Effects of Nemacur on the growth of newly planted fruit trees

Abstract

Five trials were conducted over 2 years to investigate the effects on growth of the nematicide Nemacur (400 g/litre fenamiphos) applied as a bareroot dip on four species of deciduous fruit trees, including nectarines, apricots, apples, and cherries. Nemacur concentrations of 0.1, 1.0, and 5.0% in solution (400, 4000, and 20 000 ppm a.i. respectively) were used in combination with dipping times of 10, 15, and 30 min. No change in growth was observed in apples or apricots bare-root dipped at any of these concentrations. However, growth retardation was observed in cherries at the 1.0% concentration, and in nectarines at all concentrations.
