EVALUATION OF SELECTED SEED TREATMENTS AND TEMIK IN-FURROW FOR EARLY SEASON PEST CONTROL

Sanders Thrips: Frankliniella spp. Delta and Pine Land NuCotn 33B was planted at a rate of four seed/row ft on a Bruin/Commerce silt loam 8 May. Plots were four rows (40-inch centers) x 45 ft replicated six times in an RCB design. Plots were planted with a John Deere 7100 series planter equipped with seed cone hoppers.

Control of thrips adults and larvae was determined by randomly selecting five plants/plot on 27 May. Whole plant washing procedures were used to remove the insects and counts were made with the aid of a dissecting microscope. Plant density was determined by counting the total number of plants on the center two rows of each plot, averaging and dividing by 45 to determine plants/ft. Plots were mechanically harvested on 9 Oct with a John Deere 9930 spindle-type picker to determine lb seedcotton/acre. Data were subjected to ANOVA and means separated according to DMRT.
