V10 is a natural crop protection agent based on cross-protection. Developed by Valto, it is used in the cultivation of tomatoes to combat Pepino Mosaic Virus.

V10 is used to protect tomato plants against the negative effects of Pepino Mosaic Virus.

It works by means of the cross-protection mechanism: by vaccinating a plant with mild strains, the plant will exhibit fewer or no symptoms than if it is infected with an aggressive strain.

V10 is a liquid product and is diluted on a 1:10 basis with water.

To ensure effective vaccination, each plant must be treated. Rub the agent onto one leaf on every stem, just below the head and at medium height. Damaging the leaf a little will enable the V10 to be absorbed by the plant, so that it can do its job effectively and protect the plant against aggressive PepMV.

V10 is applied preventively. Plants vaccinated as soon as possible with mild strains will show fewer or no symptoms if they come into contact with an aggressive strain.

The dosage is 0.8 L V10 per ha.

In accordance with the protocol, the crop is inspected 4-5 weeks after inoculation by sampling. The results of the sample analyses indicate if V10 was successful.

The plant is protected from the symptoms of the aggressive virus about three weeks after treatment with V10, depending on the size of the plant.

Double protection offers growers more certainty than if their plants had been treated with only one strain, because there would still be a realistic chance of infection by one of the other strains.

Shelf life and stability

Store V10 in a cool place (4-10°C) in its original packaging.

V10 is stable for up to three days after receipt. See label for more information.

Once it has been prepared, V10 must be used within a few hours.

"Go for certainty: choose double protection with V10.”
