Resistance management is of utmost importance for cucurbit downy mildew
Changes in fungicide regulations have reduced the available treatments
Reading Time: 3 minutes Management of cucurbit downy mildew (CDM) requires more diligence with limited fungicide options. Recent changes in fungicide regulations leaves fewer options for farmers to control CDM, economically the most important disease for cucumbers. Why it matters: Re-evaluation of chlorothalonil has reduced the number of applications for cucurbit growers from seven to two. CDM has become […] Read more
Digital supercluster backs precision fungicide development
Project aims at wheat leaf rust, reducing pesticide load
Reading Time: 3 minutes A West Coast ag tech company in the crop pest control business is setting its sights on wheat leaf rust, with support from one of Canada’s five research superclusters — but not the cluster you might expect. Out of the five federally-supported superclusters launched in early 2018, Protein Industries Canada has been most closely linked […] Read more
Making better spraying decisions with low-cost, early fungal disease detection
Spornado is being tested across Canada, especially in higher value vegetable crops
Reading Time: 3 minutes It was a call from a client looking for a low-tech method for early detection of a fungal disease in potatoes that charted a new course for Toronto microbiology lab Sporometrics. The resulting innovation, Spornado Sampler, has been called the first reliable, early alert system for fungal crop diseases that’s available to farmers at an […] Read more
New fungicide launched for fusarium head blight control
Syngenta’s Group 7 ADEPIDYN to be released to all crop markets in 2020
Reading Time: 2 minutes Syngenta’s new active fungicide ingredient ADEPIDYN is registered in Canada and will be released nationwide under the Miravis portfolio in 2020. The company says the molecule is a Group 7 carboxamide fungicide with a succinate hydrogenase inhibitor (SDHI) mode of action bringing “power, spectrum and stamina” to the table for growers across the country wanting […] Read more
Trial aims to better detect late blight pathogen before it infects tomatoes
The three-year project will evaluate early detection, management approaches and potential benefits
Reading Time: 3 minutes A new three-year project is in place at the University of Guelph, Ridgetown Campus, to help detect late blight pathogen presence in the air before it infests tomatoes, allowing for better control management. There is currently no method to detect the presence of the phytophthora infestans, making it difficult for growers properly manage late blight, […] Read more
Bee-based disease prevention
Inoculating flowering plants with insect-delivered fungus can help limit disease
Reading Time: 4 minutes Fungi that can inoculate crops against disease can be applied using insects — bumblebees, to be specific. According to Bee Vectoring Technology (BVT) — a Canadian company with offices in the United States and Europe, and in the process of commercializing such a service — Bombus-delivered inoculants offer fruit farmers another way to augment their […] Read more
Sprayer power: Is electricity the next big thing in spray adjuvants?
Positively charging spray droplets can help them stick to plants, but droplets need to be small
Reading Time: 3 minutes Getting fungicides and insecticides into the canopy and to the underside of leaves is a challenge for most sprayers. Small droplet sizes and even coverage are needed for this and for the fungicide lacquering required for control in most non-systemic products; and that comes with the risk of drift. Why it matters: With more precise […] Read more
