Deltamethrin 52918-63-5 98% TC, 5% WP, 25 g/l EC



Introduction: Deltamethrin is a synthetic insecticide based structurally on natural pyrethrins, which rapidly paralyze the insect nervous system giving a quick knockdown effect. Deltamethrin has a rapidly disabling effect on feeding insects and for this reason there is hope that it may be useful to control the vectors of "non-persistent" viruses (viruses that can be passed on by the vector within a few minutes of starting to feed on the plant). Deltamethrin's mode of action is thought to be mainly central in action, or at least originate in higher nerve centers of the brain. Death of insects seems to be due to irreversible damage to the nervous system occurring when poisoning lasts more than a few hours. Deltamethrin poisoning occurs through cuticular penetration or oral uptake. The susceptibility of insects is dependent on a variety of factors and can vary, as with many insecticides, according to the environmental conditions. Flies are most susceptible to pyrethroid poisoning shortly before dawn. The LD50 drops by the factor of 2 as compared to full daylight activity.

WHO Classification: II (Moderately hazardous)

EC Risk Classification: T - Toxic: R23/25; N - Dangerous for the environment: R50, R53.

US EPA Classification (formulation): II (Warning - Moderately toxic)


Effect on birds: Acute oral LD50 for Bobwhite quail is >2250 mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is 0.00026 mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is 0.00056 mg/l. Effects on algae: Acute EC50 (72 h) is 9.1 mg/l. Effects on bees: Contact acute (48 h) LD50 is 0.0015 μg/bee, Oral acute (48 h) LD50 is 0.079 μg/bee. Effects on earthworms: Acute 14 day LC50 is >1290 mg/kg.


Breakdown of Chemical in Soil and Groundwater: In soil, degradation occurs within 1-2 weeks. Breakdown of Chemical in Surface Water: Deltamethrin in pond water was rapidly adsorbed, mostly by sediment, in addition to uptake by plants and evaporation into the air. Breakdown of Chemical in Vegetation: About 10 days after use, there are no deltamethrin residues observed on plants. There is no known phytotoxicity to crops.   

Usage: Deltamethrin was developed by Roussel Uclaf. It is a fast-acting insecticide used to control a wide range of pests such as cockroaches, spiders, ants, fleas, silverfish, bed bugs, bird mites, mosquitoes, house flies, and beetles, on commercial, industrial and public buildings, public health situations, stored produce.

Application: Biochemistry Like all pyrethroids, prevents the sodium channels from functioning, so that no transmission of nerve impulses can take place. Mode of action Non-systemic insecticide with contact and stomach action. Fast-acting. Uses A potent insecticide, effective by contact and ingestion against a wide range of pests. Crop protection uses include: Coleoptera (2.5-7.5 g/ha), Heteroptera (5.0-7.5 g/ha), Homoptera (6.2-12.5 g/ha), Lepidoptera (5.0-21 g/ha) and Thysanoptera (5-10 g/ha) in cereals, citrus, cotton, grapes, maize, oilseed rape, soya beans, top fruit and vegetables. It controls Acrididae (5.0-12.5 g/ha), and is recommended against locusts. Soil surface sprays (2.5-5.0 g/ha) control Noctuidae. It is used against indoor crawling and flying insects (12.5 mg/m2) and pests of stored grain (0.25-0.5 g/t) and timber (Blattodea, Culicidae, Muscidae). Dip or spray (12.5-75 mg/l), and pour-on (0.75 mg/kg b.w.) applications give good control of Muscidae, Tabanidae, Ixodidae and other Acari on cattle, sheep and pigs, etc.
