High efficacy of phytobiotics against euzophera of olive grove

At the start of the olive campaign, we propose in this trial the high efficacy of phytobiotics against the euzophera of olive, also known as the quince moth. Euzophera is a lepidopteran that kills young olive trees and decreases production in adult plantations. Unfortunately, its impact is important in the Spanish olive farms because it is one of the most frequent pests.

Why is it so worrisome?

Because this harmful insect (we are talking exactly about the variety Euzophera pinguis Haw) aliments from the bark and wood of the olive tree, in which it causes irreversible damage.
By significantly affecting the flow of sap, it weakens the trees little by little, until they are causing its death.

Therefore, in this case our trial is focused on verifying the high efficacy, close to 100% in the treated samples, of two different combinations of zero residue phytobiotics against olive grove euzophera. To do this, between the end of September and the beginning of October, we carried out different treatments on two samples. Both are located on the same farm (La Virtud, in Córdoba), although they are of different olive varieties. Specifically, we applied our Basictec and Frutoil phytobiotics in 125 hojiblanca variety trees and the combination of Indico and Frutoil in another 125 Arbequina variety olive trees. In both cases, there was a significant presence of Euzophera larvae and eggs before treatment on the 2-year-old trees.

THE KEYS OF THE TWO EXPERIMENTS

We can highlight the enhancer function of the Frutoil product (3L / 1000 L water), which achieves maximum efficiency when mixed with Indico and Basictec applied at minimum doses. It allows a uniform distribution; and achieves the encapsulation of the active ingredients of the phytobiotics due to its high concentration in vegetable extract from olive oil (70%).

EFFICIENCY OF BASICTEC + FRUTOIL

Our application to the trunk: 1 L Basictec + 3 L of fruit at 1000 L of water.
Once treated (at 4 days), 1 egg and 1 larva were found in the entire sample (125 trees).
Efficiency close to 100%: we managed to detach the eggs from the trunk with the oil and kill the larvae with Basictec.
The treatment does not stain the trunk or present phytotoxicity problems.

EFFECTIVENESS OF INDICO + FRUTOIL

Our application to the trunk: 2 L Indico + 3 L of Frutoil at 1000 L of water.
Once treated (at 7 days) there is no presence of eggs and in all the sampling (125 trees) a single larva is seen.
Efficiency close to 100%: we managed to detach the eggs from the trunk with the oil and kill the larvae with Indico.
The treatment does not stain the trunk or present phytotoxicity problems.

The applications in both tests were made on the trunk. In this case, it is hojiblanca olive, and Basictec-Frutoil were applied.

In the application, 2 L Indico + 3 L of Frutoil were used per tree during the 7 days at 1000 L of water.

What is Indico?

Indico acts as an anti-alimentary repellent and is fully compatible with auxiliary fauna.

What is Frutoil?

Frutoil is designed for winter treatments in stone and seed fruit trees, as an ecological alternative to mineral oils.

What is Basictec?

Basictec is an organic and biodegradable product ideal for the production of zero residue crops.

MORE INFORMATION ABOUT THE EUZOPHERA

This harmful insect of the olive tree produces the retention of the sap, as well as “wounds”, generally in the junctions of branches. They chrysalis in the gallery, near the outside, as well as the small holes can be seen in the trunk.

That is why it is so important that, when detecting the existence of this pest in the olive grove, preventive measures must be taken immediately, to avoid its spread to all the olive trees on the farm.
