No one method of preparation for shipping of plant materials will assure their satisfactory arrival in the laboratory. Following the suggestions given below will ensure that specimens will be received in good condition. Specimens completely desiccated or in advanced states of decay and those which arrive without supporting information will have to be discarded. This represents time and labor wasted for the sender and personnel at Louisiana State University. Findings reported are necessarily based on examination of the material submitted.
Some diagnoses require intensive studies.
Because the time devoted to individual specimens must necessarily be limited, reports, while reflecting considered opinion and best judgment, may not always be statements of established fact. Be sure to send plants showing early stages of disease. Send sample of soil and feeder roots in plastic bag. Seal to avoid loss of moisture. Select specimens from recent infestations.
