Completed project
Scale and mealybug management options for lychee growers - an extension toolkit (LY20001)
Publication date: March 17, 2021
Delivery Partner: Queensland Department of Agriculture and Fisheries
This investment, which ran from 2021 to 2023, delivered an extension toolkit for lychee growers on how to manage scale and mealybug pests effectively.
The project team surveyed lychee orchards across key growing regions during two growing seasons to gain an overview of the scale and mealybug problem, including collection of data on the diversity of these pests and what grower control practices are currently being used.
The information collected was developed into a grower manual and informative shed poster as an extension tool for lychee growers. Topics covered include scale and mealybug identification, biological predators, scale pests identified during the farm surveys, current pesticide management options, post-harvest management using high pressure sprays and further information links and references.
The toolkit will help lychee growers understand:
Recommendations arising from the project include:
A shed poster, summarising the toolkit has also been produced. This will be printed and mailed out to growers to act as an easy reference “best-bet” management source. The accompanying management toolkit will be available for download on the Australian Lychee Growers’ Association website.
The project findings have been comprehensively promoted to industry through several mechanisms including one on one farm visits, presentations at industry meetings, and articles in the industry magazine Living Lychee.
