What weed pollen causes the most common fall allergies

Ragweed is, by far, the leading cause of allergy in the autumn months. The ragweed season can vary but tends to start in August and continue correct through to November in some areas.

Around 75 percent of people with spring allergies will develop a ragweed allergy in drop. The plant thrives in areas where there are cool nights and warm days. While ragweed can beautiful much be found in every part of the U.S.

(including Hawaii and Alaska), it is most prevalent in the Midwest and on the East Coast where the peak season runs until early- to mid-September.

As with other grass allergies, the pollen is highest during the morning hours, on windy days, and shortly after a rainstorm. Ragweed can grow just about everywhere but can proliferate in fields, along the side of the road, or in vacant lots.

What are drop allergy symptoms?

Fall allergy symptoms are not much diverse than what you would expect at other times of year. Most people refer to their symptoms as hay fever, while doctors refer to it as seasonal allergic rhinitis.

Whatever you call it, symptoms include:

  1. Worsening eczema
  2. Itchy, watery, and stinging eyes.
  3. Upset stomach
  4. Coughing and wheezing, potentially leading to asthma for sufferers.
  5. Scratchy throats and excessive saliva
  6. Life-threatening asthma attacks in extreme cases.

Treatment and Defense against Ragweed Allergies

The best defense is a excellent offense.

With proper weed control, you can get rid of the ragweed around your home.

Remove any ragweed plants you discover around your property and own your yard treated to kill weeds and control the pollen release near your home.

Also do not wait to contact your allergy specialist to plan your allergy treatments. Allergy immunotherapy treatment involves istering little doses of an allergen to get your body used to it and induce long-term tolerance of the allergen.

How to Avoid Drop Allergies

Avoiding drop allergies is often easier said than done.

After every, with work, family, and a social life, you can't shut yourself in with antihistamines and a box of tissues.

Instead, you own to be strategic in how you approach allergy season by taking certain, basic precautions. Among them:

  1. Vacuum floors, surfaces, and furniture regularly, ideally with a pet-friendly vacuum cleaner designed to suck up dust, dander, mites, and other tiny particles.
  2. Check the local pollen and mold counts on the daily weather report.
  3. Use a HEPA filter and/or air humidifier to hold airborne pollen levels low.
  4. Keep your windows and doors shut at home, especially on days when the pollen count is high.
  5. Wear a NIOSH-rated 95 filter mask when mowing the lawn or doing outdoor work.
  6. Shut the car windows and air vents when driving.
  7. Take a shower and change your clothes after you’ve worked or played outdoors.

Finally, if you own a history of drop allergy symptoms, speak with your doctor or allergist about daily medications you can take to lessen the impact of the season.

    What weed pollen causes the most common drop allergies

    "Common Seasonal Allergy Triggers." Arlington Heights, Illinois; updated December 28, 2017.

Seasonal allergies, including drop allergies, affect more than 35 million Americans and cost the U.S. economy more than $7 billion in lost productivity.

Fall Allergies: Understanding Allergens

"Inhalant allergens are substances that can trigger allergy symptoms when inhaled by sensitive people," explains Bruce Gordon, MD, an ear, nose, and throat allergy specialist at Cape Cod Hospital in Hyannis, Mass., and an instructor at Harvard University in Cambridge, Mass.

"Inhalant allergens are divided into two types on the basis of their persistence: perennial and seasonal,” Dr.

Gordon says. “Perennial allergens are present throughout the year, with little variation. Seasonal allergens own distinct periods of time in which they are present in the environment in large quantities."

Gordon says that plants typically pollinate in three seasons: “These seasons vary in length as a function of the growing season. In the spring, trees pollinate. In the summer months, especially in early summer, grasses pollinate.

Finally, in tardy summer and into drop, weeds pollinate."

Fall Allergies: Ragweed

One of the main contributors to drop allergies is the ragweed plant. A single plant can produce one billion pollen grains per season. Ragweed grows abundantly throughout the South, North, and Midwest, and its lightweight pollen grains can travel up to 400 miles in the wind.

"Ragweed pollen has a extremely distinct season from tardy summer to mid-fall,” says Gordon. “East of the Rocky Mountains, ragweed is the predominant cause of outdoor drop allergy symptoms." Ragweed can be found growing in vacant lots, along the road, and in open fields.

