Also noticed on all varieties was some flea beetle damage. The tender cotyledons are like candy to those pesky little black insects. Flea beetle damage looks like little chew marks on the leaves; they will start to feed on the cotyledons first. Threshold levels are where there is 25% damage to the cotyledons.
Throughout the field there is light to moderate weed pressure. Once the ground dries up, we will be spraying the plot. The InVigor varieties will be getting 1.35 L/ac of Liberty and Centurion. As for the Roundup Ready varieties, we will be going in with 0.5 L/ac of glyphosate.
There is no lack of water in this year’s canola plot, as the moisture levels are excessive. All that the plot needs now is a little bit of sunshine to heat things up and get things growing!
