Abstract

In last time gardens are often at the dangerous of viruses and bacteria infections. To preserve not only the coming harvest, but, in generally, to provide stability and growing horticultures the development of new generation of the analytical techniques for remote express screening vegetative state arrays and direct control of the appropriate infection if appearance of its maybe expected on the basis of previous surveys are very actually and important. For continuous monitoring we propose the application of the complex of the optical analytical devices as “Floratest” and “Plasmatest” (both produced in Ukraine) which is able to control step by step general situation with vegetable state and verify concrete situation with infection. General screening is accomplished on the control of the intensity of chlorophyll induction (IChF), namely, registration of so called Kautsky curve which testifies about physiological mechanisms of energy generation, accumulation and effective ways of its realization in cells. The measuring may be done by direct way on the number of individual vegetables and remote screening of massive with transferring registered signal direct in the laboratory. Next step of control connected with the application of the surface plasmon resonance (SPR) based immune biosensor which is able to determine concrete bacteria (for example, Erwinia amilovora) with the limit detection about 0.2 μg/ml, the overall time of the analysis within 30 min (5 min of the duration of one measurement). The traditional ELISA-method showed the sensitivity to this pathogen about 0.5 μg/ml, overall time of the analysis several hours and obligatory using additional expensive reagents.
