|Contribution||Transmitted rust from barberry bush to rye by inoculation of spores.|
|Notes||Niels Pedersen Scholer. Tranmission from one host species to another was already known to farmers and accepted by some scientists (e.g. Banks in 1805). It was the basis for the 1755 Barberry Law of Massachusetts -- the first law passed for the control of a plant disease. Publication date not available.|
