摘要
针对秦巴山区烟田移栽期病虫害频繁发生的问题,本研究对不同生物农药和杀虫剂组合的烟草根部病虫害防治效果进行了评价.在烤烟井窖式移栽作业过程中,通过提前施用不同组合的生物农药和杀虫剂,在移栽期统计病虫害发生情况.结果发现,不提前使用药剂的防治效果最差;施用解淀粉芽孢杆菌和“润土润根”对烟草黑胫病的防治效果最好,相对防治效果为92.62%~93.10%;施用解淀粉芽孢杆菌和“润土润根”对烟草根黑腐的防治效果最好,相对防治效果为86.96%~87.10%;施用噻虫·高氯氟对小地老虎的防治效果最好,相对防治效果为78.57%~85.71%.因此,针对烤烟移栽期主要根茎类病虫害的最佳防治药剂组合为噻虫·高氯氟+解淀粉芽孢杆菌或噻虫·高氯氟+“润土润根”.本研究为秦巴山区烟草移栽期主要根部病虫害的防治提供了有效药剂组合的施用参考.
In view of the frequent occurrence of diseases and pests during the period of tobacco transplanting in Qinba mountainous area,this study evaluated the effect of tobacco root diseases and pests control with different biopesticides and insecticides combinations.In the process of transplanting flue-cured tobacco with well-cellar method,the occurrence of diseases and pests was investigated during the transplanting by applying different combinations of biological pesticides and insecticides in advance.It was found that the control effect of not using agents in advance was the worst.The application of Bacillusamyllyticus and‘Runturungen’had the best control effect on tobacco black shank and tobacco black root rot with relative control effect of 92.62%~93.10%,and 86.96%~87.10%,respectively.The application of thiacloprid-chlorofluoride had the best control effect on Agrotisipsilon,and the relative control effect was 78.57%~85.71%.Therefore,the best combinations for control of main root pests and diseases of tobacco during the transplanting period are thiacloprid-chlorofluoride+Bacillusamylolytica,and thiacloprid-chlorofluoride+‘Runturungen’.In conclusion,this study provides an effective reference for the control of tobacco pests and diseases during the transplanting period in Qinba mountainous area.
