Effects of Weather:
DO NOT spray under a strong temperature inversion, or when temperature exceeds 25 o C as this will result in a reduction in
control. Best control will be achieved when deltamethrin is applied during cooler periods of the day. DO NOT apply within
1 hour of rain.
Restrictions:
• Alfalfa seed production – DO NOT apply more than once per year.
• Canola – May be applied by ground or air. DO NOT apply more than once per season.
• Corn – DO NOT apply more than 3 times per year
• Potato – (Ground) DO NOT apply more than 3 times per year. (Aerial) DO NOT apply more than 2 times per year. May
be used only once per season on high organic (muck) soils.
• Red clover – DO NOT apply by air. DO NOT make more than 2 applications per year. DO NOT use treated crop for feed
or forage. Restricted entry interval – 12 hours
• Wheat, barley, oats, flax, lentil – (Ground) DO NOT apply more than 3 times per year. (Aerial) DO NOT apply more than
2 times per year.
• Storage: DO NOT store below freezing. DO NOT store near feed, food, seeds or fertilizer. Keep away from heat, sparks
and open flames. If stored for 1 year or longer, shake well before using.
• Others:
º Ground application - Observe a 16 yard (15 m) buffer zone from environmentally sensitive areas (for example,
wetlands, sloughs, rivers, houses, farm buildings).
º Aerial application – Leave a 110 yard (100m) buffer zone. DO NOT apply deltamethrin by air when the wind speed
exceeds 8 kph. In soils with high organic content (muck soils), deltamethrin should be applied only once during
each crop year, prior to August 1, and at rates of no more than 80 mL/acre.
Precautions:
Deltamethrin is of high mammalian toxicity and is a severe eye and skin irritant. Avoid contacting or breathing spray mist.
This product contains petroleum distillates which are moderately to highly toxic to aquatic organisms and fish. Deltamethrin
is toxic to bees and other beneficial insects. Avoid spraying when bees are foraging. Wear protective clothing, including
goggles and respirator, when handling or spraying. DO NOT contaminate or store near feed or foodstuffs. Wash thoroughly
after using deltamethrin.
