Definitions
- composition comprising DMPP and phosphonate
- the invention relates to a composition
- a composition comprising (i) a specific pyrazole or an agriculturally acceptable salt thereof; (ii) a phosphonic acid or an agriculturally acceptable salt thereof; (iii) optionally, one or more carboxylic acids, agriculturally acceptable salts or anhydrides thereof; and (iv) optionally, one or more glycols.
- the compositions according to the invention provide improved solubility of salts of pyrazoles such as 3,4 DMPP in aqueous solution. The solutions are stabilized against crystallization by lowering the crystallization point.
- Nitrification is an aerobic process performed by small groups of autotrophic bacteria and archaea. It is an important step in the nitrogen cycle in soil, wherein ammonia is biologically oxidized to nitrite, followed by the oxidation of the nitrite to nitrate. Nitrification of nitrogen containing fertilizers reduces their efficiency, as the contained nitrogen is oxidized and no longer available for take up by crops. Therefore, nitrogen containing fertilizers commonly comprise nitrification inhibitors to reduce nitrification, when the fertilizer is applied to the soil.
- Negative side effects of nitrogen-containing fertilizers such as the production of nitrate ions to be washed out into the subterranean water and/or the production of nitrous fumes, in particular N Z O which is/are further identified to enhance the climate change, are of growing public concern. Both effects are based on metabolic activities of soil bacteria, which - in several steps - turn urea and other nitrogencontaining fertilizers into N 2 O and/or nitrate ions.
- nitrification inhibitors The key enzymes involved in nitrification can effectively be inhibited by nitrification inhibitors.
- the enzymes involved in this step can be inhibited by known nitrification inhibitors such as pyrazole derivatives. 3,4- dimethylpyrazole (3,4 DMP) and its phosphate salt 3,4-dimethylpyrazole-phosphate (3,4 DMPP) are the most widely discussed and used ones.
- pyrazole derivatives 3,4- dimethylpyrazole (3,4 DMP) and its phosphate salt 3,4-dimethylpyrazole-phosphate (3,4 DMPP) are the most widely discussed and used ones.
- Commercially available fertilizer additives have relatively low concentrations of the active substance and suffer from low stability, especially at lower temperatures. If a nitrification inhibitor

- maleic acid anhydride as acidic component provided a significant decrease of the crystallization temperature and for some time a stable supersaturated solution was formed.
- maleic acid anhydride should readily hydrolyze to maleic acid.
- maleic acid was chosen as the best available organic acid for the protonation of the pyrazole.
- Example 5 [0137] Aqueous mixtures of 3,4 DMPP, maleic acid (added in form of maleic acid anhydride) and etidronic acid showed a further decrease of the crystallization temperature towards low refrigerator temperature like 1-2°C. It was observed that this effect is proportional to the amount of added etidronic acid until a threshold is reached.
- the possible amount of etidronic acid is restricted to 40 wt.-% of a 60 wt.-% active solution (such as Cublen® KT600/with 60% active).
- a 60 wt.-% active solution such as Cublen® KT600/with 60% active.
- a solution of 3,4 DMPP having a somewhat lower concentration of about 18 wt.-% active was less difficult to obtain/stabilize.
- Such solutions can be prepared by half-stoichiometric replacement of the maleic acid by acetic acid and a reduction of the etidronic acid addition down to 12 wt.-%:
- compositions of 100 mL aliquots fix in 30 wt.-% 3,4 DMPP, 10 wt.-% propylene glycol, and 2 wt.-% PEG 200 were prepared with various amounts of maleic acid anhydride (MSA), etidronic acid, 2-phosphono-l,2,4-butanetricarboxylic acid (PBTC) and/or acetic acid, respectively.
- MSA maleic acid anhydride
- PBTC 2-phosphono-l,2,4-butanetricarboxylic acid
- acetic acid acetic acid
- a phosphonic acid etidronic acid or PBTC
- PBTC phosphonic acid

Abstract
L'invention concerne une composition comprenant (i) un pyrazole spécifique ou un sel acceptable en agriculture de celui-ci ; (ii) un acide phosphonique ou un sel acceptable en agriculture de celui-ci ; (iii) facultativement, un ou plusieurs acides carboxyliques, des sels ou des anhydrides acceptables en agriculture de ceux-ci ; et (iv) facultativement, un ou plusieurs glycols. Par rapport aux compositions classiques, les compositions selon l'invention fournissent une solubilité améliorée de sels de pyrazoles tels que 3,4 DMPP dans une solution aqueuse. Les solutions sont stabilisées contre la cristallisation par abaissement du point de cristallisation.
