Abstract

Abstract:

【Objective】 To clarify the occurrence rule of walnut cancer disease and reduce the concentration of chemical pesticides in the prevention and control process.【Methods】 A survey of walnut cancer disease was carried out in 6 sample plots in Buzhake Township,Hetan County,Hetan,prefecture Xinjiang from April to August 2022 through five-point sampling method.Two chemical agents optimized in the early stage:40% Tebuconazole & Prochloraz EW and 1.6% benziothiazolinone PF,and two adjuvants:noposion Toucui bark penetrant and SK EnSpray 99 were applied in 10 different treatments.After application,the recurrence and healing of the spots were observed,and the efficacy prevention,the correction anti-effect and the mean healing width were calculated.【Results】 The results showed that there were two peak periods of walnut cancer disease in Buzhake Township,Hotan County,Xinjiang in May and August in 2022.The pathogen invaded mainly through the sawing edge,accounting for 44.1% of the total number of spots.The number of spots on the sunny side was the most.The control effect of 40% Tebuconazole & Prochloraz EW reduced by 30%(1,428 times of solution)+ Toucui 100 times of solution and 1.6% benziothiazolinone PF reduced by 50%(400 times of solution) + Toucui 100 times of solution were better,80% and 86.7%,respectively.【Conclusion】 The optimal combination of the two groups of agents is beneficial to reduce the dosage of chemical agents,decrease the cost of prevention and control,and reduce the pollution to the environment.

摘要：

【目的】 研究核桃树腐烂病的发生规律及降低病害防控过程中化学药剂的施用剂量。【方法】 于2022年4~8月在新疆和田地区布扎克乡的6个样地中,采用五点取样法,定点定株调查核桃树腐烂病的发生情况。将前期优化出的2种化学药剂:40%戊唑·咪鲜胺EW和1.6%噻霉酮PF与两种助剂:透翠树皮穿透剂和99%绿颖矿物油设置10不同处理进行施用,施药后观察病斑复发及愈合情况,计算药剂防效、助剂校正防效和病疤平均愈合宽度。【结果】 新疆和田县布扎克乡核桃树腐烂病在2022年5月和8月出现2个发病高峰期;病菌主要通过剪锯口侵入,占病斑总数的44.1%;向阳面病斑数最多;40%戊唑·咪鲜胺EW药剂减量30%+透翠100倍液和1.6%噻霉酮PF药剂减量50%+透翠100倍液处理后防效较高,分别为80%和86.7%。【结论】 筛选出的2组最优药剂组合有利于减少化学药剂的施用量,降低防治成本,减少对环境的污染。
