I apologize for the "blind-siding" if you were not aware of the rules and conventions of the forums.

My general philosophy is that a person cannot be blind-sided if they don't have a blind side - that is, if they know what they are doing. If it seems innocent from lack of opportunity to learn, I'll offer some gentle education. Likewise, if someone is innocently spreading misinformation. But if a person appears to have not bothered to read the directions, or has ignored offers of correct information, that's a willful blind side, and I'll challenge it.

There's an old story in Missouri where my daughter lives. A farmer is selling a mule and tells a potential buyer how great a worker it is and how well it follows directions. The interested buyer asks for a demonstration. The farmer picks up a club and hits the mule on the head. He tells the puzzled buyer "First you have to get its attention ".

The inappropriate promotional activity was tolerable until it touched on a very sore point - the ProMax.

My career was with a government agency identifying pests on plants in their growing sites. Part of the year I was assigned to reviewing preliminary pesticide labels submitted for registration. I had to verify that the labels met EPA registration requirements. The issue of over-promotion of inadequate control products was always a prime irritation. I had to try to educate growers against the promotional hype.

I'd appreciate hearing what you know and have learned about using this product.

Was this product recommended to you for controlling root knot nematodes on daylilies? By whom? What research did they provide to support any claim that it would control the root knot nemas on your daylily plants?

>>You can apply it year round, but we apply it late summer/early fall, after all the plants have flowered.

The ProMax label indicates the product should be used on 15-20 day intervals throughout the growing season. Who recommended that 2 applications at the timing you used would be efficacious / adequate to control root knot nemas on daylilies?

The product requires being incorporated into the soil after or during application. What method of incorporation do you use?

>We find it works well,

What data have you collected to demonstrate to your satisfaction that it "works well"?

Does the S Carolina Dept of Agriculture require nematode testing? Which kinds do they test for?

Random WWW pictures of root knot nematodes on root systems other than daylilies are not relevant. The appearance on daylily roots is different. Do you have any images from roots of your daylilies?

Are you treating all 3 acres of daylilies? Are you using the lower recommended rate (1 gallon per acre) or higher rate (2 gallon per acre)?

I fully understand that controlling root knot nematodes is a daunting challenge especially, as you noted, with a perennial crop. Between those and now daylily rust, a warm climate is about the least desirable location for a daylily nursery. My sympathies on that, actually

After rust arrived, lifelong Floridians David Kirchhoff and Mort Morss took the drastic step of moving their entire business from Florida to Kentucky to escape the need for pesticides. I understood.
