Hygiene in uninfested areas
Phytophthora dieback is most rapidly spread through human activity resulting in the movement of infested soil on vehicles, equipment & footwear. Therefore, this risk of spread of the disease creates a significant problem in the forestry, mining, extractive and construction industries. It is also a important issue for recreational bushland users such as four-wheel drives, off-road motor bikes, mountain bikes and bush walkers.
To prevent the spread of Phytophthora dieback into an uninfested area or within an area industries need to adopt strict hygiene measures. These hygiene measures don't need to be a hindrance, but they do require some forward planning. During the planning stage it is important to determine the risks associated with the operation. The table below outlines examples of activities that are high risk or low risk.
Prior to the commencement of the operation it is essential to conduct a survey to determine the distribution of the pathogen across the area of the operation. The results of the disease survey may indicate a number of scenarios, the site may be:
The management strategy will vary according to the relevant scenario. However, the greatest effort is required to ensure that sites that are currently uninfested remain free of the disease. The hygiene protocols for these four scenario's are shown in the table below.Table. Hygiene protocols to prevent the spread of Phytophthora dieback.
A small portable footbath are ideal when travelling in vehicles or organising field days for washing footwear. A footbath can be made from a plastic tub fitted with a rubber or plastic doormat, a scrubbing brush and a container of clean water. Either bleach, methyl spirits or the fungicide Phytoclean should be added to footbaths to sterilise the footwear or equipment being cleaned.
When practical a purpose built wash bay should be used. These wash bays would include:
When cleaning vehicles consider the following tips:
