Citrus disease has been found in Louisiana

BATON ROUGE, La. (AP) - Sweet orange scab, a citrus disease
recently discovered in Texas, has made its way to Louisiana.
tstU AgCenter plant pathologist Don Ferrin says the disease was
confirmed Aug. 20 on samples from a residential lime tree in New
Ferrin says fruits are only susceptible to the disease for the
first six to eight weeks of their development. He says that's when
they need to be protected and the only fungicides readily available
for homeowners are copper-based fungicides.
Sweet orange scab occurs primarily on sweet oranges, tangerines
and satsumas, but it also can occur on other types of citrus trees.
The scab presents little problem, but because it's mostly
cosmetic, Ferrin says it affects the ability to sell infected fruit
for the fresh market.
