Other claims from this paper (14)
- Intervention effect Very-low-volume CDA with Agral was less effective against Avena fatua than conventional spraying.
- Observation Without difenzoquat, the additives were inactive against A. fatua.
- Observation Additives had little direct effect on wheat and barley and did not substantially increase difenzoquat phytotoxicity.
- Intervention effect Smaller difenzoquat drops were more active against wild oat than larger drops.
- Intervention effect Reducing spray volume from 40 to 5 litres per hectare reduced phytotoxicity.
- Intervention effect Oil and surfactant additive improved all difenzoquat CDA treatments.
- Observation The additive interaction with application treatments was not statistically significant.
- Intervention effect After rain at 2 or 5 hours, CDA was less phytotoxic than conventional application.
- Intervention effect Oil and surfactant improved CDA performance after simulated rain.
- Observation With rain withheld for 24 hours, the additive had less effect.
- Intervention effect In the field, oil and surfactant improved wild oat control with both spray methods.
- Intervention effect The additive did not increase wheat injury.
- Observation Oil and surfactant mixtures improved spray spreading and wetting.
- Mechanism Improved spray spreading reduced local contact injury and was suggested to improve uptake and translocation.
