    [0002] Procedure to treat the vines, applied composition and method of obtaining it
    [0004] The present invention relates to a process for treating grapevines, as well as the biocidal vine coating composition used in the process and the method for obtaining the same. The coating can be used on: grafts, rootstocks, roots and vine bases. The coating comprises in its composition a biocidal compound, to prevent or treat grapevines.
    [0006] Background of the invention
    [0008] There is a great problem associated with the diseases of the vines, since the vines leave the nurseries in many cases contaminated. One of the stages where many of the infections occur is in the graft work.
    [0010] At present, various products and techniques are known that are applied to grafts, rootstocks, bases and roots, to minimize the effects that viruses and bacteria have on the grafting processes that are carried out in nurseries.
    [0012] Therefore, it would be very positive to find a preventive method and control strategies for vines that are contaminated or that can be contaminated with viruses, bacteria, fungi, and others. The plants from the nurseries come with the inoculum that causes future diseases. It would be very appropriate to apply a product that prevents diseases both in the nursery before planting or grafting, and outside it, when pruning.
    [0014] In the specific case of the vine, the interest in the control of these diseases has come because a noticeable increase in the mortality of young vine plants from the nursery has been detected, in the 1 to 3 years after their planting in the countryside.
    [0016] In addition, in the case of wood diseases, the progressive suspension of the use of sodium arsenite, which was the only control measure traditionally used in wood diseases in grapevines such as tinder, has brought about a progressive increase in the incidence, spread and losses due to these diseases.
    [0017] Document ES2543363 describes a product for the control of phytopathogenic fungi that cause diseases of grapevine wood and the procedure for its application in grapevine grafts. This invention is based on the use of biological control agents (BCAs) of 3 selected strains of actinobacteria.
    [0019] Patent with publication number ES2389343 refers to the use alone or in combination of three natural compounds / extracts that have antifungal properties, these compounds are selected from chitosan, hydroalcoholic extract of garlic and vanilla.
    [0021] The inventors have developed a composition that facilitates the application of a biocidal coating on plants in the nursery or outside, and that prevents and treats the development of possible diseases.
    [0023] Description of the invention
    [0025] The present invention has developed a biocidal composition of a coating for grapevines that, among other advantages, highlights the easy application to them. Furthermore, the biocide present in the composition is mixed with a wax that facilitates its application and allows the action of the biocide to be continuous by contact.
    [0027] The biocidal composition comprises a wax and a biocidal compound selected from: metal, salts thereof, a metal oxide or combinations thereof where the metal is selected from: Ag, Cu, Ni, Co, Fe, Zn, Ti, Ca ; supported on a clay or on zeolite.
    [0029] As we have said, the present biocidal coating composition is useful for treating grapevines. To be able to apply it to the vine, it is necessary to melt the composition comprising the wax and the biocide, apply this composition in the liquid state and then let it cool so that it hardens and creates a protective film on the plant.

    [0123] Two groups of vines were compared, some treated with the coating of the invention and others untreated. Each plant was grown independently and arranged in two lines treated and untreated.
    [0125] The coating from Example 1 melted around 80 ° C and was applied to the graft callus immediately placed in a water bath to solidify.
    [0127] The untreated plants presented 90% infection by grapevine wood fungi. This infection comes from the root (20%) and / or rootstock base (10%) and / or the graft (80%).
