The influence of Betanal 160 EC, applied alone and in combination with the
adjuvants Olejan and Olemix, on soil respiration was investigated. Betanal
caused a decrease of the CO2 production, especially at high dosages. The ad
juvants had no effect on the soil respiration. Applying Betanal in combinat
ion with the adjuvants changed the effect of the herbicide only insignifica
ntly.
