Definitions
- plants have intrinsic means to defend themselves.
- biotic stress denotes stress that comes from living organisms such as pathogenic microorganisms, for example fungi, bacteria, viruses, but also nematodes, insects, mites herbivores, or parasitic plants.
- the term “elicitor” denotes a substance that is recognized by plants and activates a signaling cascade that leads the plant to mobilize its defenses.
- An elicitor is a substance capable, under certain conditions, of stimulating natural defense mechanisms. These natural defenses are directed against bio-aggressors (diseases, pests).
- the term "abietic stress” denotes a stress that results from the non-living such as water stress, salt stress, flooding stress, wind, heat stress. (cold, frost, heat shock), stress due to ultraviolet (solar radiation), stress related to nutrient deficiencies, stress injury, oxidative stress, osmotic stress, chemical stress.
- biostimulant or plant biostimulant is defined in accordance with the study commissioned by the Center for Studies and Foresight of the Ministry of Agriculture, Agri-Food and Forestry (MAAF) and financed by MAAF under Program 215 (Contract No. SSP-2013-094, Final Report - December 2014) entitled "Agricultural Stimulation Products to Improve the Biological Functionality of Soils and Plants" - Review of Available Knowledge and strategic recommendations ".
- a biostimulant is: "A material that contains a substance (s) and / or microorganism” whose function, when applied to plants or the rhizosphere, is to stimulate natural processes to improve / benefit the nutrient absorption, nutrient efficiency, tolerance to abiotic stress, and crop quality, regardless of the nutrient content of the biostimulant. ". (EBIC, 2014).
- biostimulants currently used are microorganisms, plant extracts or synthetic chemical compounds. However, the effectiveness of these biostimulants is not optimal.
- the first problem to be solved by the invention is that of developing compositions that contribute to the biostimulation of plants by certain effects.
- the goal is to develop alternative compositions that are able to promote plant resistance to abiotic stress more effectively than the compounds of the prior art.
- the goal is to stimulate certain natural processes to improve / benefit nutrient absorption, nutrient efficiency, abiotic stress tolerance, and crop quality with, in the case of nutrients in particular, for direct or indirect effect, the growth of the plant, and thus the improvement of the yield.
- a second problem to be solved by the invention is that of developing compositions that are capable of stimulating certain natural mechanisms to improve tolerance to biotic stress.
- a third problem to be solved by the invention is that of developing compositions that make it possible to limit the quantity applied of plant protection products while retaining the same effect as the standard doses.
- the third objective is to develop a composition that can be used as an adjunct phytosanitary composition in particular.
- the present invention addresses all of these technical problems. More specifically, the Applicant has found that these objectives were achieved by combining a nonionic surfactant derived from polyols and a sterol hereinafter referred to as "the composition or composition of the invention".
- the composition of the invention is used to promote the elongation of the main roots and the multiplication and elongation of the secondary roots, that is to say the growth of the main and secondary roots.
- the composition of the invention is used to promote flowering.
- the composition of the invention is used to promote the resistance of plants against abiotic stresses.
- the composition is used in particular to limit the loss of stomatal water, that is to say to allow the plant to better withstand water stress.
- the composition of the invention has a particular effect on the activation of the acquired systemic resistance system.
- the composition acts not only to stimulate natural defense mechanisms against biotic stress but also to promote resistance to abiotic stress.
- the fact that the composition of the invention is not a product with specific activity makes it possible to envisage broad-spectrum use on a large number of crops, which can save minor crops for which the number of phytosanitary products available is almost -no.
- the Applicant has found that the composition of the invention makes it possible to improve the spreading of liquids on the sheet, in particular of an aqueous solution. This phenomenon results from the reduction of the surface tension of the sheet in contact with the composition of the invention. It follows that by improving the spreading of a solution containing an active product with respect to the plant, the necessary amount of product is reduced for an equivalent effect.
- the invention also relates to the use of the composition as an adjuvant of a solution containing an active product vis-à-vis the plant.
- an active product it is possible to envisage in particular nutrients, one or more fertilizers, one or more growth regulators and / or with a biocontrol product.
- the biocontrol products are intended to prevent the action of plant pests and are chosen in particular from fungicides, fungicides, bactericides, bacteriostats, insecticides, acaricides, parasiticides, nematicides, taupicides or repellents for birds or game, one or more substances intended to destroy undesirable plants or to slow down their chosen growth, in particular among herbicides or antidicotyledons.
- composition of the invention thus constitutes an economy for the farmer that reduces the number of applications (of field trips). With its indirect mode of action, the product does not cause resistance.
- composition of the invention When used in combination with an active product vis-à-vis the plant as described above, it is simultaneously or sequentially.
- This type of synergy corresponds in all respects to the demands of society in terms of phytosanitary products:
- composition according to the invention may be applied after emergence or before emergence, on the seed, the seedling (juvenile stage prior to flowering), the plant during flowering (before, during or after pollination), the plant after fertilization, the plant being fruited, the fruit, flowers, leaves, stems, roots or soil, before or after sowing.
