Citrus canker, a serious disease of citrus, was recently found on trees in East Baton Rouge and Livingston parishes, according to LSU AgCenter plant doctor Raj Singh. Citrus canker is a highly contagious bacterial disease that was first detected around 1914 in Louisiana and declared eradicated by 1940. The disease is known to cause defoliation, premature fruit drop, blemished fruit and tree decline. Severely infected trees ultimately may stop producing fruit. If you believe your citrus trees have citrus canker, contact the U.S. Department of Agriculture at 225-298-5410 or the LDAF Horticulture and Quarantine Division at 225-952-8100.

The emerald ash borer, a severe insect pest of ash trees, was confirmed in Webster Parish in February 2015, making Louisiana the 25th state to confirm the presence of this beetle. In 2014, the LDAF started a "Don’t Move Firewood" campaign which is geared toward educating people about the risks of transporting pests to other locations where some can do harm. It is best to purchase firewood not more than 10 miles from where it will be burned.
