A SEED SURFACE COMPOSITION COMPRISING A DPP PIGMENT AND A SEED TREATED WITH SAID COMPOSITION

TECHNICAL FIELD

The present invention relates to a seed surface composition comprising a compound according to formula (I) wherein Ri and R2 are independently of one another hydrogen, C1-C4 alkyl, halogenated C1-C4 alkyl, C1-C4 acetyl; and R3 and R4 are independently of one another phenyl, C1-C5 alkylphenyl, C1-C5 alkoxyphenyl, halogenated phenyl, cyanophenyl, biphenyl, halogenated biphenyl, pyridyl, C1-C5 alkylpyridyl, C1-C5 alkoxypyridyl, halogenated pyridyl or naphthyl. The present invention further relates to a seed treated with a composition comprising a compound according to formula (I). The present invention furthermore relates to a process for producing the seed surface composition. The present invention furthermore relates the use of a compound according to formula (I) in a seed surface composition.

INTRODUCTION

It has been known to apply various active ingredients directly to the surface of seeds for protecting the seeds from disease, fungi and insects, etc., and for the purpose of providing the seed with growth regulators and nutrients. Seeds treated on the surface with active ingredients have proven to be quite successful in terms of germination rates, etc. Seeds treated on the surface for the above-mentioned purposes are not intended for the use as food or feed. To avoid that these seeds get into the food chain, these seeds have to be marked by a color. In many cases, e.g. cereal seeds or seeds for maize or other food and feed crops are marked using a red colorant. For this purpose widely used red pigments are based on diazo-chemistry, e.g. C.L PR 112, PR 48:2, PR 53:1 (D&C Red No. 9), PR 57:1 (D&C Red No. 6) or PR 57:2 (D&C Red No. 7). Diazo pigments have disadvantages regarding ecological effects due to the reductive cleavage of the azo bonds or hydrolysis of anilido bonds, which would produce aromatic amines, many of which have been under global scrutiny due to a suspicion for genotoxicity or carcinogenicity. They are regulated in several countries and particularly for applications with food contact. So for example, commonly used C.L PR 112 could possibly release 2,4,5-trichloraniline, which has to be considered as toxic in contact with skin, toxic if inhaled and is very toxic to aquatic life. Other typical diazo colorants used may potentially degrade to sulfonated aromatic amines that are not genotoxic, but are water soluble. Accordingly, there remains the problem of providing a seed surface composition and treated seeds, which do not contain diazo compounds, but are highly versatile with regard to the amount of the used color and obtained color depth. In particular, there remains the problem of providing a seed surface composition and treated seeds, which do not have disadvantages regarding ecological effects and are highly versatile with regard to the amount of the compound according to formula (I) used while having the required color depth.

Reference Examples: Determination methods a) L*a*b* C* Determination

The term L * (lightness) used herein means the lightness in the L*a*b* color space (also referred to as CIELAB) specified by the Commission Internationale de I'Eclairage, wherein a* and b* are the chromaticity coordinates. The L* value is measured at an observation angle of 25°. According to the CIELAB system, L* = 100 means the lightest value (white), L*= 0 means the darkest value (black). Generally, a L* value refers to an opaque coating.

The term C* (chrome) used herein means the chroma in the L*C*h color space (also referred to as CIELAB) specified by the Commission Internationale de I'Eclairage, wherein L* is the same lightness as in the L*a*b* color space and h is the hue angle.

Solid colors (CIELAB color measurement) were measured using Datacolor 650 d8 integrating sphere spectrophotometer with D65 illuminant and 10° observer. Data handling via BASF Col- orCare software. b) Color quality scale

The color quality scale has been determined visually. The value 1 refers to a color that is barely viewable. The value 2 refers to a color that sticks less than 50% to the surface of the seed. The value 3 refers to a color that sticks more than 50% but irregularly to the surface of the seed. The value 4 refers to an almost completely colored surface of the seed. The value 5 refers to completely and perfectly colored surface of the seed. Examples
