Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminate long-stored food and it causes different toxic effects, like nephrotoxic, hepatotoxic and cytotoxic effects. Citrinin is mainly found in stored grains, but sometimes also in fruits and other plant products.

生产方法
1.是日本三共株式会社1974年从土壤中分离的放线菌吸水链霉菌金色亚种Streptomyces hygroscopicus var.aureolacrimosus的代谢产物。其产品由产生菌经培养、发酵、加工而成。 1.微生物源杀虫杀螨剂,作用方式与阿维菌素一样,但桔霉素杀虫谱较窄。主要用于果树 ( 如柑橘等)防治各种害螨,对棉叶螨和橘全爪螨高效,但对卵的活性较差。推荐防治螨类使用剂量为5.6～28g/hm2,制剂中加入矿物油能增加渗透性,提高对螨卵的杀卵活性。
