“COMMUNITY” PEST ALERT: Spotted Lanternfly

They may be pretty, but they aren’t our friends. Spotted lanternfly (SLF) is an invasive sap-feeding planthopper with potential to harm agriculture and forestry in Ontario.

But I only grow greenhouse fruits and vegetables, so why does it matter to me, you ask? Read on to learn more about why this pest matters to everyone.

SLF: The Issue

Although not considered a huge threat to our greenhouse crops, we can still do our part in our communities. If you enjoy the benefits of orchards, vineyards, agroforestry or nurseries or you have neighbours, friends or family that produce these commodities, then you are part of this community.

There are currently NO ESTABLISHED POPULATIONS of SLF in Canada, but interceptions have occurred at several border crossings, so this is an imminent threat.

Spotted lanternfly is a quarantinable pest in Canada. It is important to report any sightings immediately to the Canadian Food Inspection Agency.

Steps to take if you suspect SLF:

  1. Take a photo or video
  2. Collect specimens including adults, nymphs or egg masses
  3. Report

Tip: To assist with early detections, pay close attention to any tree-of-heaven‘s that you have on or near your properties since these are preferred hosts for SLF.

Below are some resources that can be used to spread awareness including:

Deficiencies Got You Down?

Image
This post was contributed to by Abigail Wiesner and Chevonne Dayboll. As we move through production for fall and winter crops a refresher for nutrient deficiencies feels appropriate. No matter where you are in a cropping cycle, nutrition problems can be tricky to figure out. The good thing is they can be differentiated from disease or pest issues based on a few key observations: If the damage is uniform and crop wide , it’s most likely a nutritional issue If the damage is localized or more random , it’s most likely a disease or pest issue How to Spot a Nutrient Deficiency Early detections of any problem can be caught with regular monitoring . Detection is STEP ONE : Figure 1. Common nutrient deficiency indicators for floriculture crops. Nutrient Mobility : When deficient, mobile nutrients will move to the new growth, but immobile nutrients will be trapped in the old growth. A quick scan of where the damage is occurring can help to narrow the potential culprits. Stunted...
