In this edition of the Guelph Service Bulletin, we will discuss a new test option for our forage customers, greenhouse testing and a reminder on restocking your sample supplies.

NEW TEST! AFLATOXIN B1

SGS Guelph is now offering Aflatoxin B1 testing by Elisa method.  This test has been increasingly requested, especially on alfalfa hay samples, as it is a potent mycotoxin produced by Aspergillus mold.

GREENHOUSE TESTING

Greenhouse operations are heading into another growing season, which is a good time to consider a strategy to monitor plant health with the DNA multiscan analysis. Early detection of pathogenic species and subspecies can be a valuable tool in plant maintenance. The DNA multiscan has a ‘Short’ package that is used for monitoring, and detects the most common fungal pathogens, and a ‘Long’ package which is used for diagnosis, as it contains many more subspecies.

We also offer viral and bacterial testing, such as pepino mosaic virus and bacterial tomato canker. When submitting samples, please provide symptomatic tissue (not dead), and a brief summary of the symptoms and their progression.

RE-STOCKING SAMPLE SUPPLIES

The winter months are a good time to check sample supply inventory. Contact the laboratory if restocking is required, and we will gladly ship a three month supply.
