Abstract: Field investigation was carried out during 2018 at Agricultural College and Research Institute, Madurai, to study the effect of herbigation through micro sprinkler on weed flora, weed dry weight and weed control efficiency. The field experiment was laid out in randomised block design with nine treatments. The pre emergence herbicides of pendimethalin and oxyfluorfen were applied each at three different doses (100, 125 and 150% of recommended dose) in the non-cropped field and its weed control efficiency were worked out. The highest weed control efficiency of 80.8 per cent was obtained in pre emergence application of oxyfluorfen 0.188 kg a.i ha‑1 (150%) through micro sprinkler and the lower weed control efficiency was obtained in weedy check (0.0 %). The lowest weed density and dry weight were recorded in the same treatment. Increased dose of herbicide application resulted in lesser weed density, weed dry weight and higher weed control efficiency. Among the herbicides tried oxyfluorfen performed better in terms of weed control than the pendimethalin. Further, results revealed that weed density and its dry weight obtained under 100 % of recommended dose applied as herbigation through micro sprinkler was at par with conventional method of spraying.
