Pre-emergent are herbicides designed to kill weed seeds BEFORE they sprout. They are usually granular and are applied to lawns and flower beds in the spring, but they persist for three months – that means prolonged time for human exposure.
Below we have gathered important information about some typical active ingredients and their effects:
Prodiamine – carcinogen, neurotoxicity
Pendimethalin – extremely toxic to fish and aquatic organisms
Isoxaben – possible carcinogen, kidney/liver damage, toxic to birds
Oxyfluorfen – possible carcinogen, reproductive, birth and development effects, kidney/liver damage, skin irritant, toxic to fish and aquatic organisms
Oryzalin – kidney/liver damage, skin irritant, birth and developmental effects, toxic to fish and aquatic organisms
Trifluralin – extremely toxic to fish and aquatic organisms
Also, since the active ingredient is usually only 1% ... what are the 99% "other ingredients" ? They are often a blend of equally toxic ingredients that amplify the deadly effectiveness, which means they are even more toxic for you too.
Safe alternative? Although corn-gluten is often recommended as an organic pre-emergent for lawns, it is expensive, and timing is too critical to be effective, so we don’t recommend it. The PRFCT nature-based approach to weed control is to outcompete weeds in lawns. Overseed lawns in the fall or early spring before weeds germinate. In shrub and flower beds plant many small plants close together, leaving little to no space or sun for weeds. More plants is always a better option for filling space than bark mulches from far away.
Read Between the Lines of Your Pesticide Program
It’s the time of year when landscape contracts are headed your way and we think it’s important you know how to read between the lines. This sample is a landscape contract that was sent out this month in NY. If your landscaper follows a standard pesticide program, chances are yours will be similar.
Many states mandate that any chemical applied to your lawn is disclosed in your contract. This includes Minimum Risk Pesticides, sometimes called 25(b)’s, which Perfect Earth Project would say are okay to use. An example would be a biopesticide which is a naturally occurring substance or a microorganism that is applied to control pests.
But when it comes to synthetic lawn and landscape chemicals, do not turn a blind eye. The more you know, the better choices you can make to seek alternatives and keep yourself and your loved ones safe.
Don’t fire your landscaper, talk to them. Find out if any of the “targets” are even issues in your lawn. We can help you talk to your landscaper about kicking the toxic synthetic chemical habit.
Just this one contract would mean exposure to probable carcinogens, and substances linked to neurotoxicity, endocrine disruption, neuromuscular effects, birth and reproductive effects, kidney and liver damage and canine lymphoma. They are toxic to pollinators, birds, fish and aquatic organisms and pollute our aquifers.
If your lawn can be just as beautiful without synthetic chemicals, why would you expose yourself to this?
