Good Mycotoxin Test Begins With A “Representative” Sample!

Corn

Good Mycotoxin Test Begins With A “Representative” Sample! The importance of collecting a “representative” sample cannot be overestimated. The most significant variable associated with mycotoxin test results comes from incorrect sample collection or uneven distribution of infected kernels in load (Figure 1). Although taking a sample from the top of a storage bin, truck or combine may be easy and…

Effectively Managing Stripe Rust

Joanna FollingsJoanna Follings December 6, 2017 3091 Comments Off on Effectively Managing Stripe Rust
Diseases

Co-authored with Albert Tenuta, Pathologist, Field Crops In 2016 the milder winter conditions resulted in early leaf and stripe rust infections in Tennessee and Kentucky. This resulted in rust spores being blown into Ontario earlier than we typically see. By mid-May 2016, stripe rust was prevalent in most areas of southwestern Ontario. Growers who selected tolerant varieties or applied a…

Integrated Fusarium head blight management: Employing all the tools

Albert TenutaAlbert Tenuta June 10, 2015 2190 Comments Off on Integrated Fusarium head blight management: Employing all the tools
Diseases

Fusarium head blight continues to be of significant economic concern in Ontario as well as other provinces. Although new tools have helped, it is not realistic to expect a single cultural or management practice to effectively manage this devastating disease alone. The integration of the various cultural or management practices (“tools”) into a coordinated FHB management program can minimize producer…

Diseases

Root rot is  becoming visually evident in many edible bean fields now that beans are entering  a more rapid vegetative growth phase and will have a high demand for water and nutrients. Pounding rains, compaction, tillage pans, poor internal drainage and soil structure are common culprits for inducing root rot. Common visual symptoms include stunting and uneven growth, yellowing of…

Should You Apply a Fungicide for Sclerotinia in Canola

Brian HallBrian Hall July 10, 2014 3463 Comments Off on Should You Apply a Fungicide for Sclerotinia in Canola
Canola

This spring’s challenging planting conditions has resulted in quite a few of uneven canola stands with both reduced  populations and delayed emergence. This has  some growers weighing the merits of applying a fungicide this season.  Sclerotinia incidence varies greatly between fields and years thus making routine spraying of fungicide unprofitable. However when the risk of sclerotinia is high, applying a…
