Abstract :

---

Surfactants are often used in seed coatings to homogenise seed size and to protect seeds from injuries. Nonionic soil surfactant formulations based on ethylene oxide-propylene oxide (EO/PO) block copolymers are commonly used to increase root-zone water reserves in water repellent soils. Therefore the potential toxicity or beneficial of one Alkyl polyglycoside – EO/PO Block Copolymer Surfactant on onion (Allium fistulosum L.), Radish (Raphanus raphanistrum subsp. Sativus) and lettuce (Lactuca sativa) seeds was evaluated. This non-ionic surfactant was tested at 0, 0.125, 0.25, 0.5, 1.0, 1.5 g of product/Kg of seed with comparison of uncoated seeds. Seed germination was measured. In general, the highest surfactant concentration decreased seed germination. 1.0 g of surfactant/Kg of seed was the recommended concentration for onion, radish and lettuce seed coating.
