1975年兵库县大棚促成和半促成番茄上发现一种同已知病害症状稍有不同的枯萎,立枯状病害。其后,1978年又在大棚抑制和露地番茄上发现此病,并从病株根部高频度地检出了疫菌(Phytophtora),回接可高度侵染番茄,命名为“番茄根腐疫病”。该病先后发现于兵库县及其附近各县。由于该病在临收获前发病并迅速蔓延,因而严重威胁着番茄生产。
In 1975, Hyogo Prefecture greenhouse and semi-promoting tomato found a slightly different from the known disease symptoms withered, standing withered disease. Later, in 1978, the disease was found in greenhouse-suppressed and open-field tomatoes, and Phytophtora was detected at high frequency from the roots of the diseased plants, which were subsequently highly inoculated with tomato and named “Tomato root-rot disease ”. The disease has been found in Hyogo Prefecture and its nearby counties. The disease is a serious threat to tomato production due to its onset and rapid spread before harvest.
