Abstract

Summary The effects of EDTA (ethylene diamine tetraacetic acid), Kresoxim‐methyl, Wettable Sulphur 80 WP and the surfactants Triton X‐100, Triton X‐114, Dehydol TA 5 and Dehydol TA 29 on pollen tube growth of Malus domestica , Borkh. cvs ‘Golden Delicious’ and ‘Mondial Gala’ were determined by image analysis. The ED 50 ‐ and ED 90 ‐ values (effective doses giving 50% and 90% reduction of growth) of the chemicals, except for the surfactants, were determined. The selected test substances showed an inhibiting effect on pollen tube growth, with Kresoxim‐methyl being the most active. Surfactants are components of pesticides and they also caused inhibition of pollen tube growth but only at application rates more then 10‐fold higher than typically recommended. Pollen of both apple cultivars were almost equally sensitive to the chemicals.
