Controlling Weeds in Wheat Crops: Two Months After Sowing
Wheat is one of the most important staple crops around the world. But, just like any other crop, it faces many challenges, chief among them being controlling the growth of weeds that can compete with it for sunlight, moisture, and nutrients. As a wheat farmer, one of the critical measures to ensure a successful crop is to control the growth of weeds. Here is an overview of how to control weeds in your wheat crop two months after sowing.
Why weed control is important two months after sowing
Typically, in the first two months, wheat seedlings grow at a slower pace, and their root systems are relatively shallow. The crop’s slow growth makes it susceptible to the competition posed by rapidly growing weeds. As such, controlling weeds at this stage is critical to ensure the wheat crop can grow and develop efficiently without being hindered by weeds.
Integrated Weed Management Approaches for Wheat Crops
Integrated weed management is the use of various weed control methods to ensure a crop is free from weeds. Here are five main weed management approaches for wheat crops, two months after sowing:
1. Cultural control methods
Cultural control methods for weed management focus on adjusting the environment where the wheat crop is grown to make it unfavorable for weed growth. Examples of cultural control methods used are crop rotation, shallow tillage, crop density, and crop residue management.
2. Mechanical control methods
Mechanical weed control involves the use of physical techniques, such as hoeing and hand weeding, to uproot or destroy weeds. This approach is most effective in small-scale wheat crop farming, as it can be labor-intensive for large-scale farmers.
3. Chemical control methods
Using herbicides is the most popular approach to weed control among wheat crop farmers. The herbicides can be applied in two ways: pre-emergence herbicide- applied before weed seeds haven’t germinated or post-emergence herbicide – applied after weed seeds have begun to emerge. The right herbicide to use depends on the species of weed present on the farm. We recommend farmers use herbicides with residual efficacy to protect their crops from future weed growth.
4. Biological control methods
Biological control methods are most often used to control perennial weeds that cannot be eliminated by the other methods mentioned. Examples of biological control methods include using pathogens and insects that feed on weeds to kill them.
5. Genetic control methods
The transgenic approach is still under research for weed control in wheat. However, a new study in 2021 from the University of Sheffield has discovered a genetic method for control of brome grasses, a common weed in wheat farming that is usually resistant to herbicides.
In conclusion, weed control management two months after sowing wheat is crucial to ensure optimum wheat yield. The best approach is to use integrated weed management techniques. By combining the likes of cultural control or herbicides, biological, and genetic control methods, farmers can successfully control weed growth, ensuring a healthy and productive crop.
