Herbicide dispensing made easy, more efficient with new system

PrecisionPac 3.0 dispensing is the next advance in the effort to allow producers to buy the exact volume of herbicide they need, down to the last drop.

The PrecisionPac delivery system, which DuPont announced last week at the Ag in Motion farm show near Saskatoon, was first introduced in 1999. However, it has been re-designed to dispense customized herbicide blends.

The new 3.0 machine incorporates the latest technology so that it dispenses three times faster. This is possible because it meters all herbicides into the bag at the same time instead of one at a time, says product manager Rob McClinton.

“Most crop protection products are sold in packaged 40-acre increments, leaving leftover herbicide and packaging to dispose of,” he said.

“PrecisionPac 3.0 lets a grower purchase a tailored blend to treat 132 acres for example or 92 acres. This saves money, reduces unnecessary packaging and decreases the risk of application errors.”

One hundred and a eleven prairie farm supply retailers are equipped with PrecisionPac units. McClinton said DuPont chooses dealers that have agronomists who show a keen interest in working with growers on precision agriculture and customized herbicide technology.

“A grower comes into his retailer to sit down and talk about specific weed challenges in each individual field. They look at length of activity, type of weeds, cropping system, field history and things like that. The agronomist has the knowledge to put together the right blend for each field.

“He specifically tailors the blend for the weed mix in and for the size of each field or for the size of the sprayer tank. He dispenses that blend immediately while the grower waits.

If the field is 109 acres, the bag will have just the right amount of herbicide for 109 acres. It’s ready to pour into the tank. The machine is currently able to blend bags up to 320 acres in non-crop fields or 240 acres for cereal broad leaf fields. We’re looking to expand that for bigger size fields in 2016.”

The new units, with six products, have an option of having four of those gravity fed by mini-bulk containers rather than just the smaller bags of chemical.

“We have dealers that are servicing more than 200,000 acres with a single unit. They are constantly changing bags, so this will make that more efficient,” he said.

McClinton said the inspiration for PrecisionPac comes from farmers.

“Yes, it did happen here first. It’s all based on a need Canadian farmers expressed to DuPont reps here years ago. They told us what they wanted, so we sent the engineers some rough drawings,” he said.
