A common misconception is that organic farming means accepting losses from pests. In fact, the organic system is based on a multi-layered prevention strategy, in which spraying any preparation is only a last resort when previous layers are insufficient.
First layer: prevention by system design
Choose varieties that are suitable for local conditions and are resistant to diseases, arrange cropping seasons to avoid the peak of major pests, rotate crops to cut the life cycle of pests in the soil, and keep reasonable planting distances to keep the canopy clear. Most serious pest problems can be mitigated through crop planning.
Second layer: encourage natural enemies
Ladybugs, parasitic wasps, spiders, birds and many other species provide natural pest control if their habitat is maintained. Planting flower strips along the edges of fields, maintaining shrub hedges, limiting soil disturbance and avoiding broad-spectrum products that kill natural enemies are ways to nurture this biological control force.
Third layer: monitoring and action thresholds
Organic farmers often visit fields regularly, set traps to monitor and record pest densities. Only when density exceeds a threshold that can cause economic damage should intervention be made. Spraying rooms on a fixed schedule, not based on observation, is not consistent with organic principles.
Fourth layer: direct measures are allowed
- Catch by hand, sticky trap, pheromone trap, insect net.
- Natural enemies are raised and released to supplement.
- Biological products and some active ingredients of natural origin are on the list of permitted standards.
All materials used for pest treatment must be tested for validity against certification standards before use, and must be recorded in the field diary.
Accept a level of damage
Organic systems do not aim to eradicate pests but to keep them below the harmful threshold. A small pest population is also needed to maintain a food source for natural enemies. Changing the mindset from "destroy" to "balance" is the most important step when getting acquainted with organic farming.
