Picking the highs and lows and making the field whole

The Climate Corp.’s FieldView has added a crop protection prescription tool farmers can use to create variable-rate scripts for any zone in their fields.

“For a fungicide, think about a canola crop or a soybean crop in Eastern Canada where the more biomass we have, the more risk we have for sclertoinioa or white mould,” said Marvin Talsma, Field Product Specialist at the Climate Corp.

“If I’m able to use a drone image or a satellite image that shows me biomass in a field I can use it to draw zones around the high and low areas and apply a fungicide only where I deem it as high risk.”

Assessing what the disease risk in different areas across a field has always been a difficult task, and it can be a painful experience for growers when they apply expensive products on areas that likely won’t benefit from it.

“If I’m only applying that fungicide to 70 percent of the acres in that field I’m saving cost on that product. This also helps with sustainability, I’m not using it where I don’t need it,” Talsma said.

He said growers can use historical field data, or through scouting weed species and populations, to create customized prescription zones for herbicides.

If there is a high and low rate for a herbicide, the higher rate can be targeted through this tool at areas with higher weed populations or at areas with weeds at a bigger growth stage.

This tool can also be used for harvest aids and desiccants.

“If I see areas that are greener, make those zones, apply that desiccant to those greener zones to help dry them out so I can put the entire field and crop through the combine at the same time,” Talsma said.

The satellite images provided by FieldView provide five to 10 metre resolution, which enables the company to create five zones.

Growers can always ground truth the zones before setting up their crop protection prescriptions.

To use the tool, growers will go to climateview.ca to pull up different maps their fields.

“If I want to look at a satellite image, or a previous year harvest image or seeding map showing me where I have different hybrids or varieties, I can put that in the background and draw using my mouse zones in that field and assign different rates.”

He said it’s very important that labelled rates are followed.

Once this script is created it can be uploaded via USB to the sprayer.

The new feature also works for insecticides and growth regulators.

This manual prescription tool for crop protection products is now part of the FieldView product, so growers who are already signed up can access this function immediately.

“If you want to look at FieldView and try it we have an offer where you can try it for up to a year for no charge. If you go to our website, climateview.ca there is more information on how to get started and take advantage of this trial,” Talsma said.

Farmers have to sign up for the trial offer by the end of August 2020.
