are also
toxic to small mammals, birds, aquatic organisms and non-target terrestrial plants. Do not allow spray to drift onto
sensitive plants. Do not spray exposed roots of trees and ornamentals. Observe buffer zones specified on the label.
Runoff
:
To reduce runoff from treated areas into aquatic habitats, avoid application to areas with moderate to steep
slope, compacted soil, or clay.
Leaching
:
The use of these formulations may result in contamination of groundwater, particularly in areas where
soils are permeable (e.g. sandy soil) and/or the depth to the water table is shallow.
