Cucumber Mosaic Virus – sowing healthy seed is critical

Aphid-borne virus epidemics are favoured when a significant source of virus infection is present, and climatic conditions (warm weather, rainfall sufficient for green bridge development) favour aphid buildup. Best management for seed-borne pulse viruses, such as Cucumber Mosaic Virus (CMV) starts with maintaining a healthy seed source. Sowing healthy seed […]

Diagnosing plant diseases: What do we ask and why do we ask for it?

Diagnosing a plant disease or other injury is like going to a medical doctor who must ask several questions before making an accurate diagnosis and recommending a treatment. If you withhold information, it can lead to a misdiagnosis. The same goes for crop diseases. Plant pathologists, specifically diagnosticians, are often […]
