Study on the Controlling Bactericides and Their Applying Time of Pseudomonas syingae pv. tabaci
摘要
Abstract
In order to control Pseudomonas syringae pv.tabaci more effectively,a field plot experiment was conducted in Yibin to study the effects of four bactericides and three application periods on the occurrence of P.syringe pv.tabaci.The results showed that the bactericides and application period influenced disease index,yield and production value significant-ly.The control effect of 4%Kasugamycin was the best and it reached the lowest disease index at three application period, followed by 3%Benziothiazolinone and 20%Thiediazole copper,the effect of 50%Chloroisobromine cyanuric acid was the lowest.It was best to start the bactericides application at the end of the fast growing stage,the mean value was the highest (41 863.95 yuan/hm2),followed by the mature stage of lower leaf.The combined effects of bactericides and application periods on tobacco production value were periods >actericides >interaction of periods and bactericides.Comprehensive consideration of the disease index and output value,the optimal pattern of bactericides and periods to control Pseudomonas syringae pv.tabaci was that the 4%Kasugamycin(800 times)and applied at the end of the fast growing stage in Yibin to-bacco area.关键词
