Applying products with dicamba (at a rate of 1 lb ai/A) or Crossbow® (2 to 4 qt/A) are effective at controlling spiny pigweed. Crossbow® can also be applied as a spot treatment (1-1.5% v/v). Spiny pigweed, also known as spiny amaranth, is one of the most common weeds seen in pastures.

When you get rid of prostrate pigweed before it goes to seed, you reduce its ability to come back in future years. If you wish to kill prostrate pigweed with chemical controls, look for weed killers that contain the chemicals dicamba, glufosinate-ammonium, or glyphosate.

Apply post herbicide when pigweed is small (<4 inches tall).

1. Better to include herbicide with residual activity in addition to dicamba, glufosinate, or 2,4-D (Atrazine, Callisto (or other mesotrione product), metolachlor, acetochlor or Zidua/Anthem)
2. Avoid glyphosate or ALS inhibitors.

Pigweed seeds are easily spread through cultivation and on agricultural implements as well as via animals, where they are still viable after being digested. In addition to being spread by seed, broken stem fragments can re-establish, forming new plants and aiding its spread.

This plant has high severity poison characteristics. Pigweed is a multi-stemmed summer annual in the Amaranth family. Considered a weed, it can be found growing in wastelands, prairies, fallow fields, farm lots, gravelly areas, and cultivated fields. Its invasiveness causes yield loss in many vegetable row crops.

Pigweed or carelessweed is very common in areas where cattle congregate. Cattle will readily eat the young plants, but avoid the older plants unless forced to eat them. Redroot pigweed is more toxic than spiny-root pigweed, but is less common. Pigweed can accumulate nitrates, so sudden death is the most common outcome.

“Pigweed” is a common name for a few different plants, including lambsquarters, but the particular pigweed I’m writing about is the one whose genus is Amaranthus, also known as “amaranth.” There are around 60 species of amaranth — all have varying degrees of good-to-eatness.

Pigweed allergies, also known as Lamb’s Quarters, is a weed that produces heavy pollen and can induce hayfever, asthma, and conjunctivitis symptoms. Pigweed pollen is most common during the summer months. It can be found in nurseries, crops, roadsides, pastures, and other rural areas.

Common pigweed allergy symptoms can be similar to many other pollen allergies and may include: Sneezing. Nasal congestion. Runny nose.

Identify ragweeds and pigweeds by their leaves. Common ragweed has fern-like leaves, while giant ragweed has distinctive, large, three- or five-lobed leaves. The upper leaves of pigweeds are lance-shaped and are up to 7 inches long. Lower leaves are more egg- or diamond-shaped.

Cottonwood tree allergy symptoms can be similar to many other pollen allergies and may include: 4,6. Sneezing. Nasal congestion. Runny nose.

Non-sedating antihistamines, nasal rinses, nasal steroids and showering before bed can help lessen symptoms, but if symptoms remain unresolved it’s a good idea to see the doctor, Demain said.

Infused into oil, the resin is known to help soothe swollen arthritic joints and sore muscles. Resin was used to waterproof boxes and baskets. The bark was made into buckets for storing and carrying food. The leaves, buds and bark of cottonwood were used to lower fevers and reduce inflammation and pain.
