Why Test Seeds?
Seed-transmitted pathogens can introduce new diseases into a field and can perpetuate existing infestations. This results in yield reduction and poor quality seed. Testing helps to identify healthy seed lot for planting thus mitigating against pathogen-induced losses. In addition, importing countries (Asia, Europe, South America, etc.) have varying acceptable thresholds for seedborne pathogens. Many require exporting countries to test their seed lots to certify that they do not exceed the thresholds or the pathogen is not present. In order for the importing country to receive a shipment, it may require a ‘phytosanitary certificate.’ (Click on USDA-APHIS for more information.)
