The Sclerotinia
Initiative is now in its seventh year and researchers
recently reported that progress in genetic tolerance is being
made in most susceptible crops.
Wild sunflower is a potential gold mine for resistant genes.
Researchers report head and stalk rot immunity in a number of
wild sunflower species which have been in testing for six years.
Literally hundreds of lines are now ready for seed production
increase and field testing.
Commercial sunflower hybrids tested under heavy disease pressure
are showing an increased tolerance. Fungicide research is also
showing promise for controlling head rot. Some of the fungicides
are experimental and remain unregistered.
The Sclerotinia
Initiative is a federally funded competitive research
program which includes soybeans, canola, edible beans,
peas/lentils and sunflower. |
