TPCP Services

Services offered to members include the following:

 

Maintenance of an active and reliable Diagnostic Laboratory.

Diagnostic services of the TPCP function through foresters submitting samples to the programme for analyses. Such samples are usually received after discussion between research staff and the foresters concerned, so that appropriate material is submitted. Isolations for pathogens are conducted using state of the art techniques from plant tissues, soil and from water samples. Potential pathogens are often also tested for their ability to cause disease. An extensive culture collection including tree pathogens collected in South Africa during the course of the past 15 years is also maintained, such that comparative studies and pathogen variation can be studied in the longer term. Insect pests are also identified where possible, or sent to experts for identification in the case of uncommon or new pests. Advice is provided to foresters based on these investigations and identifications.

 

Contacts for the diagnostic clinic and information for collecting samples.

 

A research programme focused on pests and diseases of priority to members.

Research on pests and diseases of pine, eucalypts and wattle is conducted by students and permanent staff of the TPCP in modern laboratories specifically designed and equipped for tree protection research. Modern equipment for basic plant pathology and entomology research, as well as through the application of molecular biology techniques, is used in an effort to produce results equivalent to, and in some cases even better than those emanating from similar programmes elsewhere in the world. Research on diseases includes the identification of new pests and pathogens and studies on the biology of important pests and pathogens, specifically required to develop strategies to avoid losses. For example, through determining periods of spore release in Sphaeropsis sapinea, it has been possible to provide advice on suitable times for pruning of pines. Other priorities are to develop and implement techniques for rapidly screening species and clones for resistance to disease. Screening techniques include inoculation under greenhouse and field conditions as well as those making use of various physiological and molecular techniques. Research into a variety of disease control strategies including cultural, chemical and biological control also forms a significant part of this programme.

 

Monitoring of pests and diseases to gain a perspective of their relative importance.

An important component of the TPCP is to monitor pest and disease development in plantations, in permanent sampling plots and through country-wide surveys. Data derived from these studies ensure the early discovery of new pests and diseases and also lead to a long term perspective on the importance of various pests and diseases.

Education of field foresters and students.

Regular training courses for field foresters are provided and these ensure that knowledge and technology derived from research in the TPCP is transferred to the plantation level. In addition, forestry students are provided with lectures in the field of tree protection. Postgraduate students undertaking research in this field also ensure long term capacity building in this field.
