| Going to spray some burndown on last years corn ground going to beans. Going to spray Sharpen, Methelated Seed Oil, and Buccaneer Plus. How many gallons per acre of water should we be spraing? Is 10 gal enough? Is 20 overkill? Chemical man says we need 20.
How about when spraying just Bucc Plus and Gly?
How about when spraying for L. L. beans?
Thanks,
Todd |

| Read the fine label. Different brews need different amounts of water. Some get along with a small amount, some demand more water. And the minimum amount of water is affected by the nozzles used. Teejet told me don't go under 8 gpa with glyphosate and air injected turbo Tee nozzles because the drops are big and lower rates might miss hitting weeds.

WC Ohio | 10 gal. works fine here with Sharpen, MSO, Round-up |
|

|
Central IL | you will be happier with 15 gal |
|
| |
|
mn | 10g/ac here |

Definitely true if you are going after marestail. 15 is noticably better than 10. |

United States | I used 12 gpa this spring using round-up + sharpen + scepter worked great.

Northeastern North Carolina | I would use 20. Water is the cheapest ingredient in the tank, I would hate to not get a good kill because of it |

Eastern Iowa | Depends on how dense the weeds are with Sharpen, if you have thick winter annuals go higher on water, did some at 15 this year and worked great. As far as glyphosate, it works better the more concentrated you keep it, total coverage is not as important. With good AI tips you can be very successful spraying 10 gal/acre with glyphosate, then as you bring the rate up you really increase the concentration. Glyphosate is an excellent translocated herbicide, make sure to use AMS or some type of liquid pH adjuster and you will be fine. As far as Liberty or Ignite go higher water volumes and flat fan tips, 15 gal/acre minimum, 20 is better, pressure helps too.

North Central Illinois | Good info on the glypho Chris. Some of the glypho lables don't reccomend using anything over 12 gallons. |
|
| |
|
WC Indiana | I always use 5 gal/acre on glyphosate and 7 gallon on everything else like Halex or fall burndowns . Everything dies and I get a lot more acres per tankfull. Been doing this for 5 years now with very good results. I feel very comfortable with glypho at low rates.
Always has to be a contrarion.

Eastern Iowa | No problem with this if you've got good tips. I've got a big tank and most label recs don't go under 10 gpa. Most custom guys around here are 15+ gpa, I think out of tradition. With contact products you need more water though, I wouldn't try Ignite at low volumes. |

Ohio | I use what the aerial app. calls for. If a plane can spray at the speed they do , from the height they do. Then why can't I spray within 3' of the ground and a fraction of the speed and not get as good or better kill that they. Glypo works best with a higher concentration droplet. The less the carrier the stronger the droplet.Things like this are easily varied to prove to yourself what will or will not work to your satisfaction. Don't take the reps word as gospel, try your own combination and see.

North Central Illinois | That is true but if you go off label and something goes wrong, don't go crying to the rep. Just sayin. |

Emporia, ks | 5 GPA here and never had a problem. Simpson's told me people in western Ks are using less than that. They said the same thing using Glyphosate...less water is better. |

Northern ill | I would say that the custom guys spray at 15 - 20 gpa because some products need better coverage to work better and sometimes have to spray in more adverse conditions than you would if you could pick the perfect time, and the chances of needing a respray because of poor performance is less spraying a higher gallonage than an ultra low arial type rate. Once your setup to spray at 15 its just as efficient to spray everything at that rate. If i had a hose break and lost 10 gallons of mix, i would rather not have it be 3 acres of material. |

| But your sedate spraying on the ground doesn't include a 600 hp blower stirring the 3 gpa into the canopy along with the wind deflected by the wings.

Eastern Iowa | Agreed Steve. Last I checked I couldn't put the flaps down and blast the field with the downdraft off my wings on my ground sprayer! Planes are a different story than ground rigs. We like a helicopter for fungicide because of the air blast coming off the rotor, costs a little more than a plane but is better in tight places IMO. |

SW KS | at spray rates. I feel that a higher concentration of product works better 'here' than not. The reps are really starting to back off the 10 gpa rate and realizing that we do a better job at 5 gpa or less. Like mentioned above it does require the correct nozzles to work. At low rates the AI's should be left at the store. |

If it were glyphosate only, I'd agree, but the original post included Sharpen and more water is definitely better with Sharpen. Marestail is usually the weed that attracts the use of Sharpen here and from seeing it sprayed 15 is definitely better than 10 which is going the opposite direction for best glyphosate performance, but may be necessary at times. |

How much water to spray?
