Summary: Trails with glyphosate spred onto the soil around profusely suckering apple cherry pear and plum trees so as to wet the suckers, were carried out at ballygagn. Are East malling Kent; Long ash tom, Bristol and Loughall N Ireland Trees were sprayed to simulate normal weed killing in winter when the suckers were dormant, in April when the sucker buds had recently burst and in june when the sucker were in full leaf no damage was cused to the parent trees in the year of treatment or the following year in any of the trails. No glyphosate residues (< 1ppm) were found in the leavws of the parent apple tree at all soles sucker deths or damage was greater and apple trees. At all sites sucker death or damage was greatest and re grow the least with the full leaf spray. Damage was greater with the April than the January cpray Sucketrs of the different kinds of from varied in susceptibility ot glyphosate There was no damage ot the parent trees at long Ashton when suckers were sparyed to run off in July
