Oilseed rape volunteers. At the outset they seem small and innoccous, hardly something that would threaten maize then? OSR has large leaves, deep roots and is a fierce competitor for nutrients, light and moisture and has a very severe effect of maize plants ability to grow. It is well known that maize doesn't like competition, it doesn't like scavenging for nutrients either!
Volunteer oats that had not been controlled in the first premergent spray coming through in this field of Lorado grain maize. Similar issues with a few growers this season, the dry period at drilling in late April meant that not all herbicides were as effective as they should have been. The resultant checking and uneveness in the picture below this shows control achieved, but at the resultant cost to plant growth, along with striping due to uneven fertiliser uptake, as shown in previous post.
