UGA Extension fruit pathologist says use lime sulfur on blueberries to manage Exobasidium disease

By Clint Thompson, University of Georgia

The key to managing Exobasidium leaf and fruit spot disease in blueberries, which makes the fruit unmarketable, is one application of lime sulfur approximately two weeks prior to bud break, according to Jonathan Oliver, University of Georgia Cooperative Extension fruit pathologist.

Exobasidium disease causes spots on the leaves and fruit, decreases the fruit’s size and, because of the fruit’s immaturity, gives it a bitter taste. The leaf spots eventually turn velvety and white and lead to early defoliation, and the spotted fruit is not fit for sale. Continue reading

Elemental sulfur linked to breathing problems

Elemental sulfur, the most heavily-used pesticide in California, may harm the respiratory health of children living near farms that use the pesticide, according to new research led by UC Berkeley.

In a study of children in the agricultural community of Salinas Valley, California, researchers found significant associations between elemental sulfur use and poorer respiratory health. The study linked reduced lung function, more asthma-related symptoms and higher asthma medication use in children living about a half-mile or less from recent elemental sulfur applications compared to unexposed children.
