Abstract

PRE herbicides are less effective in the zero-tillage system because of increased residual crop stubble and reduced soil incorporation. However, since weeds are not physically controlled in the zero-tillage system, reliance on efficacy of PRE herbicides is increased. This research investigated the impact of carrier volume and droplet size on the performance of PRE herbicides (in wheat crops at four sites in 2010) to improve herbicide efficacy in conditions of high stubble biomass in zero-tillage systems. Increasing carrier volume from 30 to 150 L ha−1 increased spray coverage on water-sensitive paper from an average of 5 to 32%. Average control of rigid ryegrass by trifluralin (at Cunderdin and Merredin sites) and trifluralin or pyroxasulfone (at Wickepin and Esperance sites) improved from 53 to 78% with increasing carrier volume. Use of ASABE Medium droplet size improved spray coverage compared with ASABE Extremely Coarse droplet size, but did not affect herbicide performance. It is clear that increased carrier volume improves rigid ryegrass weed control for nonwater-soluble (trifluralin) and water-soluble (pyroxasulfone) PRE herbicides. Western Australian growers often use low carrier volumes to reduce time of spray application or because sufficient high-quality water is not available, but the advantages of improved weed control justifies the use of a high carrier volume in areas of high weed density.

Los herbicidas PRE son menos efectivos en sistemas de labranza cero debido a su menor incorporación en el suelo y la mayor cantidad de residuos de cultivo. Sin embargo, como las malezas no son controladas físicamente en los sistemas de labranza cero, la dependencia en la eficacia de herbicidas PRE es mayor. Se investigó el impacto del volumen de aplicación y el tamaño de gota en el desempeño de los herbicidas PRE (en cultivos de trigo en cuatro localidades en 2010) para mejorar la eficacia de herbicidas en condiciones de alta biomasa de residuos de cultivo en sistemas de labranza cero. El incrementar el volumen de aplicación de 30 a 150 L ha−1 aumentó la cobertura de la aplicación, medida con papel sensible al agua, de 5 a 32%. El control promedio de Lolium rigidum con trifluralin (en las localidades Cunderdin y Merredin) y trifluralin o pyroxasulfone (en Wickepin y Esperance) mejoró de 53 a 78% al incrementar el volumen de aplicación. El uso de gotas ASABE de tamaño mediano mejoró la cobertura de la aspersión al compararse con gotas ASABE extremadamente grandes, pero no afectó el desempeño del herbicida. Está claro que el incrementar el volumen de aplicación mejoró el control de L. rigidum con herbicidas PRE insolubles en agua (trifluralin) y solubles en agua (pyroxasulfone). Los productores del Oeste de Australia usan frecuentemente volúmenes bajos de aplicación para reducir el tiempo de aplicación o porque no hay suficiente agua de alta calidad disponible, pero las ventajas del mayor control de malezas justifica el uso de altos volúmenes de aplicación en áreas con alta densidad de malezas.
