Natural Pesticide Pyrethrum Extract 50% 70% Pyrethrin

Product Description

 Application

Non-systemic insecticide with contact action. Causes rapid knockdown (caused mainly by Pyrethrins II), with death occurring later (associated with Pyrethrins I). Has some acaricidal activity. 

Control of a wide range of insects and mites in public health, stored products, animal houses, and on domestic and farm animals. Control of chewing and sucking insects and spider mites on fruit, vegetables, field crops, ornamentals, glasshouse crops, and house plants. Also used as personal insect repellents and for human head lice control. Normally combined with synergists, e.g. piperonyl butoxide, which slows down detoxification by the insects.
