Keep Records on Pests

They’re back! Insect pests, plant diseases, weeds, birds, biting flies — the works. And tracking them year to year is critical. How better to know your options are, this year and in years to come?

So pick up a pencil, smart phone or tablet and write them down on a field-to-field or livestock basis. Write your observations over the course of this summer — each while it’s fresh in your mind. Did potato leafhopper infestations go over threshold in alfalfa? Were corn diseases a problem? Which diseases and what hybrid were infected? Did you have corn rootworm injury? Did you lose wheat to snow mold? Were there new weeds or weed escapes you didn’t expect this year? Got more house flies on your cattle than past years? And bear in mind: cereal leaf beetle is increasing from year to year on wheat. Have you seen it yet?

These records help you better select which management practices to use now and in the future. For example, if you were hit with potato leafhoppers this season and you want to rotate your alfalfa, one management option is to use potato leafhopper-resistant alfalfa. Another example: choose wheat varieties resistant to certain diseases — based on field observations you wrote down last fall.

Likewise, if you have weed escapes you might reconsider your weed control products or even use methods like cultivation Or lots of house flies on your cattle and you sprayed could mean the flies became resistant to the insecticide.

WRITE IT DOWN! Keep records of pests you observe — and their threshold numbers. Because if you wait too long, you might forget what happened.
