沙蚕毒系农药是有机氮类农药的一个分支,它是仿照天然沙蚕毒素的化学结构,人工合成的一类仿生性杀虫新农药。目前已使用的品种有巴丹(又称杀螟丹、沙蚕丹或沙蚕胺)、杀虫双和杀虫环(又称易卫杀、杂虫环、虫噻烷和甲硫环)。杀虫双原系制造巴丹的中间体,由我国首先发现其杀虫活性,并首先生产,现已在我国农村中广泛使用。本类农药纯品多为白色结晶固体,易吸潮,在水中溶解度较大,故可制成水剂(市售杀虫双为25%水剂呈棕红色)
Nereis vicina var. Pestis is a branch of organic nitrogen pesticides, which is modeled on the chemical structure of natural Nereis toxin, a kind of synthetic biomimetic insecticide new pesticides. At present, the varieties that have been used are Bataan (also known as Cartap, salbutamol or selembiline), insecticidal double and insecticidal ring (also known as easy to kill, coccidiosis, worm and sulfur methyl ring) . Insecticidal double original system for the manufacture of Bataan intermediates, first discovered by our insecticidal activity, and the first production, is now widely used in rural China. Pure pesticides mostly white crystalline solid, easy to absorb moisture, solubility in water, it can be made of water (commercially available insecticide double as 25% red brown)
