标题:一种氟啶脲的合成方法及其用于制备杀虫剂 的用途
摘要:本发明属于农药制剂技术领域,具体涉及一种氟啶脲的合成方法,并进一步公开其用于制备杀虫剂的用途.本发明所述合成氟啶脲的方法,以现有技术中常规合成线路为基础,以2,3‑二氯‑5‑三氟甲基吡啶,2,6‑二氯‑4‑氨基苯酚,以及2,6‑二氟苯甲酰异氰酸酯为合成原料,并以n,N‑二甲基乙酰胺为反应溶剂,在zsm分子筛催化剂的作用下,不仅可以实现氟啶脲的合成,同时可以仅在同一反应溶剂下实现反应进行,避免了现有技术中两步法合成氟啶脲需要逐步回收溶剂导致工艺复杂的问题,同时产物的合成产率较现有技术工艺进一步提高,且产物含量较高.

标题:Use of molt-accelerating compounds, ecdysteroids, analogs thereof, and chitin synthesis inhibitors for controlling termites

摘要:The subject invention relates in part to the oral administration of ecdysteroids for controlling subterranean termites. Preferred ecdysteroids for use according to the subject invention are ecdysone, certain ecdysone analogs, and 20-hydroxyecdysone, for example. In some preferred embodiments, one or more of these compounds is used in a termite bait in combination with one or more chitin synthesis inhibitors. Thus, the subject invention also relates in part to controlling termites by the use of a chitin synthesis inhibitor (CSI), such as hexaflumuron and/or noviflumuron, together with an ecdysteroid (and analogs thereof) or molt-accelerating compound (MAC), such as halofenozide. The subject invention also relates to mixtures comprising these two active ingredients. The MAC/ecdysteroid analog induces a preliminary molting event in termite workers (they could not complete the molting), which then allows the CSI to further disrupt the molt and cause mortality. The combination of these active ingredients, causing accelerated molting together with inhibition of chitin synthesis, is surprisingly shown herein to enhance activity against termites, as compared to either group of compounds alone.
