Data from field tests conducted across the cotton belt in 1993 have been compiled to evaluate OVASYN's commercial performance alone or in combination with other cotton insecticides. OVASYN application rates ranged from 0.125 to 0.25 lb ai/A. Data indicate that OVASYN alone exhibited very good alternative chemistry ovicidal activity against tobacco budworm, Heliothis virescens, and bollworm, Helicoverpa zea, eggs. Data also indicate that the addition of OVASYN (1) improved activity of pyrethroids against beet armyworm, Spodoptera exigua, (2) improved activity of thiodicarb against beet armyworms and (3) improved activity of dicrotophos against cotton aphids, Aphis gossypii. At one trial site, OVASYN alone at 0.125 lb ai/A produced cotton aphid mortality of over 40%. In the majority of trials, where yield data was obtained, OVASYN produced an improved cotton yield response. At a rate of 0.25 lb ai/A, OVASYN proved to be very safe to the beneficial population consisting of Western big-eyed bug, Geocoris pallens, common damsel bug, Nabis americoferus, minute pirate bug, Orius tristicolor, common green lacewing, Chrysopa carnea, syrphid fly, Allograpta abliqua, and green lynx spider, Peucetia viridans.
