KARATE^® was evaluated for boll weevil control in cotton in nine small plots, replicated trials from Alabama to Texas. Comparisons were made with BAYTHROID^®, ASANA XL GUTHION^®, and untreated checks. Seasonal means across all trials with direct comparisons showed KARATE^® at 24% weevil damaged squares compared with 40% for the GUTHION^® standard and 61% for the untreated checks (Table 1). In direct comparisons with other synthetic pyrethroids, KARATE^® and BAYTHROID^® were equally effective and superior to the untreated check (Table 2).

In a trial conducted primarily as a Heliothis evaluation at Flowers, Mississippi, boll weevil damage was also evaluated. Synthetic pyrethroids were applied four times. All plots were oversprayed as needed (12) with GUTHION^® and/or Methyl Parathion, representing a typical program for this area. KARATE^® and BAYTHROID^® gave equal seasonal boll weevil damage means that were slightly superior to ASANA XL^® and the OP checks (no pyrethroids) (Table 3).

KARATE^® provided excellent boll weevil control in nine trials across the Mid-South. KARATE^® was equal to BAYTHROID^® and superior to other compounds tested.
