If you’re looking for a herbicide that will effectively control pre and post-emergent crabgrass, you may be wondering what the major differences are between pendimethalin and prodiamine. While both pendimethalin vs prodiamine products are effective at controlling crabgrass, there are some key differences that you should be aware of before making your purchase.
One of the biggest differences between pendimethalin and prodiamine is the application method. Pendimethalin must be applied before crabgrass seeds have germinated, whereas prodiamine can be applied either before or after crabgrass has germinated. This makes pendimethalin a better choice if you’re looking to prevent crabgrass from growing in the first place, while prodiamine is a better choice for controlling existing crabgrass growth.
Active Ingredient Concentration
Another significant difference between these two products is the active ingredient concentration. Pendimethalin contains 3.8% dimethylamine salt of pendimethalin, while prodiamine contains 65.6% di-n-propyl Isocyanate (DNPI). This means that pendimethalin is less concentrated than prodiamine, which means that you’ll need to use more of it to achieve the same level of efficacy.
Duration of Activity
It’s important to note that pendimethalin and prodiamine differ in terms of duration of activity. Pendimethalin provides up to four weeks of crabgrass control, while prodiamine provides up to eight weeks of control. So, if you’re looking for a longer-lasting solution, prodiamine is the better choice
When it comes to environmental impact, pendimethalin and prodiamine are fairly similar. Both products are considered slightly toxic to bees and other pollinators, and they should not be applied to areas where these creatures are active. However, pendimethalin is considered slightly more toxic than prodiamine, so you’ll need to take extra care to avoid harming bees and other pollinators if you choose to use this product.
Also, it’s important to consider efficacy when choosing between pendimethalin and prodiamine. Both products are fairly effective at controlling crabgrass, but pendimethalin is typically considered to be slightly more effective than prodiamine.
The Overall Cost
The cost is another important factor to consider when choosing between pendimethalin and prodiamine. Pendimethalin is typically more expensive than prodiamine, so if cost is a concern, prodiamine may be the better choice.
Which is Right for You?
The best herbicide for you will depend on your specific needs and preferences. If you’re looking for a preventative solution, pendimethalin is a good choice. If you’re looking for a longer-lasting solution, prodiamine is a better choice. And if you’re concerned about environmental impact, prodiamine is the better option.
So, what’s the bottom line? Both pendimethalin and prodiamine are effective at controlling crabgrass, but there are some important differences that you should be aware of before making your purchase. If you’re looking for a product that can be applied either before or after crabgrass has germinated, go with prodiamine. On the other hand, if you’re looking for a longer-lasting solution, pendimethalin is the way to go. Whichever product you choose, make sure to read and follow all label instructions carefully.
