摘　　要：将烯酰吗啉、福美双用有机溶剂溶解,依次加入磺酸盐类助剂和聚醚与嵌段聚醚类助剂,再加入油性溶剂与填料,搅拌均匀后,制备透明均相稳定的烯酰吗啉·福美双超低容量喷雾油剂,该药剂符合超低容量喷雾油剂的质量要求。通过室内活性试验以及田间生物活性试验,评价了烯酰吗啉·福美双超低容量喷雾油剂对荔枝霜疫霉病的防治效果。室内生物活性试验结果表明,1%烯酰吗啉·福美双超低容量喷雾油剂对荔枝霜疫霉病菌具有显著的抑制作用,在浓度为100μg/mL时,平均抑制率可达97.5%。此外,田间药效试验表明,1%烯酰吗啉·福美双超低容量喷雾油剂对荔枝霜疫霉病具有良好的防治效果,7 d防治效果为92.6%,是防治荔枝霜疫霉病的理想药剂。Dimethomorph and thiram were dissolved in organic solvents.Subsequently,sulfonate auxiliaries and polyether and block polyether additives were added to them,then the oily solvent and filler were added successively.The mixture was evenly mixed to prepare the transparent,homogeneous and stable dimethomorph·thiram ultra-low-volume(ULV)spray oil agent.The agent met the quality requirements of the ULV spray oil agent.Meanwhile,the effects of dimethomorph·thiram ULV spray oil agent on Phytophthora lychee were evaluated by laboratory bioactivity tests and field efficacy trials.The results of laboratory bioactivity tests showed that 1%dimethomorph·thiram ULV spray oil agent had a significant inhibition rate against Phytophthora lychee,and the inhibition rate was 97.5%when the concentration was 100μg/mL.The field efficacy trials showed that dimethomorph·thiram ULV spray oil agent had a good control effect on Phytophthora lychee,which reached 92.6%in 7 days.It was an ideal agent to control Phytophthora lychee.
