Area golf courses apply Sevin (especially during the spring) to temporarily knock down the earthworm population to reduce bumpy turf. We use it to discourage mole activity, cuz Sevin is toxic to worms, yet is a fairly safe product (used in flea/tick shampoos for pets) . Anybody else use Sevin or similar products to knock down earthworms/nightcrawler population?

I am by no means an "organic" lawn guy but I kinda like seeing earthworm activity. They help loosen the soil and that to me is beneficial. While we do have moles here. They are generally not a major problem. I have used Sevin in the past for armyworm control. I've never sprayed it for the sole purpose of knocking back earthworm populations.My State paperwork states that I am licensed to treat for insects and diseases feeding on or damaging the lawn. Earthworms don't fit in that niche.

I understand where you're coming from. Sevin is labeled for and effective on over 100 insects & mites for turf, trees, shrubs, vines, ground covers, vegetables, etc, etc. If your are licensed to treat turf only....here's some turf insects that Sevin is labeled for: ants, cutworms, sod webworms, army worms, aphids, grubworms, grasshoppers. There's a lot more. Sevin dust is commonly used on foods that humans eat (tomatoes, cucumbers, grapes, and a whole lot more).

If Cleary 3336 is applied at the root disease rate and watered in as per the label. There is usually a drastic decrease in earthworm activity. Try googleing "thiophanate methyl & earthworms" I know this chemical is actually labeled for this use in England. Unless you are trying to keep a putting green or bowling green, should not be a big deal if there are castings. Earthworms are active near the surface if the soil is heavy, poorly aerated and overwatered. Instead of using Sevin or 3336, I educate clients about proper watering practices and soil management. They probably need to cut down on their watering and core aerate+topdress the lawn.

earthworms are benefical insects and rose bushes are beautiful shrubs, but if a rose bush was growing in a cornfield it would treated as a weed(undesirable growth). have you ever seen what worms can do to a putting green

I am guilty of treating a lawn for "cough, cough" both summer patch and billbug damage 4 oz 3336 + 6 oz Sevin SL watered in immediately.. It is not a routine application for me. However, I can see doing it if it bothers the client that there are ping-pong ball sized castings all over the lawn and they are not overwatering. I will otherwise leave it alone.

Golf course superintendants have a very unstable job as it is and if the greens commitee wants the worms dead Damn right they will kill them so thier children which as you may not realize are higher on the food chain can eat.

My point is....is that g.c. supers, as well as the golfers themselves should have a whole heck of alot more to think and /or worry about...than a few greens or tees that may have a larger number of "over-exuberant" :cool2:worms on them.

I would suspect that over 90% or so of the people that regularly play golf can understand the concept that any given golf course is never going to be "perfect".
Indeed, playing around sometimes unknown and unforeseen imperfections, such as "worm mounds", should make most golfers even better players for the experience !!
