Abstract
The occurrence of apical seediness in strawberries as a result of plant bug feeding is a particularly serious problem in New York State. The role of plant bugs in the production of apical seediness in strawberries was confirmed by the application of effective insecticides. Although several plant bug species may be involved, the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), appears to be the most important in New York State. Tests were conducted in a series of specially designed Latin-square plantings of the Geneva everbearing strawberry variety. Of 11 materials tested, a DDT-endosulfan program appeared to be the most promising when the factors of registration and bee toxicity are considered. Of the newer materials, Azodrin® (dimethyl phosphate ester with 3-hydroxy- N -methyl-cis-crotonamide) provided exceptionally good reductions in fruit injury. Application of the plant hormone NAD (napthylacetamide) failed to correct damage induced by plant bug feeding. The occurrence of pronounced edge effects was observed and the importance of plot design was noted.
