    METHOD FOR INCREASING TOLERANCE TO ABIOTIC ENVIRONMENTAL STRESS, REDUCING DAMAGE TO ABIOTIC STRESS OR IMPROVING THE QUALITY AND / OR PERFORMANCE AND / OR FORCE OF A PLANT CULTURE UNDER IRRIGATION WITH 1-MCP
    Field of the Invention
    The present invention relates to methods for increasing the tolerance to environmental stress of a plant, to methods for improving the quality and / or yield of a plant culture, to methods for applying agrochemicals that have a physiological effect on a plant, and cultures produced using these methods.
    Background
    The agrochemical industry is continually looking for methods to improve plant growth. Chemicals are typically used to control unwanted species, such as insects or vegetation (for example, herbs or fungi) and to promote plant growth (for example, by providing nutrients), thereby improving the growth of plants.
    In addition to the direct damage caused by external factors such as pests, or the lack of nutrients, the growth of a plant is affected, often adversely, by the plant's own responses to external environmental stressors. When subjected to such stress factors, plants exhibit a variety of mechanistic responses as protective measures, with an adverse effect resulting in growth, development and productivity. Significant losses in quality and yield are commonly observed.
    One of the key responses exhibited by plants in response to stress is the production of the ethylene plant hormone, which causes a variety of plant physiological effects, such as senescence, inhibition of root growth and inhibition of stem growth. Ethylene also acts to accelerate the process of fruit ripening, flower opening and leaf abscission. The synthetic plant growth regulator 1methylcyclopropene (1-MCP) blocks the effects of ethylene is used commercially

    2/17 to delay the ripening of fruit in stored fruits and vegetables and maintain the freshness of cut flowers, potted flowers, foliage plants, nursery and bed. The compound is a gas and must be used in the spaces involved to be effective. It is approved in the US and other places for use in enclosed spaces, such as greenhouses, storage rooms, refrigerators, closed truck trailers, controlled atmosphere food storage facilities and transport containers. It is also being developed as a post-emergence sprinkler in efforts to protect field crops during extended periods of extreme temperatures, drought and other stresses (Farm Industry News, Jan 18, 2008).
    EP Patent Document 0.220.514 refers to compositions comprising phytohormones and their use in methods to increase the quantity and quality of plant fruits or flowers in horticulture and agriculture. The International Patent Application document WO 2005/018319 refers to the application of auxins to the roots by drip irrigation or spray application in order to inhibit insect infestation.
    There is a need for additional methods to deal with the environmental stresses experienced by plants in order to increase their tolerance to this and to improve the quality and yield of a plant culture subject to these stresses.
    Summary of the Invention
    It has been observed that surprisingly the application of at least one cyclopropene that has a physiological effect on a plant, in the irrigation water, increases the tolerance to environmental stresses resulting in a plant culture that has an improved quality and / or an increased yield.
    Consequently, in a first aspect, the present invention provides a method for increasing the tolerance to environmental stress of a plant which comprises the application of at least one cyclopropene in the plant's irrigation water, said cyclopropene having a physiological effect on the plant .

