How To

Application time for Pre-emergents

Pre-emergents  will not control weeds that have germinated prior to application. So you need to apply a pre-emergent 
 
several weeks before germination. If they are applied too soon before germination, the herbicide may lose its effectiveness. 
 
For the fall a good rule of thumb is to apply a pre-emergent the third week of August to mid-September.
 
Exact dates are hard because it has to do with location and the weather temperature at the time.

Is this effective for Dallisgrass? If not what is best pre emergent for Dallisgrass? I have 1 acre bermuda grass lawn in Texas.
Sean on Jun 12, 2017
BEST ANSWER: Yes, it will work for Dallisgrass if you can apply at the correct time. Postemergent The postemergent herbicides MSMA or CMA (such as Weed-Hoe or Weed-B-Gon Crabgrass Killer for Lawns) can be used by home gardeners to control clumps of dallisgrass growing in lawns. These herbicides are relatively selective and must be applied two to three times at 3-week intervals in the summer. The turfgrass and dallisgrass should be in good growing condition before application. Also, it is best if the turf is left unmowed for 2 weeks before the first application to create the maximum amount of leaf area for coverage by the herbicide spray. Withhold irrigation for 24 hours after application. Don�t apply these herbicides during extremely hot weather and check the label for rate adjustments during warm weather to minimize the risk of injuring the turfgrass. There are some restrictions on turfgrass types where these products can be used, such as on St. Augustinegrass.

Foramsulfuron (Revolver) is a new postemergent herbicide for control of cool-season grass weeds and turf species in warm season lawns. It can only be used in bermudagrass and zoysiagrass lawns and has good weed control activity on dallisgrass, but be aware that it is harmful to most cool season turfgrasses. This product is only available to professional applicators at this time, but may be used on residential lawns.

Can this be used in grass pastures that aren't being grazed but that are strictly cut and baked for hay fields to feed cattle. A spring application with round up pro and LV-6 would seemingly leave a clean field with a residual through growing season.
Okie Spray guy on Feb 22, 2017
BEST ANSWER: No Prodiamine cannot be used on grazed pastures, but does not list pasture grass for hay on the label. It appears Grazon has a pre-emergent and could be used, but it does require a license.

will prodiamine 65 control johnsongrass?
rockytop on Oct 7, 2016
BEST ANSWER: HOW PRODIAMINE 65 WDG WORKS PRODIAMINE 65 WDG controls susceptible weeds by preventing growth and development of newly germinated weed seeds. Weed control is most effective when PRODIAMINE 65 WDG is activated by at least 0.5 inch of rainfall or irrigation or shallow incorporation (1-2 inches) before weed seeds germinate and within 14 days following application.

Yes you can use this to control Johnsongrass and a large extensive list of other weeds.
what can i use to control johnson grass and not harm other pasture grasses?
rockytop on Oct 7, 2016
BEST ANSWER: Prodiamine is labeled for control of johnsongrass, but it will also prevent any other type of pasture grass from germinating.

Clumps and individual plants may be hand pulled during June, just after a rain when the ground is soft. All plant parts should be removed from the area. Broken stems and roots left in the ground should be dug up if only a small area is involved. It is more effective to spot-treat the individual plants with herbicide than to pull them, and large clumps can be sprayed with 2 percent�Roundup using a hand sprayer or backpack sprayer. Herbicide treatment may need to be repeated for several years to ensure good control.

I have a ton of bluegrass mixed with red fescue and tall fescue. Will this kill my bluegrass in upstate New York.
DWeaver on Apr 14, 2016
BEST ANSWER: Prodiamine will not kill actively growing bluegrass. It is a pre-emergent herbicide. You would put it down in the fall to prevent any new growth in the spring. To kill active bluegrass in fescue you can pretty much only use glyphosate and reseed or weed it up. If you have poa annua then you would use ethofumosate but it is very expensive for the benefit.
I grow a large number of roses. The plants are mulched with wood chips. I am looking for a product to control weeds in the beds and under the plants. Many products indicate direct application to the soil. Is that the case with this product?
Central Florida Gardener on Apr 7, 2016
BEST ANSWER: Any pre-emergent herbicide needs to reach the soil to be effective. They work by preventing seed germination in the treated area. Most people treating mulched areas will use extra water to ensure the active ingredient gets down to the soil and will be effective. If applied properly pre-emergents need to penetrate the top 8" of the soil level as that is where seed germination typically happens.
Would be very helpful to make it more clear in writing (vs in the video, where I eventually found it explained) that this is a "mix-from-granules" product, as well as what the dilution is (2T per gallon, for 1000SF), again, mentioned only in video...
808boy on May 25, 2016
This is called a pre emergent but it says "Prodiamine should kill weeds" on the website. Does it do both kill and stops germination?
