Best use of slug pellets in Oilseed rape
The Problem
• Many OSR crops receive more than one application to establish and maintain an even plant stand but trials have shown this is not always necessary
• OSR is most vulnerable to slug damage between germination and the 2 leaf stage when stems can be bitten through causing plant loss
• When planning control programmes make sure you use the most effective slug pellet available at this critical timing
What to do;
• Identify fields and field areas at highest risk (monitor stubbles for slug activity using traps baited with layers mash prior to drilling)
• Treat vulnerable crops immediately if conditions favour slug activity (trapping is not always a reliable guide to slug damage risk in OSR)
• Apply Draza® forte at full rate (3.75kg/ha) just prior to emergence
• Continue to monitor crops and apply a second application only if necessary according to risk and field conditions
Oilseed rape - New best advice
|
Draza forte • High quality Wetex pellets work harder and last longer • Remain effective even in cold and wet conditions • Give consistent, reliable slug control every season • Won’t let you down when you need them most |

• To grow high yield potential OSR crops, aim to establish fewer plants/m2 in order to produce a more open canopy • Thinner crops often yield better, but need the best available slug protection to avoid patchiness or crop failure |

• Draza forte is a wet extruded durum wheat pellet and includes a high quality binder making it more resistant to degradation and mould growth • Uniform pellet shape, size and weight promotes even spreading plus they resist damage from spinning disc spreaders |
