This article was written by Dave Hooker and Albert Tenuta, on behalf of the Ontario Corn Committee Purpose Although 2018 was very challenging to growers and the rest of the corn industry, it presented an opportunity to compare hybrids for DON accumulation across several locations of the Ontario Corn Performance Trials. The main purpose […]
This article was written by Ben Rosser, OMAFRA Corn Specialist, and James Dyck, OMAFRA Engineer- Field Crop Conditioning & Environment A number of growers cleaned corn this fall in efforts to reduce DON. Whether it is on the combine or at the bins, the general message is to remove as much fines or cob as possible as […]
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 […]
Co-Authored with Albert Tenuta, Field Crop Pathologist, OMAFRA OMAFRA field crop staff with the assistance from members of the Ontario Agri-Business Association (OABA) have completed the annual Provincial corn ear mould and mycotoxin survey. These mycotoxins, particularly vomitoxin (DON) produced primarily by Gibberella/Fusarium ear moulds can be disruptive when fed to livestock, especially hogs. The […]

On this week’s episode Mike summarizes the results of a three year project coordinated by Scott Banks in association with the Lanark and Renfrew Soil and Crop Improvement Association. The objective of the study was to evaluate how well a fungicide called “Proline” was at reducing vomitoxin […]
Greg Stewart, OMAFRA Corn Specialist Albert Tenuta, OMAFRA Field Crop Pathologist The OMAFRA Field Crops team has completed the survey of the 2014 Ontario corn crop to determine ear mould incidence and the occurrence of mycotoxins in the grain. These mycotoxins, particularly vomitoxin (DON) produced primarily by Gibberella/Fusarium ear moulds, are grading factors and can […]
Co-Authored by: Albert Tenuta, OMAF & MRA Field Crop Pathologist The OMAF and MRA Field Crops team has recently completed a survey of the 2013 Ontario corn crop to determine ear mould incidence as well as the occurrence of mycotoxins in the grain. These mycotoxins, particularly vomitoxin (DON) produced primarily by Gibberella/Fusarium ear moulds can […]
Co-Author: Albert Tenuta, OMAFRA Field Crop Pathologist The annual corn ear mould and vomitoxin survey by the OMAFRA Field Crops team indicates that the 2012 Ontario corn crop is distinctly low in ear moulds and vomitoxin. However, stakeholders are reminded that individual field conditions (environmental, hybrid, tillage, rotation, etc.) are important in ear mould and […]
Co-Authored by: Albert Tenuta In the past several weeks increased attention has been given to the potential for ear moulds in the 2011 corn crop and the mycotoxins potentially associated with these moulds. These mycotoxins, particularly the vomitoxin (DON) can be disruptive when fed to livestock, especially hogs. To increase our understanding of the situation […]
