  • Particularly effective on lepidopteran insects (flea beetle, diamondback moth, Bertha armyworm, cutworm and grasshopper)
  • Fast-acting control
  • Easy-to-use liquid formulation; pours and mixes easily
  • Low application rates, less product to handle and fewer containers to dispose of
  • Registered for both ground and aerial application
  • Short pre-harvest interval
  • Safe on crops, regardless of a plant's development stage
  • Tank-mixable with many leading herbicides, including Puma120 Super, Buctril® M, 2, 4-D and MCPA
  • Wide temperature range, unlike many insecticides, Decis provides excellent control even at low temperatures

Application Tips


Timing
Decis is a contact insecticide. For best results, spray when insects are actively feeding
Decis is one of the safest insecticides on beneficial insects, if spraying is required when bees are present, apply in the evening when bee foraging is minimized

 

Crop Insect   Rate     Acres/
2.4L
Jug
Canola, Mustard Diamondback Moth Ground: Apply when larvae are present and actively feeding. Decis 5EG controls only those insects present. Use the higher rate when infestations are high or canopy is thick. 60 mL/ac. in 10 gal. of water per acre 40
Bertha Armyworm Aerial: Apply once per season, when insects are present. Apply when insects are actively feeding. For heavy infestations, use the higher rate. 60 mL/ac. in 1 - 2 gal. of water per acre 40
Flea beetle Ground: Apply when insects are present. Application should be made when the beetles are actively feeding. 60 mL/ac. in 9 gal. of water per acre 40
Aerial: Apply once per season by air, if required. Apply when insects are present. Application should be made when the beetles are actively feeding.   40
Cabbage Seedpod Weevil Ground: For control of adult weevil only. Apply once per season when adults are seen on flower buds or developing pods. Must apply prior to egg laying. 80 mL/ac. in 10 gal. of water per acre 30
Grasshopper Ground: Apply when insects are present as young hoppers or signs of insect damage are evident. Apply when the grasshoppers are in the 2 - 4 nymphal stage. Best control will be achieved when application is mage prior to wing development. Under severe insect pressure, application should also be made to a 15-meter strip along fence rows around the field. The higher rate should be used when the proportion of mature and late nymphal stages in the population is high and spray penetration is inhibited by dense crop canopy. 60 mL/ac. in 10 gal. of water per acre 40
Aerial: use as directed 60 mL/ac. in 1 - 3 gal. of water per acre 40
Wheat, Barley, Oats, Flax, Lentils, Rangeland, Pasture, Roadsides Grasshopper Ground: Apply when insects are present as young hoppers or signs of insect damage are evident. Apply when the grasshoppers are in the 2 - 4 nymphal stage. Best control will be achieved when application is mage prior to wing development. Under severe insect pressure, application should also be made to a 15-meter strip along fence rows around the field. 60 mL/ac. is recommedned for optimal control. 60 mL/ac. in 9-18 gal. of water per acre 40
Aerial: use as directed 60 mL/ac. in 1 - 2 gal. of water per acre 40
Cutworm Ground or aerial: Apply once per season when larvae are present and feeding. Do not disturb the soil after application. Under severe insect pressure, application should also be made to a 15 meter strip along fence rows around the field. DO NOT APPLY TO ADJACENT CROPS 80 mL/ac. in 10 gal. of water per acre 30

 

Economic Thresholds



  • It is important to protect the canola plant during its early stages of development as this is when most flea beetle damage occurs.
  • Canola seedlings can withstand 50% leaf loss. However, the economic threshold for control is 25%. Beyond 25%, leaf damage can reach a level where plant development and yield are substantially reduced.
  • If a foliar insecticide is required, Decis provides excellent control.

Application Tips



  • Scout your fields often to ensure proper application and timing
  • Scouting should take place in the early morning or in the evening when insects are actively feeding
  • Use sufficient water to ensure thorough coverage. More water may be required when dense foliage is present.

 

Pre-harvest intervals:

  • Canola - 7 days
  • Wheat, barley and flax - 40 days
  • Oats - 31 days
  • Lentils - 30 days
  • Rangeland and pasture - no PHI (rangeland beef and dairy) may be fed or allowed to graze on Decis-treated crops
