Frequently Asked Questions
Q. - HOW DOES THE G3 TREATER WORK, AND WHY IS IT DIFFERENT ?
A. - The G3 has a simple purpose; - to apply treating on the seed passing
through it as accurately and uniformly as possible. This maximizes the potential benefit from
the treatment. The field treating benefit is reduced by the
amount of seed that doesn't get properly treated.
Auger based drippers or spray nozzles initially contact less than 50 % of the seed.
Unless special mixing fixtures are added, augers aren't great blenders. Augered grain
tends to flow with little turbulence, so mixing is usually less than 10 %.
This means that you have 100 % of the treatment on less than 50 % of the seed. Some
is under treated; some is over-treated; 30 % probably has no treating at all.
Your treating benefit per acre just took a big drop. Treating must be on all
seeds to provide effective disease control, and give you the best payback on treating cost
By its design, the G3 makes sure that each kernel receives accurate treatment dosage, so
the crop benefit is maximized. The G3 does this by first
spreading the seed into a loose air curtain.
The treating is then cross applied at a diagonal, for best curtain penetration.
The application nozzle is a controlled droplet hollow cone, for high penetration and
coverage. Primary treatment accuracy at recommended seed flows is over 85 %.
With the G3, coverage is well over 90% at the mixer discharge. Your crop
protection and treating benefit are at their highest potential value.
Q. - CAN WE MOUNT THE TREATER ON THE DISCHARGE OF AN AUGER LOADING A TRUCK?
A. - Yes you can, but.. potential chemical spills or drift
from an elevated treater are very hazardous to people and equipment. Also,
calibration and supervision of an elevated unit is very difficult. For those reasons, we strongly recommend the treater be mounted at ground level
and grain moved onto the next stage by an auger or conveyor.
Q. CAN WE PUMP SUSPENSION TYPE PRODUCTS WITH THE P2 / P4 SERIES PUMP?
A.- Not for very long. Suspension products with solids mixed
in the liquids will plug pumps and nozzles, eventually shutting
the system down.
Peat base pulse inoculants, poorly stirred Thiram mixes and similar
blends can all cause trouble.
Q.- WHAT GRAIN FLOW RATES CAN BE TREATED WITH THE G3?
A. -The G3 was developed to work with 6 or 7 inch auger flow rates. The range
of best distribution accuracy is between 17 and 25 bushels per
minute of corn or barley, or 15 to 22 bushels per minute of wheat, barley, oats or rice. Outside
this range distribution accuracy drops off. As with any machine,
it will operate outside it's optimal range, but won't do quite
as good a job.
Pulse or cotton treating requires a higher application rate, with slower flows, to get complete
seed coverage, and remove the need for secondary mixing. Thus pulses and cotton are best treated at
16-20 bushels per minute (960 - 1,200 bu./hr.)
If the grain flow through the G3 is reduced below 14 bushels
per minute, the chemical rates becomes so low the spray pattern
is lost, and seed coverage is reduced. Also treating chemical
will penetrate the grain curtain, and run down the inner wall
of the treater, causing a mess.
Grain flows over 28 bushels per minute are so dense that treatment droplets
are prevented getting to the outside of the grain stream, reducing coverage accuracy.
Q. - WON'T THE G3 WEAR OUT AFTER A FEW YEARS?
A. - We've had G3's in service for over 8 years, and see no signs
of wear. The galvanized metal is quite durable. Plants running high volume through a single
treater may elect to use 304 Stainless Steel G3's. This removes any concerns about wear
and makes cleanup much easier, as the galvanized units tend to show staining and hang up dust more.
Q. CAN G3's TREAT OTHER CROPS BESIDES CEREALS, FLAX AND PULSES?
A. - Yes indeed. G3's apply liquid treatments to soybeans, corn, cotton, rice, peanuts,
or any large seeded crop. They're being used
for Apron®, Crown®, Thiram®, and Vitaflo® 280 mixes to peas, chickpeas and
lentils in Canada and Australia, and ApronMAXX to soybeans in Argentina. Their accurate
rate application and gentle handling makes them even more valuable in pulses than in cereals.
Higher volume nozzles are used in pulse treating, applying up to 200 millilitres (6 oz.)
per bushel of treatment. This higher moisture volume provides two benefits.
- It softens the pulse hull, giving them much better fracture resistance in further handling, and
- makes secondary mixing unnecessary.
The G3's high primary application uniformity insures the seed is completely treated at the G3
discharge. This removes the need for drums or other secondary mixers, which
add cost and potential seed damage to the process.
Q. CAN G3's APPLY THE NEW INSECTICIDES?
A. - Uniform application to each seed is essential to get the best field benefit from the new long duration insecticides. That's always been the strong point of G3 applicators. The insecticide application rate is so low that they will usually be tank mixed with a fungicide carrier and co-applied. G3's were broadly used to apply Cruiser, and Gaucho 480 last year in the U.S. onto soybeans and cereals with good success.
We have pre-calibrated the G3 for Cruiser 350FS and 5FS mixed with Dividend RTA, Dividend Extreme Warden RTA and ApronMaxx RTA. Gaucho 480 premix calibrations will be available when it receives registration. This allows instant field use, without messy field calibration needs.
Q. WHAT OTHER PRODUCTS CAN G3's APPLY?
A. - Many new seed enhancement products other than pesticides are appearing. They are all aimed at improving crop yields, by adding nutrition, seed vigor or growth stimulation. Liquid inoculants with stabilizers now have field performance equal to peats provided they are applied uniformly.
Micro nutrients supply early season nutrients to the seedling when it can't access soil supplies.
Many hormonal products stimulate plant growth in a variety of ways. All these products can be accurately G3 applied provided they are true liquids, not suspensions.
We have pre-calibration charts available for most liquid inoculants, Jumpstart, Phosyn's Teprosyn and a number of other minor use products.
