Figure 1
Comparison of Jassid densities between nitenpyram applied at ETL and Calendar basis comparison with control. Mean values on sampling dates labeled with sing headed arrow indicates the date of spraying of nitenpyram at calendar basis whereas double headed arrows indicated its application whenever jassid reached to ETL.
Figure 2
Mean okra yield obtained from nitenpyram sprayed (at calendar and ETL basis) and control plots. Bars labeled with common letters are significantly different at P<0.05.
