Water volume: Aircraft: 4 L/ac minimum. Ground: 12
L/ac minimum.
XLR-PIus: Dilutions greater than 1:39 will reduce washoff
50W: Aircraft: 4-14 L/ac; Ground: 11-14 L/ac. Climbing
cutworms: Corn - 89-142 L/ac; Forages, cereals: 229 L/ac
minimum; Potato: 91-111 L/ac.
80S: Corn, potatoes: use sufficient water to obtain full
coverage; Climbing cutworms: 89-111 L/ac. Forages, cereals:
22-178 L/ac; Climbing cutworms: 223 L/ac minimum.
All crops: Use sufficient water to obtain thorough and
uniform coverage of spray depending on equipment, severity of
infestation and stage of crop growth.
Low volume air applications: Hot, dry conditions may cause
excessive evaporation of droplets. A higher spray volume per
acre may be required under hot, dry conditions and when crop
canopies are particularly dense.

Nozzles: Low volume applications:
Wettable powder: 50-mesh or coarser screens in entire system;
cone type nozzles, No. 3 or larger.
XLR-PIus: 50-mesh, in-line strainers and 25-mesh, slotted
strainers behind the nozzle; cone type nozzles, sizes D6-45 or
Note: Flat fan nozzles may be used but care should be taken
as excessive droplet breakup and resulting production of fine
droplets may occur. Flat fan nozzles are also prone to
plugging under hot, dry conditions.

7. Application Tips: Timing and good coverage are
essential for effective control. Calibrate spray
equipment to deliver the required volume. Agitate,
stir or recirculate all carbaryl formulations prior to
Corn: Treat entire plant for larvae in whorls or
on foliage. Spray in a 25-30 cm band over the row for
climbing cutworms. Apply at 24 day intervals, if
necessary, for insects attacking silks and ears; start
when first silks appear and continue until silks begin
to dry (3 or more applications may be needed).

Alfalfa weevil: If pre-treatment damage is extensive,
cut and make application to stubble.

8. How it Works: A carbamate insecticide which works by
contact and ingestion. Moderate to rapid in speed of
action with short to moderate residual effectiveness
(2 days to 4 weeks) depending on crop/pest complex,
formulation and climatic conditions.

Expected results: Some immediate control is expected but the
majority of control occurs 24-48 hours after application.

Effects of rainfall: Do not apply just before rain.
XLR-Plus: Maximum resistance to wash off is obtained in the
range of 1:1-1:39 (XLR-Plus:Water) dilution.
50W/80S: Do not apply to wet foliage or when rain or high
humidity is expected within 2 days.

Movement In soil: None.

9. Grazing, Cropping and Other Restrictions: Pre-harvest or
pre-grazing interval(days): Barley, oats, rye, wheat (14);
corn (1); potatoes (7). Alfalfa, clovers, forage grasses,
pasture, rangeland, non-crop areas (0).
Remove cattle from area to be sprayed. Cattle may graze
immediately after application. Treated forage and feed crops
may be fed to dairy animals and animals for slaughter
provided sprays are applied as directed.

10. Toxicity: Moderate acute mammalian toxicity. Acute
oral LD50 rats (mg/kg) = (540). Although carbaryl is toxic to
honey bees, Sevin XLR and XLR-Plus have a reduced honey bee
hazard warning; do not apply directly to foraging bees.

11. Precautions, First Aid: Can be absorbed through the
skin. Ensure the residue on the plants is dry before foraging
commences. Protect yourself by reducing skin and eye
exposure. Wear coveralls, brimmed hard hat, goggles,
respirator, unlined nitrile or neoprene gloves, and neoprene
overboots or rubber boots. In addition wear a waterproof
apron when handling the pesticide concentrate. Follow
directions for Cleaning of Clothes and Equipment before
reuse. If in eyes or skin use standard first aid measures.
If swallowed seek medical attention.

Symptoms of poisoning Salivation, tearing, urination,
defication, pinpoint pupils, muscle spasms, general muscular
weakness, nausea, prostration, convulsions.

First aid: If in eyes or on skin use standard first aid
measures. If swallowed seek medical attention.

For physician: Carbaryl insecticide is a moderate,
reversible, cholinesterase inhibitor. Atropine is antidotal.
Do not use 2-PAM opiates, or cholinesterase inhibiting drugs.

12. Storage: Do not store where temperature frequently exceeds
38 degrees C. All formulations will withstand freezing.
