引起番茄萎凋症的病害,有TMV烟草花叶病毒,青枯病枯萎病(J_1、J_3)灰色疫病,褐色根腐病、黑点根腐病、茎腐病、半身萎凋病等许多种。然自一九七五年以来,在促成半促成栽培中发生了一种与萎凋症状稍稍不同的受害植株。这种植株在刚要收获之前至第一果穗收获时急剧发生,萎凋株率为20%～30%,严重者达100%,平均有50～60%的果实不能收 The diseases causing tomato atrophy include TMV tobacco mosaic virus, gray blight of wilt disease (J_1, J_3), brown root rot, root rot of black spot, stalk rot, and half-body wilt disease. Since 1975, however, a victim plant slightly different from the wilting symptom has been found in the semi-induced cultivation. This plant occurs sharply just before the harvest to the first ear harvest, withered plant rate of 20% to 30%, in severe cases up to 100%, an average of 50 to 60% of the fruit can not be collected
