    [0002] Use of a composition as a nematicide
    [0004] The present specification refers, as its title indicates, to a new use of a composition with phytosanitary activity, which comprises two active principles: cinnamic aldehyde and alcohol or terpenic alcohols, for its use as a nematicide in the agricultural field, especially in crops of bananas, plantains, table grapes and winemaking, fruit trees, citrus, strawberry and soy.
    [0006] Field of the invention
    [0007] The invention relates to the field of the use of phytosanitary products for the treatment against nematodes in agricultural crops, especially in crops of banana, plantain, table grape and winemaking, fruit trees, citrus, strawberry and soy.
    [0009] Current state of the art
    [0010] We will previously establish a series of definitions for a better understanding of this specification:
    [0011] Nematodes: multicellular worms that belong to the group of helminths. They can be found both in water and on land. In reference to the terrestrial ones, there are bacterivorous and fungivorous nematodes, predators of other nematodes, parasites of insects, of other animals and parasites of plants (phytoparasites). For the present report when we speak of nematodes we will refer to those that live in a terrestrial environment and have a parasitic activity of plants and are called in the agricultural field as "phytoparasitic nematodes".
    [0012] Terpene alcohol: in the present specification the term terpene alcohol is understood as that liquid product constituted mainly (more than 70.0% w / w) by a single monoterpene alcohol such as a-terpineol, or the multi-constituent mixture of terpene alcohols obtained essentially by monocyclic terpenic alcohols (terpineols, 1-terpinene-4-ol, etc.) and a lower proportion by tricyclic terpenic alcohols (phencho, borneol, etc.).
    [0014] Cinnamic aldehyde: organic compound with the name of the IUPAC (2E) -3-phenylprop-2-enal and other names such as cinnamic aldehyde or cinnamaldehyde whose developed formula is C 6 H 5 CHCHCOH and molecular formula is C 9 H 8 O. This compound It can be obtained from natural sources or by chemical synthesis.
    [0016] Ethoxylated castor oil: it is the castor oil obtained by reacting with ethylene oxide through an ethoxylation reaction. The various ethoxylated castor oils are classified based on the number of moles of ethylene or degree of ethoxylation.
    [0018] Ethoxylated castor oil with low degree of ethoxylation. Ethoxylated castor oil with a degree of ethoxylation between 5 and 20 moles.
    [0020] Ethoxylated castor oil with a high degree of ethoxylation. Ethoxylated castor oil with a degree of ethoxylation greater than 20.
    [0022] Calcium alkyl aryl sulfonate in solution: liquid product obtained by dissolving calcium alkyl aryl sulfonate at a final concentration between 45.0 and 70.0% w / w in a solvent.
    [0024] C11-C13 alcohols: liquid product with a minimum content of 80% w / w in ethoxylated branched C11-C13 alcohols with> 2.5 EO (EO = ethylene oxide) and characterized by a CAS number: 68439-54-3.
    [0025] Nematodes are one of the most serious problems faced by modern agriculture, which reduces the yield of agricultural crops as a result of their presence. One of the most serious symptoms that can cause is necrosis in the stem of newly planted crops, although others can also be observed, such as low vigor, poor vegetative development, decrease in production with significant economic losses, abnormal leaf colorations, general desiccation. of crops, and an abnormal appearance of the root system.
    [0027] At present, and as far as our knowledge reaches, there are a limited number of phytosanitary products both of chemical, natural or microbiological synthesis for the control of this disease worldwide. Many of the products on the market have had to be banned and withdrawn from the market due to their high toxicity to humans or the presence of toxic residues. This has caused farmers to have a great limitation in terms of the products to use with the consequent economic losses. Therefore, there is a great demand in the sector for new nematicides that are very effective and also provide a substantial improvement in aspects such as toxicology, application safety and the reduction or absence of residues, giving rise to very important environmental and economic advantages for the agricultural sector.
