* Not recommended as a standalone treatment for thrips control.
** Radiant SC is suggested if western flower thrips are present in significant numbers. The use of an adjuvant is recommended when using Radiant SC or Intrepid Edge for control of thrips, although several herbicides that are commonly co-applied with thrips application can act as an adjuvant.
*** Tobacco thrips resistance to organophosphate insecticides is increasing, use with caution.
**** General rating for typical thrips control vs. rating specific for western flower thrips (WFT).
- It is generally best to make any foliar insecticide applications by the second leaf stage. More than one foliar insecticide application is rarely justified.
- A preventative foliar application is often suggested under adverse growing conditions such as cool weather.
