Description

Aster yellows is a phytoplasma organism. Phytoplasmas are specialized wall-less bacteria that are parasites known only to multiply in plant phloem tissue and insect vectors. There are 28 groups of phytoplasmas worldwide and seven known groups in Canada. In Canada, approximately 20 insect species can transmit aster yellows to more than 200 plant species. In Alberta, the most common insect vector is the aster leafhopper (Macrosteles quadrilineatus), also known as the six-spotted leafhopper. The leafhopper species Amplicephalus inimicus is also an important aster yellows vector in cereals.

And for the bottom line, excellent buying opportunities exist when shopping for canola co-products to increase profit margins and reduce feed costs.
