When is my canola in the right stage for a fungicide?

When is my canola in the right stage for a fungicide?

Q & A with Nutrien Ag Solutions

Q: How do I determine the correct bloom stage in canola to apply a sclerotinia fungicide? A: Proper timing of fungicide for sclerotinia control requires regular scouting. The recommended timing is application at the 30 per cent bloom stage. Application prior to this stage can result in reduced control as petals susceptible to infection have yet to emerge. […] Read more

Should I treat my seed with a fungicide?

Should I treat my seed with a fungicide?

Q & A with Nutrien Ag Solutions

Q: Why should I treat my seed with a fungicide? When should my seed treatment include an insecticide? A: Seeds and seedlings are vulnerable to many soil-borne and foliar pests. Insects and pathogens can destroy germinating seeds and young plants, which are relatively tender and lack food reserves to recover from injuries or to survive […] Read more

Pearce: Multiple modes of action an emerging reality for fungicides

As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more

UPL to buy crop chem firm Arysta

Indian chemical manufacturer UPL has raised the financial backing for an all-cash deal to become what’s expected to be the world’s fifth biggest crop chemical firm. UPL on July 20 announced it will pay $4.2 billion to buy 100 per cent of Arysta LifeScience — the maker of Everest and Inferno herbicides, among other products […] Read more



Bayer’s Zone Spray is currently set up to help target sclerotinia in canola, but there are plans to incorporate other crop and disease combinations in the future.

Bayer Digital Farming launches Zone Spray

This new cloud-based program helps farmers spray only the right acres

This summer, canola growers will likely again be faced with the tough decision of whether or not to spray fields with a fungicide to protect the crop from sclerotinia. Spraying unnecessarily can mean wasted inputs, but failing to protect crops when needed could also mean significant yield losses. Even if producers decide to spray fungicide, […] Read more

FHB: a disease of even-numbered years

It seems unlikely that FHB strikes every second year, but the data backs it up

This is an update of a piece about fusarium head blight (FHB) we did about one year ago now. To be honest, much of it is actually “cut and paste” from last year. I’ve never done that before, but it seems appropriate for this situation. We are just adding another year of data. In agronomy […] Read more

Honeybees’ attraction to fungicide ‘unsettling’

London | Thomson Reuters Foundation — Honeybees are attracted to a fungicide used in agriculture with “unsettling implications” for global food production, a U.S. scientist said on Tuesday. Tests carried out by a team from the University of Illinois showed bees preferred to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone. […] Read more

U.S. study links bumblebee declines to fungicide use

A new look at the environmental factors around declining bumblebee populations and ranges points to a less-than-usual suspect: fungicides. “Insecticides work; they kill insects. Fungicides have been largely overlooked because they are not targeted for insects, but fungicides may not be quite as benign — toward bumblebees — as we once thought,” Scott McArt, assistant […] Read more
