Coating Seeds with Polyvinyl Resins

TL;DRAbstract

SummaryTwo resins were tried and both showed low toxicity to turnip, carrot and cabbage seeds, when tested immediately after treatment, but reduced the germination of onion seed. Compared with ‘Polycell’ treatment, resin treatment did not reduce germination consistently after 18 months’ storage. Vinamul 8450 was viscous and difficult to handle, but Vinamul 8330 was as effective as the standard coating material, 2% w/v Polycell, for incorporating the fungicide Rovral, and did not reduce the effectiveness of the fungicide. The resin also dried rapidly, thus preventing premature germination and enabling the seed to be stored.
