據(jù)檢驗檢疫部門工作人員介紹，若大豆感染該病菌后，莖部形成凹陷的紅褐色潰瘍斑，潰瘍部組織位表皮剝落、易碎，嚴(yán)重者整株死亡?！?0世紀(jì)50年代美國中北部地區(qū)曾發(fā)生過該病害，80%的大豆植株受害，產(chǎn)量損失達(dá)50%，造成嚴(yán)重的經(jīng)濟(jì)損失。”據(jù)悉，1983年，美國因此病造成的損失估計高達(dá)5900萬美元，“一旦該病菌傳入，將會給中國大豆種植帶來嚴(yán)重經(jīng)濟(jì)危害。”
為保護(hù)我國生態(tài)安全，防止有害病菌傳播，南沙檢驗檢疫局表示，他們將嚴(yán)格實施進(jìn)境大豆從口岸裝卸、運輸、加工等全鏈條的檢疫防疫監(jiān)控，加大進(jìn)境糧食檢疫監(jiān)管力度，尤其加強(qiáng)對問題大豆的后續(xù)監(jiān)管和處理。
