Function

Insecticide and acaricide effective against phytophagous mites

(Tetranychidae, Tarsonemidae), Aleyrodidae, Aphididae and

Jassidae on cotton, various field and fruit crops, ornamentals and

vegetables. Also controls some leaf-feeding pests

in cole crops (Plutella xylostella), soya beans (Anticarsia gemmatalis)

and cotton (Alabama argillacea). Is safe on adults of all beneficial

groups (Anthorcoridae, Coccinellidae, Miridae) and on adults and

immature stages of predatory mites (Amblyseius andersoni,

Typhlodromus pyri), spiders (Erigoridae, Lycosidae),

Chrysopa carnea. Non-selective to immature

stages of Heteroptera (Anthocoridae, Miridae).

Compatible with the biological control of Aleyrodidae and mites in glasshouses.
