Thosewith crops of field beans are being advised to consider applying a pod sealantto protect against losses during combining.
Accordingto trials performed by the Processors & Growers Research Organisation(PGRO) applying the pod sealant Pod-Stik delivered a consistent increase inyields compared with untreated crops.
Withex-farm prices for November currently trading at 180-185/tonne before premiumsthe margin over feed wheat of 70-73/tonne is at an historical high so anyintervention that reduces losses should not be overlooked, says the PGROstrials officer Jim Scrimshaw.
Forsome growers beans are likely to be one of the more profitable crops thisharvest so it makes good sense to protect yields through an application ofPod-Stik, he says.
Althoughbean crops will be nearing harvest Mr Scrimshaw says it is still worthwhileapplying a pod sealant to reduce header losses.
Unlikeoilseed rape where it is more important to seal the pods in the upper raceme ofthe plant it is the lower pods of the bean plant that tend to become brittleand at-risk of splitting. It makes sense to wait until crops are sufficientlysenesced to allow good penetration, he adds.
KimChristo of Pod-Stik manufacturer De Sangosse says trials have shown that it isbest applied at Growth Stage 80 when pods become black.
Weknow from work over successive years that Pod-Stik delivers an average yieldsaving of almost 600 kg/ha depending on crop condition and efficiency ofapplication, but timing is highly important if the lower pods are to becovered, he says.
Pod-Stikcan be applied alone or with a desiccant such as glyphosate or diquat, but inall cases it is important that sprayer lines and nozzles are flushed with cleanwater to avoid any blockages after use.
