CHESS® is an insecticide for the control of Aphids on Lettuce, Potatoes, Tamarillos, Tomatoes, Vegetable Brassicas and Green Peach Aphid on Peaches and Nectarines, and Whitefly on Tamarillos and Tomatoes.
Apply as a broadcast spray in sufficient water to give complete coverage without runoff. This is assisted by the addition of a non- ionic wetting agent. Application to wet foliage will reduce effectiveness.
Lettuce Aphids

Recommended dose
400 g/ha
Maximum number of applications
3 per crop
Pre Harvest Interval (PHI)
7 Days
Stage of use
Apply at first sign of insect presence especially before populations build up and before the head formation of certain lettuce varieties. Repeat if necessary 7 to 14 days later. The closer interval is recommended under high Aphid pressure.
Nectarines

Comment
Apply as a high volume to give complete coverage to the point of run-off. For concentrate spraying, adjust dilution rate accordingly. Complete spray coverage of the foliage is necessary and this will be assisted by the addition of a non-ionic wetting agent.

Recommended dose
20 g/100 litres
Maximum number of applications
1 per crop
Pre Harvest Interval (PHI)
28 Days
Stage of use
Make a single application either at the first sign of Aphid presence or alternatively during crop development when an IPM threshold monitoring system indicates the Aphid threshold level is exceeded.
