Key Messages

• The effect on yield was comparable to the effect on the number of affected tillers.
• All of the seed applied insecticides reduced the number of affected tillers.
• The greatest effect on yield was detected with Pontiac, Evergol Energy + Gaucho and Vibrance + Cruiser 350FS. Evergol Energy and Gaucho had the highest yield effect and the highest reduction in tillers affected.
• Yields varied from 1.9 tonnes per hectare to 2.374 tonnes per hectare.
• The proportions of affected tillers ranged from 0.24% (Evergol Energy + Gaucho) to 28% (untreated).
