As a wheat farmer, you want your crops to be healthy and productive. However, sometimes things can go wrong and your plants may start exhibiting symptoms of yellowing or browning. One common cause of this problem is herbicide application.
There are a number of herbicides that can cause yellowing of wheat. These include glyphosate, chlorsulfuron, and imazethapyr, among others. These herbicides interfere with the plant’s ability to produce chlorophyll, a vital pigment in photosynthesis that gives plant tissue its green color. When this happens, the plant’s leaves may turn yellow, brown, or even black, which can indicate a problem.
One possible explanation for yellowing after herbicide application is that the herbicide is not compatible with the specific crop or variety of wheat. Some herbicides may have different levels of compatibility with different crops or may work better on certain varieties of wheat. Additionally, the age of the plant can also play a role in the herbicide’s effectiveness. For example, some herbicides work better on younger plants, while others may work better on older plants.
Another possible cause of yellowing after herbicide application is the dosage. Applying too much or too little herbicide can cause problems. Generally, the dosage of herbicide is determined by the size of the plant, the growth stage, and the type of herbicide used. It is important to follow label instructions in this regard.
So, what can you do if your wheat is yellowing after herbicide application? First, you should carefully check the herbicide label to see if it is compatible with your specific crop and variety. You should also double-check the application rate and the timing of the application. If these factors seem fine, you may want to consider using a different herbicide or contacting a professional agronomist for advice.
Ultimately, preventing plant yellowing after herbicide application requires careful planning and attention to detail. By selecting the right herbicide, using the correct dosage and timing, and carefully measuring application rates, you can help ensure your wheat crop stays healthy and productive.