    When describing the invention in general terms, reference will now be made to the attached drawing in which:
    Figure 1 illustrates wheat plants grown in bags. The plants on the right side are treated with 1-MCP and on the left side, they are untreated verification plants.
    Detailed Description
    In one embodiment, suitable cyclopropenes are gaseous at room temperature and are selected from a compound of formula I:
    (R) n - (D where n is a number from 1 to 4, suitably, n is a number from 1 to 2, and more appropriately n is 1. The variable group R is selected from hydrogen , C 1 to C 4 saturated or unsaturated alkyl, hydroxy, halogen, alkoxy, amino and carboxy in one embodiment, R is methyl.
    In one embodiment, the cyclopropene gas is selected from cyclopropene, dimethylcyclopropene and 1-methylcyclopropene (1-MCP).
    In one embodiment, 1-methylcyclopropene can be applied as a single ingredient, or alternatively, it can be in the form of an agrochemical composition comprising an agrochemical acceptable diluent or carrier. References in this document to 1-methylcyclopropene or components comprising said compounds should be considered for including 1-methylcyclopropene as a single ingredient or agrochemical compositions thereof.
    In one embodiment, 1-MCP is provided in an agrochemical composition that comprises a molecular encapsulating agent suitable for gaseous 1-MCPs such as cyclodextrins that include acyclodextrin.
    The solid complex of the cyclopropene gas and a molecular encapsulating agent is sometimes referred to herein as a cyclopropene complex.
    For example, in a method of making a cycle complex Petition 870190097729, of 9/30/2019, p. 15/32
    4/17 propene in which 1-MCP is encapsulated in a molecular encapsulating agent, the 1-MCP gas is bubbled through a solution of αcyclodextrin in water, from which the complex precipitates first and is then isolated by filtration. Cyclopropene complexes made using the above method are isolated, dried and stored in solid form, for example, as a powder containing active ingredient.
    In a further aspect, the present invention provides a method of reducing damage to a plant caused by one or more environmental stressors, which comprises the application of 1-MCP in the plant's irrigation water in which 1-MCP has a physiological effect on the plant.
    In a further aspect, the present invention provides a method for improving the quality of a plant culture which comprises the application of 1-MCP in the plant's irrigation water in which said agrochemical has a physiological effect on the plant.
    In a further aspect, the present invention provides a method for improving the yield of a plant culture which comprises the application of 1-MCP in the irrigation water of the plant in which said agrochemical has a physiological effect on the plant.
    In a further aspect, the present invention provides a method for improving plant vigor which comprises the application of 1-MCP in plant irrigation water, wherein said agrochemical has a physiological effect on the plant.
    Controlling the amount of 1-MCP that a plant receives is very difficult because it is a gas (e.g. <5 ° C), which is commonly applied as a spray application. Its volatility provides only a short residence time in a plant, since evaporation is fast. As a consequence, the maximum benefit cannot be achieved, which would otherwise be the case with less volatile agrochemicals. A higher than desired portion of the material is therefore wasted with unwanted losses to the environment.
    It was surprisingly found that the application of 1-MCP in irrigation water increases the plant's tolerance to environmental stresses.
    Petition 870190097729, of 09/30/2019, p. 16/32
    5/17 In particular, greater control over the amount of material administered to the plant can be achieved. There is significantly less waste and the risk of damage to the operator or the environment is reduced. Sprinkling problems moving unintentionally to other crops are eliminated.
    Instead of the repeated sprinkling of materials that are both labor-intensive as well as expensive, the much simpler and more targeted application is achieved. The concentration of 1-MCP in the irrigation water can be much lower than that of a spray and continuous and controlled application can be achieved. Formulation problems are also reduced, as effective concentrations can be achieved despite the low solubility in water of 1-MCP (137mg l-1). The quantities of agrochemicals transported to farms and on a farm are reduced, which, without further ado, already provides environmental benefits.
    The concentration of 1-MCP in the irrigation water can be from 1 to 1,000 ppm, preferably from 10 to 750 ppm, more preferably from 50 to 500 ppm, most preferably from 100 to 250 ppm, for example, 150, 175, 200 or 225 ppm. In another modality, the rates of use of 1-MCP are about 0.1 to 50 g per hectare of culture grown under irrigation.

    The following examples further illustrate some aspects of the invention, but are not intended to limit its scope. Where not otherwise specified throughout this specification and claims, percentages are by weight (% w / w).
    Example 1 - Effect of 1-MCP on wheat plants under tension ml of the mixture are added per bag with a pipette.
    25 kernels of wheat from the ARINA variety were sown in a plastic bag (bag) with a paper absorbent, watered and grown under optimal conditions in an air-conditioned chamber for 8 days. On day 8, 1-MCP in the form of a molecularly encapsulated α-cyclodextrin powder was applied at a rate of 200 ppm to the water in the bag. After application, the plants were no longer watered, but placed in an environment heated to 26 ° C. After 5 days, without watering, the differences between treated and untreated were assessed visually (figure 1). Treated plants show a higher tolerance to drought than control plants when grown under drought stress (5 days without watering).
