Valtera vs Authority 480

[malleefarmer]

We've used Authority, I think its pricey for what it does. But I do like the kochia control.

If you want, go to 40 acres per jug. The low rate is 43 acres per jug and the high rate is 32....that gets real pricey. Costs are about $14-$18/ac....depending what you have to pay for the stuff....shop around!

Sprayed on after seeding would probably provide the best control(uniform layer), probably prevent strip misses from the openers "furrowing" treated soil during seeding if applied preseeding.

You will need .25 to .33 of an inch of rain to activate it, it can lay there and wait because it doesn't photo-degrade, but won't control much either without the activating precip.

We will start using more pre-emerge herbicides because of herbicide group resistance, 1 & 2.
We bought a used heavy harrow with mounted Valmar. Time to start mixing things up a bit more.

Good luck this spring Helmsdale.

Dumb question farma with your spraying do you increase your speed and pressure stays constant or vice versa see you speak of acres per jug and figure it must be one or the other.

Once decided how much we are going to apply, the application rate of the herbicide on a per acre rate is çonstant, "X" grams active ingredients per acre. Then we decide how many gallons per acre of the solution we are going to apply... 5, 7.5 or 10 gallons per acre or whatever, here is were you need to pick a nozzle that is capable of applying the solution at the volume you chose at the speed you want to travel. Since all nozzles have an acceptable operating range for which it was designed, pick one which has it's optimum application rate that matches the rate(speed and operating pressure) at which you want to apply. Then if you vary your spraying speed, a bit faster or slower, the sprayer's auto rate controller will compensate for the faster or slower speeds.

That was kinda the old school method.

Guys are using pulsating tip technology where every nozzle has a pulsating solenoid incorporated into the nozzle body that delivers more or less product through the nozzle according to application speed. I think the sprayer's auto rate controller delivers a more constant pressure and the nozzles do most of the rate adjusting(according to travel speed) in such a system. This technology has even evolved to the point that if you are going around an obstacle the nozzles on the outside of the boom, that are in essence traveling faster than the inside ones, will pulsate at different speeds to apply the correct amount of solution per acre across the boom. Lots of additional wiring and moving parts(solenoids) with this system. But it eliminates large section "sectional control" as each nozzle will shut off independently as it approaches an area that has already been sprayed. Our sprayer isn't fitted with this feature so we operate using the first one I explained,

So in theory, we don't increase or decrease our speeds or pressure to change application rates, if we picked the correct nozzle size, the sprayer compensates for the changes in speed we travel by increasing or decreasing spraying pressure, the job of the auto rate controller.

Choose the herbicide application rate, choose the volume of the solution you want to apply, use the approriate nozzle and let the sprayer do the rest. I think I complicated the response, lol.

Just unusual to here the acre per jug.

We buy chems mostly in 110 litres or at times 1000 lt shuttles

If you need to put in 63 litres of product a and 27 litres of product b and 3.5 litres of product c we do it that wereas you guys simplify it.

Not a criticism just a observation
