Herbicides
Mixing Instructions
When using Dyvel + clodinafop propargyl, add Dyvel first, then the clodinafop, then the adjuvant (where required).
Application Tips
Best under good growing conditions and air temperature 10 - 25°C. Avoid application when crop is under stress from
disease or adverse environmental conditions. Avoid application if frost or severe drop in night temperature is forecast.
Crop damage can occur if the chemical is applied at any time other than the recommended crop stage. Shortening of
straw may occur without loss in yield.
How it Works
DyVel is a systemic herbicide absorbed through the roots and leaves and translocated readily.
Expected Results
Weeds: Twisting, bending of main stem and leaf petioles, cupping of leaves or increase in root size occur within 10 -
14
days. Poor results may be expected if older weeds are sprayed or if less than recommended water volume is used.
Restrictions
Rainfall
:
Rainfall within 4 hours of application may reduce activity.
Grazing Restrictions
:
Do not harvest forage or cut hay within 30 days after application. Do not permit lactating
dairy animals to graze fields within 7 days after application. Withdraw meat animals from treated fields at least 3
days before slaughter
Pre-harvest Intervals
: 60
days.
Re-cropping
:
No restrictions the year after treatment.
Environmental Precautions
DyVel is toxic to aquatic organisms and non-target terrestrial plants. Leave a 15 m buffer zone between last spray
swath and sensitive wildlife habitats such as shelterbelts, wetlands, sloughs, and woodlots.
Surface Runoff
:
Avoid applying this product when heavy rain is forecast.
Leaching
:
This product can leach where soils are permeable (e.g. sand, loamy sand and sandy loam soils) and/or the
depth to the water table is shallow.
Toxicity
Low acute mammalian toxicity. Acute oral LD
50
(
rats) = dicamba 2,629 mg/kg, MCPA = 700 mg/kg. Non-toxic to
birds, fish and bees. May cause burns and can be absorbed through the skin.
Storage
Protect from freezing, but if frozen, no activity is lost if completely resuspended.
