Plant Bug 1.7 – 2.8 oz/A (0.053 – 0.088 lb ai/A ) Cot. Fleahopper Do not apply more than 2.8 oz/A (0.088 lb ai/A) per application Do not apply more than 3 applications per season Do not exceed 0.267 lb ai/A (8.4 oz/A) per season

17 ©2005 copyright, FMC Corporation. FMC confidential. Consultant Demonstration Objective: Evaluate Carbine 50 WG against a standard pest control program for control of tarnished plant bug in cotton. Treatments: –Carbine: 2.3 oz/A (0.072 lb ai/A) –Grower StandardProduct and rate at discretion of Consultant Trial established according to local threshold levels. Plot Size: Non-replicated commercial production plot of approximately 25 acres, 2 applications

21 ©2005 copyright, FMC Corporation. FMC confidential. Consultants contacted on a weekly basis – Comments: –Aphid Very good control Somewhat slow with good kill between 6-10 DAT –Plant bug Fair to good plant bug control Slow with concerns at 3 DAT Better control evaluations at 6+ DAT with minimal damage observed –No mixing or application problems, no phytotoxicity 2006 Demo Trial Results

22 ©2005 copyright, FMC Corporation. FMC confidential. Summary Carbine provided good control of cotton aphid and plant bug resulting in square retention and yields comparable to that of standards Carbine does not kill insects quickly but the non-feeding effects are clearly demonstrated in yield and square retention data Percentage control and insect counts are not always effective indicators of insecticidal efficacy

23 ©2005 copyright, FMC Corporation. FMC confidential. Resistance Management In 2006 neonicitinoid tolerance was observed in aphid populations from MS and AR (Gore 2006) Organophosphates (Orthene, Bidrin) have minimal early season use due to concerns over aphid flaring and plant bug tolerance Carbine –Alternative to neonicotinoids, unique mode of action –Excellent insecticide early season especially when neonicitinoid seed treatments are used and labels prohibit foliar neonicitinoid applications for 30 days –Recommended as part of a resistance management program in rotation with other insecticides with different modes of action.
