Data were analyzed with ANOVA and ERR_HeadA=ERR_HeadB=ERR_HeadA=ERR_HeadB/HeadA planted in Starkville, MS located on the R.R. Foil Plant Research means were separated using Fisher’s Protected LSD (P ≤ 0.05). ERR_HeadB=ERR_HeadC=ERR_HeadB=ERR_HeadC/HeadB Facility. Plot size was four rows wide by 40 feet in length on 38-inch At the first sampling 18 DAP, all of the insecticide treatments ERR_HeadC=ERR_HeadD=ERR_HeadC=ERR_HeadD/HeadC centers. Field studies were implemented as a randomized complete significantly reduced immature thrips densities compared to the un- block with four replications. All treatments, except Counter 15G, treated check (Table 1). There were no significant differences among ERR_Extract3=ERR_HeadA=ERR_Extract1=ERR_HeadA were applied as a seed treatment. Counter 15G treatments were ap- treatments for densities of immature thrips at 24 DAP. At 24 DAP, plied as in-furrow granules using the standard granular application all of the insecticide treatments significantly reduced thrips damage boxes on a John Deere 1700 planter. Plots were sampled at 18 and compared to the untreated check, with Orthene + Counter providing 24 days after planting (DAP). Each plot was sampled by randomly the greatest reduction in thrips damage (Table 2). At 29 DAP, all of cutting five plants from the center two rows. Plants were washed in the insecticide treatments reduced thrips damage compared to the the lab with a bleach and soap solution to dislodge thrips onto filter untreated check. Orthene + Counter, Counter, and Aeris resulted paper and counted with the aid of a dissecting microscope. Damage in significantly greater reductions in thrips damage compared to ratings were taken at 24 and 29 DAP by assessing the average plant Orthene or Avicta Duo. Orthene + Counter resulted in significantly damage of the whole plot on a scale of 0–5 with 0 being no damage higher yields compare to any of the other treatments (Table 3). Table 1. Table 2.
