Ostroka Black Rain is an organic ecological insecticide and acaricide used for the control of many species that can affect our cannabis garden, now available at Alchimiaweb.com.

Ostroka Black Rain, broad-spectrum organic insecticide

This insecticide product is composed of SO3 (25%), citric terpenes, castor oil and surfactants which keep longer the active principles thus increasing its effectiveness.

This mixture acts against insects, removing all kinds from our plants and preventing any cannabis pests infestation without leaving any residue in the plant tissues.

Ostroka Black Rain, eliminates red spider, whitefly and thrips

It is effective against spider mite, whitefly, thrips, cochineal and aphids among other species. It can be used as preventive or when the pest has infested our cannabis plants.

Dilute the product in water, 3ml per litre (adult plants) or 2ml per litre (young plants). Spray well the leaves on both sides, applying the insecticide 3 times a week or up to every two days if the infestation in our cannabis varieties has widespread.

In order to maximize the insecticide effect, we will apply it at the end of the day or at night, to avoid product degradation caused by direct sunlight.
