Project Description

Vegesol eReS

Vegesol eReS can be used not only in the beginning of spring, but during the entire growing season, though in somewhat smaller doses, as its oil content is sufficient only for the patented film formation but does not cause toxicity.

The pests that appear in the growing season, such as harmful fungi, bacteria, and of course animals, are present in orchards during the wintertime as well. In the interest of avoiding any subsequent damages they would cause, the number of these pests should be decreased to a minimum in the early spring. If this is successful, you will be able to start the growing season with a clean slate and will have a better chance of preventing the spread of diseases and pests.

Although this approach is true in general, it is not effective against all pathogens and pests, as a late-dormancy application is able to reduce the numbers of and kill only those pests that overwinter on the branches and shoots of trees and shrubs. Late-dormancy spraying is ineffective against the pests that spend the winter in the soil or in fallen leaves.

Timing is a very important aspect in ensuring the good efficacy of the late-dormancy application. Spraying should generally take place after the winter frosts but before the buds burst. The best results can be achieved right at the start of vegetative growth, as that is when pests become the most active. However, as certain pathogenic fungi (e.g. apple powdery mildew) overwinter hidden between the bud scales, the treatment should be applied only when the buds have burst and the spray can permeate their interior.

Fungicidal late-dormancy sprays have to contain a number of active ingredients toensure their effectiveness against all of the large number of pests. The result of the work of the developers at BVN, Vegesol eReS provides a combination of copper hydroxide and sulphur along with a plant oil content that helps elevate the adhesion of these two fungicidal active ingredients to exceptional levels. Copper and sulphur provide the product with a wide spectrum against the various types of pathogenic fungi and, thanks to its added excipients, the oily formula forms a film on the surface that is slow to degrade, thus ensuring that the active ingredients can exert their lasting biological effects. This is the patented technology that makes BVN’s products unique. It also explains why Vegesol eReS provides excellent biological efficacy against Peronosporales types of moulds while using less copper; and the effect also applies to sulphur as an active ingredient.
