Cartap
    杀螟丹
Introduction: Cartap is a pesticide that was first introduced into the market in Japan in 1967. Its commercial names include Padan, Kritap, AG-Tap, Thiobel, and Vegetox. It is commonly used as a hydrochloride (C7H15N3O2S3HCl). Cartap is essentially a contact and stomach poison. It is used for the control of chewing and sucking pests and results in insect paralysis. It has been categorized as a high-effectiveness, low-toxicity, and low-residue pesticide used in rice and sugarcane fields.

ECOTOXICOLOGY
Effect on fish: Acute LC50 (96 h) for Carp is 1.6 mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is 0.01 mg/l. Effects on bees: acute (48 h) LD50 is 10 μg/bee.
ENVIRONMENTAL FATE
If released to air, an estimated vapor pressure of 4.4×10-5 mm Hg at 25℃ indicates Cartap will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase Cartap will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 5 hours. Particulate-phase Cartap will be removed from the atmosphere by wet and dry deposition. Cartap may undergo direct photolysis in the atmosphere based on a reported aqueous photolysis half-life of 34 days. If released to soil, Cartap is expected to have moderate to high mobility based upon Koc values ranging from 132-267. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 6.9×10-8 atm-cu m/mole. Cartap is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Half-lives of Cartap in various US and European soils reported from aerobic soil metabolism studies range from <1 day to 8.2 days. If released into water, Cartap is not expected to adsorb to suspended solids and sediment based upon the Koc values. Based on aerobic soil metabolism half-lives ranging from <1 day to 8.2 days, Cartap is expected to biodegrade in water. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 2 suggests the potential for bioconcentration in aquatic organisms is low.
Usage: Cartap was developed by Takeda Chemical Industries. It is a nereistoxin analogue insecticide used to control chewing and sucking pests such as aphids, spidermites, thrips, whiteflies, and jassids on soya beans, peanuts, sunflowers, maize, sugarbeet, wheat, pearl barley, fruit (including apples, pears, plums, apricots, cherries, citrus), vines, chestnuts, tea, cotton, sugarcane, etc.
Application: Biochemistry Analogue or propesticide of the natural toxin nereistoxin. Nicotinergic acetylcholine blocker, causing paralysis by blocking cholinergic transmissions in the central nervous systems of insects. Mode of action Systemic insecticide with stomach and contact action. Insects discontinue feeding, and die of starvation. Uses Cartap hydrochloride is used, at c. 0.4-1.0 kg/ha, for control of chewing and sucking insects (particularly Lepidoptera and Coleoptera), at almost all stages of development, on many crops, including rice (Chilo suppressalis, Cnaphalocrocis medinalis, Lissorhoptrus oryzophilus and rice-leaf beetle), potatoes, cabbage and other vegetables (Agromyzidae, Leptinotarsa decemlineata and Plutella xylostella); also on soya beans, peanuts, sunflowers, maize, sugar beet, wheat, pearl barley, pome fruit, stone fruit, citrus fruit, vines, chestnuts, ginger, tea, cotton, and sugar cane.
