Re: Later Summer Lawn Quality
Carbohydrates are lowest right now, so any continuing Summer stress can rapidly lower turf quality this time of year. Keep the blades sharp, fungicides at the ready just in case, and start fertilizing again as soon as your weather permits. This is a great time of year for the high lift blade you men...

Re: Fungicide PGR Effect
Hey oze. Great observation! I was actually just talking with an expert PGR user on this exact topic. He said that on short maintained turf, the growth suppression from Propiconazole (measured in clipping reduction) is likely about 18%, and the duration of that being around 400 to 600 growing degree ...

Re: Late September planting - Minnesota
Definitely incorporate Perennial Ryegrass. If it starts cooling off and you're desperate, you could throw some of the annual rye in...but it will make a mess of the lawn next Spring.

Re: All Crabgrass?
The photos are tough to evaluate, but something doesn't look right to me. My gut feeling and advice: see if you can rule out Dallisgrass/Field Paspalum/Bull Paspalum. These species have the V-shaped seedhead, and grow in tight upright bunches or flat mats, depending on the species. The don't root at...

Dylox is much more risky to the applicator than the preventative insecticides.

Re: Grub treatment now
There are 4 main grub prevention active ingredients used today. The first two are chemical insecticides: Chlorantraniliprole and Imidacloprid. They are used in tye first half of the season. It's too late now. There are also two biological products... The first being Milky Spore, but it's next to wor...

Re: Reseeding lawn and pre soak grass seed
Regarding the pre-germination itself: Ideally, you don't want the seed container submerged in the water the entire time. More like a few hours in water, then out of water for a longer period...rewetting for short periods every so often so it doesn't dry out. Grass is not an aquatic plant, after all....

Re: Suspected poa triv not lighting up (white) from Tenacity
Sometimes, I think when energy is going to produce seeds, as Poa annua is now, it takes grasses longer and/or takes a higher dose of herbicide to impact them. Maybe there is less translocation going on. I've also seen the inverse: Triv switching to more seed production after hitting it with Mesotrio...

Re: Fertilizer and rainfall.
Morph,
What's your take on how much risk there is of losing nutrients if you apply your soluble fertilizers toward the end of a large rain event when most of the rain accumulation has already occurred, but the ground is already saturated?

A forecast of 1.5 inches can easily turn into 2, 2.5, or even over 3.5 inches, as I found out recently.

I also sprayed an 8% humic product. On some areas, I did it right before the rain; other areas got it a week ago.

Re: Runoff a major concern after heavy rain?
The pre-M is the most important part. Good to hear it probably bound. The fertilizer was a mix of urea, polymer coated urea, and Milorganite. Mostly water soluble urea at 70%. I applied no more than 0.25 lb of N per thousand, total, counting all three sources. On the sloped portion in the front, I a...

Runoff a major concern after heavy rain?
An inch and a half of rain was forecast. I put down fertilizer and pre-M. Of course, we get almost 3.75 inches. For areas that border roads, what happens after that much rain? Environmental activists want you to believe that everything in the soil solution (or a portion) will tend to move with the w...

Re: Who all has put down Pre Emergent?
Finally got it all applied over the past week or so. Then the rain came the other night...and didn't stop unitl almost 3.75 inches came down. Good for the fright, but probably not so good for pre-M and fertilizer as far as the environment and runoff goes.

Re: Who all has put down Pre Emergent?
So far, I have applied my first split app of pre-M on less than 6,000 square feet. Additionally, only 0.55K or so has been watered in. Some is Prodiamine, and some is Dimension. I know I'm flirting with being a little late (especially with the Prodiamine as it's less soluble). I recommended to my fr...

Re: Spring PreM with large fall overseed?
Keep in mind that Quinclorac and Mesotrione can both act as short-term pre-Ms due to a 20-45 day (or so) residual in the soil. This is a good thing, because you get a pre-M type of effect without using a real pre-M.

Looks like they're combining the glyphosate with Pelargonic acid to speed up browning. See the wikipedia article for a bit more info.
