The area ofpulses grown in the UK has increased 24% to 171,000 ha compared with 2014 due,in large part, to the introduction of the three-crop rule. Such a large croparea suggests the both peas and beans are making a re-appearance on farms wherethey havent been grown for many years. This has raised fears that lossescaused by pod-shatter may be unnecessarily high if growers dont take action byapplying a suitable pod sealant, such as Pod-Stik.
According to trials performed by theProcessors & Growers Research Organisation (PGRO) applying the pod sealantPod-Stik delivered a consistent increase in yields compared with untreatedcrops.
Kim Christo of Pod-Stik manufacturer DeSangosse says trials have shown that it is best applied at Growth Stage 80 whenpods become black.
We know from work over successive yearsthat Pod-Stik delivers an average yield saving of almost 600 kg/ha when appliedto beans and 400kg/ha in peas depending on crop condition and efficiency ofapplication, but timing is highly important if the lower pods are to becovered, he says.
Separate trials have also highlighted theimpact of nozzle choice when applying a pod sealant.
The thicker the crop the more difficultit is to penetrate the canopy and ensure all pods are suitably covered. This ismore so with peas than beans because of the greater quantity of biomass.Consequently, trials have identified that losses can be dramatically reducedwhen switching to flat fan, rather than angled nozzles before applying Pod Stikto peas, says Kim Christo.
Pod-Stik can be applied alone or with adesiccant such as glyphosate or diquat, but in all cases it is important thatsprayer lines and nozzles are flushed with clean water to avoid any blockagesafter use.
