When the temperatures drop in the winter time, homeowners may feel that they will soon see the end of their weed troubles such as crabgrass. However, the seeds of these weeds are very much alive but are in hiding, using all the nutrients of your soil to hibernate and rise up in the Springtime to ugly up your yard. When crabgrass emerges, they can be extremely difficult to control.

That’s why it would be wise to stop crabgrass before it emerges onto your turf with a pre-emergent active ingredient like prodiamine. Solutions Pest & Lawn has some great herbicide products which contain the active ingredient prodiamine and we regularly suggest this product to our customers who want to control weeds such as crabgrass. On this page we will share with you background info about prodiamine, it’s mode of action and benefits. You can also access this page to shop our entire line of prodiamine-based products.

What is Prodiamine?

Prodiamine is an active ingredient used in pre-emergent herbicides. Prodiamone works as a pre-emergent control of grasses and broadleaf weeds. By using it once a year, pre-emergents help control weeds.

Prodiamine is registered for commercial use  to control weeds in nurseries, landscaping, turf farms, Christmas tree farms, golf courses, and more.  Prodiamine can also be safely used on certain types of desirable grasses without harming them, such as Bermudagrass, Fescue, St. Augustine and common turf grasses.

Prodiamine was first registered in 1992 to the EPA for use in non-crop areas such as rights-of-way, conifer and hardwood seedling nurseries, established perennial and wildflower plantings, established turf sites, residential and institutional lawns, commercial sod farms, golf courses, railways, and landscape ornamentals. Prodiamine is manufactured by Syngenta Crop Protection, Inc. and sold under the trade name Barricade and other generic post-patent brands.

How Does Prodiamine Work? Prodiamine acts through inhibition of root growth by blocking plant cell division steps needed for chromosome separation and cell wall formation. Prodiamine is a pre-emergent herbicide so essentially it acts as a sort of birth control for the target weed, preventing the weed seed from growing.

While we don’t want to discount the solid effects of Prodiamine and how it has successfully controlled plenty of different weeds of various types of grass and turfs, it is important to note that with prodiamine or any pre-emergent herbicide, that the results may not be 100 percent. Depending on the resilience and stubbornness of some hard-to-control weeds, there may still be some weeds that pop up during growing season meaning that some post-emergent treatment may have to still be conducted.
