PGRs
Hybrid barley is drilled at a low seed rate to achieve the full yield and grain quality potential. From GS30 onwards growth is rapid so the following PGR programmes are recommended:
• GS30-31: Moddus 0.1-0.2 lt/ha + chlormequat 1.2-1.5 lt/ha
• GS37-39: ethephon + mepiquat 0.5-1.0 lt/ha
In very fertile situations consider splitting the first dose of growth regulators:
• GS29: Moddus 0.1lt/ha + chlormequat 1.2 lt/ha
• GS31: Moddus 0.1lt/ha + chlormequat 1.2 lt/ha
• GS37-39: ethephon + mepiquat 1.0 lt/ha
