Weed seeds toxic to horses

Weed seeds are most commonly a problem as a contaminant in grains.

As little as 0.25 percent of a horse’s bodyweight in corn cockle seeds can be toxic.

0.3 to 0.7 percent of a horse’s bodyweight in eastern black nightshade berries can be toxic and may cause death.

Cleaning or blowing oats can help prevent toxicity.

In this article we will cover corn cockle seeds, mustard seeds and Eastern black nightshade berries.

Identifying

Weed seeds come in many shapes, colors and textures.

Corn cockle and mustard seeds are round or oval in shape and dark brown or blackish in color.

Eastern black nightshade berries are small and round. They turn from green to dark purple or black when ripe.

Where are they found?

These weeds seeds appear throughout the U.S..

You can find these weed seeds in cultivated fields, gardens and ditches. Corn cockle and mustard commonly appear with small grain crops, like oat. You may find Eastern black nightshade in soybeans and sometimes hay.

Toxicity

The seeds relative to their plant, contain the highest level of toxic chemical. Seeds are usually a problem when they occur as a contaminant in grain (e.g. oats or soybeans).

As little as 0.25 percent of a horse’s bodyweight in corn cockle seed can be toxic.

0.3 to 0.7 percent of a horse’s bodyweight in eastern black nightshade berries can be toxic and may cause death.

A toxic amount of mustard seed is unknown.

Signs of illness

Remove the seed source. Horses will normally need fluid therapy with electrolytes. You may need to consider antidiarrhea treatment.

Control

Weeds seeds are common in “bin run,” unblown or unscreened oats. Blowing or screening oats separates the smaller weed seeds and other foreign matter from the oats. Commercial grain sellers and feed stores commonly blow or clean oats. If you grow your own oats, make sure they are blown or cleaned before feeding or seeding.

Other information

Some weed seeds can live dormant in the soil for 20 years or more years. This causes weed problems in pastures and hay fields. Most seeds grow in the first few years after they fall from the plant. Regardless, weed control efforts should focus on reducing or eliminating weed seed production.

What Makes A Plant A Weed? Characteristics of Weeds and What They Are

There are approximately 250,000 species of plants throughout the world and it is estimated that about 8,000 or so of these species can be considered a weed. Per the Weed Science Society of America (WSSA), there are about 312 common weeds that can be found in the U.S. Take a look at the common weeds and their weed identification information.

It is interesting to look through the list to see what plants are considered weeds, but can also be considered desired plants, such as birch, spruce and yews.

What Makes A Plant A Weed?

The definition of a weed is a plant growing where it is not wanted. It can also include plants that were not intentionally sown in a specific location or plants that are more competitive or interfere with the activity of people. Another way to think of it is that the undesirable qualities of the plant are more problematic than the good qualities – based on the opinion of those who are viewing the plant.

It is our decision to make plants weeds based on several criteria or characteristics that we feel may be detrimental to us personally, to others around us, to our pets or livestock or to the economic impact weeds may have to crops or other agricultural endeavors.

Characteristics of Weeds

Weeds have several characteristics that are considered negative and as mentioned previously interfere. Below are some characteristics of weeds:

• Plants that produce an abundant of seed
• Plants that have an extensive root system or other vegetative structures that spread above or below the ground
• Plants that grow quickly
• Plants that can cause bodily harm to humans or animals
• Plants that can harbor diseases or insects that affect desired plants
• Plants that can produce chemicals that are toxic to surrounding plants
• Plants that can reduce crop growth or inhibit harvest

Weeds are plants first before they are determined to be weeds. As plants, they do have attributes that can be considered beneficial to the environment. They can help keep soil in place, provide a place for wildlife to live and to feed, and can be aesthetically pleasing. As they die, they can turn into beneficial organic matter. In some cases, they can also have nutritional benefits. In the case of companies like Spring-Green, weeds can provide business and employment opportunities.

As it is written, beauty is in the eye of the beholder. Not all plants are weeds, but all weeds can have negative impacts on ways that food is produced for humans and livestock, to human health and to the overall environment. These negative impacts leads to the need to control many weeds. Remember, you can always count on Spring-Green to take care of your lawn this season and eliminate weeds.
