You want to apply @.25 lb ai/acre or .75 oz/1000 sq ft. Price paid in 2003 was $270 for 2.5 gallons. I have found the best approach for crabgrass control is to use granular in round 1 and go with with liquid dimension in round 2 , spraying just your hot spot areas i.e. tree belts, driveway edges, and sunny areas prone to crabgrass. Taking an extra five minutes or so on round 2 to do this will eliminate service calls for crabgrass in July/ Aug , reduce post emergent material cost, and make you look like a hero! However, since swithcing from pendimethalin three years ago, I have found that spotted spurge has become more of a problem. Seems pendi help control spotted spurge better than dimension.
Dusty - I do need to find out the lowest recommended amount of mix per k.
I plan on using a granular fert with team for my march/april ap. I was looking into using the liquid dimension for my 2nd ap mixed with my broadleaf control. This may not work if I am going low volume.
To answer your question about the ride on unit not being able to be used for this type of ap. The z spray can spray at different rates per k depending on the nozzles. I can put out 1 gallon per k if I choose either my changing the nozzle or adjusting the speed I am traveling. With my low volume aps I put out .20 gallons per thousand square feet.
Agro lawn - what are your thoughts on late winter dimension aps and its effect on fall overseeding. The label recommends waiting a year on some types of grass? My thoughts were to use team 1st and dimension as the 2nd of the split ap to give the younger grass more time to root. Just a thought.
We offered a 2nd treatment of crab to customers this year on our renewal form, I plan on using the perma green and spraying dimension, however when I did my budget for this service I used acclaim as my basis so if I have to that will be my product.
Right now 90% of customers are signed up for the season with 55% taking that 2nd treatment. I sure wish I thought of this a few years back
turf- Any lawns which were overseeded in Fall would be better off with a straight fert in round 1; usually last week March / first week of April. Apply Dimension early May for round 2 @.25lb ai/acre. You might want to let customers know who you seeded in the Fall that their lawns will probably get some breakage with crabgrass this first season . Just think you should wait at least until first week of May before running Pre-emergents. Dimension will give you a longer window being it is labeled for early post emergent. In regards to other pre-emergents, Have used pendi in liquid(EC) yellow and smells. Barricade has a longer residual and supposedly works better on hilly lawns, have yet to try it, also a little more expensive and I believe can only be purchased in 30 gallon containers on the liquid end. Also never used dimension through low volume in perma green. I usually apply tank mixed @2.5-3.0 gal./1000 and get excellent control.
agro lawns - I appreciate the response. I don't think it would be a good idea to go until May before applying pre emergant. The soil temps hit crabgrass levels in late March early April around here. Not sure how it is in Ct. Last year was the worst year for crabgrass since I have been in biz. I agree that putting down dimension in late march early april may be a bad idea. I was curious how others felt on the matter.
I will be putting down team with fertilizer on the first pre m ap. and possibly dimension liquid on the second. I still have not heard from the company. I emailed them asking what the recommended carrier should be for the liquid dimension. Their label literature on their website just said use a sufficient amount of carrier. Not too specific.
2003 was the second year in a row that Crabgrass didn't germinate in one big push in Southern New England. Usually we see a flush of germination during the first 2 weeks of May. But no such flush has occurred.
Instead we're seeing constant germination with irregular peaks right through August. So single applications of all Pres have failed for 2 years in a row.
No matter which Pre you use, 2 applications is becoming mandatory unless you like spending your summers spot spraying service calls & jumping through hoops to prevent cancelations.
Offering a second application as a chargable option isn't a bad idea since it get's you off the hook to some extent for failures. But for $18 per acre, I'd probably just stick it in the program & enjoy reduced customer turnover & get more referals instead. Satsfied customers & referals pay for themselves.
.188 lbs AI/A is the low Dimension rate for the Northeast. The EC form is not as effective as the newer Dimension Ultra due to volatility issues. Ultra also doesn't smell as bad either.
Forget low volume machines like the PermaGreen for any liquid Pre. Indeed the majority of broadleaf herbicides aren't really legal at these low volumes regardless of how well they work.
