MSMA can be effective in killing grass burrs, also known as field sandbur. MSMA stands for monosodium methanearsonate, and it is a post-emergent herbicide that is commonly used to control a variety of grassy and broadleaf weeds in lawns and other turf areas.
When it comes to field sandbur control, it is important to apply MSMA when the weed is still young and actively growing. This is because MSMA works best on young, actively growing weeds. As the field sandbur matures and develops a stronger root system, it becomes more difficult to achieve effective control with MSMA.
To use MSMA for field sandbur control, it is recommended to follow the instructions provided by the manufacturer. Typically, MSMA is mixed with water and applied as a spray directly onto the weed foliage. It is important to ensure thorough coverage of the weed to maximize its effectiveness.
In my personal experience, I have found MSMA to be quite effective in controlling field sandbur when applied at the right time. The key is to catch the weed early before it has a chance to develop and spread its burs. Once the burs have formed, it becomes much more challenging to control the weed and prevent it from spreading.
It is worth noting that MSMA is a selective herbicide, meaning it targets and kills certain types of weeds while leaving desirable grasses unharmed when used as directed. However, it is important to check the label or consult with a professional to ensure that MSMA is safe to use on your specific type of grass or turf.
In addition to MSMA, another herbicide that can be effective in controlling field sandbur is DSMA, which stands for disodium methanearsonate. DSMA is similar to MSMA and can be used as an alternative for post-emergent control of field sandbur.
MSMA and DSMA can be effective options for post-emergent control of field sandbur. It is important to apply these herbicides when the weed is young and actively growing for the best results. However, as the weed matures, achieving effective control becomes more difficult. Always follow the instructions provided by the manufacturer and consider consulting with a professional for specific recommendations for your lawn or turf.
