通州区刺萼龙葵的化学防除试验研究

The Chemcial Control of Solanum rostratum in Tongzhou,Beijing

为了明确各类除草剂防除刺萼龙葵的效果,为其应急防控提供科学依据,于2011年在北京通州区刺萼龙葵发生地进行了田间药效评价研究.结果表明,茎叶处理剂三氯吡氧乙酸48％乳油、氨氯吡啶酸24％水剂和氯氟吡氧乙酸20％乳油能够有效防治刺萼龙葵,三氯吡氧乙酸和氨氯吡啶酸所有试验剂量对刺萼龙葵的鲜重防效均达到100.0％,氯氟吡氧乙酸设计剂量下防效为86.20％～95.58％,根据药剂的不同特性,可制定不同入侵地的刺萼龙葵的防控策略.

In order to provide scientific basis for controlling buffalobur,field herbicide trial was conducted in 2011 in Tongzhou,Beijing.The results showed that triclopyr 48％ EC and picloram 24％ AS gave excellent control efficacy of buffalobur （100.0％）,fluroxypyr 20％ EC could control buffalobur effectively either,which control efficacy were 86.20％～95.58％.According to the different characteristics of herbicides,chemcial control strategies of buffalobur could be made for different invasion areas.
