| Abstract | A small-plot trial was conducted at the Red River Research Station, Bossier City, LA, to determine the efficacy of selected insecticides in controlling the bollworm/tobacco budworm (BW/TBW) complex on cotton. The experimental design was a RCB with 4 replications. Plots were planted 9 May and were 4 rows X 100 ft on 40-inch centers. All plots had Temik 15 G (0.5 lb [AI]/acre) applied in-furrow at planting. Prior to trial initiation, plots were oversprayed for cutworms on 6 Jun (Karate 1 EC at 0.025 lb [AI]/acre); boll weevils on 9, 13, 18 Jun and 3 Jul (Vydate C-LV at 0.25 lb [AI]/acre); BW/TBW on 27 Jun (Baythroid 2 EC at 0.03 lb |AI]/acre), and 11 Jul (Karate 1 EC at 0.03 lb [AI]/acre); and for aphids on 17 Jul (Provado 1.6°F at 0.047 lb [AI]/acre). Insecticide test materials were applied on 14, 21, 28 Jul, 5 and 14 Aug in 5.9 gal total spray solution/acre at 60 psi with TX-3 hollow-cone nozzles spaced 20 inches apart (2 noz-zles/row). Treatments were applied with a high-clearance sprayer equipped with a CO2 system for spraying small plots. Infestations of BW/TBW larvae and square damage were monitored on 17, 24, 31 Jul, and 7 Aug by examining 25 squares/plot. Following the trial, all plots were oversprayed for BW/TBW on 22 Aug with Karate 1 EC plus Curacron 8 EC at 0.028 + 0.75 lb [AI]/acre. Boll weevil eradication sprays with weekly applications of ULV Malathion (12 oz product/acre) were begun the week of 18 Aug. Yields were determined by mechanically harvesting the center 2 rows of each plot on 7 Oct. |
