What is a pest?
Please note the correct use of the word “pest” in agriculture includes insects, animals, viruses,
bacterium, and fungi (and a other things, but you get the idea). There are major garlic pests that MAY
be spread by the “seed” garlic heads that you buy for your garden or farm. Chief and most serious
among these are White Rot and Bloat Nematode. One of these more serious pests introduced to your
soil (and then into any current garlic you have) can eliminate your ability to ever grow garlic and
onions again. Botrytis, Fusarium, and Penicillium mold are also problems. Leek Moth and a few other
insects are up and coming. Each year I find that many potential customers have never heard of these
concerns. Keep in mind that your own current or past plantings of bulbs, onion sets, and other plant
material might have already introduced these pests into your garden or farm. Clean and healthy
purchased “seed” garlic can be infected by pests already present in your home plot.
