What makes verticillium even trickier
is that pathogen load doesn't seem to
impact disease severity. It's possible to
have a lot of verticillium in a field, but
very few issues. Conversely, very little
verticillium can become a severe issue.
" It's a very complicated knot to untie, "
said Wheeler.
Pathogen load isn't the only wild card
when it comes to disease outbreak.
In some cases, microbes present in
the soil suppress the verticillium. In
others, both fertility and weather can
play a role. When soil moisture is high,
the pathogen grows and spreads quite
quickly, but when soil moisture levels
are low, wilt can be more severe. Where
soil fertility is low, wilt may be even
more severe. High nitrogen rates tend
to delay the onset of symptoms.
Interestingly, Wheeler said farmers
Verticillium leads to visible wilt on the above-ground leaves of the potato plant. Its effect on
tubers can be dark streaks or rings internally.
growing potatoes in soils that have
never been exposed to potatoes before
report a 14-20% yield boost in some
cases. Researchers working to better
understand the impact of " virgin soils " on
potato health. Their first aim is to verify
the claims. To do so, they are conducting a
