Mowing is a common method used to terminate cereal rye cover crops. However, many farmers and gardeners are unsure if mowing will effectively kill the rye or if other methods are necessary. In general, the effectiveness of mowing depends on the growth stage of the cereal rye and the timing of the mowing.
Will Mowing Cereal Rye Kill It?
According to Penn State Extension, mowing cereal rye is most effective when done at the flowering stage. Mowing too early can result in the plant re-growing or standing back up readily.
On the other hand, mowing too late can result in the rye producing viable seed, which can lead to weed problems in subsequent crops. Therefore, it is crucial to time the mowing correctly to ensure effective termination of the cereal rye cover crop.
It’s important to remember that mowing effectiveness can differ depending on the variety of cereal rye and environmental conditions.
For instance, when the soil is too wet, the mowing may not terminate the rye. Additionally, somecies may be more resistant to mowing than others. When deciding whether to mow your cereal rye cover crop, these factors should be taken into account.
Understanding Cereal Rye
Life Cycle of Cereal Rye
Cereal rye is a cool-season grass that is often used as a cover crop. It is a hardy plant that grows well in a variety of soil types and can tolerate cold temperatures. Cereal rye can be planted in the fall and will grow throughout the winter. In the spring, it will begin to flower and produce seed heads. If left unmanaged, cereal rye will continue to grow and produce seeds until it is terminated.
Importance of Cereal Rye
Cereal rye is an important cover crop because it can provide a number of benefits to farmers and the environment. When used as a cover crop, cereal rye can help to prevent soil erosion, improve soil health, and suppress weeds. It can also help to reduce nutrient runoff and improve water quality.
One of the key questions that farmers have about cereal rye is whether or not mowing it will kill the plant. The answer to this question depends on a number of factors, including the growth stage of the plant and the method of mowing.
Research has shown that mowing cereal rye at the flowering stage is the most effective way to terminate the plant. If mowed too early, the plant may regrow or stand back up readily. On the other hand, if mowed too late, the plant may have already produced seeds and will not be effectively terminated.
Cereal rye can also be terminated using other methods such as roller-crimping or tillage. However, the effectiveness of these methods will depend on a number of factors including the growth stage of the plant and the equipment used.
Mowing and Its Impact
Effect of Mowing on Cereal Rye
Mowing is a common method used to terminate a cereal rye cover crop. However, it is important to note that mowing alone may not be enough to kill the rye.
According to a blog post from the University of Minnesota Extension, mowing cereal rye at the wrong time can actually stimulate new growth. This can result in a more difficult termination process later on.
Mowing can also have varying effects on the rye depending on the height of the rye at the time of mowing. An article from Farm Progress suggests that mowing rye when it is less than 6 inches tall may not be effective in terminating the crop. On the other hand, mowing rye when it is taller than 12 inches can result in the rye being too difficult to terminate.

Ideal Time to Mow
For optimal results when terminating cereal rye, it is best to mow when the rye is between 6 and 12 inches tall. Consider the weather conditions, however, as wet conditions can make for difficult mowing and may prevent proper termination.
Ensure that the rye is mowed at least 10-14 days prior to planting the next crop; this will provide ample time for the rye to decompose and avoid competition with the following crop. Through careful timing and weather observation, mowing can easily terminate cereal rye.
Factors Influencing Mowing Effectiveness
Mowing height is an important factor to consider when mowing cereal rye. According to a study by the University of Wisconsin, mowing at a height of 4 to 6 inches is effective in terminating cereal rye.
However, mowing too low can result in incomplete termination and regrowth. It is important to note that the optimal mowing height may vary depending on the growth stage of the cereal rye and the equipment used for mowing.
Weather conditions can also affect the effectiveness of mowing on cereal rye termination. Mowing during dry weather conditions can result in incomplete termination and regrowth, as the cereal rye may be more resilient to mowing stress. On the other hand, mowing during wet weather conditions can result in soil compaction and damage to the cereal rye stems, leading to better termination. However, mowing during wet conditions can also result in soil erosion and damage to the mowing equipment.
Mowing cereal rye can be an effective method of termination, but it is important to consider factors such as mowing height and weather conditions to ensure complete termination and prevent regrowth. Proper equipment and timing can also contribute to the effectiveness of mowing.
Alternative Methods to Kill Cereal Rye
When it comes to terminating cereal rye cover crops, mowing is a common method used by farmers. However, it may not be effective in killing the crop, especially if it is not done at the right time. Fortunately, there are alternative methods available for killing cereal rye cover crops.
Chemical control involves using herbicides to kill the cereal rye. Glyphosate is a commonly used herbicide for terminating cereal rye. It is effective in killing the crop, but it is important to use the right amount.
Using too little glyphosate will not kill the crop, while using too much can lead to environmental damage. Other herbicides that can be used for terminating cereal rye include paraquat and glufosinate. These herbicides are non-selective contact herbicides that can be used in cool springs.
Cultural control involves using non-chemical methods to kill the cereal rye. Roller-crimping is a popular cultural control method that involves using a machine to crimp the cereal rye stems, killing the crop and creating a mulch bed.
This method is effective, but it requires specialized equipment and may not be suitable for all farmers. Grazing is another cultural control method that involves allowing livestock to graze on the cereal rye, killing the crop. This method can be effective, but it requires careful management to ensure that the livestock do not overgraze the crop.
In conclusion, mowing may not be an effective method for terminating cereal rye cover crops. Farmers can use alternative methods such as chemical and cultural control to kill the crop. It is important to choose the right method based on the specific needs of the farm and the crop.
