The Canola Export Ready program is an information program communicating information to producers and industry on the various issues that can affect canola markets. Growing unregistered varieties, Lindane usage, exceeding maximum residue limits, and using Malathion to treat bins that will be used to store canola are all issues that can restrict market access. Producers are urged to visit our website www.canola-council.org and click on the link Canola Export Ready. 

During this past growing season producers encountered some challenges, one of which was the heat experienced in July and August. One of the problems associated with this heat was missing pods. In most cases missing pods that were noticed could be blamed on the heat, but also there were other causes. Producers are urged to visit the website and download the Canol@fact sheet called “Missing Pods”. 

Another problem that was seen in some areas was bertha armyworms. This problem has the potential to increase in intensity next year, but parasitism has been noticed in some areas. The threshold levels recommended is based upon the fact late instar larvae eat approximately 0.058 bu under cool moist growing conditions. However some research is showing that in dryer hot conditions where the plants are senescing quickly the amount of canola eaten (damage) can increase by 50% thus lowering the threshold levels.
