Pymetrozine 吡蚜酮

Introduction: Pymetrozine is a novel insecticide for the control of aphids and other sucking pests in cotton and represents a new class of control agents. The compound interferes in the feeding behaviour of insects and controls insects resistant to standard chemistry. Because of its unique mode of action, pymetrozine does not harm beneficial insects and is very useful in Integrated Pest Management (IPM) programs. The compound exhibits low acute toxicity to mammals and has favourable environmental properties. Use rates are 100-300 g a.i./ha. Full development is underway around the world.

ENVIRONMENTAL FATE

Animals Quickly and efficiently eliminated (mainly via excreta) and extensively metabolised in all species tested (rats, farm animals), without accumulation in most major animal food products. The metabolic pathways are similar for all species. Pymetrozine is the relevant residue for assessing the consumer exposure to treated animal food products. Plants The basic degradation steps are similar in all investigated crops; pymetrozine is the only relevant compound for residue definition. Soil/Environment In soils, very rapidly and strongly adsorbed, with low mobility and low leaching potential. Soil DT50 2-69 d, DT90 55-288 d. Rapidly degraded in slightly acidic or sunlight-exposed surface water; DT50 in surface water (typical value) 7 d. Slightly volatile. Efficiently removed by direct photolysis and photochemically induced oxidation.    

Usage: Pymetrozine was introduced by Ciba-Geigy Corporation. It is a novel azomethine insecticide suitable for use in integrated crop management to control aphids and other plant sucking pests.  

Application: Biochemistry Novel, unidentified biochemistry. Mode of action Insecticide selective against Homoptera, causing them to stop feeding. Uses Control of aphids and whitefly in vegetables, potatoes, ornamentals, cotton, deciduous and citrus fruit, tobacco, hops; both juvenile and adult stages are susceptible. Also control of planthoppers in rice. Application rates vary from 150 g/ha on potatoes to 200-300 g/ha on ornamentals, tobacco and cotton; 10-30 g/hl on vegetables, fruit and hops.