    [0029] Background of the invention
    [0030] At present, some products and procedures for the treatment of nematodes are known, such as those described in patents ES2033195 "Improved pesticidal composition and procedure to prepare it" and ES2012284 "Procedure for the preparation of new N-trichloromethylthioderivatives with biocidal activity" , but they present the problem of using highly toxic organophosphate products or chlorinated derivatives, highly questioned at this time due to their environmental impact and not very advisable for food products for direct consumption
    [0032] Some product for agricultural uses that uses aromatic aldehydes is also known, such as that described in patent EP0889691 "Use of aromatic aldehydes as a pesticide" but using a completely different composition, with low effectiveness, and whose use is not the one described in the present invention, if not merely fungicide. In the same way, patent WO2013040721 describes "Process and system for the manufacture of ozonated natural oils, and their application in the treatment of humans, plant animals and in aquaculture" a use with a product completely different, with low effectiveness.
    [0034] On the other hand, patent US2014323583 "Cinnamaldehyde and diallyl disulfide formulations and methods of use" describes the use of cinnamic aldehyde as a nematicide. However, it shows a synergistic complex of cinnamic aldehyde and dialyl disulfide where the two substances are necessary for the application. Furthermore, the cinnamic aldehyde is in concentrations much higher than those described herein and is used in tomato, cucurbit and melon crops while the present invention does not contain diallyl disulfide nor the target cultures are the same and with different problems in terms of to the type of nematodes.
    [0036] Similarly, patent KR100941915 "Anti-pinewood nematode compound containing cinnamaldehyde extracted from Cinnamomum cassia and its structurally-similar compounds", describes a nematicidal composition for use in the pine conifer and with a way of use and cultivation very different from that described. in this memory.
    [0038] Patent US4978686 "Method of protecting crops by a non-toxic composition" describes the combined and necessary use of cinnamic aldehyde with an antioxidant.
    [0040] Finally, patents ES2163999 "Composition of natural origin to control postharvest pathology of fruits and vegetables and method of application", ES2328322 "Compositions of natural origin to treat pathogens and diseases produced by pathogens of fruits and vegetables, after their harvest. , and a method for its application " and ES2682963 " Fungicidal composition for the treatment of banana and / or plantain " describe the use of cinnamic aldehyde and terpene alcohol for a use merely as a fungicide, very far from the use recommended in this invention.
    [0042] Description of the invention
    [0043] To solve the current problem in the protection against nematodes in the agricultural field, especially in crops of banana, plantain, table grapes and winemaking, fruit trees, citrus, strawberry and soy, improving the current state of the art, The new use of a composition as a nematicide, not used until now in this field of application, has been devised. This composition comprises two materials as active principles, cinnamic aldehyde and terpenic alcohols combined with ethoxylated castor oil, C11-13 alcohols and calcium alkyl aryl sulfonate in solution.
    [0045] Cinnamic aldehyde is one of the two active principles with nematicidal activity, which is combined with terpene alcohol as a compound that has a double function: to act as a nematicidal active principle and to improve the application of the product, acting as a soil adjuvant improving penetration and dispersion of the product in the soil and allowing to reach the nematodes distributed at the root level.
    [0047] The composition is formulated as an emulsifiable concentrate for the preparation of liquid phytosanitary formulations for the treatment of nematode problems in various agricultural crops. This composition, used up to now as a fungicide, has been surprisingly effective in the treatment of nematodes in banana, plantain, table grape and wine crops, fruit trees, citrus, strawberry and soy, according to the experimental tests carried out.
    [0049] Its use is preferably by fertigation or drench application. A product application rate of between 1.5 l / ha and 10.0 l / ha is used, preferably between 2.5 l / ha and 7.5 l / ha.
    [0051] Advantages of the invention
    [0052] This novel use of the phytosanitary composition for the treatment against problems of banana and plantain nematodes, of table grapes and winemaking and of fruit, citrus, strawberry and soy trees that is presented provides multiple advantages over currently available products, the most important being that it has a high efficacy against nematodes in indicated crops compared to products of chemical or natural synthesis that are currently known for use in these horticultural crops.
    [0054] It is important to highlight the advantage that the use of this composition has a very positive toxicological profile according to international standards compared with other products of chemical synthesis, thanks to the use of the active principles cinnamic aldehyde and terpenic alcohols. This can lead to declare this composition as free of phytosanitary residues with the clear agricultural, sanitary, economic and environmental advantages compared to synthetic products.
