Definitions

  • the present invention relates to a method for preventing the onset of plant infections, so avoiding the beginning and the stabilisation of diseases, which consists in the application of widely active non-phytotoxic fungicide compositions to the cultivations , which comprise at least a saturated or unsaturated fatty acid, having a carbon atom number from 14 to 22, or at least a derivative thereof, i.e. salt and others, or a mixture thereof or, even, one and/or the other as such or mixed with a vegetal oil; the invention also relates to these very compositions when employed in the prevention of the cultivation infestations.
  • the object of the present invention is a method for the plant infection prevention which comprises the application to the interesting cultivations of a composition, on turn the second object of the present invention, containing as the active principle, at least a saturated or unsaturated fatty acid having a carbon atom number in the C ⁇ 4 ⁇ C 2 narrow range, or at least a derivative thereof, i.e. salts or others, or mixtures of at least a fatty acid and at least a derivative of at least of the abovesaid fatty acids, the same or different, the acid and/or the derivative being present as such or, again, mixed with at least a vegetal oil.
  • the fatty acids employable according to the present invention may be non-substituted, substituted, saturated, unsaturated: particular examples are oleic acid and linoleic acid.
  • Fatty acid derivatives may be their salts, particularly with alkaline metals, sodium and potassium above all, or with amines such as isopropylamine, or their esters.
  • vegetal oil As far as the vegetal oil is concerned, it can be selected among many compounds, for example rape oil, soja oil, grape seed oil, and so on.
  • composition according to the present invention comprises also the possible addition of control chemical agents, more generally biological agents, which can be suitably selected by those skilled in the art in view of the aims to be achieved.
  • control chemical agents that can be added to the prevention composition according to the present invention are the fungicides inhibiting the ergosterol biosynthesis such as, again by way of examples, fenarimol, propiconazole, proclonaz and tebuconazole.
  • compositions to be used according to the invention purposes can be prepared according to procedures that are well known to those skilled in the art: therefore, use will be made of suitable solvents and emulsifying agents, as well as of the known wetting and surface active agents such as the ones commonly used in the field of the agricultural crops.
  • the method, as well as the relevant composition, according to the present invention can be employed to prevent the onset of infestations caused by several fungal and bacterial agents.
  • composition according to the present invention can occur on all parts of the plant, and the experience of the man skilled in the art will be the guidance to decide where such an application is to be carried out, whether on seeds, on bulbs, on roots, on leaves, etc.
  • Plants that can be protected are all cultivable ones; for istance, mention may be made of vines, of the arboreous plants as pears, apples, of the cucurbitaceous, the solonaceous, the floral plants, of the cereals as grain, barley, of the chords, of the vegetables as lettuce, onion, and the like.
  • composition to be used in the method according to the present invention is not limited by the concentration of the active component (i.e. fatty acid, and others), which can be selected by those skilled in the art on the ground of true application needs: however, a particular interested is correlated to concentrations, expressed as active component total weight with respect to the composition total weight, in the range from 10% to 80%.
  • carboxylic acids and its derivative may be in a ratio ranging from 1/10 to 10/1; again correlated to carboxylic acid or the derivative thereof, if employed as such, the vegetal oil is present in a ratio between 1/10 and 10/1.
