(Not known by any other names)

SUMMARY

Cartap is a largely obsolete insecticide. It is highly soluble in water, has a low volatility and tends not to persist in soil systems. There are data gaps regarding its human health effects but is known to be moderately toxic. There are also data gaps regarding its ecotoxicity but is highly toxic to aquatic vertebrates and moderately toxic to fish.

Data alerts

The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.

GENERAL INFORMATION

Description

A nereistoxin analogue insecticide used to control chewing and sucking pests

Example pests controlled

Aphids; Spidermites; Thrips; Whiteflies; Jassids

Example applications

Soya beans; Peanuts; Sunflowers; Maize; Sugarbeet; Wheat; Pearl barley; Fruit including apples, pears, plums, apricots, cherries, citrus; Vines; Chestnuts; Tea; Cotton; Sugarcane

Efficacy & activity

Cartap was reasonably effective at controlling chewing and sucking insect pests but more effective and less toxic pesticides may now be available.
