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 be on watch and take…
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 x63128, ahitchon@uoguelph.ca
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 millets (pearl, Japanese). Record acreages…
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 province. Some areas have excess…
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 Southern Ontario might also reach…
OMAFRA Field Crop Team July 13, 2013 1571 Comments Off on Harvest and Storage Strategies to Minimize Fusarium in 2013Helmut 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 year is no exception. How…
Tracey Baute July 12, 2013 1626 Comments Off on Soybean Aphid Populations Present and Increasing in Some FieldsReports 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 scouting weekly from now until…
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 with the skin, they cause…
July continues to be frustrating for those trying to make quality dry hay. Many areas continue to have had limited opportunities to make hay without rain-damage or heating. We are in a unique situation where there are considerable amounts of both first- and second-cut being made when weather conditions are suitable. Some rain-damaged hayfields have been blown back. First-cut hay…
by Joel Bagg, Forage Specialist, Jack Kyle, Pasture Specialist & Melanie Beech, OMAF and MRA Well managed horse pastures can contribute significant forage to the diet, while providing necessary horse health benefits, fulfilling the horse’s psychological need to graze, and minimizing the risk of poisonous weeds. Too often we see over-grazed horse pastures, filled with weeds and bare patches. A…
Our trap network has been up and running for nearly a month and surprisingly, trap counts have been very low so far. The lowest we have ever seen them for this time of year. We typically see moth catches peak the mid to second last week of July which means peak egg laying is usually shortly after that too but…
Mike Cowbrough July 2, 2013 17094 Comments Off on Herbicide Injury in Soybeans: 2013 SW Diagnostic DaysThe following 10 herbicide injury related scenarios where showcased at the 2013 South West Diagnostic Days held at the University of Guelph, Ridgetown Campus. These scenarios are either duplications of common mishaps that have occured in Ontario or a “look and see” based on farmer or agronomist query. It is important to point out that some of the scenarios shown…
Question: Once canola starts to bolt, do I need to be concerned about damage from Swede Midge. Answer: Yes. Canola is susceptible to significant damage up to secondary branch development. Once secondary branches begin to bud, canola is not subject to serious damage. The importance of secondary branches to yield depends on plant density. Under normal plant populations, canola will develop 3-5…