"In areas with colder temperatures, the first frost generally occurs at about the time ragweed pollination ends. In Southern regions, ragweed may pollinate through the winter," notes Gordon.

Fall Allergies: Other Weeds

In various parts of the country, goldenrod, curly dock, lamb’s quarters, pigweed, sheep sorrel, and sagebrush can every cause drop allergies. "Goldenrod blooms at the same time that ragweed does, but it is insect-pollinated [as opposed to wind-pollinated] and is not a significant allergen for most individuals,” Gordon says.

“The bright goldenrod flower, however, does alert everyone that the more inconspicuous ragweed is also blooming."

Fall Allergies: Molds

Outdoor molds are another cause of drop allergies. They first appear in early spring, but thrive until the first frost.

They are common in soil, compost piles, and in the leaves that cover the ground during the drop. "In temperate climates, mold spores form a distinct drop season in mid to tardy drop, after ragweed season is over. Mold spores are common airborne allergens. They are light, extremely little, and easily inhaled into the lungs. Spores rise high in the atmosphere during the warming of the day, falling back to the ground with the cool of evening," says Gordon.

Fall Allergies: Protecting Yourself

If you own drop allergies, you should be additional cautious on windy days and in the morning.

"Wind-pollinated plants such as ragweed own specialized male flowers that produce huge amounts of buoyant pollen, easily released into the wind. Pollen is most often released in the mornings,” Gordon says, cautioning that people who are allergic to pollen own strong sensitivities in the morning.

Here are some other precautions you can take:

  1. Have decaying leaves removed from your yard and gutters.
  2. Use a face mask when you are exterior, especially between 5 and 10 a.m. and on windy days.
  3. Dry your clothes inside in the dryer instead of hanging clothes outside.
  4. Remove pollen from your skin and hair by showering frequently.
  5. If you rake leaves in the drop, wear a face mask.
  6. Keep your windows closed and turn on the air conditioner.
  7. When you first turn on your car air conditioner, leave your windows open and avoid breathing the air for several minutes until mold spores can disperse.

Fall Allergies: Don’t Suffer in Silence

If your symptoms of sneezing, runny nose, or itchy and watery eyes get worse in the drop, you probably own an outdoor drop allergy.

Eighty percent of people with seasonal allergies complain about these symptoms as well as problems with sleeping, being tired, having poor concentration, and decreased productivity at school or work.

But treatment is available. “Many [people] can be helped with modern medical treatments, if they would only complain to their doctors and get tested to detect possible allergies," urges Gordon.

All you need to know about pollen allergy.

What is pollen allergy?

Pollen is one of the most common triggers of seasonal allergies.

Numerous people know pollen allergy as “hay fever.” Experts generally refer to pollen allergy as “seasonal allergic rhinitis.” Pollen from trees, grasses, and weeds are the most common cause of allergies and especially ragweed is a main cause of weed allergies.

What are the symptoms?

For people with allergies, pollen is an allergen that causes an allergic reaction. Their immune system treats the pollen as an invader and responds by mobilizing to attack by producing large amounts of antibody. This allergic reaction can cause the following symptoms: sneezing, runny nose, red watery eyes, itchy throat and eyes, wheezing, fatigue, and irritability.

Pollen isn’t just produced by flowering plants.

The plants that are most plain looking such as weeds and grasses, they tend to cause more allergy symptoms than the large, beautiful flowers.

Why? That’s because the grasses and weeds own light, dry pollen that goes in the air. Whereas large flowers and trees which fertilized by insects, such as roses and cheery trees, they own heavy, sticky pollen, which only gets transmitted by insects, bees and butterflies. It’s not so much in the air.

Find out which type of pollen you are allergic to.

Even if you see a high pollen count, it doesn’t necessarily mean that you will be affected. There are numerous types of pollen — from diverse kinds of trees, from grass and from a variety of weeds.

The best way to discover out which type of pollen trigger your allergy is to through testing, an allergist can assist you identify which pollens bring on your symptoms.

Pollen allergies can be prevalent through every the seasons.

