Ontario wheat performance trials are the first to add fungicides as part of the evaluation package. Years ago, no one sprayed wheat, barely even with a herbicide. Today, if you don’t spray a fusarium fungicide on your wheat crop, you aren’t a real wheat farmer. And the fusarium issues with #Harvest13 have really driven this […]
The weather has been ideal for soybean aphids and has been dry enough in areas to also see mites starting up. Some fields are starting to see one or both of these pests increasing in numbers. Here is just a reminder of important things to consider when assessing fields: Soybean Aphids – The threshold of […]
While it is always very tempting to cut some alfalfa in the fall, the decision should weigh the immediate need for forage against the increased risk of alfalfa winterkill and reduced yields next spring. The Critical Fall Harvest Period for alfalfa is the 6-week period preceeding the average date of killing frost. Not cutting […]
By Brian Hall, OMAF/MRA, Stratford For many growers, this year’s canola crop will be a challenge to harvest as a result of large differences in crop stage, because of thin and weedy stands, or fields that were damaged by swede midge. When managing these fields, harvest management either by swathing or direct harvest becomes critical […]
The window for summer seeding alfalfa and alfalfa-grass mixtures is approaching for much of the province. This can be a good way to establish new fields so that full season yields can be harvested next year. It is typically done after winter wheat or spring cereals are harvested, and also during years when alfalfa winterkill […]
by Brian Hall The summer emergence of flea beetles is upon us. In July larvae emerge from the soil and begin to feed on canola pods and leaves. Feeding during pod development can cause premature pod ripening, shrivelled seeds, pod shatter and allow fungal growth during wet weather. In most cases, although the damage can […]
Learn about the natural enemies of crop pests, from predators to parasites to pathogens. What do they do? How can you find and identify them? How can you protect them and encourage them to be active in your field? Wednesday, August 7 1:00-4:30 pm Simcoe OMAF and MRA Auditorium, Blueline Road, Simcoe, Ontario The workshop […]
Soybean aphids – Eastern Ontario and the thumb of Michigan have been battling soybean aphids for some time now. This is ideal weather for them so I expect to start to see fields in SW ON noticing populations climb. That said, I have not given up on the natural enemies. I just want everyone to […]
Researchers at the University of Guelph are looking for fields with high numbers of corn rootworm beetles. Beetles will be used for resistance monitoring for Bt traits in corn. If you have unexpected rootworm damage, or a large population of adult beetles please contact: Jocelyn Smith: 519-674-1500 x63551, jocelyn.smith@uoguelph.ca Tracey Baute: 519-674-1696, tracey.baute@ontario.ca Andrea Hitchon: 519-674-1500 […]
by Joel Bagg, Forage Specialist & Peter Johnson, Cereals Specialist, OMAF and MRA Summer seeding annual forages can be a useful low-cost option for producing extra feed, either as an emergency forage or a regular double-crop option. These forages include cool-season cereals (oats, barley, triticale) and cereal-pea mixtures, as well as warm-season sorghums, sorghum-sudangrass and […]
Good haying weather returned July 11th, with lots of first and second-cut being made. Considerably more baleage was made and more propionate hay preservative was used this year. There is some concern about hay that is heating in storage. (Refer to “Silo and Hay Mow Fires” at www.omafra.gov.on.ca/english/engineer/facts/93-025.htm.) Yields have been quite variable across the […]
My crew is finding many corn fields at threshold levels of western bean cutworm (WBC) in the “high risk areas” of Bothwell and Tillsonburg. We have learned over the last few years that Bothwell and areas around Tillsonburg in particular (higher sandy soil areas) are prone to high levels of WBC infestations. Other areas of […]
Helmut Spieser, Agricultural Engineer, OMAF Ridgetown Peter Johnson, Cereal Specialist, OMAF, Stratford Albert Tenuta, Field Crop Pathologist, OMAF, Ridgetown Weather conditions in 2013 have been ideal for Fusarium Head Blight development in areas of Ontario and surrounding US states. Every year we deal with or try to minimize Fusarium impact on the crop and this […]
Reports of fields in Eastern/Central Ontario with threshold levels of soybean aphids have been coming in this week. Chris DiFonzo, MSU has also alerted us to very high numbers showing up in Michigan, especially in the thumb which could migrate here into Ontario via any future storm fronts. It is very important to be out […]
Wild parsnip is a common weed in eastern Ontario, and is spreading in many other parts of the province. It is a biennial, or short-lived perennial (Figure 1). While wild parsnip does not have the notoriety of giant hogweed, its sap does contain some of the same chemicals (furanocoumarins). When these compounds come in contact […]
