[Objective] This paper was to improve the current status that the fungicide carbendazim as the single agent was largely applied in the control against wheat scab. [ Method] Five kinds of fungicides on sales and new agents against wheat scab were selected for field trials. [ Result] 25% JS399 - 19 SC, 30% te- buconazoh · thiram WP, 75% trifloxystrobin · tebuconasole WDG and 10% ZJ0712 JG could effectively control wheat scab, and the control effects of one time or two times application were better than control agent carbendasim; the control efficacy of two times application was improved in different degrees against one time ap- vlication. [ Conclusion] The naner vrevided basis for the control atminst wheat scab. 展开更多

CONSPECTUS:The microfluidic biochemical/immunoassay systems typically consist of microfluidic chips,fluid driving devices,and detection components.The core of the system is the microfluidic chips based on microfluidic technology,which are typically constructed with nonresponsive materials such as silicon,glass,and rigid plastics,thus requiring complex external air/liquid pumps to manipulate the samples.The external equipment renders the microfluidic systems cumbersome and increases the risk of biosample contamination. 展开更多
