Lodging is a major crop production issue, especially in high yielding environments. Yield losses can range from 5 to 40%, with the greatest losses occurring when lodging occurs ten days to two weeks following head emergence. When the crop lodges early in the season, before full stem elongation, plants may recover by “elbowing” to an upright position. Once the crop has flowered, heads will not regain an upright position. Lodging can be managed through variety selection and agronomics. Crop varieties vary in their resistance to lodging, with stem length, thickness of stem internodes, root structure, and head density and shape affecting resistance to lodging. Producers are encouraged to review lodging ratings in Seed Manitoba when selecting varieties. Seeding and nitrogen rates also play a role in lodging. Internode shading increases with increasing plant populations, which can increase internode elongation and create taller, weaker stems. High nitrogen rates can have a similar effect with excessive tillering leading to increased internode shading and elongation. Plant growth regulators (PGRs) are another management tool used to reduce lodging. PGRs are synthetic compounds that alter hormonal activity to modify plant growth and development. PGRs are used to improve crop standability, as they are intended to produce shorter, thicker, and stronger stems. There are two main groups of PGRs, ethylene releasing compounds and gibberellin inhibitors. Gibberellin inhibitors such as Manipulator (active ingredient chlormequat chloride) are the more common type of PGR in Western Canada. The effects of PGRs are not well known. There are reports of PGRs increasing yield, as well as reports of PGRs causing stem elongation and reducing yield. The objective of this project is to demonstrate the effects of PGR application on spring wheat height and yield.

The project objectives were to evaluate the effectiveness of pre-harvest herbicide/desiccant applications for assisting plant and seed dry-down for the two dominant herbicide systems (Liberty Link® and Roundup®). The options and relative performance for Clearfield® canola would presumably be similar to Liberty Link® canola.
