Compositions comprising a pesticide and an oil which exhibit reduced chemical degradation of the pesticide upon storage when applied to seeds

We publish herein compositions comprising a pesticide and an oil as defined herein; a method for preparing a composition as defined herein, which comprises the step of contacting at least

one pesticide and at least one oil; and the use of an oil as defined herein for reducing the chemical degradation of a pesticide upon storage when applied to seeds. The preferred embodiments of the compositions mentioned herein below have to be understood as being preferred either independently from each other or in combination with one another.

Oils can be used to improve application properties of aqueous seed treatment products on seeds (dust-off, seed flowability). The loss of active ingredients in seed treatment formulations and on the treated seeds has been investigated. It was noticed, that when pesticide compositions applied on seeds contained an oil with a certain degree of unsaturation, i.e. an oil which contains unsaturated carbon-carbon bonds, chemical changes of the active ingredient

The term "oil" herein refers to any neutral, nonpolar chemical substance that is a liquid with a pourpoint above 10°C according to DIN 51597 and measured following procedure ISO 3016:1994 and has a solubility in water which is less than 10 g/L, more preferably less than 5 g/L, most preferably less than 1 g/L; for example natural or naturally derived oils produced by plants, animals, and other organisms; or derivatives like fatty acids, fatty acid esters as well as

alkoxylated fatty esters, fatty alcohols, fatty alcohol ethers incl. alkoxylated fatty alcohol ethers. Furthermore mineral oils such as, for example, crude oil, or petroleum, and its refined components, collectively termed petrochemicals; or synthetic oils. The term "synthetic oil" herein refers to oils that are artificially made (synthesized). Synthetic oils can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be

method (Journal of AOAC Int. 1994, 77(3), 674-6). The degree of unsaturation lies in the number of carbon-carbon double bonds in a chemical sample. These double bonds react with iodine molecules and allow for a quantitative measurement of the degree of unsaturation. The higher the iodine number, the more carbon-carbon double bonds are present in the oil.

In a preferred embodiment said described compositions comprise oils, which are further

occured on treated seeds upon storage. The primary factor for the loss of acive ingredient in the formulation is chemical degradation. It was found that the active ingredient remains stable on seeds, which are treated with a composition comprising an oil as defined or preferably defined herein, while at the same time maintaining the application properties that are required when treating seeds. 20
