Scouts and agronomists may put biosecurity measures in place with a certain disease or crop in mind, but should ensure protocols are in place each and every time you walk fields. Crops are grown in rotation, so the soil in corn fields may contain soybean cyst nematode and soil in wheat fields may contain clubroot […]
Winter wheat fields are experiencing snow mould in regions that had significant snow coverage and included but are not limited to Bruce, Grey, Huron, Perth and Wellington counties. Those fields effected were generally planted early and had lots of top growth. There are also varietal differences with more susceptible varieties showing more severe symptoms. When […]
Photo: Scouting a few days after a spring frost is a good way to assess the severity of any damage. Good agronomy is very important for achieving good yield and quality in forage crops. While good agronomy includes a fertility plan, seeding techniques, and harvest management, it also relies on proactive decision-making. The only way […]
Reports are coming in about insect pressure in forage crops and pastures across the province. Central and eastern Ontario currently have high potato leafhopper pressure, while districts across northern Ontario are challenged by armyworms. The only way to know if a field has insect pressure is to scout it! More information about scouting forage crops […]
Scouting is an important part of growing quality forage. Just like other field crops, scouting alfalfa helps growers stay ahead of emerging problems, correctly time harvests, and make better decisions when planning future crops. Plant counts should be done spring and fall (Table 1). These can be done when the alfalfa is dormant. The spring […]
I have been hearing reports of soybean aphids starting to pop up on non-Cruiser soybeans in Ontario. It has been a few years since we’ve had to deal with them so I thought a refresher might be in order. Soybean aphids initially start to colonize in pockets of early planted fields. Several plants in these […]
Last summer, potato leafhopper (PLH) certainly lived up to its reputation as the most damaging alfalfa insect pest in Ontario. In many parts of the province, PLH feeding resulted in yield loses of over 1 tonne of alfalfa per acre or roughly a loss of $200/acre. While PLH damage was far greater than normal, it […]
