    [0001] Use of a fungicidal composition as an oidium treatment This description refers, as its title indicates, to a new use of a composition with fungicidal phytosanitary activity, whose active substance is cinnamic aldehyde combined with terpenic alcohol, for the treatment against disease known as oídio, in horticultural crops, especially from the cucurbitaceae family, and more specifically melon, watermelon, cucumber and zucchini, as well as the cultivation of pepper, strawberry and raspberry.
    [0002] Field of the Invention
    [0003] The invention relates to the field of the use of phytosanitary products for the treatment against oidium in horticultural crops, especially of the cucurbitaceae family, such as melon, watermelon, cucumber and zucchini, the cultivation of pepper, strawberry and raspberry.
    [0004]
    [0005] Current state of the art
    [0006] We will establish previously a series of definitions for a better understanding of this descriptive memory: Oídio: Disease caused by a parasitic fungus whose vegetative apparatus forms on the leaves of the plants a network of whitish and dusty filaments. There are many different types but in the case of cucurbitaceae the causative fungus is called Spaerotheca fuliginea, for the strawberry Sphaeroteca macularis, for the pepper it is Sphaeroteca Erisiphales and for the raspberry it is Podosphaera aphanis.
    [0007] Cinnamic aldehyde: Organic compound with the name of IUPAC (2E) -3-phenylprop-2-enal and other names such as cinnamic aldehyde or cinnamaldehyde whose formula developed is C6H5CHCHCOH and molecular formula is C9H8O. This compound can be obtained from natural sources or by chemical synthesis.
    [0008] Ethoxylated castor oil: Castor oil obtained by reacting with ethylene oxide through an ethoxylation reaction. The various ethoxylated castor oils are classified according to the number of moles of ethylene or degree of ethoxylation.
    [0009] Ethoxylated castor oil with low degree of ethoxylation. Ethoxylated castor oil with ethoxylation degree between 5 and 20 moles.
    [0010] Ethoxylated castor oil with high degree of ethoxylation. Ethoxylated castor oil with an ethoxylation degree greater than 20.
    [0011] Alkyl calcium aryl sulfonate in solution: Liquid product obtained by dissolving calcium alkyl aryl sulphonate at a final concentration between 45 and 70% weight / weight in a solvent.
    [0012] C11-C13 alcohols: Liquid product with a minimum content of 80% weight / weight in ethoxylated branched C11-C13 alcohols with> 2.5 eO and characterized by a CAS number: 68439-54-3.
    [0013] Terpenic alcohol: The term terpenic alcohol is understood herein as that liquid product constituted mostly (more than 80% weight / weight) by a single monoterpene alcohol such as atherpineol, or the multiconstituent mixture of terpenic alcohols obtained essentially by alcohols monocyclic terpenes (terpineols, 1-terpineno-4-ol, etc.) and a smaller proportion for tricyclic terpenic alcohols (fencho, borneol, etc.).
    [0014] The powdery mildew is a disease that, depending on the crop, is caused by different types of fungi. It is a foliar disease that represents a very important limitation in the production of cucurbitaceae, especially melon, watermelon, cucumber and zucchini, as well as in the cultivation of pepper, and strawberry and raspberry worldwide. The disease affects the photosynthetic leaf area of the plant, even affecting the product of the plant and, consequently, the total production and quality of the crop.
    [0015] At present and as far as our knowledge reaches there are a limited number of phytosanitary products both chemical, natural or microbiological synthesis for the control of this disease worldwide. This has caused the appearance of resistance by the fungus against the treatment of these products, and giving rise to the need for combined uses of these phytosanitary products, as well as the appearance of high levels of phytosanitary residues in the fruits and a poor control of the powdery land with the consequent economic losses. Therefore, if new fungicides could be found whose composition is very effective and also provide an improvement in toxicology, application safety and Reduction or absence of waste could generate very important environmental and economic advantages for this crop.
