病原体：白粉病;子囊菌，虽然还没有发现有性阶段;专性生物营养型。鉴定：表面菌丝体，菌丝透明;分生孢子梗直立不分枝;分生孢子椭圆卵形或杯形，22-46 x 10-20 m m，缺乏纤维蛋白酶体;分生孢子单个形成，很少形成2-6个分生孢子的短链;附着胞裂至多裂，很少乳头状。拟衣藻属，寄主范围：广泛，据报道可侵害13个科的60多种植物，特别是茄科和菊科的成员。症状：除果实外，植物的所有气生部分都有粉状白色病变。在严重的爆发病变合并和疾病是衰弱。农学的重要性：在温室番茄世界各地非常常见，但在田间生长的番茄作物的重要性日益增加。
Pathogen: Powdery mildew fungus; Ascomycete although sexual stage is yet to be found; an obligate biotroph.Identification: Superficial mycelium with hyaline hyphae; unbranched erect conidiophores; conidia, ellipsoid-ovoid or doliform, 22-46 x 10-20 m m, lack fibrosin bodies; conidia formed singly, rarely in short chains of 2-6 conidia; appressoria lobed to multi-lobed, rarely nipple-shaped. Pseudoidium species.Host range: Broad, reported to attack over 60 species in 13 plant families, particularly members of the Solanaceae and Curcubitaceae.Symptoms: Powdery white lesions on all aerial plant parts except the fruit. In severe outbreaks the lesions coalesce and disease is debilitating.Agronomic importance: Extremely common in glasshouse tomatoes world wide but increasing in importance on field grown tomato crops.Control: Chemical control and breeding programmes for disease resistance.
