自70年代以来,玉米茎腐病[Colletotrichum graminicola(Ces.)Wils.]被认为是威胁美国北部玉米生产的病害之一。而病害对玉米产量影响的报道很少。Perkins(1979)通过健株与病株的产量比较,测定了炭疽茎腐病(ASR)对36个杂交种产量影响,其范围是从增产11％到减产17％。Keller等(1986)
Colletotrichum graminicola (Ces.) Wils. Has been considered one of the diseases that threaten maize production in the northern United States since the 1970s. The impact of disease on the yield of corn is rarely reported. Perkins (1979) compared the yields of healthy and diseased plants to determine the effect of anthrax stem rot (ASR) on the yield of 36 hybrids ranging from 11% increase to 17% decrease. Keller et al.
