　　Uses

　　Nereis toxin pesticides, with contact kill, stomach toxicity, a certain absorption of conduction, and have ovicidal properties. This product has slow toxic effect on pests, short residual period, and good control effect on lepidoptera and coleoptera pests. It is mainly used for rice pests. The general dosage is 5.3~7.5g active ingredient/100m2, and the control effect is more than 90%. For example, to control rice stem borer and rice stem borer, 50% soluble powder 10.5~12g/100m2 is used, and water is poured or sprayed. Control of rice leaf roller, rice bract insects, but also available the same amount of chemicals poured burn. Can be mixed with fast-acting pesticides. Use caution in silkworm areas.

　　Toxicity and ecology

　　Toxicological data of Thiocyclam:

　　Acute oral LD50 in male rats was 310mg/kg, and 273mg/kg in male mice. Acute percutaneous D501000mg/kg in male rats, acute inhalation of LD50>4.5mg/L in male rats. It has a mild irritating effect on rabbit skin and eyes. The non-acting dose of the 90d feeding test for rats was 100mg/kg, and for dogs it was 75mg/kg. It has no teratogenic, carcinogenic, or mutagenic effects. Carp LC50 is 1.03mg/L (96h). The oral LD50 of bees is 11.9 µg/pc. Bees are low in toxicity, toxic to silkworms, low in toxicity to birds, and safe for natural enemies such as spiders.