    [0056] In addition, it is necessary to highlight the advantage that the use of this nematicidal composition originates since it does not incorporate antioxidants, as is usual in other compositions with similar substances. This is due to the fact that the composition used ensures that the structure is maintained and the degradation of the active cinnamic aldehyde product by oxidation is avoided, giving rise to a stable product according to international standards for this type of product. As a consequence, the introduction of antioxidant substances that can act as pollutants is avoided, thus minimizing toxicity to humans or phytotoxicity to plants of the composition.
    [0058] Another important advantage of this use is that it also incorporates another substance with nematicidal activity, terpenic alcohols, which has a double function; On the one hand, the nematicidal efficacy per se is increased , and on the other, the effectiveness regarding the application of the product is increased since they contribute by acting as a soil adjuvant, improving the penetration and dispersion of the product in the soil and allowing to reach the distributed nematodes. at the root level.
    [0060] Another advantage of this new use of the nematicidal composition is cheaper compared to traditional chemical phytosanitary products.
    [0062] Preferred embodiment of the invention
    [0063] The presented use of the composition consists of carrying out a phytosanitary treatment against nematodes in the agricultural field, especially in crops of banana, plantain, table grape and winemaking, fruit trees, citrus, strawberry and soy.
    [0065] The composition used basically comprises:
    [0067] - Cinnamic aldehyde (active matter),
    [0068] - Terpenic alcohols (active matter),
    [0069] - Blend of ethoxylated castor oils with a high degree of ethoxylation,
    [0070] - Ethoxylated castor oil with low degree of ethoxylation,
    [0071] - Alcohols C11-13,
    [0072] - Calcium alkyl aryl sulfonate in solution.
    [0074] The cinnamic aldehyde is present in a proportion comprised between 20.0% and 45.0% by weight, preferably 25.0-35.0% by weight, relative to the total weight of the composition.
    [0076] Terpenic alcohols, for example α-terpineol, are found in a proportion of between 5.0% and 10.0% by weight, preferably between 6.0% and 8.0% by weight, with respect to the total weight of the composition.
    [0077] The ethoxylated castor oil blend comprises at least two ethoxylated castor oils with a high degree of ethoxylation. The degree of ethoxylation of these oils is between 20 and 40 moles, preferably between 30 and 40 moles, and more preferably chosen from the group consisting of 35, 36 and 40 moles. This mixture of ethoxylated castor oils with a high degree of ethoxylation is in a proportion between 20.0% and 40.0% by weight, preferably between 25.0% and 35.0% by weight, with relative to the total weight of the composition.
    [0079] On the other hand, at least one ethoxylated castor oil with a low degree of ethoxylation is also used. The degree of ethoxylation of this oil is between 5 and 20 moles, preferably between 8 and 15 moles, and more preferably between 9 and 10 moles. This ethoxylated castor oil with a low degree of ethoxylation is in a proportion comprised between 0.4% and 2.0% by weight, preferably between 0.5% and 1.0% by weight, with respect to the total weight of the composition.
    [0081] The C11-13 alcohols are found in a proportion comprised between 25.0% and 40.0% by weight, preferably between 30.0% and 35.0% by weight, relative to the total weight of the composition. .
    [0083] Calcium alkyl aryl sulfonate in solution is in a proportion of between 1.0% and 5.0% by weight, preferably between 1.5% and 2.0% by weight with respect to the total weight. of the composition.
    [0084] The use of this composition as a nematicide is carried out by fertigation, by drenching or in a band at the bottom of the furrow during planting. An application rate of the product is used between 1.5 l / ha and 10.0 l / ha, preferably between 2.5 l / ha and 7.5 l / ha.
    [0086] The experimental tests carried out with the use of this phytosanitary composition with nematicidal action in various crops, especially in crops of banana, plantain, table grape and winemaking, fruit trees, citrus fruits, strawberries and soybeans, have made it possible to verify its remarkable effectiveness against nematodes.
