Abstract

Sugar beet plants (cv. Arosa), susceptible to rhizomania, were grown in 144 soil samples taken from sugar beet fields in north and central part of Turkey in 2004. Incidences of Beet necrotic yellow vein virus (BNYVV) and Beet soilborne virus (BSBV) by ELISA and of their vector Polymyxa betae by root staining method were determined in bait plants. Some soil properties such as, texture, pH, organic matter, cation exchange capacity, electrical conductivity, lime (CaCO3) and exchangeable Ca, Mg, K and Na contents were determined. Sand content and pH values of the soils gave significant positive correlations with P. betae (0.177* and 0.164*, respectively). Lime (CaCO3) and exchangeable Mg contents had also significant positive correlations with soil pH. Increasing CaCO3 (0.189*) and exc. Mg (0.235**) content of soils induced BNYVV and BSBV infections respectively, transmitted by P. betae, due to their increasing effects on soil pH.

Highlights

The disease is caused by Beet necrotic yellow vein virus (BNYVV)
Beet soilborne virus (BSBV) may cause symptoms resembling rhizomania on sugar beet, but it frequently occurs in symptomless plants (Prillwitz and Schlösser, 1992; Koenig et al, 2000)
Relationships among the occurrence of soilborne viruses, their vector P. betae and the physico-chemical soil properties were investigated with direct coloration of bait plant root tissues for P. betae cystosori and ELISA tests for viruses

Summary

Introduction

Additional key words: bait plant test, BNYVV, BSBV, lime (CaCO3), soil pH. Contenidos crecientes en CaCO3 (0,189*) y en Mg intercambiable (0,235**) de los suelos indujeron infecciones de BNYVV y BSBV respectivamente, transmitidas por el vector P. betae, debido a su creciente efecto en el pH del suelo. BNYVV and Beet soilborne virus (BSBV) occurred together (Meunier et al, 2003).
