SYNOPSIS Majority of edible beans are in late vegetative to early flowering. The crop in many areas looks excellent. Recent heavy rains and saturated soils raises the risk of white mould, anthracnose in white and black beans and root rot. Leafhopper populations have been low up to now. White Mould : Fungicides to protect against […]
This spring’s challenging planting conditions has resulted in quite a few of uneven canola stands with both reduced populations and delayed emergence. This has some growers weighing the merits of applying a fungicide this season. Sclerotinia incidence varies greatly between fields and years thus making routine spraying of fungicide unprofitable. However when the risk of […]
Author: Jocelyn Smith, University of Guelph, Ridgetown Campus Growers in the high WBC risk areas (sandy soils) saw heavy infestations of WBC in 2013 and many were surprised by the survival and amount of damage by WBC on Bt corn. Bt corn hybrids that express the Cry 1F insecticidal protein such as the Herculex® and […]
Some first-cut horse hay is still to be made while many will start second-cut dairy haylage soon. Harvest schedules are delayed behind normal, especially in western Ontario. This may make taking a fourth-cut more difficult. Hay making weather has generally been good, but some hay has been rain-damaged. Yields have been extremely variable, depending on […]
Italian ryegrass can produce very high quality, leafy, palatable forage suitable for high producing dairy cows. As a cool-season bunch grass, it is best adapted to cool, moist conditions. It does not grow as well in hot, dry summer weather. In Ontario it has been seeded in early spring (April, early-May) for harvesting that year. […]
First-cut haying continues while some 2nd cut dairy haylage will start soon. Hay making weather was generally good in early June, but some more recent storms have rain-damaged some hay. Rains will help 2nd cut regrowth. Yields have been quite variable, ranging from good in eastern Ontario to some winter injured areas in western Ontario […]
First-cut continues with variable yields. Yields are generally good in eastern Ontario. In western Ontario areas where alfalfa winterkill and injury occurred, stands are thin, with many reported yields at 50 – 80% of normal. This has created some concern about producing adequate forage supplies. Considerable acres have been seeded to annual forages such as […]
Greg Stewart, Peter Johnson and Ian McDonald, OMAF & MRA Background In 2014 the OMAF & MRA field crops team once again surveyed a range of corn fields to determine the impact that this springs weather has had on the level of residual soil nitrate. This year April was cool with less growth than […]
Conditions: Crop Heat Units from the May 1st are right about the 30 year normal. Winter wheat: In the case of highly uneven fields, spraying is recommended when about 25% of heads are emerged for 5 days (and head past ligule). The idea is that the first 25% are probably the better heads anyways and […]
The next meeting will be held at the Huron Research Station. Breakfast will be provided at 7 am. There will be a short tour (1 hour). Please bring any suggestions for future research that should be conducted. Synopsis: Considerable field work was possible over the weekend and Monday, especially further south where they were further […]
The recent registration of Permit (active ingredient: halosulfuron) in Ontario provides a nice tool for the management of yellow nutsedge in corn. Permit will also provide residual control of certain broadleaf weeds. For those two reasons, many growers will consider tank-mixing glyphosate and Permit for use in glyphosate tolerant corn. Here are 5 key points to consider when […]
With some dry weather and delayed alfalfa maturity, some high quality 1st-cut hay, haylage and baleage has been made. Yields are quite variable, with some very disappointing yields being reported in western Ontario, but closer to normal yields in the east. Sulphur Deficiency Some alfalfa is showing the sympton of uniform yellowing, indicating sulphur […]
Low levels of armyworm, cereal leaf beetles and grass sawflies have been spotted in various wheat fields over the last week. Scout to make sure these don’t get out of hand. With any of these, protecting the flag leaf is most important. Armyworm and grass sawflies clip the wheat head off too. Armyworm feed at […]
May 1 to June 4Norfolk/Haldimand/Niagara 2014 2013 Rainfall + 120 mm + 85 mm Crop Heat Units ~ 440 ~ 520 Growing Degree Days ~ 295 ~335 Some field work on the weekend ended with another dose of precipitation June 2. Highly variable, most areas received between 5 and 25 mm; with the lower amounts […]
Synopsis: Finally significant planting progress in corn and soybeans! Rainfall over the last two weeks varied from 0.5” to 3”. Early corn is at 4 to 5 leaf stage while the majority of the corn is emerging to 2 leaves. The most advanced wheat is heading. Weed control is becoming the order of the day. […]
