SA04WB-01: Pest management

<< BACK TO R&D TRIALS


Research Site / Demonstration Number: SA04WB-01

Grower Collaborator: Littabella Pines

Location 1: South Littabella Road, Yandaran

Initiation Date: December 2018


OUTLINE: To develop and evaluate integrated pest management practices in pre-plant and post plant management programs targeting improve fruit yield and quality.


OBJECTIVES:

  • To investigate and improve the preventative pest management programs to pineapple fields.
  • To investigate and improve pre-plant pest management programs with focus on the improving soil biology and non traditional practices.
  • To undertake a cost analysis of the different pest management program vs standard practices.
  • To increase yield and fruit quality in plant and ratoon crops.

METHODOLOGY:

The research trial has been undertaken in co-operation with Littabella Pines Yandaran –  Bundaberg .  The location of the trial site is South Littabella Road, Yandaran.  The trial site has followed a previous crop of Smooth Cayenne which was taken to plant and ratoon crop.  The previous crop harvested in Spring 2018 with major issues of phytophthora root rot, nematode and black beetle / white grub.

The soil was prepared to standard industry conditions with good soil tilth, no crop residue and good soil moisture with a soil pH of 4.2.  Weather leading up to application had good rainfall with temperatures ranging from 20 – 30 degrees Celsius.

LAND PREPARATION

Ensure the soil is:

  • Tilth is fine
  • Free of trash / crop residue
  • Deep tillage has been undertaken using deep rippers twice – angled then straight.
  • Land has been levelled

Trial site – after planting (smooth cayenne).

PROGRESS REPORT

Current Progress: Site has been selected, land prepared, pre-plant applied, hilled and planted.  All treatments in the pre-plant have been applied and post plant applications have begun.

Issues Encountered: Nil

Other Notes: This site has been combined with SA03WB-03 as a complete program. $5,000 funding through the Growcom Hort 360 program has been acquired.
