Dynamics of changes in fluorescence of black nightshade plants

Untreated plants

Bentazone alone

Bentazone plus polyglycerol derivative

Bentazone plus organosilicone superwetter

You see the influence of adjuvant on bentazone activity visualized in the photosynthetic efficiency of black nightshade plants.
In the upper-right corner, you see the hours after treatment with a bentazone spray.
The colour table indicates the value of the quantum efficiency of the photosynthesis.
