Miravis Star Canola foliar fungicide

By South Stirlings

Objectives

  1. Evaluate Syngenta’s new foliar fungicide in canola, for the control of Sclerotinia.
  2. Compare and contrast with existing chemicals on the market.

Background

The trial was sown on the 25th of May in the South Stirlings region. A dry start to the season lead to a decile 1 year for disease and no Sclerotinia was detected at the site during the season.

PRE SEEDING

Early Knockdown -17/4/2020: Glyphosate 450 1.5L/ha, Oxyflurofen 240 EC 60ml/ha, Hammer 400 EC 15ml/ha, Kamba 750 200ml/ha, Wetter1000 0.2%, Ammonium Sulphate 1%.

Pre seeding knockdown- 27/4/2020: Glyphosate 450 1L/ha, Goal 60ml/ha, Hammer 400 EC 15ml/ha, Wetter1000 0.2%, Ammonium Sulphate 1%.

Key Findings

  • No visible evidence of Sclerotinia, however Blackleg ( Leptosphaeria maculans) was visible throughout the trial.
  •  No significant yield difference between treatments although all treated plots had numerically higher yields than the control. This could be due to the presence of Blackleg causing a slight yield decrease in the untreated control.
  • No crop damage from any of the treatments.

ILeVo Blackleg seedling control in canola

By South Stirlings

Objective

To demonstrate BASF’s new canola blackleg seedling treatment, against existing treatments on the market.

Background

Blackleg, caused by the fungus Leptosphaeria maculans is one of the most serious diseases of canola in Western Australia. This trial was sown on the 25th of May, at a site with previous history of Blackleg, in the South Stirling region. A dry start to the season correlated to a decile 1 year for disease. The area finished with a GSR of 400ml with the first major rainfall event in August.

PRE SEEDING

Early Knockdown -17/4/2020: Glyphosate 450 1.5L/ha, Oxyflurofen 240 EC 60ml/ha, Hammer 400 EC 15ml/ha, Kamba 750 200ml/ha, Wetter1000 0.2%, Ammonium Sulphate 1%.

  • No blackleg at 2 leaf crop stage and in the upper canopy throughout crop growth.
  • Significant difference between treatments for internal infection at windrowing, with the Ilevo treatment reducing internal infection by 50% compared with the control, but was slightly less effective than Maxim XL and Saltro Duo.
  • No significant yield differences between treatments, however, Ilevo treated plots yielded the highest by 100kg/ha.

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.

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.

  • 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.

  •  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.

  • All treatments containing Relfex IBS or PSPE provided significantly better control of broadleaf weeds.
  • No significant difference between plots applied IBS or PSPE.
  • Reflex tank mixed with a group C increased efficacy and residual control for up to 11 weeks after sowing.
  • Reflex 1500ml + Metribuzin 300g/ha had best residual control (96.3%) at 11WAS.
  • No crop effect was seen after IBS or PSPE application.
  • As a new group G herbicide, Reflex will go a long way to help growers control brassica weeds and rotate away from the ‘imi’ chemistry that has been heavily relied on over the years.

Mateno®️ Complete : Control of grass and broadleaf weeds in wheat

By Dumbleyung 2020, Dumbleyung Pre-Emergent Herbicides 2020

Company: Bayer

 Registration expected for ~2022. New mode of action suited to stubble retained systems. Likely: Flexibility to apply IBS or early post emergent with activity on a range of grass and broadleaf weeds.

 

Background:

The Mateno Complete trial was established at the David Grays AgroAdvantage trial site in Dumbleyung, WA. Herbicide applications included Incorporated by sowing (IBS) treatments, applied the same day as sowing with good incorporation and soil throw. The next main rain event occurred on the 17/18th June with 20mm recorded at the site using a field centric weather station. Wild Radish Raphanus raphanistrum and volunteer Bonito Canola were spread prior to spraying IBS treatments, to mimic a medium-high weed burden of approximately 8 plants/m2 (90% germ test). Mateno complete contains active ingredients; Diflufenican, Pyroxasulfone and a new MOA Aclinofen. Chemical groups F, K with Aclinofen to be decided.

 

 

Objective:

1. Demonstrate the crop safety of Mateno Complete in wheat when used as an IBS or EPE application.
2. Demonstrate the efficacy of Mateno Complete  on a range of weed species.
3. Compare Mateno Complete  to key competitors for crop safety and weed control.

Key Findings

IBS

  • Mateno Complete applied IBS had some activity on BLW also. 50-60%.
  • Mateno Complete performed significantly (P<0.05) higher than all other grass herbicides.
  • > 16 weeks residual effect on IBS applied plots.
  • No significant difference between Mateno low and high rates (P=0.05).
  • Good crop saftey.

EPE

  • Rapid burn down of 2-4 leaf BLW.
  • 16 weeks residual EPE applied plots.
  • Grass herbicide applied up front followed by Mateno EPE provided best control of both weed types.
  • No significant difference between Mateno low (750ml/ha) and high (1L/ha) rates (P=0.05).
  • Trifluralin fb Mateno low and high rates, Avadex fb Mateno performed equally as well.
  • Matching pre and EPE treatments together will provide best outcome for weed control and MOA rotation.
  • Transient crop bleaching due to Diflufenican (group F).
