Other claims from this paper (19)
- Method / resource Potato and cabbage-leaf bait counts did not correspond to wireworm numbers in soil.
- Observation There was no conclusive evidence for different fumigant action across wireworm size groups.
- Observation Mean starting wireworm density was 65 per square yard in the first experiment.
- Observation Mean starting wireworm density was 335 per square yard in the second experiment.
- Observation Mean starting wireworm density was 277 per square yard in the third experiment.
- Mechanism Uneven wireworm distribution caused high sampling errors, accounting for most experimental error.
- Association Soil pH was unrelated to wireworm density.
- Observation Untreated control populations changed by −23% in the first experiment.
- Observation Untreated control populations changed by +1% in the second experiment.
- Observation Untreated control populations changed by −9% in the third experiment.
- Intervention effect Fumigant K reduced wireworm populations by 69%.
- Intervention effect Fumigant S reduced wireworm populations by 62%.
- Intervention effect K and S adversely affected sugar-beet.
- Intervention effect K and S had a residual effect reducing wireworm counts the next year.
- Intervention effect K and S increased the following year barley plant stand.
- Intervention effect K and S did not significantly increase final barley yield.
- Intervention effect Chlorpicrin reduced wireworm populations by 46% in one trial.
- Intervention effect Chlorpicrin reduced wireworm populations by 33% in another trial.
- Intervention effect Chlorpicrin caused no harmful effect on sugar-beet or barley.
