With the holiday season almost upon us, it’s time to turn our attention to Spring bedding crops. Although here for a brief window, the diversity of these crops means you’re bound to encounter some sort of disease and insect problems.
One way you can head off issues is to plan and prepare now. This post from January 2020 has important tips on sanitation for common spring crop diseases, dips and early sprays to prevent key pests, as well as tips on where to spend your biocontrol dollars.

Hosing down saves Headaches:
Several key spring crops, like Calibrachoa, Pansy and Petunia are highly susceptible to black root rot (Thelaiviopsis), and I’m seeing more Fusarium pop up in random crops the last few years (e.g. salvia, gerbera, echinacea, lavendar). These pathogens are everywhere in the environment, and can easily be brought in by insects (fungus gnats and shoreflies), on worker’s boots or via equipment. Further, their spores can hide in nooks and crannies of benches while less-susceptible crops are growing, then pounce when conditions are right.
