摘要：

Two experiments were carried out to examine the role of cultivation practices and pre-treatment of tubers with sodium hypochlorite (NaOCl) in suppressing the damage caused by blackleg disease (Erwinia carotovora) and by potato tuber moth (Phthorimea opercullela) to potato crops in the Sultanate of Oman. Increasing the planting depth of tubers was found to cause a significant reduction in the level of tuber moth infestation in harvested tubers. Pre-treating infested and uninfested tubers with NaOCl had a significant impact upon the incidence of blackleg in the subsequent crop. In addition, seed that was infested with tuber moth showed higher levels of blackleg damage in the subsequent crop. However, this difference was not statistically significant. Overall, the data indicate that pre-treatment with NaOCl and the manipulation of tuber planting depth may make a significant contribution to blackleg and tuber moth suppression within potato production.
