What is Cultural Pest Control?
“Cultural control” is a way of suppressing pests with the way you manage your production.
It’s about Interrupting an Insect’s Life Cycle
In a traditional agriculture system, common cultural controls would be tillage, strategic planting dates, or crop rotation- all practices that in some way interrupt an insect pest’s life cycle. A few of the old cultural controls can be rolled over to greenhouse production, of course, but a different setting requires that greenhouse producers rethink the way that they approach cultural controls.
Bright Agrotech has found several cultural control methods that fit our greenhouses and aquaponics setup.
Here are six cultural pest control methods to help you:
1) Keep your greenhouse clean to thwart pests
Another sanitation technique that is frequently employed by greenhouses is the steaming of soil, crates, and pots before use. Steaming kills off many harmful bacteria and insect pests.
2) Controlling pests with plant-to-plant interactions (inter-cropping)
When diversity goes up, several things happen. The first thing is that the pest no longer has a huge amount of its favorite food (or habitat) all in one place. Instead the “food plant” grows in patches. Some pests can’t travel very far and never make it out of their patch. This keeps the pest population from booming. Instead one large, widespread pest population, you have a few smaller – and less destructive/hopefully more manageable – populations.
3) Exclusion as a cultural pest deterrent
4) Excluding with crop spacing
5) Excluding with trap crops
6) Excluding with proper nutrient levels
The primary nutrient you’ll want to be really careful about is nitrates, which impact the development and production rates of insects. (Especially aphids, which go bonkers if there is an abundance of nitrates.) Since nitrogen enters your system in the form of the protein from fish feed, your main tool for controlling nitrogen levels will be controlling your fish feed.
