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 […]
When grubs hit hard, forage supplies dwindle fast! Stand loss in hay fields and pastures due to grub damage is becoming more common. Warm open falls and warm springs are ideal for grub feeding activity. (Figure 1) The result is a thin, weedy stand with low yields , and poor resistance to drought. Grubs prefer […]
Discussion: From mid-April to mid-May, eastern Ontario accumulated 200 to 250 CHUs. Since May 1st, the area has accumulated 150 to 200 CHUs. Cereals Planting is virtually complete. Stands look good overall, but dry conditions at planting time/variable planting depth is resulting in some stand unevenness. Early seeded fields are at the 4 leaf stage […]
Fifty to sixty per cent of the crop is now seeded. Some producers are finished. Very early planted beans have emerged. Under cool conditions it can take 30 days for beans to emerge. In warm temperatures beans can emerge in 4 to 7 days. Crusting has been a problem in a few areas, but not […]
The warmer temperatures this week have made for faster grass growth. Using a quick rotation to graze all paddocks before the grass becomes mature is important. In a rotational system look to the last paddock in the rotation and adjust the rotation speed to arrive at the last paddock when it is at the right […]
Corn planting is 95 % complete across the province. Emergence is good to excellent in most areas with the majority of the corn in the 1-3 leaf stage. Weed control should be the priority as the crop approaches the critical 3-4 leaf stage. Cutworm injury has been reported in some areas south of London. Scout fields […]
Winter cereals are far ahead of normal development. Rye and barley are in full head, advanced wheat fields are at head emergence. Combines need to be ready to harvest two weeks earlier than ever before. Dry weather and low fusarium risk has some growers questioning the need for fusarium control. Remember that the fusarium fungicides Caramba […]
Early planted canola is at 1-2 leaf and later April planted canola is cotyledon to 1 leaf stage. Heavy rains in several areas resulted in crusting and emergence issues. Flea beetle pressure is high in some areas. Populations are highest in field borders. Scout emerged canola for flea beetles up to 4 leaf stage. Threshold […]
