Definitions

• the proposed method has the advantage of not being significantly phytotoxic. It therefore does not damage the treated plants.
• compositions comprising a mixture (i) of at least two carboxylic acid esters comprising at least 14 carbon atoms, linear or branched, saturated or not, optionally comprising at least PCTJFRO 3 / ⁇ i * 6 B
• composition relates to the use of this composition during which the composition is mixed with a phytosanitary formulation, before or after dilution of said formulation in an aqueous phase.
• the alcohol from which the ester is prepared can be more especially chosen from methanol, ethanol, propanol, ispropanol, butanol, isobutanol, octanol, 2 ethyl hexanol, glycerol, glycol, propylene glycol, ethylene glycol, polyethylene glycol, polypropylene glycol, neopentylglycol, pentaerythritol, neopentylglycol hydroxy pivalate, dipentaerythritol, trimethylolpropane, di-trimethylolpropane, glucose, fructose, arabinose, sorbitol and its optical enantiomers, sucrose, mannitol, xylitol, mesoerythritol, alone or as a mixture.
• the ester used as a constituent element of the composition can also be chosen from products resulting from the transformation of triglycerides of animal or vegetable origin.
• Triglycerides of animal or vegetable origin are generally called animal or vegetable oils, and consist of a triester of three fatty acid chains (carboxylic acid) and a triol (glycerol).
• the term “ester” does not cover triesters. The ester used therefore does not cover oils of animal or vegetable origin.
• oils of animal origin there may be mentioned, among others, sperm whale oil, dolphin oil, whale oil, seal oil, sardine oil, herring, shark oil, cod liver oil; beef foot oil, fat from beef, pork, horse, sheep (tallow).
• the triglycerides can comprise fatty chains of acids comprising less than 14 carbon atoms.
• the proportion in this type of fatty chains is less than 50% by weight of the fatty chains which enter into the composition of the triglycerides concerned.
• composition further comprises at least one nonionic surfactant.
• the optionally alkoxylated fatty alcohols generally contain from 6 to 22 carbon atoms, the alkoxylated units being excluded from these numbers.
• the optionally alkoxylated sorbitan esters are cyclized fatty acid sorbitol esters comprising from 10 to 20 carbon atoms such as lauric acid, stearic acid or oleic acid.
• the surfactants are chosen from polyalkoxylated nonionic surfactants.
• the phytosanitary active ingredient is not soluble or miscible in the composition, it may be advantageous to incorporate into the composition, at least one compatibilizing additive chosen from pH correcting agents and / or anionic surfactants.
• anionic surfactants the following surfactants may be mentioned, alone or in mixtures:
• the plants to be treated according to the process of the invention are more especially chosen from the families of liliaceae (lilies, tulips, hyacinths, etc.), solanaceae (potatoes, tomatoes, etc.) cucurbits (zucchini, peppers, eggplant, etc.) or any other vegetable crop.
• composition according to the invention can comprise at least one liquid or solid phytosanitary active material, soluble or not in the composition.
• This phytosanitary active ingredient can be chosen from pesticides, and more particularly insecticides, but also from nutrients promoting the growth and development of plants.
• the composition can also comprise the conventional additives of phytosanitary formulations, such as anti-foaming agents, marking agents, anti-rebound agents, anti-drift agents, or mixtures thereof.
• the content of pH correcting agent is such that the composition, when it is in the form of an emulsion at 1% by weight in water, is between 5 and 9.
• composition can be used alone, as a complete phytosanitary composition (use in "built-in”).
• the composition may or may not comprise a phytosanitary active material whose action is similar or not to that of the composition.
• the active material can be chosen from insecticides in order to avoid the proliferation of aphids, while the composition according to the invention (comprising the combination of esters and a nonionic surfactant) has a limiting role virus transmission to the plant.
• the weight of the sprayer is noted before and after application by spraying on the plant: approximately 20 mL is sprayed on each plot of plant (area of 0.24 m 2 ). This corresponds to approximately a dose of 15 L of treatment per hectare.
• a plot of 30 plants is treated.
• a control plot of 30 plants is also preserved, without treatment, as well as another plot of 30 plants for the reference product (comparative example) of mineral origin (Luxan 11 H).
