Low forage inventories, high land costs, and sometimes increasing risks for alfalfa winterkill make assessing spring alfalfa health essential. Walking fields in early spring to determine if the alfalfa stand has thinned, and assessing if plants are dead or unhealthy is a proactive strategy to determine management options. Making the decision whether to manage an existing reduced stand or replace it […]
How do you control chickweed in alfalfa? It is a question asked annually. If you don’t know what chickweed is search it on google images. Of course there is always www.weedinfo.ca. There are three main points on chickweed infesting an alfalfa crop that I have learned over the years. Any herbicide that is effective at controlling chickweed […]
Orchardgrass can be very productive, particularly in pastures and hay fields with aggressive cutting schedules. It is a very fast growing, perennial, cool-season grass. However, because it heads so very early in the spring and then declines quickly in digestible energy and protein, it has not been as widely used for stored forage in […]
Frost seeding or the broadcasting of forage seed on frozen ground in late-winter or early-spring can be an effective way of improving the forage quality and yield of thinning pastures. It allows for the establishment of forages at reduced cost in an undisturbed sod and also shortens the non-grazing period in the spring. For frost […]
Written by: Tracey Baute – Field Crop Entomologist and Greg Stewart – Corn Specialist, Ministry of Agriculture and Food and Ministry of Rural Affairs A high level of concern was raised last spring regarding bee kills and corn planting. Many growers are asking what actions they can take to help reduce the risk of bee […]
Many horse owners are finding it increasingly challenging to find and purchase suitable hay at a price they can afford. Low hay yields due to dry weather in 2012 were followed by poorer quality as a result of rainy haying weather in 2013. However, there are also long term economic factors in play that […]
Manure Injection – New technology = More Options The goal: To increase the opportunities for injecting manure into a variety of growing crops with nutrient placement as similar to commercial fertilizer placement as possible. Traditional manure injection combined manure application with primary or secondary tillage gives the benefit of full disturbance of the soil profile […]
It seems to be an annual question. Do I add ammonium sulfate (AMS) to glyphosate? Will it improve weed control especially if my water source is hard? The short answer is no. Skeptical? I understand. There are many areas within the United States that insist the addition of ammonium sulfate (AMS) to glyphosate is critical, […]
Last summer, potato leafhopper (PLH) certainly lived up to its reputation as the most damaging alfalfa insect pest in Ontario. In many parts of the province, PLH feeding resulted in yield loses of over 1 tonne of alfalfa per acre or roughly a loss of $200/acre. While PLH damage was far greater than normal, it […]
Record acreages of emergency annual forages were seeded this summer after wheat and spring cereals were harvested. Low yields of first- and second-cut hay left many farmers with very low forage inventories. Emergency forages used included cool-season cereals (oats, barley, triticale) and cereal pea mixtures, as well as some warm-season sorghums, sorghum-sudans and millets […]
This article was originally written by Joel Bagg in 2012. It was edited August 22, 2025 by Christine O’Reilly to fix broken links to further resources. When we make corn silage and haylage, we are using our skills as microbiologists, just like winemakers, brewers and composters. As a biological system, silage making doesn’t always work […]
Forage production was extremely challenging in 2012, with low yields and tight forage inventories. Significant reductions in forage acres occurred from 2006 to 2011, of 500,000 acres of hay and 250,000 acres of pasture. Inventories of hay carried over in the spring were historically low. Export demand for quality hay to the US is very […]
A winter wheat field near Owen Sound has 4 to 5 acres of “missing plants”, cut off at the soil level. Not many insects could do that kind of damage this time of year. It sounds like a case of winter cutworm. It was to the day, 4 years ago when I wrote a CropPest […]
Leaving a minimum of 30% crop residue has been proven to minimize top soil losses from wind and water erosion. But what does 30% soil cover look like? Do certain tillage implements leave less than 30% crop residue? Crop residue in the form of corn stalks or cereal straw, or green cover (growing crops or […]
Co-Author: Albert Tenuta, OMAFRA Field Crop Pathologist The annual corn ear mould and vomitoxin survey by the OMAFRA Field Crops team indicates that the 2012 Ontario corn crop is distinctly low in ear moulds and vomitoxin. However, stakeholders are reminded that individual field conditions (environmental, hybrid, tillage, rotation, etc.) are important in ear mould and […]
