SPRAYING GRAZON

Just rebuilt my smaller spray rig and was going to spray some grazon on pastures. Just curious how some of you gents mix. I was thinking about 1 quart and 10 gallons to the acre but had it recommend to me to use a 11/2 to 15 gallons of water
 
I have sprayed pasture with 10 gallons of water and grazon and got excellent results, but that was in the spring just after most of the weeds had emerged. The instructions with Grazon give a pretty abundant range of rates to use, depending on what your target weeds are. Some are harder to kill than others and need a heavier dose. It also depends on which state you are in. Read the instructions and you will be able to determine what rate would be best. In a larger pasture we have been using aerial spraying for the past few years and had excellent results from that also. It does a fair job on woody plants like plum bushes and wild rose but will probably need a repeat application in a couple of years to get a nearly 100% kill. This is in central Kansas.
 
Brother had some problems with his beans this year, talked to agronomist and where ever my brother spread his manure from the cow lots was the bad areas, the grazon carried over in the manure and hurt his beans. So spread your manure in next years cornfield. Northeast Nebraska chris
 
According to the label on Grazon, you should not use manure from livestock that have grazed pastures sprayed with Grazon or been fed hay sprayed with Grazon for fertilizing gardens, etc. Grazon is livestock safe because the pesticide is not absorbed by the animals, but is passed in the manure. I forgot about this last year and used some manure when I planted some tomatoes. It didn't take long for them to die.

In some states you have to wait 18 months after the spraying to sell hay/forage. This is on the label. Some states, like Texas, have what is called and "additional label" that exempts them from this restriction. You can check with your ag agent on this.

Grazon is a broad leaf killer. If the veins in the leaf go out from the center vein toward the edges, then its a broad leaf plant. If the veins run parallel to the center vein, then its a member of the grass family and SHOULD be immune to the herbicide.

Legally, you can't spray a herbicide on anything that's not listed on the label for that herbicide. If corn is not listed as being ok to spray, don't. Like David said, always read the label for the correct mix rates according to the weed/vegetation you are trying to control.

BTW, when you read the label, control = killed, suppressed = hurt bad, but not necessarily killed. Once I've read the label, I use a permanent marker to write mix rates, etc., on the jug or the case so I don't have to remember rates, restrictions, etc.

We have used Grazon for many years with excellent results. The newer version, GrazonNext HL has a mix rate of 24 ounces per acre for most applications. The older version was 1 quart (32 ounces) per acre. It really kicks the snot out of berry vines, horse nettle, bull nettle, kudzu, wild flowers and many other things you don't want in your pastures. It even puts some serious hurt on cactus. It will take out small seedling trees that are under 2 ft. Over 2 ft can take more than one application. In my opinion, you get a lot of bang for your buck with Grazon.

One other benefit to Grazon, wild hogs don't seem to like it much. Fields we have sprayed with Grazon rarely get damaged by wild hogs.

In my opinion, using 10 gallons per acre is a little light. That means you may not get enough spray on the vegetation to do what you need. Our spray rate is around 28 gallons/acre. Our ag agent says a minimum is 22 gals/acre.

One of the components of Grazon, pickloram (sp?), can inhibit growth on coastal hay fields when used more than 2 or 3 years in a row. If you are spraying coastal, you can probably use Grazon two years in a row with no issues, but plan on using something different the 3rd year. Rotating each year is an even better idea.

Hope this helps.
 
I should be getting my grazon next tomorrow and will read the container and see what it recommends. My dealer recommends at least 15 gallons of water and 11/2 pints of the grazon next to the acre using TeeJet XR8004VK tips. I will be spraying dog fennel and horse nettle mainly. Thanks for the comments
 
If he uses 1.5 quart in 15 gallons per acre he gets half again as much herbicide per acre as he would at 1 quart per acre.

With 15 gallons of water per acre you get more coverage.

What may have confused you was he did not add "per acre" behind the 1.5 quart and 15 gallons.
