We claim.

1. The method of protecting plants against infection by fungi by applying DFMO to the plants.

2. The method of Claim 1 where pinto bean plants are given protection from infection by uredospores of the bean rust fungus.

3. The method of Claim 1 where tomato plants are given protection from infection by Verticillium wilt, a fungas disease of tomato.

4. The method of Claim 1 where wheat is given protection from infection by Leaf Rust fungus.

5. The method of Claim 1 where wheat is given protection from infection by Stem Rust fungus.

6. The method of Claim 1 where wheat is given protection from infection by Powdery Mildew fungus.

7. The method of Claim 1 where Tendergreen bean plants are given protection from infection by Powdery Mildew fungus.

8. The method of Claim 1 where MacIntosh apple leaves are given protection from infection by Powdery Mildew fungus.

9. The method of Claim 1 where Ogle oats are given protection from infection by stem rust fungus.

10. The method of Claim 1 where corn plants are given projection from infection by Corn Rust fungus.

11. The method of Claim 1 where the DFMO being sprayed onto the plants is in solution in 0.01% wetting agent dilutions as low as 0.01 mM and has given protection for the plants measured at 50% or more against the wheat leaf rust disease of plants.

12. The method of Claim 1 where the DFMO is sprayed at dilutiions of 1.0 mM in a 0.01% wetting agent onto the plants up to three days after the plants have been infected by a rust fungus and complete protection against a rust fungus is obtained.

13. The method of Claim 1 where the DFMO may be applied to a portion of each of the plants to be protected and the remaining parts of each plant, including new leaves thereof, are also protected.

14« The method of Claim 1 where the DFMO may be applied to the plants, or parts thereof, and each plant, including new leaves thereof, will be protected for a period of time determined by the concentration of the DFMO in the wetting agent.

15. A new use for a known chemical compound known as DFMO wherein said chemical compound is dissolved in a wetting agent and sprayed on a plant as a fungicide.

16. A new fungicide comprising a chemical compound known as DFMO dissolved in a wetting agent, said DFMO dissolved in a wetting agent being useful for spraying plants to protect them from fungal pathogens which cause disease of that plant.

17. The method of protecting plants against infection by obligate and/or biotrophic parasitic organisms by applying DFMO to the plants.
