BATON ROUGE, La. (BRPROUD) -- If you've been sneezing and feeling itchiness lately, it's likely because of fall allergies from ragweed pollen. The LSU AgCenter said there are two culprits for seasonal allergies during this time of the year -- goldenrod and ragweed. Experts said the allergy symptoms are most likely because of ragweed. Ragweed has green flowers and is highly branched from the bottom upward, according to LSU AgCenter Horticulturist Heather Kirk-Ballard. Goldenrod is described to be similar to sunflowers with bright yellow blooms. "It is possible, although rare, to be allergic to goldenrod. Your seasonal sniffles are most likely caused by ragweed," said Kirk-Ballard. The Asthma and Allergy Foundation of America said 50 million people in the U.S. have symptoms from ragweed pollen in the late summer and early fall. Allergies can make you miserable. Here’s how to track pollen levels near you "Some studies have shown that climate change has made the ragweed pollen season longer and more intense. This is a major cause of increased pollen," the foundation said. Some symptoms include runny and stuffy nose, postnatal drip, sneezing, itchy nose, eyes, ears and mouth, red and watery eyes and disturbed sleep. To control ragweed, Kirk-Ballard suggests hand pulling or mowing them before the plant begins to make pollen or using non-selective herbicides like glyphosate.
