摘 要:以呋喃威與多殺菌素為研究對象,研發(fā)出一種6%呋喃威·多殺菌素微囊懸浮劑。采用界面聚合法,以聚脲異氰酸酯為壁材制備6%呋喃威·多殺菌素微囊懸浮劑。測定了呋喃威與多殺菌素微囊的形貌、粒徑和包封率,并評價(jià)了呋喃威與多殺菌素微囊懸浮劑的室內緩釋性能。結果表明:微囊粒徑約為2~5 μm,分布均勻,包封率為95.2%。呋喃威與多殺菌素在50 d時(shí)的累積釋放率分別為78.3%和73.1%。具有持效期長(cháng)、對環(huán)境適應性強、農藥利用率高等優(yōu)點(diǎn),同時(shí)對人、畜和害蟲(chóng)的天敵安全性高,具有推廣價(jià)值。 |

Abstract:In this paper, a microencapsulated suspension of 6% benfuracarb-spinosad was developed with benfuracarb and spinosad as the research objects.The 6% benfuracarb-spinosad fungicidal microcapsules suspension was prepared by interfacial polymerization using PAPI as the wall material.The morphology and particle size of mother liquor of benfuracarb and spinosad microcapsules and the indoor sustained release performance of their microcapsule suspensions were tested. The results showed that: themicrocapsules particle size wasabout 2~5 μm; the encapsulation rates of benfuracarb was 95.2%; The release rates of benfuracarb and spinosad were 78.3% and 73.1% after 50 days respectively.It has the advantages of long duration, friendly environment, strong adaptability to the environment, high utilization rate of pesticides, high safety to natural enemies of human, livestock and pests, and has the value of popularization. |
