Fall Means – Sampling for Soybean Cyst Nematode! As fall approaches, two things are certain – winter will come and soybean cyst nematode (SCN) has done its business! For many growers, managing soybean cyst nematode means planting SCN resistance varieties BUT effective SCN management does not end when you have selected your soybean varieties! It is imperative to not only…

Winter Wheat Winter wheat harvest is winding down across the province and reported yields to date have ranged from 80-130 bu/ac which compares well to the five-year average yield of 82.7 bushels/ac. This was a pleasant surprise for many growers’ considering all the stresses the winter wheat crop had to endure. Good reports of straw yield averaging 4000 pounds per…

Managing Fusarium Head Blight in the 2019 Winter Wheat Crop

The 2019 growing season has been a challenge for the winter wheat crop to say the least!  While many winter wheat fields have been removed, a significant amount of stands remain and are being kept through to harvest.  Given the wet conditions so far this spring and as we approach heading in many areas, it will be important to prepare…

Planting progress remains slow for all crops, and spray applications have also been significantly delayed by poor weather. Temperatures forecasted for early June are relatively cool, remaining around or below the 20°C mark in many regions.  Corn Corn planting progress at the end of May was estimated to be less than 50% complete. In some regions, corn planting at the…

DON in corn silage

Corn

In properly ensiled corn silage, research has not shown an increase in mycotoxins from levels in the crop at harvest. Fusarium species, the fungi that produce DON, do not like low oxygen, low pH environments, so if corn goes through the proper ensiling process fusarium should no longer be active and able to produce DON. It takes at least three…

Destroying a Corn Crop at Harvest Time

Corn

While growers are encouraged to find all avenues possible to clean or market their corn, with elevated ear moulds in the 2018 Ontario corn crop, there may be fields with DON levels that render the crop unmarketable. These fields will require destruction in preparation for the 2019 crop season. Destroying a corn crop at harvest will present challenges for 2019,…

End Uses for Mouldy Corn in 2018 Harvesting is of course the preferred option but for some producers finding a market for mouldy or corn with high levels of DON content can be difficult this year as well as it takes time to find alternative uses or streams for this corn. Livestock producers, especially those with hogs, cannot feed high…

STORAGE TIPS FOR MOULDY CORN!

Corn

STORAGE TIPS FOR MOULDY CORN! 1. Harvest infected fields early, and dry corn as soon as possible after harvesting. Do not store wet grain overnight in trucks, wagons, or bins. 2. Dry corn using high-temperature drying, to 15% moisture or less. This stops mould growth and mycotoxin production, but does not reduce mycotoxins already present. Low-temperature drying takes much longer,…

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 are advised that the same…

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

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…
