N2 - Efficacy of two nonchemical strategies - sprays of the entomopathogenic fungus Beauveria bassiana (Mycotrol® ES) and an exclusion strategy using plastic construction fence - in controlling apical seediness of strawberry fruit (cv. Tristar) caused by tarnished plant bug (TPB) (Lygus lineolaris) was evaluated in a 2-year field experiment in Iowa, U.S.A. Mycotrol® did not reduce incidence of apical seediness significantly (P=0.05) in comparison to an unsprayed control. Incidence of B. bassiana on TPB was >40% in Mycotrol-treated plots compared to 7% in the unsprayed control, however, suggesting that the fungus did not deter activity of the infested TPB. The plastic fence significantly reduced incidence of apical seediness, but also total yield, in 1997, but had no significant effect on either variable in 1998. Incidence of apical seediness was significantly lower in the conventional insecticide treatment (Danitol 2.4EC) than in other treatments.
