Device and method for detecting plant pathogens

A method for in-situ detection of microorganisms or plant pathogens directly at a site of soil or water employing a detection device comprising:

• placing a support member of the detection device in contact with the soil or water, wherein the support member contains a plant pathogen chemoattractant absorbed by the support member to attract the microorganisms or the plant pathogens in the soil or water into the detection device, wherein the support member is the only part of the device inserted into the soil or water and insertion is located in the soil or water at a location of plant growth or a location being considered for plant growth;
• and
• detecting the microorganisms or the plant pathogens directly at the site of the soil or water after placing the support member of the detection device in contact with the soil or water;
• wherein the support member comprises material that allows the microorganisms or the plant pathogens to flow within the detection device from one end of the support member to another end of the support device via a filter positioned within the detection device that selectively allows only the microorganisms or the plant pathogens to be detected to reach a culture medium also within a container and connected to the filter;
• and
• wherein the culture medium contains a plant pathogen chemoattractant which attracts the microorganisms or the plant pathogens, and the culture medium further contains a detection means capable of detecting the microorganisms or the plant pathogens.
