Where a rate range is given in the Directions For Use, the higher rate should be used when:

  • crop canopy is dense and foliage is inhibiting spray penetration
  • a range of insect growth stages are present (for example 1st through 5th nymphal stages of grasshoppers OR larvae and adults of Colorado potato beetle)
  • insect populations are very high

 

Packaging
8 x 1 L jugs per case

 

Timing
For maximum efficacy, it is necessary to:
- keep crop and pest under observation to be able to spray at the right moment
- ensure that insects are contacted during spraying, especially if they are found on the underside of leaves or if the foliage is very dense
Unless otherwise stated, apply Decis when insects first appear and repeat as required to maintain control.
