Other claims from this paper (8)
- Observation Dicofol was antifeedant against Colorado potato beetle.
- Intervention effect The 18.5% EC formulation suppressed beetle feeding at 0.05 g (AI)/Iiter.
- Intervention effect The 35% WP formulation suppressed beetle feeding at 0.2 g (AI)/liter.
- Intervention effect Technical grade dicofol suppressed beetle feeding at 0.5 g (AI)/Iiter.
- Observation Field EC dicofol showed a rate response in 1983.
- Intervention effect The EC formulation was more residually effective than WP in 1984.
- Intervention effect Two timed EC applications kept 1984 defoliation below 20%.
- Observation Weekly WP applications were required for similar defoliation protection.
