Application Information
How to Apply
:
Ground and aerial application.
Water volume
:
Ground: 12 L/acre minimum. Aerial: 4 L/acre minimum.
Application Tips
Timing and good coverage are essential for effective control. Sevin XLR applications are more resistant to wash-off
when applied as a concentrated suspension. To ensure wash-off resistance, apply dilutions 1 part Sevin XLR to no
greater than 39 parts water. Application should be made to dry foilage to maximize wash-off resistance.
How it Works
A carbamate insecticide that works by contact and ingestion. Moderate to rapid in speed of action with moderate to
long residual effectiveness (2 days to 4 weeks) depending on crop/pest complex, formulation and climatic conditions.
Some immediate control is expected, but the majority of control occurs 24 - 48 hours after application.
Restrictions
Rainfall
:
Do not apply just before rain.
Grazing
:
Forage and feed crops, including bean vines, hay, pea vines, may be grazed or harvested for use as feed for
dairy animals 48 hours after treatment and meat animals 24 hours after treatment without resulting in illegal residues
in milk or meat. Remove cattle from area to be sprayed. Treated forage and feed crops may be fed to dairy animals
and animals for slaughter provided sprays are applied as directed. Beef cattle may be re-introduced to range 1 day
after application; dairy cattle 2 days after application.
Pre-harvest Intervals (days)
:
Barley (28), oats, rye, wheat (14), peas (3), beans (5), corn (1), potatoes (7), alfalfa,
clovers (2), forage grasses, non-crop areas, pasture, rangeland (1).
Environmental Precautions:
Do not apply when weather conditions favour runoff or drift. Do not contaminate surface or ground water by
cleaning equipment or disposal of wastes, including equipment wash water. Do not apply directly to water or to areas
where surface water is present. Do not allow product into surface water, drains or ground water.
Drift
:
Do not apply or allow to drift to blooming crops or weeds if bees are visiting the treatment area.
Toxicity
Sevin XLR has a moderate acute mammalian toxicity. Acute oral LD
50
(
rats) = 699 mg/kg. Acute dermal LD
50
(
rats) = > 4,000 mg/kg. Highly toxic to bees.
Storage
Do not store where temperature frequently exceeds 38°C. All formulations will withstand freezing.
