IV. Integrated Control1. Adjust cultivation management: Reasonably fertilize and water, enhancing the aphid resistance of begonias. Avoid excessive application of nitrogen fertilizer to prevent the massive reproduction of aphids.2. Crop rotation: Regularly change the planting location to avoid continuous cropping and reduce the accumulation of aphids in the soil.3. Plant aphid-resistant varieties: Choose begonia varieties with strong aphid resistance to reduce the occurrence of aphids from the source.
In summary, to completely eliminate aphids on begonias, it is necessary to use a combination of control methods.
