SEED COATINGS COMPOSITIONS AND METHODS FOR USE
A seed or seedling is coated with a least one rosin-based resin and optionally, a second binder, which is for instance a biodegradable polymer. The seed coating composition is characterized by a dust value, as measured using a Heubach dustmeter device according to Euroseeds reference method “Assessment of free floating dust and abrasion particles of treated seeds as a parameter of the quality of treated seeds”, which is lower by at least 30% as compared to an analogous binder-free composition that does not contain the rosin-based resin.
1 - 12 . (canceled)
13 . A coated seed composition comprising:
at least one seed; and
at least one layer coating all or part of the seed, the layer comprising at least one rosin-based resin.
14 . The composition of claim 13 , wherein the at least one rosin-based resin has a Ring and Ball softening point ranging from about 10° C. to about 150° C.
15 . The composition of claim 13 comprising a dust value, as measured using a Heubach dustmeter device according to the Euroseeds reference method, which is lower by at least 30% as compared to an analogous binder-free composition that does not contain the rosin-based resin.
16 . The composition of claim 13 , wherein the rosin-based resin does not comprise polymers within the meaning of Article 3(5) of Regulation (EC) No 1907/2006.
17 . The composition according to claim 13 , further comprising a second binder.
18 . The composition of claim 13 further comprising at least one active ingredient.
19 . A method for preparing a coated seed composition having dust suppression benefits comprising the step of contacting at least a portion of at least one seed with at least one layer comprising at least one rosin-based resin,
wherein the coated seed composition comprises a dust value, as measured using a Heubach dustmeter device according to the Euroseeds reference method, which is lower by at least 30% as compared to an analogous binder-free composition that does not contain the rosin-based resin.
20 . The method of claim 19 , characterized by a dust value, as measured using a Heubach dustmeter device according to the Euroseeds reference method, which is lower by at least 50% as compared to an analogous binder-free composition that does not contain the rosin-based resin.
21 . The method of claim 19 , further comprising a second binder.
22 . A method of providing dust suppression, the method comprising using at least one rosin-based resin as defined in claim 13 as a binder for a seed coating application.
23 . A seed coating composition comprising at least one rosin-based resin as defined in claim 13 .
24 . The seed coating composition of claim 23 , further comprising a second binder.
