Red rot caused by Colletotrichum falcatum Went is a serious stalk disease affecting production and productivity in sugarcane. Soil borne inoculum of C. falcatum serves as the major source of primary inoculum in disease epidemics and critically plays a key role in disease cycle. However, information on infectivity of the soil borne fungal inoculum on sugarcane varieties varying in disease resistance, sett germination and disease development is lacking. We have taken up detailed studies on the impact of this inoculum multiplied on sorghum grains on infection of planted setts on a set of 10 sugarcane varieties varying in disease resistance and disease build-up in the field with 11 different pathogenic isolates varying in their virulence. This study suggested a differential behaviour of soil borne inoculum of C. falcatum on vulnerability of sprouting buds, and probably, this primary infection may lead to C. falcatum adaptation in new host varieties.

不同抗病性甘蔗品种产红腐病炭疽菌的产菌行为。

炭疽菌引起的红腐病是严重的茎病，影响甘蔗的生产和生产力。贯叶连翘的土壤传播接种物作为疾病流行中主要接种物的主要来源，并在疾病周期中起关键作用。然而，缺乏关于土壤传播的真菌接种物对甘蔗品种的抗病性，定居萌发和疾病发展变化的信息。我们对这种接种物对高粱谷物的繁殖对种植的定居点感染的影响进行了详细的研究，该种植体在田间具有10种不同的抗病性和疾病积累的甘蔗品种，其11种不同的致病菌株的毒力也各不相同。这项研究表明土壤传播的棒状线虫接种物对 发芽芽的脆弱性有不同的行为，这种原发感染可能导致棒状线虫 适应新的寄主品种。
