摘要
为实现宁夏枸杞生产的标准化和病虫害防治的规范化,试验以枸杞蚜虫和木虱为防治对象,选用5种新型杀虫剂进行田间防治效果比较试验。结果表明,噻虫嗪、乙基多杀菌素和吡蚜酮对枸杞蚜虫均具有较好的防治效果,施药后10 d的防治效果分别为89.57%、90.51%、87.90%;氟啶虫胺腈的防治效果相对较低,施药后10 d防治效果为69.90%。乙基多杀菌素、顺式氯氰菊酯和氟啶虫胺腈对枸杞木虱的防治效果均显著高于噻虫嗪,且具有一定的持效性。试验各药剂处理对枸杞生长安全,无药害产生,可在枸杞生产中推广与应用。
In order to achieve the standardization of wolfberry production and pest control in Ningxia, wolfberry aphid and Poratrioza sinica Yang ＆Li were taken as the control objects and five types of new pesticides were selected to conduct the comparative test of field control effects. The results showed that thiamethoxam, spinetoram and pymetrozine had better control effects on wolfberry aphid. After 10 days of treatment, the control effect was 89.57%, 90.51% and 87.90%,respectively. The control effect of sulfoxaflor was relatively low. After 10 days of treatment, the control effect was69.90%. With certain persistence, the control effects of spinetoram, alpha-cypermethrin and sulfoxaflor on Poratrioza sinica Yang were significantly higher than that of thiamethoxam. The five kinds of pesticides have no phytotoxicity and bad effects on wolfberry growth, so they can be promoted and applied in wolfberry production.
