Keep eye out for lodging warns BASF
Keep eye out for lodging warns BASF
RECORD rainfall could trigger widespread lodging in autumn-sown cereals, warns BASF.
Many main crown roots which hold plants upright have grown poorly in waterlogged soils, says the firms Lance Middleton.
"The anchorage system of the plants is likely to be too weak to resist the leverage of the stems and leaves above ground," he explains.
Waterlogged winter wheat and barley should benefit from growth regulator from early to mid-tillering. Applied at the earliest recommended stage, New 5C Cycocel (chlormequat) promotes root development as well as shortening stems, says Mr Middleton.
"Contrary to popular opinion, stem or straw strength is not the only factor causing lodging. HGCA-funded research found poor root anchorage is equally important." *
