Fruit, Set of `Success' Pecans Unaffected by Triphenyltin Hydroxide Fungicide Sprays during Pollination

Abstract

Triphenyltin hydroxide fungicide sprays were applied at 114, 455, or 910 g·ha -1 either 0, 1, 3, 5, or 10 times during pollination of `Success' pecans [Carya illinoensis (Wangenh.) K. Koch]. Pretreatment flower counts were compared to post-treatment fruit counts 7 and 9 weeks after pollination to determine if chemical rate or application frequency affected fruit set. There were no significant differences among rates, application frequency, or combinations in fruit drop ( P > 0.35 in all cases). indicating that spraying this chemical did triphenyltin hydroxide (fentin hydroxide).
