 For example, John Daly, agricultural instructor and later father of the RTÉ gardening expert Gerry Daly, had invited him several times, starting in 1959, to come and lecture to the fruit growers in County Wexford on his research into weed control.As a result of these trips he was offered in October 1963 a post as Director of Horticultural Research at the Kinsealy Research Centre, a facility of the Agricultural Research Institute (now a Teagasc facility), at Kinsealy north of Dublin, Ireland.He had won a Fulbright Grant to spend some further time in the US, but despite this and ongoing projects, he eventually accepted the offer, taking up the new post in May 1964, moving to live in Ard na Mara, Malahide.
