Definitions

  • the present invention relates to coating compositions including an organic component for applying to seeds of oilseed plant from which roots and shoots are capable of growing, uses of coating compositions on oilseed plant seeds, methods of producing such coating compositions and oilseed plant seed coated with such coating compositions.
  • the invention relates to coating compositions that comprise an organic material that provides protection from environmental stresses to oilseed plant seed.
  • Young oilseed plants grown from oilseed plant seed are vulnerable to abiotic and environmental stresses, particularly in growing habitats that have low rainfall and/or sub- optimal soil quality. Losses due to sub-optimal soil quality are typically realised in the growth of young plants lacking plant vigour in which the plants do not become well established, such as where the rooting systems do not develop and in circumstances where essential elements in the soil are not readily available. Agronomic losses due to young oilseed plants not being well established remain unacceptably high on soils which are for example mineral deficient despite the employment of conventional inorganic oilseed plant seed coatings that typically include essential elements for establishing young seedlings.
  • Such conventional coatings are typically applied in the form of wet slurries to oilseed plant seeds. Once applied, the coatings are typically dried on the seeds and this drying may cause further abiotic stresses, which in turn may have deleterious consequences on the viability of young plants grown therefrom. Additionally, such conventionally applied coatings may not be applied to oilseed plant seeds evenly, and as a consequence, such coatings tend to be susceptible to chipping and/or flaking. Furthermore, the degree of coating uniformity of such conventionally applied coatings typically is not optimal, with a percentage of seeds of any one batch receiving little or no coating depending on the coating method being deployed.
  • oilseed treatment and “oilseed coating” are used interchangeably for the compositions of the invention and their uses to treat oilseed plant seeds, by any of the specific methods described in the prior art that provide an improvement, typically an enhancement, of seedling vigour.
  • the commonly used ingredients in oilseed plant seed treatment compositions include antidotes and safeners; fertilisers, micronutrients and inoculants; bioregulators of natural or synthetic origin which are either hormones or interfere in hormone metabolism and do not influence plant nutrition; and/or bioregulators which interfere with plant growth by enhancing nutrient uptake.
