Critical weed-free period

Weed-free period in corn In corn this period occurs from V1 to V6 (1 to 6 leaf collars). Some sources will mention that it even begins at the VE stage (emergence). During this time the corn crop needs to stay clean. Weeds will affect yield

Early season pests

With the cold winter that we have had, a slow start of insect development may occur. Many of the acres planted in Ontario have been planted with neonicotinoid insecticides. With the current debates over neonicotinoid insecticides, the best strategies to control pests is to start with a good knowledge of crop pests. By understanding early […]

Wheat leaf diseases

How do I know when to apply a fungicide? The higher the price of wheat, the more economical treatment is. In general, if trace amounts of rust, powdery mildew, or leaf spot are

Micronutrients — more important than you think

Micronutrients are essential to plant growth and aid in achieving yields that growers need. Unlike a macronutrient such as nitrogen, phosphorus and potassium, micronutrients are required by the plant in small amounts, but are equally as important for proper crop growth and yield. The micronutrients that are key to growth include Boron, Copper, Iron, Manganese, […]

Snow mould in winter cereals

Holly Loucas, Agronomist, DOW Agroscience What is snow mould? Snow moulds are cold-loving fungi that can attack many economic plants under a cover of snow. Pathogen biology The important species of snow moulds that infect winter wheat are Microdochium nivale and Typhla spp. Gray snow mould (Typhula spp) is the less damaging form of snow […]

Frost seeding clover

With the snow beginning to melt and spring just around the corner, it’s time to begin thinking about seeding your clover cover crops on the frost for your winter grains. Clover is still one of the most beneficial cover crops to use when you have a winter grain crop. Thompsons Agronomy has put together some […]

Reduce production costs without sacrificing yield

Falling commodity prices mean growers are concerned with their profit per acre. Input costs have remained high and have not adjusted to where farmers believe they should be. Until prices change, strategic adjustments will have to be made to stay profitable during lower commodity pricing years. Thompsons has identified 5 ways to help you reduce production costs without sacrificing yield.

2014 Grain Corn Ear Mould and Vomitoxin Survey

Greg Stewart, OMAFRA Corn Specialist; Albert Tenuta, OMAFRA Field Crop Pathologist The OMAFRA Field Crops team has completed the survey of the 2014 Ontario corn crop to determine ear mould incidence and the occurrence of mycotoxins in the grain. These mycotoxins, particularly vomitoxin (DON) produced primarily by Gibberella/Fusarium ear moulds, are grading factors and can […]
