It is proving to be another good insect year with several early season pests keeping everyone busy scouting to stay ahead of. Going into July and August, there are a few more pests that we need to keep watch for. Thrips continue to be spotted in soybeans, corn and wheat fields. There are several different […]
This was the last meeting of the Exeter, Mount Forest Breakfast meeting for this spring. Thanks to all those who attended and a special thanks to those who participated in the discussion. We will email a survey to the group at a later date to explore ideas of how the meetings should be conducted next […]
There is no surer sign of spring in the countryside than the evidence from our noses of manure application in full swing. Odour complaints occur every year, especially where urban settlements border livestock farms. Although manure odour is inconvenient, most farms do consider wind direction and make an effort to apply and incorporate manure […]
This article is written by Chris Gillard, University of Guelph – Ridgetown Anthracnose can cause severe yield and seed quality issues in dry beans. Anthracnose is managed in part with genetic resistance, clean seed and chemical seed treatments. Locally grown seed increases the risk of a disease outbreak, and growers are encouraged to use […]
Canola will dry down naturally and can be harvested directly without the application of pre-harvest herbicides. If the field is weedy or canola stems are green, there may be value in applying a pre-harvest herbicide. Pre-harvest herbicides may assist with dry down but will not hasten maturity. Follow all herbicide label specifications. Canola must be […]
Question: “Have a customer with a no-till rotation that has Nipplewort. A lot of it. We found some pretty decent options for most crops in the rotation to clean it up before planting, but he’s got some in his wheat this year too. What would be our best option to take a swing at it […]
Many management decisions affect hay quality. After deciding when to cut, the next big decision is about the moisture content. Accurately timing how long to let the crop wilt when harvesting a forage crop will help ensure that it stores well. It either needs to have enough moisture to ferment correctly (silage/haylage or baleage […]
Corn Stand Checkup Scouting corn between emergence and knee high provides a report card on seedbed preparation, planter operation and agronomic practices affecting early plant establishment and growth. Causes of issues can often be identified at this stage to make improvements for following years. Counting Plants For easy math, a common method of measuring population […]
The last meeting will be held on Wednesday, June 23rd at 8:00 am. Weather Conditions Dry conditions continued over the two weeks since the last meeting. Rainfall was patchy over the region, with some areas getting “just over an inch” and others nothing at all. Those that got rain reported crops continue to look good but could use more. Crops […]
Cereals Warm daytime and nighttime temperatures have resulted in rapid growth through the heading stage. Wheat can be vulnerable to hot temperatures during flowering especially if it gets above 33oC. Pollen viability can be affected at that temperature when the pollen is developing at 5-7 days before flowering. In the areas where it has been […]
Soybean aphids (SBA) have been reported in a few early planted soybean fields. But that doesn’t mean we need to panic. It has been a few years since we have had major aphid issues so it is good to review what the best management practices are. Especially given one of the main reasons we no […]
Corn Nitrogen Status Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration. Excess moisture can slow mineralization or increase the potential for losses through denitrification (especially under warm conditions) or leaching. Spring of 2021 progressed similar to 2020. Sunshine and little rainfall resulted in great soil conditions through April and […]
The European corn borer (ECB; Ostrinia nubilalis), has been an important pest of corn and other crops in eastern Canada for nearly a century now but is also known to be a sporadic pest in western Canada. Despite its name, ECB is actually a generalist feeder, having a wide range of hosts. Although corn is […]
Alfalfa weevil and potato leafhopper (PLH) are being reported as extremely high in many fields. Hot dry conditions have made it more favourable for these pests than their natural enemies (especially entomopathogenic fungi). Scout fields to determine if cutting is possible or if an insecticide application is necessary if thresholds are reached. Consider fields at […]
Summary Soil nitrogen supply (mineralization, loss) can be influenced by weather (soil temperature, moisture) each spring. OMAFRA leads an annual Pre Sidedress Nitrogen Test (PSNT) survey to gauge year-to-year levels across Ontario. PSNT soil samples were collected from 93 sites across Ontario from May 31st to June 2nd, 2021. The average PSNT value was 13 […]
