Active Prime, Active Build and Active Grain fill crop response in wheat

By Dumbleyung 2020, Dumbleyung Nutrition 2020

Objective

To evaluate the efficacy of Active PRIME, Active BUILD and Active Grain FILL on seed germination, vigour, disease rating, grain yield and grain protein content in wheat.

Background

ROI  = (t/ha*grain price)-$/ha of product. Product prices excluding cost of clearing and handling, margins of distribution and retail level.

CBH receival standards

Key Findings

  • No significant yield difference between treatments.
  • Higher emergence numbers in plots treated with active prime seed treatment.
  • Active prime 4ml/kg achieved 15% & 18% increase in crop emergence numbers for both treatments respectively.
  • Treatment differences were not visible past tillering.
  • No significant difference between Active Prime 4ml/kg seed treatments stand alone and Active Prime 4ml/kg followed by Active build 2.5L/ha and Active Grainfill 2.5L/ha.
  • Higher plant density at emergence in Active Prime treated plots, translated into vigour observations later in the season. Wheat yields were lower than expected, around 2.5 t/ha, as a result of low growing season rainfall.
  • Soil pH 5-5.5 should have healthy soil microbial activity and nutrient availability. In this season responses were not significant.

Barley Fungal Systems

By Fungicides 2020, South Stirlings

Objectives

  1. Highlight the “do’s and don’ts” of fungicide use in barley.
  2. Demonstrate effective MOA rotations and mixes.
  3. Demonstrate effective seed treatments, Z32 foliar applications and Flag leaf applications.

Background

The trial was sown on the 25th of May in the South Stirlings region on a paddock that rotates barley and canola. In-furrow treatments were applied using a split boot system and the seeding depth was 20-30mm. A dry start to the season led to a decile one for disease in 2020. Low pressure combined with stressful crop conditions were not conducive for a fungal environment.

PRE SEEDING

Pre-seeding Knockdown – 5/5/2020: Glyphosate 1L/ha, Goal 60ml/ha, Hammer 400EC 15ml/ha, Wetter1000 0.2%, Ammonium Sulphate Herbicide Adjuvant.

Nitrogen- 15/5/2020: Flexi N 80L/ha.

Immediately Pre seeding – 15/5/2020: Paraquat 1L/ha, Treflan 2L/ha, Metribuzin 750WG 125g/ha, Conquest Alpha Forte 250 SC 40ml/ha.

Seed and In-furrow treatments 15/5/2020: As per trial design.

SEEDING 

Seeding- 15/5/2020: Barley RGT Planet 64kg/ha, Double Phos 132kg/ha, Sulphate of Potash 50kg/ha.

POST SEEDING 

Nitrogen Top-up- 24/6/2020 – Flexi N 80L/ha.

Z32 Application Sprays – 13/8/2020: As per design.

Z32 Bumper Spray – 17/8/2020: As per design.

Key Findings

  • A decile 1 year for disease resulted in no significant difference between treatments with respect to yield, however, there were numerical differences.
  • Conical snail damage late September, snails moving up the canopy and feeding on the upper leaves – were inverting the green leaf retention results.
  • SD Systiva 150ml/100kg fb Z31 Radial 600ml/ha was the most effective treatment, reducing infection of FL-2 by 18% compared to the control. However, this was not significantly different to most of the treatments (including the control) due to low disease pressure.
  • Z31 Topnotch 400ml/ha with SD Systiva fb FL Radial and Z31 Topnotch 400ml/ha with SD Systiva fb FL Aviator X-Pro reduced disease by 16% and 17% respectively compared to the control.
  • Level of disease pressure must be taken into account when deciding whether to use fungicides
  • This trial indicates the benefits of well-timed treatments. Be it seed treatment with a follow up spray or a Z31 foliar spray followed by a Flag leaf foliar spray.
  • Crops are generally considered at risk of yield loss when SFNB is easily found on all plants and the infection affects more than 10 per cent of the leaf area. Rainfall during late winter and spring favours SFNB infection and will increase potential losses. Therefore, the 2020 season is a prime example of when not to spray, in order to gain the most economic value from your crop and your system.

  2. How does Syngenta’s new seed dressing (SD) compare to standards in the control of crown rot?
  3. How does Vibrance/Syngenta’s new seed dressing (SD) compare to standards in the control of crown rot?
  4. Are treatments safe to the crop?

Background

The trial was sown on the 19th of May in Beacon, WA. The site has a history of crown rot.

PRE-SEEDING

Key Findings

  •  Emergence counts conducted at 14 & 28 DAS saw no significant differences between treatments (P>0.05).
  • Crown to first node discoloration incidence and severity percentage ratings were low due to a lack of disease in the crop.
  • Crown discoloration was observed only in the untreated, Vibrance 360ml/100kg and Rancona Dimensions 320ml/100kg.
  • SD seed treatment stand alone at 1x, 2x and 3x rate as well as SD 1x + Vibrance all compared well to standards in the control of crown rot.
  • The addition of Vibrance to SD  improved disease control.

Key Findings

  • Sable-X 1.2g/kg and Bombardier 2L/ha in furrow caused significantly greater crop emergence than the untreated control.
  • Visual vigour ratings 15DAAB saw an increase of 5% in plant vigour of Bombardier 2L/ha; fb Bombardier 2L/ha and Bombardier 4L/ha respectively.
  •  No significant difference in yield between treatments compared to the control.
  • Sabel-X achieved 15.8% higher yields than control on average.
  • Early emergence and vigour ratings did not translate into yield increases for both Bombardier treatments.
  • Plants response to the N decreased in low rainfall.
  • Wheat yields were lower than expected, around 2.5 t/ha, as a result of low growing season rainfall.
