Summary Of Leafhopper Activity To Date

 

Almost all first brood nymphs of Virginia creeper leafhopper (VCLH) and Western grape leafhopper (WGLH) have emerged and many of these nymphs are now late instars that are close to molting into adults (i.e. second brood). As these nymphs complete their development, we expect to see increased densities of VCLH and WGLH adults in the coming weeks. These second brood adults will lay eggs higher up in the vine canopy.

 

This week we are providing a summary of adult, egg and nymph densities of VCLH (Fig. 1) and WGLH (Fig. 2) at each of the monitoring sites.

 

Releases of Anagrus daanei (the parasitoid that attacks VCLH) will resume at the end of this week.

 

 

 

 

 

Video: Independent Seed, National Impact | On The Brink: Episode 9

A survey of 200 independent seed businesses reveals what Canada's seed sector actually contributes — and what it stands to lose.

On the Brink, Justin Funk, a third-generation agri-marketer, shares the findings of a national survey conducted in early 2026. The numbers reframe the conversation: independent seed companies in Canada represent upwards of $1.7 billion in dedicated seed infrastructure, approximately 3,000 full-time equivalent jobs in rural communities, and an estimated $20 million in annual community contributions. And roughly 90% of Canada's cereals, pulses, and other small pollinated crops flow through them.

The survey also asked how dependent these businesses are on public plant breeding to survive. The answer was unambiguous. For policymakers evaluating the future of publicly funded breeding programs, Funk argues the economic case for this sector and the case for public plant breeding are the same argument.

On the Brink is a cross-country video series exploring the future of plant breeding in Canada. Each episode features voices from across the industry in an open, ongoing conversation about innovation and long-term investment in Canadian agriculture.
