Abstract:

In the present study adsorption-desorption behaviour of penoxsulam on six different Indian soils at different temperatures (15, 25 and 35⁰C) and varied ionic strengths (0.003 and 0.03M) was investigated to evaluate the effect of penoxsulam adsorption and desorption in varied soils. An increase in temperature decreased the adsorption but increased desorption of the herbicide in soils whereas on increasing the ionic strength adsorption increased effectively and desorption decreased from soils. Alkaline and neutral soils (JK-1, BD-2 and HLD-2) showed significant difference in adsorption whereas in acidic soils (LOH, HLD-1 and BH-1) this difference was only minor. Adsorption-desorption data showed statistically significant difference (p≤ 0.05) at different temperatures. An increase in ionic strength showed significant difference in adsorption of the neutral and basic soils (JK-1, BD-2 and HLD-2) but in acidic soils (LOH, HLD-1 and BH-1) this difference in adsorption was minor, though desorption depicted statistically significant difference (p≤0.05) in all the six soils.
