摘　　要：[目的]调查30%炔螨特微囊悬浮剂防治沃柑红蜘蛛的药害情况。[方法]分为预实验和正式实验两个阶段进行红蜘蛛防治的药效试验,预实验分为4个实验组,正式实验分为15个实验组。试验设置在沃柑夏梢生长和幼果生长期的5~6月,通过单独采用30%炔螨特微囊悬浮剂的不同浓度进行试验以及与其他不同的螺螨酯、寡糖·吡唑酯、高氯·啶虫脒等药剂进行混合使用进行试验,并通过观察幼果、嫩梢、未老熟叶片、老熟叶片的药害情况。[结果]预实验和正式实验的结果都表明在夏季气温不是很高的条件下,30%炔螨特微囊悬浮剂单独喷施或与其他药剂混配,对沃柑老叶、嫩梢、嫩叶和幼果是安全的。[结论]气温不是很高的条件下,30%炔螨特微囊悬浮剂可以安全防治沃柑红蜘蛛。[Objective] To investigate the effects of 30% propargite microcapsule suspension agent for red spider control in Orah mandarin.[Method] The efficacy test of red spider control was carried out in two stages:pre-experiment and formal experiment.The pre-experiment was divided into 4 experimental groups,and the formal experiment was divided into 15 experimental groups.The experiment was set in May and June during the summer shoot growth and young fruit growth period of Orah mandarin.The experiment was carried out by spraying different concentrations of 30% propargite microcapsule suspension agent alone or mixed with different agents such as spirodiclofen and oligosaccharide.pyrazole ester,chloropyridine,etc.,and conducted contrastive analysis of efficacy test by observing the young fruit,tender shoot,immature ripe leaves,old ripe leaves.[Result] The results of pre-experiment and formal experiment showed that 30% propargite microcapsule suspension agent sprayed alone or mixed with other agents was safe for the old leaves,tender shoots,tender leaves and young fruits of walter mandarin under the condition of low temperature in summer.[Conclusion] Under the condition of temperature is not very high,30% propargite microcapsule suspension agent can safely control the red spider.
