HARVEST TIPS FOR MOULDY CORN! 1. Prioritize your corn harvest and storage. Do not mix old crop (2017) or low DON corn with potentially mouldy corn from this harvest. Livestock producers, especially hog, will want to scout fields, sample and test for mycotoxins in order to store their cleanest corn for feeding purposes. Cash croppers […]

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 […]
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 […]
Application of fusarium control fungicides requires specialized nozzles or nozzle combinations to achieve optimum results. Maximizing wheat head coverage requires both proper timing and the best nozzle configurations. Maximize Spray Coverage of Wheat Heads The key to applying fungicides to prevent fusarium head blight (FHB) is to spray all sides of all wheat heads with […]
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 […]
