OUTLINE: This trial is investigating non-chemical options for weed control in pineapple fields.


METHODOLOGY:

The trial site (10 beds x 6 m) was left unsprayed with herbicide at planting. Alternative controls were applied in 2 bed x 2 m lengths creating 3 replicates of each treatment.

Treatments:

  1. Control – No herbicide
  2. Living mulch – Jap Millet
  3. Fine sugar cane mulch with polymer glue at 10%
  4. Coarse sugar cane mulch with polymer glue at 10%
  5. Coarse sugar cane mulch with polymer glue at 15%
  6. Herbicide with Stonewall (not randomised, grower practice for that block) directly adjacent to the trial site

The trial was planted on 5 December 2019 and received 14 mm of rainfall for December (6mm and 8mm).

On 22 January 2020, the image below was taken. The rainfall prior to the photo was recorded as:

  • 16/01 – 30 mm
  • 17/01 – 38 mm
  • 18/01 – 38 mm
  • 21/01 – 38 mm

Weed type and number will be measured in bed width x 1 m length rectangles in the middle of each treatment.

QUESTIONS / FEEDBACK:

How would you manage the living mulch in this trial?
