Re: Nemacur needs our help...Nematicide under attack by EPA?
Hello Hosta buffs,
I have been trying to procure Nemacur for the better
part of 3 months. I made this decision after reading research published
in the AHS Journal, Vol 30, No 1; "Control of Foliar Nemotodes on Hosta"
by James R. Baker and Ronald K. Jones (NCSU, Raleigh).
The results show Nemacur 3 (2.5 gallons) as being very effective (the
most effective of all products tested). Nemacur 10G (EPA # 3125-237) was
labeled for use in Iowa as a retricted use nematicde, for Turf and Ornamental
use. However, Bayer ceased manufacturing that product and has replaced
it with the Nemacur 15G product. Unfortunately, they neglected to get it
labeled for Iowa ($250.00 fee with very low demand, so little marketing
justification) and now there appears to be an active push on by the EPA
to get Nemacur banned. (Vydate/Oxamyl are all but gone, too).
As a Cholinesterase Inhibitor, the chemical is fairly toxic, but like
cranberries and Saccharin, you're probably not supposed to eat a whole
train-car full in one sitting. Application can be done only by those with
a restricted use license, and the EPA is concerned that people may be getting
hurt needlessly. (Applicators that aren't paying attention?)
More timely information is available at <a href="http://www.bayerfqpa.com/news_flash.html">Bayer
Agricultural</a> but if you know ANYTHING about how to assist Bayer
in this effort, please let me know. I understand that a person can make
comments to the EPA, but am unfamiliar with the process.
Last year was the first year ever that I actually
had any nematode infestation, so this year I wanted to take preventive
and curative action early. And, I received plants from three other
vendors that untimately developed the symptoms, so I don't believe
I am alone in needing to find a solution.
I don't want to dig every Hosta out of the ground,
soak it in 120F water for 10 minutes, throw away the soil around the plant,
and then replant it. I have about 400 in my personal collection at present,
not to mention 3,000 or so in pots. (However, I have only seen suspected
infestation in 2 pots--it's rather rare to have nematodes infect plants
in containers, or so I understand.)
I have contacted an ISU extension horticulturalist,
and expect to do more on this issue soon. If you can help in any way, now
is the time! We don't have many effective nematicides available to
