NPP is not labeled for either of these diseases.
Just put down a round of Milorganite on my NPP treated lawns.
Fingers are crossed, updates in June.
Put down 2nd app of NPP on lawns infected with NRS. Did so at the curative hi rate, as some of the familiar 'frog eyeing' was just starting to peek through. I freaked and did the 2nd app of the product soon thereafter, thoroughly dousing the worst areas with NPP mix.
Went back to one of those lawns today (week after app), and the frog eyes were much less noticeable.
Really, my booty is on the line using NPP, milorganite, hi mowing, and aeration to combat NRS. If this doesn't work for me and my customers, I won't be feeling real great about it. So far, some promise but the jury is still out until we get through July.
I'm still curious... are we still only treating the symptoms with these products???
I don't see that organics selling stuff to treat symptoms being that much different than treating symptoms synthetically...
please understand, I'm not knocking anybody's products, I was just noticing that things aren't really any different here...
Did you forget to read this part? using NPP, milorganite, hi mowing, and aeration to combat NRS
He is addressing the problem by using cultural practices in addition to treating the fungus directly. There are no silver bullets here, it's all part of a program. Proper irrigation should also be included with in the program.
Cultural control practices are targeted
to minimize the effects of necrotic ring
spot infection. Management practices
that promote deep rooting during spring
and fall will help reduce the extent of
necrotic ring spot symptom expression.
Also, the effects of infection will be
reduced with practices that relieve
summer stresses associated with
compaction, drought, and nitrogen
deficiency. These include implementing
a balanced nitrogen fertilizer program
(preferably with slow-release sources
of N), re-directing traffic where feasible, and judicious use of
Although there are differences of opinion, most researchers
favor deep, infrequent irrigation as part of a program to reduce
the effects of summer stress on infected turf.
Barry - irrigation is one thing my customers do not do beyond what falls from the sky. Isn't any way I could get them to water systematically and correctly all summer long. Wish I could, but nope.
So, how does a good watering program serve to minimize the impacts of NRS? What moisture level (or lack thereof) does NRS seem to thrive in?
Water deeply and infrequently but make sure to avoid any drought stress. Try seeding with perennial rye too as it's immune to NRS. I always overseed with nearly a 50/50 blend just for this reason, plus the PR germinates so much quicker than KBG.
I don't think the NPP works. I'm not knocking it or trying to diss anybody, but I have not seen it do squat on anything I have applied it to. The tea on the other hand I think is quite nice.
It thrives in prolonged wet conditions, think rotting.
If you can't control all the environmental variables to prevent it, well
Spraying preventative and curative apps of chitin for NRS is like wiping with sand paper, yeah it feels like your doing something butt at the end of the day
what was gained.
