How to Manage Mustard Weeds in Wheat

Research indicates that wheat yield can decrease by up to 50% in fields heavily infested with mustard.

Mustard competes with wheat for essential nutrients, water, and space, often gaining the upper hand due to its early germination. Furthermore, it can induce physiological stress in wheat plants through allelopathy, a process in which a plant releases chemicals that inhibit the growth of neighboring plants. Mustard plants release glucosinolates, which break down into compounds that can hinder wheat germination and growth.

How to Identify Mustard Weeds 

Mustard, belonging to the Brassicaceae family, often intrudes wheat fields. Its bright yellow flowers, blooming from May to September, serve as a telltale sign. The plant can tower up to 1.5 meters, with deeply lobed, alternating leaves. Its seeds, small and round, range in color from reddish-brown to black.

Geographic Impact of Mustard Weeds 

Mustard thrives in temperate regions worldwide, including North America, Europe, and parts of Asia. It prefers well-drained, fertile soils, making wheat fields an ideal environment.

Timing of Mustard Weeds  

As a winter annual weed, mustard seeds germinate in the fall, surviving the winter as a rosette. Come spring, the rosette bolts into a flowering plant, setting seeds. This lifecycle makes mustard easy to spot early in the wheat growing season.

How to Manage Mustard Weeds in Wheat

To maintain crop health and yield, managing mustard in wheat fields is vital. The first step is identification, followed by effective control measures such as crop rotation, use of certified seeds, and targeted herbicide application. 

For mustard management in wheat, Alligare 2,4-D Amine and Fancy are recommended herbicides. Both are labeled for use with wheat and specifically control mustard. They are available from FBN®. 

The typical application rate for Alligare 2,4-D Amine is 24 oz/ac (range: 16–32 oz/ac). For Fancy, please check the label for application rates. 

Always adhere to the recommended application rates and guidelines provided on the product labels for effective and safe use.
