Abstract
The paper deals with the variations in the toxicity of 2,4-D to Cyprinus carpio at different temperatures during different seasons of the year. The higher temperature has higher toxicity and vice versa at the same concentration. The TLm values indicate that there is a 7–7.5 fold increase in toxicity with the rise in temperature from 17°C in February (winter) to 39°C in May (summer). These results have significance in manipulating the 2,4-D doses for the eradication of aquatic weeds in different seasons.
