甜菜丛根病是一种毁灭性的病害。五十年代至七十年代在意大利、日本、希腊、法国、德国、英国、芬兰、波兰等国相继发生为害。该病发生后,甜菜块根产量和含糖量大幅度下降,1964年意大利17个省区的15万亩甜菜因感染此病而失去使用价值,产糖量损失50—60％,致使部分糖厂关闭。1978年以来,我国甜菜主要产区内蒙的包头和呼和浩特也发现了这种病害,据报导,染病甜菜减产达43.8％以上,含糖率减少4—8％,已成为这些地区甜菜生产的一大威胁。
Beet root disease is a devastating disease. Fifties to the seventies in Italy, Japan, Greece, France, Germany, Britain, Finland, Poland and other countries have occurred in the victim. After the occurrence of the disease, beet root yield and sugar content dropped significantly. In 1964, 15 million mu of beet in 17 provinces and autonomous regions of China lost their value due to the infection and the sugar loss was 50-60%. As a result, some sugar factories shut down. Since 1978, the disease has also been found in Baotou and Hohhot, the major sugar beet producing areas in Inner Mongolia. It has been reported that yield reduction of beetroot reached 43.8% and sugar content decreased by 4-8%. It has become a big beet production in these areas Threats.
