Tracey Baute August 18, 2017 3115 Comments Off on The Season is Not Over Yet for Late Season Pests Like Bean Leaf Beetle, Soybean Aphids and OthersDespite it being the middle of August, some pests are not showing signs of wrapping this season up. Bean leaf beetle are a particular concern in food grade IP and seed soybeans and edible beans across Ontario. As are pod piercing pests like stink bugs and tarnished plant bugs. Soybean aphids are also increasing in numbers, particularly in fields in…
OMAFRA Field Crop Team August 17, 2017 1919 Comments Off on Ontario Field Crop Report – August 17, 2017Parts of southwestern Ontario remain dry, while eastern Ontario continues to have frequent rainfall and saturated soils in many areas. While yields have been good, making dry hay continues to be a struggle for many growers under the later conditions. Winter wheat harvest has continued this past week in eastern Ontario. Most fields in the area have yielded between 70…
Tracey Baute August 11, 2017 2100 Comments Off on Western Bean Cutworm Still A Concern For Edible Beans & Late CornWe are still seeing WBC trap counts going up in most counties north and east of Perth. That means that WBC moth flight has not yet peaked in those counties. This is important because this also means that we haven’t reached peak egg laying in those counties and that there are a wack of moths flying around looking for somewhere…
OMAFRA Field Crop Team August 10, 2017 1961 Comments Off on ONTARIO FIELD CROP REPORT – August 10, 2017Western Bean Cutworm Update Western Bean Cutworm continues to be a concern for pollinating corn in areas with high trap counts. Peak moth flight has occurred in some of the counties in the southwest but counties east and north of Middlesex and those in Central and Eastern Ontario have not reached peak yet. Moths will now be looking for late…
Mike Cowbrough August 8, 2017 2538 Comments Off on Crop response to herbicides applied prior to and after emergence.For over 30 years, the Ontario Agriculture Weed’s team has competed in the Collegiate Weed Science Competition organized by the North Eastern Weed Science Society. In preparation for the “herbicide identification” portion of the competition, an area at the Elora Research Station is planted to a number of different crop and weed species and then sprayed with several herbicides. This training…
OMAFRA Field Crop Team August 3, 2017 2167 Comments Off on Ontario Field Crop Report – August 3, 2017Cover Crops The underseeded red clover is looking pretty good where the winter wheat has been harvested. As is often the case some fields have variable stands and others have poor or non-existent stands. If the red clover stand is poor and it is insured nothing can be done until it is released by Agricorp. If it is not insured…
General Another large hit of rainfall in eastern Ontario has put a stop to field work in the area again. Other parts of the province were slowed down by smaller amounts of rainfall over the weekend and overnight Thursday; however combining and hay harvest have started again. The two week forecast is showing some real opportunity to get field work…
Cereals Winter wheat harvest has begun throughout southwest Ontario but intermittent rainfall has caused delays. Some farmers in Essex County have finished harvest and initial word is that the quality and yield of the crop has been good. Harvest progress is likely 7-10 days behind what was observed in 2016 but comparable to the 2015 season. Post-harvest weed management A…
Nutrient Deficiencies in Soybeans Leaf yellowing and slow growth is evident in many fields. Stressful growing conditions will amplify nutrient deficiency symptoms, insect feeding, and disease symptoms. When plants are already stressed it’s even more important to manage deficiencies wherever possible. Fortunately, weather conditions over the next four to six weeks are more crucial to seed development than the first…
I’m seeing a lot of pics on Twitter of recent WBC moth catches in traps, which I think is great. The more people that are trapping, the more data we have to work with to determine when peak flight takes place and when scouting is required. But trap counts do not indicate if a spray is required in corn. There…
Western Bean Cutworm Western bean cutworm (WBC) traps have been set on corn and dry edible bean fields across southern Ontario, and low numbers of moths are being caught. Traps are used to monitor moth activity (Figure 1.) and indicate when scouting is required, and are not intended to determine when to spray insecticide. Up to date trap capture data…
Diagnosing Early Season Soybean Diseases In Ontario, soybean seedling diseases and root rots are the second most important yield limiting diseases (Figure 1.) and this year is no different. Cool soil temperatures along with early rains in parts of Essex and Niagara resulted in a large number of soybean fields needing to be replanted and the significant rainfall recently has…
Despite the wet weather, potato leafhoppers (PLH) are thriving in many areas of the province. Hopperburn is evident in the second crop of alfalfa, though dry bean fields are also at risk, especially once insecticide seed treatments are no longer present in the plants. Unfortunately, once hopperburn is noticed, yield and quality has already been compromised. Though PLH-resistant varieties of…
Nitrogen Rate Decisions for Corn Split nitrogen applications in corn not only minimize risk of loss, but can also provide an opportunity to adjust rates based on rainfall, which is a key factor in corn response to nitrogen from year to year. Use decision support tools to help with your rate decision and don’t underestimate the value of long-term management…
OMAFRA Field Crop Team June 21, 2017 1329 Comments Off on Mt. Forest Ag Breakfast Meeting Minutes – June 13, 20172017 Mt Forest Ag Breakfast Meeting Notes 2017-jun-13 General While still dealing with some impacts of wet and cooler conditions, almost all the crops are planted. Some areas may not get planted as persistent rains prevent that heavier ground from drying out. Consensus was that things looked way better than the previous meeting two weeks earlier. Beyond this region, there…
