Image Number D3174-1 Rust response in three seedling sunflower plants 12 days after inoculation with the most virulent rust race identified so far in the United States. HA 89 (an oil-type sunflower) and CONFSCLB1 (a confection sunflower) are highly susceptible, showing typical symptoms of rust in the infected leaves, whereas HA-R6 (also a confection sunflower) is highly resistant and shows no symptoms.
