Deskripsi
Trials conducted in Kern County Thompson Seedless vineyards in 1972 showed that flower thrips nymphs, feeding under persisting caps (calyptras), are associated with the sunburst or starfish scars which have proved troublesome in recent years. The gibberellin sprays used in producing table Thompsons, accentuate this damage.
