Early-Season Insect Control with Provado in the Mississippi Delta

Alan Hopkins, Fred Donaldson


Provado 1.6 F was registered for use in cotton for the 1995 growing season. University research and extension personnel, consultants and Bayer development and sales representatives were involved in testing and demonstrating the product during its first use season. Low tarnished plant bug infestations in the Mississippi Delta limited extensive testing for that pest. However, some experiments and demonstrations did indicate good to excellent control of tarnished plant bug. Cotton aphid infestations were unusually high during 1995. Several experiments initiated for plant bug control provided excellent insight into the control of cotton aphid with Provado, as these treatments delayed or prevented severe aphid infestations. Provado also provided good to excellent control of cotton aphid when used after the population was established (81% control averaged over 22 trials). In four Delta Region experiments where yield data were collected, multiple applications of Provado provided a 13.8% yield increase over the check or standard. Over 70 Consultant demonstrations were conducted. Consultant observations were overwhelmingly positive with 80% satisfied or very satisfied with Provado for aphid and plant bug control. Most consultants reported Provado as easier on beneficial insects than standard treatments. University personnel, consultants and Bayer personnel documented improved square retention where Provado was used as an early-season treatment.
