Wild Oat


Wheat, a critical staple crop worldwide, faces several threats that can significantly reduce its yield. One such menace is the Wild Oat (Avena fatua), a weed that can drastically affect wheat production.

Its robust growth often allows it to outcompete wheat, particularly in resource-limited conditions. Wild Oat competes with wheat for water, nutrients, and light. The competition for resources can lead to smaller, less robust wheat plants, resulting in smaller grain heads and reduced grain quality.

Wild Oat can host several diseases and pests, such as the cereal cyst nematode and the wheat curl mite, which can inflict significant damage to wheat crops.

How to Identify Wild Oat

Wild Oat, a grassy weed, often blends with wheat during the early growth stages, making identification challenging. However, certain key indicators can help distinguish this weed.

Wild Oat plants typically tower over wheat with a more robust stem. Their leaves are broader and exhibit a bluish-green hue, contrasting with the yellow-green wheat leaves. The seed heads of Wild Oat are loose and open, bearing large, plump seeds covered in fine, hair-like structures.

Unlike the uniform growth of wheat, Wild Oat tends to grow in patches. If you spot patches of taller plants with a different color, it could indicate a Wild Oat infestation.

Geographic Impact of Wild Oat

Wild Oat thrives in a wide range of climates and soils, predominantly in the temperate regions of North America, Europe, and Australia.

Timing of Wild Oat Emergence

Wild Oat usually germinates in the fall or early spring and continues to grow throughout the season.

How to Manage Wild Oat in Wheat

Wild Oat’s ability to blend in with wheat crops, robust growth, and potential to host diseases make it a challenging weed to manage. However, by learning to identify Wild Oat and understanding its impacts, farmers can take steps to manage this weed and safeguard their wheat crops.


For managing Wild Oat in wheat, consider two products: Zidua® SC herbicide and GoldSky® herbicide.

Zidua® SC herbicide, containing Pyroxasulfone, is specifically labeled for use with wheat to control Wild Oat. It is available from FBN®. Zidua® alone may only suppress Wild Oat. Therefore, apply Zidua in conjunction with a Group 1 or Group 2 herbicide, like GoldSky®, for most effective control.

GoldSky® herbicide contains Florasulam, Pyroxsulam, and Fluroxypyr, 1-methylheptyl ester. It is also labeled for use with wheat for controlling Wild Oat and can be purchased from FBN.

Both of these products can help effectively manage Wild Oat in your wheat fields. The application rates for these products are:


In Canada, Wild Oat is becoming a challenging weed because it can cut back the yield and cause downgrading of wheat due to high dockage. Group 1 and Group 2 herbicide-resistant Wild Oat is becoming more common as a result of overusing these herbicides or cutting back the rates.

FBN offers a variety of products that may help farmers control Wild Oat in their fields throughout the year. These products are as follows:

Spring Pre-Seed Burn-Off and Post-Harvest/Fall Application

In Crop

FBN Clodinafop helps control Wild Oat in spring wheat and durum. It is tank mixable with a lot of other options for broadleaf herbicides like FBN CapTTain and FBN Sterling. It’s a Group 1 herbicide, so consider different modes of action while applying herbicides throughout the year.


Using Smoke® 540 Glyphosate during pre-harvest will help farms lower the germination of Wild Oat in the field, reducing the population of Wild Oat for the next year. However, this option should not be used if the grower is planning on keeping the wheat seed for seeding the following year.
