Ornamental turf quiz

[lorenzo piedra]

Today starts round #1 of my ornamental turf applications. If you have applied a preemergent combination product way back in early April in zone 5 all you have done is wasted your cash, chemically pruned your roots, stifled rhizome production on KYB, increased your mowing costs, and you will have to apply ANOTHER combo application now to be able to control the June (main) crabgrass germination.

Finally the good folks at Lesco have created a combo product the I can live with. It's their item #080376 - DIMENSION 0.10% 13-2-5 30%PPSCU.

My cost per 1K for this product is around $1/1k sqft.

Now for the quiz:

As per the label of this product (which is linked via the above URL) at the program #1 high cut northern turf rate of 2.86 lb of product per 1K sqft how many pounds of N is applied per 1k sqft?

Bonus question:

What is the Lesco spreader setting (numbered gage setting) when applied at the above rate?

Okay, just came out of my State of NJ Pesticide training courses last night, (10 hours in total) so I will give this a try.

As for the Nitorgen, I believe you are putting down .37 lbs per 1000 sqft.. I think. If I am wrong, please tell me where.

As for the setting, it depends on the Lesco spreader. either #13 or 18 for the Lesco Pendulum spreader.....

C'mon, lorenzo pebble, you can troll better than that.

If you are concerned about root pruning by pre-ems, the only answer is to not use pre-ems. Last year's application of pre-em is still pruning your roots, so delaying this year's app doesn't help much. You will not see root recovery until the second year after pre-ems are stopped. In fact, if you are using the same pre-em for the fourth or later years, studies have shown there is enough residual that you only need to apply your pre-em this year and later years at half rate for good control.

KBG rhizome growth occurs mostly in the late fall, after topgrowth ceases and before the ground freezes. In mild winters I have seen rhizomes grow up to 16". So your statement about "stifled rhizome production" in the spring is again erroneous. Spring is when the existing rhizomes pop up new grass plants.

Jim I have had to break down and apply a pre-m combo product this year due to some major crabgrass breakouts last year from the 50" or so of rain that fell for the year. Being pre-m "free" for a few years has produced too may seeds to ignore with just straight fert for this germination cycle.

These people are having a big party (250+) at their $500K house (that's a $900k house in NJ, NY, CT, Phila.) on 2 acres next month and I am going to hit the place with a 4 way selective, talstar, and 20-20-20 at a 1/16 lb of N per 1k sqft this week. There no irrigation (as usual in my area) and I just hope it does not stop raining.

I can see a potential of 5-10 new full service estate jobs coming from just this one event for it sure beats advertising the penny saver!!!!

Back to the top!!!!

I just wanted to follow up and say that the above product (Lesco item #080376) has worked as advertised at the above rate. It gave a nice little green up without generating excessive clippings. The turf is crab free even where it meets blacktop and concrete.

As for the quiz, the amount of N would depend on whether the product was applied within three days of the full moon. But only if applied before the vernal equinox, unless Easter falls before April 6. Therefore the formula would be 2.86 lbs multiplied by the square root of the last four digits of my social security number plus my age divided by the numeric equivalent of the month I was born. If my calculations are correct, (i.e. the moon was full) a little over 1/3 of a pound.

I can't figure out how you got the right Number without using Avogadro Number and Loschmidt's Constant. Now if you first multiply by Avogadro Number and then Divided by Loschmidt's Constant, you can multiply again by Loschmidt's Constant and then divide by Avogadro Number for a more impressive answer unless you are a fish. However even if some people use the Intelligent Quotion method Minus the G Factor they will not be able to bite the correct Lure.
