敌克松即对二甲氨基苯重氮磺酸钠,是一种种子和土壤杀菌剂,反复施用,能防治温室油梨实生苗的根腐病,也能防治大田油梨树的根腐病或减轻病情。油梨根腐病病原菌是肉桂疫霉菌(Phytophthora cinnamomiRands)。在人工接种病原菌的土壤上,敌克松施用量与接种量之比,对油梨苗生长和发病严重度都有明显影响。病原菌在500P.p.m.的敌克松中,最多存活20天,随培养基而定。敌克松有抑制孢子形成的作用,5p.p.m.的敌克松就能使病菌孢子囊和厚垣孢子的形成减少
Nocturne is p-dimethylamino benzene sulfonazide sodium, is a seed and soil fungicide, repeated application, can prevent and cure the root rot of greenhouse pear seedlings, but also can prevent the root rot of field pear tree Or reduce the condition. The root rot rot pathogen of avocado is Phytophthora cinnamomiRands. In the artificial inoculation of pathogen bacteria, the ratio of the dose of Aegiceras corniculata inoculation, the growth and severity of the avocado seedlings have a significant impact. Pathogenic bacteria in 500P.p.m. of the enemy grams of pine, the maximum survival of 20 days, with the medium may be. The enemy Kesong inhibition of spore formation, 5p.p.m. Of the enemy Cortex can make the bacteria sporangia and chlamydosporine formation decreased
