| Summary: | To minimise herbicide inputs, reduce environmental burdens, and delay the evolution of herbicide resistance, it is of the utmost significance to study the interaction between herbicides. This may be accomplished by selecting the optimal combination, which, through synergy, delivers more cost-effective weed control than a single herbicide. Under laboratory conditions, interactions between binary mixtures of bensulfuron, propanil, 2,4-D, or bentazon on chlorophyll reduction of Lemna minor were investigated using the Additive Dose Model. Mixtures of propanil/2,4-D resulted in low antagonism whereas strong antagonism was evident in bensulfuron-methyl/propanil. Combinations of bensulfuron/bentazon and bensulfuron/2,4-D led to moderate antagonism. By contrast, propanil in combination with bentazon demonstrated a modest degree of synergism. The findings of this study could provide good guideline and insights when mixing two herbicides for weed control in rice fields and other aquatic environment. |
