Incidence of scab and foliage condition on pecan cultivars grown without fungicide or insecticide sprays in a humid region
HortTechnology 13 (2), 381-384
Abstract: Fourteen pecan (Carya illinoensis) clones with desirable traits selected from preliminary screenings were evaluated for scab resistance, foliage condition and foliage retention. No fungicide or insecticide sprays were applied in order to increase pest and disease pressure and to better assess suitability of the selections for low input plantings. Most clones were equal to or better than 'Elliott', the resistant standard cultivar and were superior to 'Desirable', the susceptible standard cultivar, in scab incidence and foliage condition.
