Co-author Ken Janovicek, University of Guelph. Background The OMAFRA field crop unit in collaboration with farm cooperators, agribusiness and SGS-AgriFood Labs conducted the annual survey of soil nitrate nitrogen levels across the province from June 3rd to June 5th, sampling over 130 fields. The samples were collected after heavy rainfall events during the weekend of May 30-31, where […]
With recent storms and heavy rains this week, haying has been placed on hold. Yields are quite variable, with some very disappointing yields being reported in western and central Ontario (60 – 100% of normal). Yields are closer to normal (85- 100%) in eastern Ontario. Dry weather in late-April and May limited forage growth and yield […]
Fusarium head blight continues to be of significant economic concern in Ontario as well as other provinces. Although new tools have helped, it is not realistic to expect a single cultural or management practice to effectively manage this devastating disease alone. The integration of the various cultural or management practices (“tools”) into a coordinated FHB […]
Willson Hall, University of Guelph, Ridgetown Campus, 120 Main St. East. Ridgetown. This week’s Breakfast courtesy of BASF Canada, thank you. Synopsis: Dry conditions in many parts of the area have been alleviated with the rains over the past week especially the weekend. The rain was welcome with much of the area receiving 1.5” to […]
First-cut dairy haylage is in full swing as the weather permits. Some farms are finished. The dry spring weather limited forage growth in some areas, particularly grassier fields, forage winter cereals, ryegrass, and alfalfa fields that were older, winter injured or fall harvested. Where severe frost occured on May 23rd, some alfalfa growth and development […]
Synopsis: Rainfall amounts over last weekend across region varied from 0.25″ in lakeshore areas to 2.5 – 3″ in Tavistock-Guelph area. See map of areas affected by frost on fieldcropnews- Extent of Cold Temperature map. May 23rd frost was widespread and caused more damage than originally estimated. Need to remind growers to get out and check all […]
Much of the province received welcome showers over the weekend. A few areas were hit with heavy rains that caused flooding in low lying areas. In most cases water drained away quickly but standing water could still be found in some fields two days after the rain. See picture #1. Flooded soybeans on June 1st, […]
Two pests that are starting to appear in Ontario fields include cereal leaf beetle and alfalfa weevil. Cereal leaf beetle: Both adults and larvae can cause damage by chewing long strips of tissue between the leaf veins, though most of the damage is done by the larvae in June. The larvae look somewhat like slugs […]
Chair for this meeting was Jeremy O’Shea. Chair for next meeting is Joanna Wallace. Thanks to BASF for sponsoring breakfast. Synopsis: Frost across many parts of the province has caused significant damage. Muck soils, sandy soils, and lower elevations were the worst hit. The vast majority of corn will recover since the growing point is still […]
First-cut dairy haylage is started in southern Ontario, and should be in full swing next week. With the dry weather in late-April and May in many areas, forage growth is reduced, particularly in the grasses. Potential yields are quite variable depending on the stand, but looks disappointing in some areas. Grassier fields, forage winter cereals, ryegrass, and alfalfa […]
The early start to the corn season came to an abrupt halt in parts of Ontario on May 23rd when temperatures dipped to -3oC in parts of the province. It is always painfull to see corn seedlings flat on the ground (Figure 1.). However, with corn mostly at the spike to 4 leaf stage when […]
Over-night temperatures on May 22 to 23 dipped to -2 to -3 oC in many parts of Ontario. Cereal crops are hardy to light frosts. Leaf tissue on plants that have not hardened off will withstand temperatures of -4 oC or lower before the cells will freeze and damage occurs, making late spring frosts of […]
Synopsis: Corn planting is virtually complete and soybean planting is between 75 to 80% complete. Earliest planted wheat is at flag leaf stage, while rye is heading. Frost last week did not have any significant impact for field crops. Growers are finding it challenging to keep up with weed control and many planned pre-emerge programs […]
Synopsis: A tremendous amount of field work has taken place over the past couple of weeks. Corn planting is 90-95% complete, soybean planting is 70% complete. Corn emergence has been good. Soil conditions and moisture up to now have been excellent. Concern now is planting into dry soil conditions and need to plant deeper,. Many […]
Some US states to our south have been reporting high numbers of black cutworm moths in their pheromone traps and are starting to see some black cutworm injury in newly emerging corn fields. These moths are carried into Ontario via storm fronts. Once they arrive the adult moths look for weedy patches in fields to […]
