Haylage started in full swing on May 21st in some areas. Yields are very disappointing, with two-thirds of a normal yield or less being reported. Some alfalfa fields severely damage by winterkill and disease are being harvested early and planted into corn for silage. Planting as soon as possible and adequate moisture are essential to […]
The weather is certainly warming up and it looks like the forecast is for more of the same. Things are getting busy and I’ve got a few things to talk about this week. The first is the start of the Western Bean Cutworm Trapping network. Traps should be set up this week and the data […]
Synopsis: Wheat is advancing quickly and many fields at flag leaf stage. Disease pressure is low in most wheat fields. Corn planting is 75%-100% complete. Soybeans are 50-80% planted. Heavy rains and soil crusting in Arthur-Orangeville-Shelburne area has resulted in some replanting of corn and canola. Edible bean planting has started. Corn: Increased use of pre-emerge herbicide […]
In any given year, as much as 32,000 acres of Ontario corn is re-planted due to uneconomical plant stands. A two year study conducted at the University of Guelph demonstrated that either Assure II + Sure Mix, Excel Super or Select + Amigo could be applied the day before replanting corn to effectively control a […]
Application of manure from animals infected with pathogens is a potential method for spreading infection. This becomes a higher risk when the manure is applied to crops used for animal consumption. Johne’s (yo-nees) Disease is a persistent and debilitating bacterial disease that affects the intestines of ruminant animals, including cattle, goats and sheep. The disease […]
If you are unhappy with your stand of corn and think you may wish to replant, download the Ontario Corn Replant Calculator to assist you in this important decision. Many thanks to Dr. Dave Hooker and Ken Janovicek (Plant Agriculture Department, University of Guelph) for their efforts in putting this tool together. DOWNLOAD: THE ONTARIO […]
Updated – May 27, 2020 There are several species of aphids that are grouped together as “cereal aphids”. The most common are bird cherry oat aphids (Figure 1) and corn leaf aphids (Figure 2), though English grain aphid and greenbugs can sometimes be found. The aphids would have been present since the fall and usually […]
Application of fusarium control fungicides requires specialized nozzles or nozzle combinations to achieve optimum results. Maximizing wheat head coverage requires both proper timing and the best nozzle configurations. Maximize Spray Coverage of Wheat Heads The key to applying fungicides to prevent fusarium head blight (FHB) is to spray all sides of all wheat heads with […]
Soybean planting is essentially finished. Eastern Ontario is about 90 percent complete and some clay soils still need to be seeded. This has been one of the earliest planting seasons in recent memory. In the southwest some areas have been so dry that seed had to be placed over two inches deep to find moisture. […]
Corn planting is essentially complete across Ontario other then a small amount of replanting due to emergence/stand issues or where corn is following first cut alfalfa. Use the Replant Decision Aid posted at www.gocorn.net if considering this where stands are thin. Start with accurate plant counts of the current stand and consider all the replanting economics (crop […]
Winter wheat is heading rapidly. Wheat west of London will be ready for fusarium sprays by the weekend, with the crop north and east following closely. Stripe rust and high aphid numbers have been found in Chatham-Kent. Scout! Threshold is 50 aphids/stem after heading. Barley yellow dwarf virus (BYDV) symptoms are showing at surprising levels […]
Planting has started with 10 percent in. Soil conditions have been excellent with good soil moisture. Field trials have generally not shown economic response to nitrogen, although applying a small amount of N (30-40 lb/ac) encourages rapid vegetative growth, canopy closure and stimulates root growth which can aid in overcoming stress caused by root rot […]
Planting is complete in most areas. April planted canola is at 2-4 leaf stage and advancing rapidly. Plant populations are fair to average (4-8 plants/ft2) with some replanting due to weather related stress and flea beetles. Flea beetle pressure is high in most areas. Sprays have no residual control so scout several days later to […]
Included: Stripe rust in wheat, fusarium control (to do or not to do), aphids above threshold (wheat), corn replants and adding to thin stands, bugs in bins and more. Synopsis: Spotty rainfall across the region, from almost nil to 3″+. Many “last 50 acres” switched from corn into soy with price rally. Limited replant corn and soy […]
Forage yield expectations are variable, but well below normal in many areas. Alfalfa fields severely damage by winterkill and disease are being harvested early and planted into corn for silage. (Planting Corn Silage After Early Haylage Harvest www.omafra.gov.on.ca/english/crops/field/forages/corn_earlyhay.htm) Planning to summer seed alfalfa following winter wheat is an option for those that have experienced significant […]
