Wow, I do it completely differently. In my program (by the way, I’m located in Springfield, Missouri) I run a six round program. And there as folllowed
Round 1- start late feb early march. Consists of prodiamine, nitrogen & 50lbs/acre in the form of Urea. And sublime(new product) which has a combination of triclopyr, dicamba and mesotrione. According to the sublime label, it can be used to blanket app four times a year.
Round two – I have half the amount of the prodiamine, Nitrogen, I add Pot ash, same rate of sublime, and I add a non ionic surfactant like 90/10.
Now round 3 (about late April- early June) I have the potash, the sublime, the 90/10, but I only go with 25 pounds an acre of nitrogen. And I’ll also add some chelated iron. And also Bandit for grub control (help with keeping the mole activity down in August and September)
Round four is in the summer so I don’t do a blanket application. I will just spot spray and my mixture has Quinn way sublime MSO and sledgehammer. And my spot spray I’m mainly looking for weeds, nuts edge, and I can also use that not to kill Bermuda, but to at least keep it at bay if Bermuda from a neighbors yard is trying to creep into theirs.
Around five – i’ll have potash, the iron, sublime, 90/10, and nitrogen when I start around and the temps are up I’ll have just 25 pounds per acre, but as the temp starts to cool towards the end of the round, I will bump up that nitrogen. Though this does coincide as the same time that we are doing lawn renovations for people, so it is always good for me to keep in contact with my customer to see if they’re planning on putting seed. Now the sublime says I can spray on the same day as seed, but we just don’t want to risk you know then paying all that money and the seed not germinating so anyone that is having a lawn renovation I will run the same mix just without herbicide.
Round six is our winterization round- boost up the nitrogen and this is the round that I’ll run lesco’s three-way, which has 2–4 D.
and this program has been working pretty darn good for me. I finally tweaked it over the past few years to get it where I have it now., Next year, I’m gonna study and think about some wedding agents for the hotter months and maybe a growth regulator for the early spring you know because it’ll keep it from growing tall, but it will grow thick and be more full. So maybe when the drought in the heat comes in summer, the yards won’t be under as much noticeable stress with patches around trees, etc..
Now this is just my opinion, and what has worked for me so not saying that this is how everyone should do their applications. I’m just new to the form and thought I would share what I have learned along the way thank you for your time.
