Abstract
Logistic equations to describe height and diameter growth of budded, fieldgrown pecan, Carya illinoensis ((Wang.) K. Koch.), nursery stock were developed for several diameter classes of four cultivars—‘Cheyenne,’ ‘Stuart,’ ‘Elliott,’ and ‘Desirable.’ The equations were used to describe impact of feeding on final tree size by larvae of the pecan bud moth, Gretchena bolliana (Slingerland), during May, June, and July. Simulated bud moth damage (pinched terminal buds) occurring in Mayor June significantly reduced both final scion height and diameter of pecan nursery stock. Pecan nursery stock damaged in July was not significantly different (P = 0.05) from the undamaged control in final scion height and diameter. Recommendations to growers based on this study can significantly reduce pesticide use to control pecan bud moth.
