Abstract
Non-phytotoxic roots coating compositions comprising a polymer, VAM propagules, and a fungicide that selectively inhibits pathogenic fungi are provided. Also provided are methods of coating plant roots with the aforesaid composition and plants comprising roots coated with a polymer containing VAM propagules and a fungicide. In an alternative approach, the roots are first rolled in a dried polymer composition and then dipped in a suspension of VAM propagules, or attached to a film which is a dried polymer containing a spore suspension.
Claims14
A method for forming a growth promoting polymer coating on the roots of a plant which method comprises rolling the roots of the plant in a powder of dry hydrophilic non-phytotoxic polymer;
- removing the roots from the powder, and dipping the powder-coated roots into a aqueous suspension of VAM propagules at a concentration effective to promote infection.
A flexible polymeric film for coating the roots of plants to introduce VAM infection which film comprises dried film of a non-phytotoxic, hydrophilic, flexible film-forming polymer and VAM propagules at a concentration effective to introduce said infection.
