Description

Composition for use in agriculture The present invention relates to a composition comprising (a) an organic acid and (b) one or more compounds of Formula (I), , as well as compositions further comprising one or more fatty acid or derivative thereof. The present composition is suitable for maintaining the applicability of biological plant protection products based on fatty acids or derivatives thereof. The present invention also relates to methods of producing such composition and methods of applying it. Although fatty acids or fatty acid derivatives provide excellent means in protecting plants from insect pests or plant pathogens, there is still the need to even improve those means in order to address the ever increasing environmental and economic requirements imposed on modern-day crop protection agents and compositions. This includes, for example, improvement to the spectrum of action, safety profile, selectivity, application rate, formation of residues, and favorable preparation ability, and development of new compositions to deal with potential problems, like resistances. In order to be applied to the plant, plant protection compositions based on fatty acids or salts thereof need to be diluted with water. Depending on the water hardiness and salt load, issues may arise relating to spray application which may result in a reduced applicability of the plant protection composition, visible residues and/or blocked sprayer filters and nozzles because of flocculation and/or precipitation problems. Accordingly, it was an object of the present invention to provide means for overcoming the above obstacles. This has at least in part been achieved by the present invention as described below. Summary of the invention As a result, in a first aspect, the present invention relates to a water conditioner comprising (a) an organic acid and b) one or more compounds of Formula (I) Formula (I) where R1 is branched or linear alkyl with 3-17 C-atoms; n is between 0 and 20, preferably between 0 and 15, more preferably between 0 and 12; R2 is Hydrogen or S(O2)O- R3; and R3 is H+, Li+, Na+, K+, [NH4]+, [H3O]+, [NO]+ or N[CH3]4+- Preferably, R3 is Na+, K+ , more preferably R3 is Na+. The present invention also relates to a composition comprising (a) one or more fatty acids or derivatives thereof selected from unsaturated and saturated C12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing; and (b) the water conditioner according to the invention. In another aspect, the present invention relates to a method for producing a plant protection formulation comprising (a) Providing one or more fatty acids or derivatives thereof selected from unsaturated and saturated C12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing; (b) Adding a water conditioner comprising an organic acid and one or more compounds according to Formula (I) Formula (I) where R1 is branched or linear alkyl with 3-17 C-atoms; n is between 0 and 20, preferred between 0 and 15, more preferred between 0 and 12 R2 is Hydrogen, or S(O2)O- R3+ R3 is H+, or Li+, or Na+, or K+; [NH4]+, [H3O]+, [NO]+ or N[CH3]4+’ preferably Na+ or K+; more preferably Na+ to the water-based liquid to be used for dilution; and (c) Mixing the components according to (a) and (b) to form an emulsion, microemulsion or solution; and optionally (cl) Adding said emulsion, microemulsion or solution into a water-based liquid. In a different aspect, the present invention relates to a method for maintaining the insecticidal, fungicidal and/or herbicidal efficacy of one or more fatty acids or derivatives thereof selected from unsaturated and saturated C12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing to be diluted in hard water, comprising (a) Providing one or more fatty acids or derivatives thereof selected from unsaturated and saturated C12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing; (b) Adding a water conditioner according to the invention to the water-based liquid, preferably water to be used for dilution; and (c) Mixing the components according to (a) and (b) to form an emulsion, microemulsion or a solution. In yet another aspect, the present invention relates to a method for reducing overall damage of plants and plant parts as well as losses in harvested fruits or vegetables caused by plant pests comprising the step of applying the composition according to the invention comprising fatty acids or derivatives thereof as described herein to a plant or seed or a locus where said plant or seed is intended to be grown. The invention also relates to a kit-of-parts comprising (a) one or more fatty acids or derivatives thereof selected from unsaturated and saturated C12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing and (b) a water conditioner comprising an organic acid and one or more compounds according to Formula (I) Formula (I) wher
