Noted in Canada Weed Control guide that for Roundup Ready canola they recommend that up to 6 leaf stage and then stop. Indicated that plant yellowing occurs when applied on the late side. Reports of sulfur problems showing up in canola. We can foliar apply when canola is in the 5-6 leaf stage and during early bolting as a rescue treatment. I applying earlier then too much leaf burn can occur and if late in flowering stage both damage to flowers and new pods may not set seed.
Some corn stand and rooting problems because of shallow planting into wet soils.
They dried out rapidly and poor stands resulted. Recent cool nights experienced in the Valley, have revealed some herbicide selectivity among corn and soybean varieties to post applications of herbicides. Situations can occur in which a crop may be injured by a herbicide to which the crop is normally tolerant. This occurs when environmental stresses such as hot or cold temperatures, relatively high humidity or hail decrease a plant's natural ability to reduce herbicide uptake or deactivate a herbicide. Any stress on a plant takes energy in order for the plant to compensate, energy that normally would be used for other growth and production processes or general defenses.
