超低容量(ULV)喷雾是近十余年来发展起来的一项高功效杀虫的新技术,近几年来国内在灭蚊蝇方面用于地面与空中。至于手持超低容量喷雾器除了MG—I型主要用于农业灭虫外,目前国内适用于滞留喷洒和小面积杀虫的小型ULV喷雾器械甚少,而肇—78型手持ULV喷雾器尚能弥补这一不足,特对其室内喷洒性能进行了实验研究。
Ultra-low-volume (ULV) spray is a new and highly effective insecticidal technology developed in the last ten years. In recent years, it has been applied to ground and air in the field of mosquito-killing in China. As for the hand-held ultra-low volume sprayers, except MG-I type is mainly used for agricultural pest control, at present, there are few small ULV spray devices suitable for detention spraying and small-area insecticide in the country, while Zhao -78 hand-held ULV sprayers can still make up for this An inadequate, especially for its indoor spray performance of the experimental study.
