| 🇬🇧 | 🇬🇧 |
| Name 2 brewing SB varieties | Propino, planet |
| Name a hybrid barley variety | Kingsbarn |
| What grain N should be targeted for malting? When should N be applied to prevent grain N excess? | 1.8, mid March |
| What additional authorisation body must approve malting barley PPPs (fungicides) as they affect yeast? | BBPA and BRI |
| What are advantages of a 6 row variety? | Higher yield potential, more vigorous |
| What are disadvantages of 6 row variety? | Smaller grains so higher volunteer issue, taller straw, expensive seed |
| When should WB be sown? | Mid September - mid October |
| What are the dangers of drilling too early? | Early vernalisation and ear damage |
| What are the dangers of drilling to late? | Loss of tillering |
| What is the optimum plant population in spring? | 300 plants/m2 |
| What is barley more sensitive to compared to wheat? | Waterlogging and hard winters |
| When is the optimum N application timing in WB? | Half at late tillering (February) and half at GS30-31 |
| Why specifically is barley more competitive against BG than wheat? | Root mass outcompetes BG |
| What are Pre-em options for Barley? | Pendimethalin, Flufenacet, Diflufenican, Prosulfocarb, triallate |
| How can you justify BG control with Axial Pro? | If it is used as part of an integrated control strategy |
| What pre-em herbicides are good for control of brome in barley? | Triallate, flufenacet and dff |
| What are the main diseases of barley in the UK? | Rynchosporium, ramularia, net blotch, powdery mildew, brown rust, leaf stripe |
| How is rynchosporium spread? What are high risk conditions? | Rain splash, wet warm climates |
| What are high risk conditions for net blotch? | Inoculum builds up overwinter and flares during warm humid spring |
| When is T0 for Barley? What might you apply and to control what? | GS25-29, tebuconazole, azoxystrobin, cyflufenamid, powdery mildew, brown rust and overwintering net blotch inoculum |
| When is T1 for Barley, what might you apply and to control what? | GS30-32, prothioconazole and bixafen, net blotch, rynchosporium, brown rust |
| When is T2 for Barley, what might you apply and to control what? | GS39-49, prothioconazole and bixafen or revystar, ramularia, rynchosporium, net blotch, loose smut, fusarium |
| When should the first PGR be applied, why and what products? | GS30-32, encourage tillering and reduce lodging risk, chlormequat and trinexapac-methyl |
| What is the risk to the early PGR applications? | Sudden cold weather, can scorch the crop |
| What is another early PGR that can be applied, why and what products? | GS30-39, stem thickening, reduce lodging, chlormequat and mepiquat, more effective at lower temperatures and kinder on crop |
| What is the cut off for PGR use? | When boot has split and ears are visible or temperature is >21 degrees |
| When is the late (second) PGR to be applied to barley, why and what product might be used? | GS32-49, stem thickening, reduce lodging and brackling of ears, Terpal |
| What BLW post-em herbicides are available in barley to be applied in the spring? | Amidosulphuron, thifensulfuron, metsulphuron, Fluroxypyr, florasulam, mecoprop |
| What is the SB sowing timing? | Late December - mid May |
| Why is it beneficial to sow SB early? | Maximise yield and dilute N to achieve lower grain N |
| What is the target plant population for SB? | 30 plants/m2 |
| What is the bet seed treatment for SB, what are the actives and what does it protect against? | Redigo pro, prothioconazole and tebuconazole, seed bourne diseases |
| What is the general rule for N in SB? | Later the crop is sown, earlier the N is applied |
| What must manganese not be tank mixed with? | Hormone herbicides |
| What can be done to the same fungicides in SB as used in WB and why? | Reduced rates as less persistence is required |
| What Pre-em herbicides can be used in SB? | Pendimethalin, Prossulfocarb (EAMU), Liberator (EAMU) |
| What SB herbicides groups are available to control BLW? | SU's, hormones, Fluroxypyr, flurasulam |