    [0088] Application conditions and results obtained experimentally in the field
    [0090] To reflect the efficacy of the invention described herein, experimental studies were conducted in the laboratory and under commercial conditions.
    [0092] The experimental studies carried out have surprisingly proven how the substance added as soil adjuvant, terpenic alcohols, have shown nematicidal efficacy. In this way, the combined use of cinnamic aldehyde and terpenic alcohol give rise to a formulation with a notable improvement in its efficacy and / or the agronomic results obtained.
    [0094] Example 1: Study of the nematicidal efficacy of the formulations and of the raw materials cinnamic aldehyde and terpenic alcohol.
    [0096] The objective of the protocol was to evaluate the nematicide of the formulation and the active ingredients separately, cinnamic aldehyde and terpenic alcohol. The nematodes M. icognita and M. javanica were used for this test .
    [0098] Treatments:
    [0100] 1. Untreated witness. Eggs or juvenile nematodes in sterile water.
    [0101] 2. Eggs or juveniles with 0.025% of the formula in sterile water.
    [0102] 3. Eggs or juveniles with 0.05% of the formula in sterile water.
    [0103] 4. Eggs or juveniles with 0.1% of the formula in sterile water.
    [0104] 5. Eggs or juveniles with 0.025% terpene alcohol in sterile water plus harmless solvent.
    [0105] 6. Eggs or juveniles with 0.05% terpenic alcohol in sterile water plus harmless solvent.
    [0106] 7. Eggs or juveniles with 0.1% terpenic alcohol in sterile water plus harmless solvent.
    [0107] 8. Eggs or juveniles with 0.025% cinnamic aldehyde in sterile water plus harmless solvent.
    [0108] 9. Eggs or juveniles with 0.05% terpenic alcohol in sterile water plus harmless solvent.
    [0109] 10. Eggs or juveniles with 0.1% terpenic alcohol in sterile water plus harmless solvent.
    [0111] Results:
    [0113] The treatments with juveniles hatched at 0 h, 24 h, 48 h and 72 h. The number of hatched eggs was determined approximately every 72 h for 3-4 weeks. At the end of the juvenile counts, the solutions were removed in each of the wells, washed several times in sterile water to remove the tested compounds, and the mobility of the juveniles in sterile water was estimated at 24 h. This made it possible to determine whether the tested compounds have any nematode or hatching inhibition effect. All counts were made by stereomicroscope.
    [0115] Juvenile mortality
    [0117] For the formulation of the present invention : the mortality of J2 in both species was similar and 100.0% was reached with all treatments in less than 24 h. The subsequent withdrawal of the product and the 24-hour observation did not confirm mobility in the immobile juveniles, which were considered dead and there was no nematode activity (induction of inactivity in juveniles). It was also observed that the membranes of the juveniles showed ruptures and disintegration, in some cases with internal material of the nematode coming out in the dead juveniles.
    [0119] For cinnamic aldehyde and terpenic alcohol : the mortality of J2 in M incognita reached 100.0% in all concentrations of cinnamic aldehyde in less than 24 h, while with terpenic alcohol a 50.0% was achieved at 24 h h.
    [0121] Egg hatching
    [0123] For the formulation of the present invention : a significant reduction in hatching is observed in both species with the formulation tested. Microscopic observations show high variability with the morphology of the tested eggs after treatment. A significant disorganization of the eggs is only observed in some of them by observing some alive.
    [0124] For cinnamic aldehyde and terpenic alcohol : the hatching of the eggs of M incognita had similar results to those obtained with the juveniles. Cinnamic aldehyde inhibited hatching of juveniles at all concentrations tested. However, terpenic alcohol was effective over 25.0%.
    [0125] The conclusions of the example indicate that the composition shows very good results in laboratory experimentation. These results show that both active ingredients have nematicidal efficacy.
    [0126] Example 2: Study of the nematicidal efficacy of the formulations and of the cinnamic aldehyde and terpenic alcohols raw materials.
    [0127] The objective of the protocol was to evaluate the effect of the agricultural composition of the present invention applied as a nematicide in table grapes against the nematodes Rotylenchulus sp, and Helicotylenchus sp. Place: Peru. Variety: Crimson.
