小麦全蚀病(Ophiobolus gramis graminis Saoc.)是我省小麦上的一种毁灭性病害,六十年代在全国只有个别省份发生。1975年我区组织技术力量对小麦全蚀病全面普查,发现全蚀病虽已传入我区,但只有个别地方零星发生,危害不重。1982年发现个别地块、地段发病趋向严重。由于菌源积累,气候条件适宜,致使该病于1984年暴发为害,对小麦生产造成威胁。为了掌握此病在我区的危害程度及发生规律,我们于当年六月中、下旬前后到庆阳县温
Ophiobolus gramis graminis Saoc. Is a devastating disease on wheat in our province. In the 1960s, only a few provinces across the country were affected. In 1975, our district organized technical forces to conduct a comprehensive survey on wheat eclipse and found that although all eclipses have been introduced into our district, only a few places have sporadically occurred, which is not harmful. In 1982 found that individual plots, lots tend to be more serious. Due to the accumulation of bacterial sources, suitable climatic conditions led to the outbreak of the disease in 1984, threatening the wheat production. In order to grasp the extent of the disease in our area and the occurrence of the law, we in mid-June, late to Qingyang County temperature
