    [0002]
    [0003]
    [0004] Field of the Invention
    [0005]
    [0006] The present invention is framed within the agri-food sector. It refers to the use of lecithins as substances with the capacity to negatively affect the integrity of arthropod species, more specifically capable of acting as insecticides or acaricides.
    [0007]
    [0008] Background of the Invention
    [0009]
    [0010] To date, although it is true that there are abundant written references to the use of soy lecithin as a fungicidal or fungistatic agent, in no case has any description of lecithins been found, as they are chemically or physically extracted from their original matrices, such as substances capable of acting or negatively affecting the development of insects or mites.
    [0011]
    [0012] In the market there are formulated concentrates of emulsified lecithins (EUROPEAN COMMISSION, DIRECTORATE-GENERAL FOR HEALTH AND FOOD SAFETY, Safety of the Food Chain, Pesticides and Biocides, SANCO / 12798/2014-rev. 2; 30 March 2015)), are suspensions of lecithin in oils with maximum riches of 49% w / V. The use of these commercial concentrated lecithin suspensions is indicated as a fungicide or as an adjuvant.
    [0013]
    [0014] However, it is very difficult, if not impossible, to reach high concentrations of lecithin with these emulsifiers. The liquid becomes very viscous and commercially useless.
    [0015]
    [0016] Furthermore, the soluble powder format - which is standardized in the agricultural environment - or the wettable powder of lecithin has never been described in the agricultural sector. In this sense, it has not been possible so far to be able to obtain lecithin powder among agricultural supplies.
    [0017] On the other hand, until now it has not been economically feasible to reach an optimal concentration for acaricide / insecticide use based on concentrated suspensions of lecithins. It is not economically feasible to reach liquid compositions, application broths, with a concentration of 30 g / l (30 grams of lecithin per liter of composition) starting from these suspensions.
    [0018]
    [0019] In order to have a lecithin concentration sufficient for use against arthropods in a liquid composition, ready for application, starting from concentrated emulsifiers, an amount of emulsifier would be necessary such that it makes the use of lecithins not economically viable .
    [0020]
    [0021] Therefore, there are several needs in the state of the art, on the one hand, the development of new biocides with insecticidal and acaricidal capacities, which are environmentally friendly, harmless to humans, economically sustainable and respectful of the mechanisms of Biological control fully integrated in agricultural development, and on the other hand, compositions that contain lecithin in the desired effective and effective concentration and that are economically viable for use in phytosanitary or nutritional applications in the environment of the agricultural sector.
    [0022]
    [0023] Surprisingly it has been found that lecithins have biocidal properties against arthropods, in particular they have insecticidal and acaricidal properties. It has further been found that it is possible to achieve necessary concentrations of lecithin in a composition that can be used against arthropods, such as insects and mites. Furthermore, it has been found that it is not necessary to use a lecithin emulsion as the starting raw material, which is precisely one of the reasons why it was not hitherto economically viable to prepare compositions effective against arthropods. The present invention also solves this problem by having been able to prepare liquid compositions using lecithin powder - for example, soluble powder or wettable powder - as a starting product, this point being an innovative aspect and an advantage over the state of the art, since that to date, there was no lecithin powder format in the agricultural sector for the preparation of liquid compositions ready to be applied in the field.
    [0024] In addition to the aforementioned advantages, the use of inert substances in formulations of lecithin powder, soluble powder, or wettable powder, provide improvements over lecithin alone in terms of preservation and manageability.
    [0025]
    [0026] Description of the Invention
    [0027]
    [0028] In the present invention, the term "lecithins" refers to a family of emulsifying and saponifiable lipids that occur naturally in animal and plant tissues, the general formula of which is as follows:

    [0030]
    [0031]
    [0032]
    [0033] The term "arthropods" refers to invertebrate animals that form the most diverse phylum in the animal kingdom. These animals have their bodies covered by an exoskeleton known as a cuticle and forming a linear series of ostensible segments, with appendages of articulated pieces. Arachnids, insects, and crustaceans are arthropods.
    [0034]
    [0035] The term "insects" refers to a class of invertebrate animals of the arthropod's edge, characterized by presenting a pair of antennas, three pairs of legs and two pairs of wings.
    [0036]
    [0037] The term "mites" refers to a subclass of arachnids encompassed by the arthropod edge.
    [0038]
    [0039] The term "formulated" refers to a solid product that comprises lecithin powder - soluble powder or wettable powder - and that optionally can comprise one or more inert substances. This term is used because it is commonly used in agriculture-related technology and in products that are applied as biocides or biopesticides.

