These are count of metcalfa colony at 0 DaysAfterTreatment (=> before trt), 2, 7 and 14 DAT (=>three column of data after treatment) First column contain the number of the treatment 1=>check 2=>experimental insecticide @low rate 3=>experimental insecticide @normal rate 4=>experimental insecticide @double rate 5=> Standard insecticide Second column contain progressive number of plot (randomized treatment) Third column contain progressive number of each sub sample. So how can I perform pre-post control following Henderson-Tilton formula that is (1-(insect_in_control_before_trt * insect_in_treatment_after_trt) / ((insect_in_control_after_trt * insect_in_treatment_before_trt))*100 so can anybody suggest me how can I sum every sub sample by each plot(20 data per column) and perform H-T formula? or ABBOT 100*(1-(insect_in_treatment_after_trt / insect in control after trt) tnx in advance ------------------------------------------------------------------------------------------------------------------------- Landini Dr. Massimiliano Tel. mob.
