El pyrethrum or pyrethrin extract It is an insecticide obtained from the chrysanthemum flower with a broad spectrum and can be used both in the growth phase and in the flowering phase.
Pyrethrins or Pyrethrum acts on the sodium pump of neurons.
With a physicochemical process they inhibit the closure of the sodium channel in such a way that they produce a continuous transmission of the nervous impulse.
The consequences of this continued connectivity are tremors, muscle paralysis, and death.
Applications should always be made in the early morning or late afternoon.
In indoor crops, never apply with lighting on.
How is pyrethrin applied?
Diluted in water and sprayed on the leaves.
You can use it as a preventative or as an insecticide if you already have a bug hanging around your crop.
You can apply it today sprayed and spray again in a couple of days.
Growlet tip:
To prevent bugs from getting "used" to it, alternate applications with other insecticides such as Neem oil.