Pollens spread by the wind. Spring is not the only allergy season, numerous plants pollinate year circular. Where you live will determine the time and duration of your pollen season. Moving to another climate to avoid allergies is unfortunately not successful because allergens are virtually everywhere.

If you’re allergic to certain kinds of pollen, there are some food you might desire to avoid.

Some fruits and vegetables own proteins that are similar to the aspect of pollen that causes allergies.

They could trigger oral allergy syndrome, which could cause itchiness, numbness or tingling in your mouth:

  1. Grass pollen allergy: Avoid celery, melons, oranges, peaches, tomatoes.
  2. Ragweed pollen allergy: Avoid bananas, cucumbers, melons, sunflower seeds, zucchinis.
  3. Birch tree pollen allergy: Avoid apples, almonds, carrots, celery, cherries, hazelnuts, kiwis, peaches, pears, plums.

Pollen counts are lowest in the evening.

The quantity of pollen in the air varies from day to day, as well as throughout the day, pay attention to the pollen count in your living area before you plan your outdoor activities might assist.

On an average day, pollen counts rise during the morning, peak about midday, and then gradually drop. So the lowest time is generally before dawn and in the tardy afternoon to early evening. Besides, weather factor also plays an significant roll. Wind blows up pollen into the air, keeping counts high, while rain dramatically lowers airborne pollen.

Most people in Florida glance forward to autumn with its pumpkin spice lattes, mild sun and cooler air. But if you’re one of the estimated 40 million drop allergy sufferers in the U.S., this time of year can be extremely unpleasant.

It doesn’t own to be that way, though…

With the proper precautions and correct allergy treatments, you can enjoy every that autumn has to offer.

While most people often associate allergies with spring and the pollen produced by flowering plants, drop can be the worst season to deal with allergies.

As the weather here in Jacksonville cools, plants tend to release more pollen and the moist, cool air leads to increased mold growth on leaves and other surfaces.

Combined, these factors can trigger severe allergic reactions.

Drop Pollen Allergies

Weed pollen is the main cause of hay fever (allergic rhinitis) during the tardy summer and early drop months.

What weed pollen causes the most common drop allergies

Depending on where you live in North America, the main allergen concerns include:

  1. Burning bush
  2. Ragweed
  3. Cocklebur
  4. Pigweed
  5. Lamb’s-quarters
  6. Russian thistle
  7. Sagebrush
  8. Tumbleweed
  9. Mugwort

While the severity of an allergy season can vary by seasonal climate, there can be days (and even times of day) when the allergy risk is high.

This includes windy and warm days when pollen counts can soar. By contrast, rainy days can significantly reduce the pollen count (only to give rise to higher counts when the grasses dry out).

Along with grasses and weeds, mold is a major cause of drop allergies. This is especially true in areas where large piles of damp leaves are allowed to sit and rot.


This is probably the number-one cause of drop allergies.

Ragweed thrives every over the Central and Eastern United States, from far north to deep south. If you own hay fever symptoms in the drop, it’s almost certainly due to ragweed.

Though ragweed starts to release it’s pollen with cool evenings and warm, humid days in August, it can continue well final into September through October.

Approximately 75% of people who are own spring plant allergies are also allergic to ragweed.

Additionally, ragweed pollen gets around. The amazing thing is that even if ragweed pollen isn’t common where you live, wind blown ragweed allergens can travel for hundreds of miles!

Common Ragweed

It can grow as tall as five feet, with leaves that are arranged alternately and leaf blades that are endless and own deep divisions in them.

The flowers are not “showy” and result in little, green or yellow spikes.

Giant Ragweed

Fittingly named, giant ragweed can grow up to 15 feet high, with stems that own multiple branches and hairy leaves that grow opposite of each other (until you get high up the weed). The leaves are sandpaper-rough and rounded.

Both types of ragweed release their pollen in tardy summer and continue to saturate the air through the first frost (which doesn’t happen often here in North Florida).

One ragweed plant is capable of producing more than one billion grains of pollen per season.

What are the most common Florida drop allergens?

Here in Florida, most drop allergies are caused by either weed pollen or mold spores.

Because our weather provides for longer growing seasons, grass and mold pollen allergies tend to extend well into November.

Here are the most common culprits we own to contend with:
