Unstable weather in Manitoba springs often yields severe storms producing hail. There is a major benefit of spring hail over summer/fall hail events, which is the ability of a crop to recover and have very little yield impact. There is… Read More

Bt corn varieties resistant to European corn borer will contain one or more Bt proteins, each of which are toxic to European corn borer in their unique ways. In Bt corn, these proteins go by names such as Cry1F, Cry1Ab,… Read More

The 2022 growing season had varied precipitation accumulation across the province, not only due to heavy spring flooding but throughout the season. In late October, the Available Water Holding Capacity was measured from 0 – 120 cm depth in over… Read More

This study looks at the ability to increase or decrease planting populations from what the farmer normally does, in order to improve yields. Management practices can be changed with improved hybrid availability, including changing planting populations in grain corn. 22… Read More

The most common reason for uneven corn emergence is soil moisture. Soil moisture in the seed zone can differ because of variations in soil type and topography, as well as uneven distribution of moist and dry soils due to secondary… Read More

Corn development is categorized into vegetative and reproductive stages. Reproductive growth refers to all development that determines kernel number and size. The reproductive stage is broken down into subdivisions, identified numerically. Read More

Early season insect pests can begin feeding on seed corn even prior to germination, while some feed beyond V6 (6 leaf collars), depending on the insect’s life cycle and time of year. Read More

Corn development is categorized into vegetative and reproductive stages. Vegetative growth refers to leaf and stalk development and elongation. The vegetative stage is broken down into subdivisions, mainly identified numerically. Read More

This factsheet represents herbicides registered on field corn and available as of April 2021. This list can change quickly, and it is recommended to always refer to the Guide to Field Crop Protection and herbicide labels before in-field applications. Read More
