目的 观察植物素９５０１ 杀钉螺的效果和毒性。方法 实验室杀成螺、幼螺、螺卵试验采用浸杀法；现场草洲采用喷洒法；垸内沟渠用沿边铲草浸杀法；毒性试验用胃灌法和皮肤、粘膜刺激法。结果 ９５０１ ５ｍ ｇ／ Ｌ和１０ｍ ｇ／ Ｌ实验室浸杀成螺、幼螺、螺卵的死亡率均达 １０００％ ；现场浸杀成螺死亡率分别为 ９８０％ 和 １０００％ ；１０ｍ ｇ／ Ｌ垸内沟渠铲草浸杀活螺平均密度下降率为９４６％ ；喷洒４０ｇ／ｍ ２ 死亡率为６００％ ；小白鼠口服急性毒性 Ｌ Ｄ５０大于５ ０００ｍ ｇ／ｋｇ；对家兔眼结膜有轻微刺激，对皮肤刺激不明显；５ｍ ｇ／ Ｌ使鱼全部死亡，４ｍ ｇ／ Ｌ对鱼安全。结论 ９５０１ 浸杀钉螺、幼螺、螺卵效果好，喷洒杀螺作用差；对人、畜毒性低，对鱼有一定毒性；与油茶皂素比较，具有剂型稳定，不回潮结块，易保管等优点。
Objective To observe the effect and toxicity of Phytocins 9501 to kill snails. Methods Lab kill spire, snail, spiro egg test using immersion method; field CaoZhou sparging method; embankment ditch with shovel grass dip method; toxicity test with gastric irrigation and skin, mucosal stimulation method. Results The mortalities of snail and baby snail were all 1000% at 9501 5m g / L and 10m g / L, respectively. The mortality rate of snail oncomelania were 980% and 1000 %; 10m g / L embankment trenches shoveling dip snail average density reduction rate was 94 6%; spray 40g / m 2 mortality was 60 0%; mice acute oral toxicity L D50 greater than 5 000m g / kg; there is a slight irritation to the conjunctiva in rabbits and no obvious irritation to the skin; 5m g / L causes all the fish to die and 4m g / L is safe for the fish. Conclusion 9501 dip snail, snail, spiro egg effect is good, spraying spiro effect is poor; to humans, animal toxicity is low, a certain toxicity to the fish; compared with Camellia saponin, with a stable dosage form, no resurgence lumps, easy to custody Etc.
