Biota Tunica

We need insects to thrive, we just don’t want them destroying our plants. So instead of exterminating them, we add a protective layer to your trees. All natural, without harmful effects to insect and plant. Biota Tunica is a natural covering solution that stops bark beetles from boring holes into trees. It’s made from all natural ingredients, bound with a natural glue. Biota Tunica helps prevent infestations in periods of stress. Bark beetles attack weakened and stressed trees. Especially after planting and during periods of drought, trees are at risk. Use together with Biota Hydro Start and Biota fertilizers to keep your trees in optimal condition.

Working method

Biota Tunica encapsulates the stem of the tree, making it impossible for bark beetles to bore holes into the tree. The insect will simply look for another host. Trees treated with Biota Tunica will therefore be protected from the larvae, which feed on the phloem. This restricts the tree from transporting nutrients and can ultimately kill the tree. Depending on weather conditions, Biota Tunica will last for two months or more.

Biota Tunica can must be securely closed and stored in a cool, dark and dry place.

  • Creates a protective barrier.
  • No harmful effects on insect and plant.
  • Healthy trees during stress conditions.

Biota Tunica can be sprayed or spread on the trunk. The advice is to treat the tree from the bottom up to the primary bough, which is usually 2.5 meters high. 1 kg of product is enough for roughly 8 m2 of bark, but is highly dependent on the roughness of the bark. Depending on weather conditions, Biota Tunica will last for two months or more.

As Biota Tunica is not an insecticide, application must be done preventively. It will not work on trees with an existing infestation. Always consult with an expert and start with a test application. No guarantees can be given in the event of incorrect use.