    [0016]
    [0017] Background of the invention
    [0018] At present, some procedures and products for the treatment of powdery mildew are known, such as those described in patents ES0178125 "A procedure for obtaining a product against peronospora and vineyard powder, applicable with a single treatment", ES8504435 "Procedure for obtaining a paste for the fight against powdery mildew", and EP1754412 "Procedure for the biological treatment of vegetables, in particular vine and adapted compositions", but present the problem of using sulfur, with a high environmental impact and not very advisable for food products for direct consumption.A product that uses aromatic aldehydes, such as the one described in patent EP0889691 "Use of aromatic aldehydes as a pesticide" but using a completely different composition, with low effectiveness is also known.
    [0019] In the same way it is described in patent WO2013040721 "Process and system for the manufacture of ozonized natural oils, and their application in the treatment in humans, plant animals and aquaculture" a completely different product use, with low effectiveness.
    [0020] Finally, in WO2010086103 "Use of succinate dehydrogenase inhibitors to control primary infections by oidium" the use of fluopiram is recommended to control primary infections by oidium in perennial crops, in which fluopiram was applied to perennial culture before end of the previous vegetative cycle.
    [0021]
    [0022] Description of the invention
    [0023] To solve the current problem in the protection against horticultural crops such as cucurbitaceae, especially melon, watermelon, cucumber and zucchini, pepper, strawberry and raspberry, improving the state of the art, the new use of a fungicidal composition, not used until now in this field of application. This fungicidal composition comprises as an active ingredient cinnamic aldehyde, combined with ethoxylated castor oil, C11-13 alcohols, calcium aryl alkyl sulfonate in solution and terpenic alcohols,
    [0024] Cinnamic aldehyde is the active substance with fungicidal activity, which is combined with terpenic alcohols as a compound to improve the application of the product, its resistance on the leaves and its effectiveness.
    [0025] The composition is formulated as an emulsifiable concentrate for the preparation of liquid formulations of fungicides for the treatment of powdery mildew, especially melon, watermelon, cucumber and zucchini, the cultivation of strawberry and raspberry pepper.
    [0026] This fungicidal composition, despite being specifically designed for the treatment against the Sigatoka of banana and / or plantain, and being used only for it, has been surprisingly effective also for the treatment of powdery mildew in horticultural crops, according to experimental tests made.
    [0027] Its use is preferably by ground spraying with manual sprayers, motor pumps, or other similar means. A dose of application of the product between 0.05 l / hl and 0.5 l / hl., Preferably between 0.2 l / hl and 0.3 l / hl, is used.
    [0028]
    [0029] Advantages of the invention
    [0030] This novel use of the fungicidal composition for the treatment against the powdery mildew of the cucurbits, especially melon, watermelon, cucumber and zucchini, the cultivation of pepper, strawberry and raspberry that is presented provides multiple advantages over the products currently available being the most important one that has a high efficacy against powdery mildew in the indicated crops against chemical or natural synthesis products that are currently known for use in these horticultural crops.
    [0031] It is important to highlight the advantage that the use of this composition has a very positive toxicological profile according to international standards compared to other chemical synthesis products, thanks to the use of the active substance cinnamic aldehyde. This may lead to declaring this composition as free of phytosanitary residues with the clear agricultural, sanitary and economic advantages over synthetic products.
    [0032] In addition, it is necessary to highlight the advantage caused by the use of this fungicidal composition since it does not incorporate antioxidants, as is usual in other compositions with similar substances. This is because the The composition used ensures that the structure is maintained and the degradation of the active product by oxidation is avoided, resulting in a stable product according to international standards for this type of products. As a consequence, the introduction of antioxidant substances that can act as contaminants or by increasing the toxicity or phytotoxicity of the composition is avoided.
    [0033] Another important advantage of this use is that, by incorporating terpenic alcohols, the efficiency in the application of the product is increased since they contribute to maintaining the substance on the leaves of the plant, resisting even in the rain.
    [0034] It should also be noted that the use of terpenic alcohols reduces the amount of mineral oil that needs to be added, thus significantly reducing the toxicity produced by these oils in horticultural crops.
    [0035] Another advantage of this new use of the fungicidal composition is that, in addition to the advantages already indicated in terms of improvement of the toxicological profile, presumable absence of residues, absence of antioxidant substances that can act as contaminants, improvement in application, improvement In fact, the decrease in toxicity of other application aids is that it is economically competitive against traditional chemical phytosanitary products.
    [0036]
