The occurrence of Pseudomonas corrugata in soil has been checked. Semiselective medium TNR (a modified SNR) permitted to isolate the causal agent of “tomato pith necrosis” from that source. The average soil population of the bacteria was 3.1 × 10 4 CFU × g of soil. P. corrugata was also isolated from plants sowed in the naturally infected soil. It was supposed that primary infections came from here.