    [0105]
    [0106] Examples:
    [0107]
    [0108] Example 1
    [0109]
    [0110] Tests have been carried out with soy lecithin and sunflower lecithin. For this, 100% rich lecithin powder, that is, pure lecithin powder, was used as the starting product.
    [0111]
    [0112] Each formulation of each class of lecithin was tested at different concentrations, expressed in grams of lecithin for each liter of water: 0.5 g / l, 1 g / l, 2 g / l, 4 g / l, 8 g / l 16 g / l.
    [0113]
    [0114] The acaricidal or insecticidal activity of lecithins in their different concentrations were evaluated against one mite and two insects, considered a pest in horticultural crops globally:
    [0115]
    [0116] - Tetranychus urticae, plague mite commonly called "red spider"
    [0117] - Frankliniella occidentalis, phytophagous insect commonly called "trips".
    [0118] - Aphis fabae, aphid.
    [0119]
    [0120] The acaricidal and / or insecticidal activity of the lecithin formulations (100% lecithin) of the example was evaluated in both the adult and immature stages of the three pests used.
    [0121]
    [0122] The acaricidal or insecticidal activity was determined in terms of percentage of mortality or mortality efficiency of red spider, thrips and aphids. Negative controls, that is, populations of spider, thrips or of healthy aphids to which only treatments with distilled water were applied.
    [0123]
    [0124] The mortality efficiencies obtained from each treatment, from each composition and at each concentration in each pest tested were subjected to the Henderson-Tilton correction, with the following formula:
    [0125]
    [0126] % Henderson-Tilton efficiency = [1- (Td / Cd) x (Ca / Ta)] x 100
    [0127] Where:
    [0128]
    [0129] Ta = n ° live individuals in the treatment before application.
    [0130] Td = n ° individuals alive in the treatment after the application.
    [0131] Ca = n ° live individuals in the control before application.
    [0132] Cd = n ° live individuals in the control after application.
    [0133]
    [0134] The corrected mortality efficacy results obtained were subjected to statistical tests in order to verify the statistical significance of the results.
    [0135]
    [0136] Table 1 reflects the summary of Henderson-Tilton corrected efficacy results obtained in the different tests by the different lecithins, in their different formulations and at the different concentrations on the three pests used in the test:

    [0139] Table 1. Efficacy results for mortality corrected according to Henderson-Tilton in% obtained in the different tests.
    [0140]
    [0141] All the corrected mortality efficiencies obtained were found to be statistically significant with a significance level of 95%, therefore all the compositions tested were shown to have insecticidal and / or acaricidal activity at the doses tested.
    [0142]
    [0143] Both soybean and sunflower lecithin compositions have been shown to have insecticidal and / or acaricidal activity on the pests used in the test, in their different formulations and in different concentrations. This activity manifests itself in the different phases of the life cycle of the insects and mites tested and would allow, to a certain extent, to control the pests tested in field conditions.
    [0144]
    [0145] Example 2.
    [0146]
    [0147] Tests have been carried out with soy lecithin mixed with chitosan as an inert matter as a method of improving the solubility of the product in water. For this, solid lecithin powder was used as the starting product and it was mixed with chitosan powder in a ratio of 3: 1 w / w, that is, 3 parts of lecithin and 1 of chitosan, thus, lecithin powder tested against various insects and mites it had a final richness of 75% by weight of lecithin on the total and 25% by weight of chitosan on the total
    [0148]
    [0149] This 75% lecithin was tested at different concentrations, expressed in final grams of lecithin for each liter of water: 0.5 g / l, 1 g / l, 2 g / l, 4 g / l, 8 g / l and 16 g / l.
    [0150] The acaricidal or insecticidal activity of lecithin in its different concentrations was evaluated against a mite and two insects, considered pests in horticultural crops globally:
    [0151]
    [0152] - Tetranychus urticae, plague mite commonly called "red spider"
    [0153] - Frankliniella occidentalis, phytophagous insect commonly called "trips". - Aphis fabae, aphid
    [0154] The acaricidal and / or insecticidal activity of the lecithin formulations of this example was evaluated in both the adult and immature stages of the three pests used.
    [0155]
    [0156] The acaricidal or insecticidal activity was determined in terms of percentage of mortality or mortality efficiency of red spider, thrips and aphids. Negative controls were included in the trials, that is, healthy spider, thrips or aphid populations that were only treated with distilled water.
    [0157]
    [0158] The mortality efficiencies obtained at each concentration in each pest tested were subjected to the Henderson-Tilton correction, with the following formula:
    [0159]
    [0160] % Henderson-Tilton efficiency = [1- (Td / Cd) x (Ca / Ta)] x 100 Where:
    [0161]
    [0162] Ta = n ° live individuals in the treatment before application.
    [0163] Td = n ° individuals alive in the treatment after the application.
    [0164] Ca = n ° live individuals in the control before application.
    [0165] Cd = n ° live individuals in the control after application.
    [0166]
    [0167] The corrected mortality efficacy results obtained were subjected to statistical tests in order to verify the statistical significance of the results.
    [0168]
    [0169] Table 2 reflects the summary of Henderson-Tilton corrected efficacy results obtained in the different trials by lecithin of 75% richness at the different concentrations on the three pests used in the trial:
    [0170]
    [0171]

    [0173]
    [0174]
    [0175] a) final lecithin concentrations (grams of lecithin per liter of water)
    [0176]
    [0177] Table 2.
    [0178]
    [0179] All the corrected mortality efficiencies obtained were found to be statistically significant with a significance level of 95%, therefore all concentrations were shown to have insecticidal and / or acaricidal activity at the doses tested.
    [0180]
    [0181] Compositions of soy lecithin and chitosan as inert matter in the ratio 3: 1 have been shown to have insecticidal and / or acaricidal activity on the pests used in the test at different concentrations. This activity manifests itself in the different phases of the life cycle of the insects and mites tested and allows to exercise, to a certain degree, control of the pests tested in field conditions. On the other hand, these efficiencies have been found to be equivalent to those obtained with the use of pure soy lecithin and dissolved in water at the same final concentrations.
