葡萄白腐病病菌分生孢子在1%葡萄糖液中萌发率为98.1%,在5%葡萄叶浸出液中萌发率为99.5%,在蒸馏水、雨水、地面泥水中未见萌发;分生孢子在室内自然干燥条件下可存活30～40天。植株病残体(果实)在室温干燥条件下保存24个月,分生孢子仍能正常萌发。病害分离菌在4℃存放120天,萌发率仍有30.8%,接种33种葡萄栽培品种,仅山葡萄(Vitis amarent)未发病;较抗病的有66-22-6、66-22-19.400倍乙磷铝、1∶0.5∶240波尔多液抑制分生孢子萌发率分别为73.1%和86.4%,其它药剂均在18%以下;退菌特、托布津、多茵灵、代森铵、粉托合剂,抗菌素401抑制菌丝生长的效果高达100%;粉锈灵、福美砷、乙磷铝亦可达到90%以上,标准药剂波尔多液为99.4%.
The germination rate of grape white rot pathogen conidia was 98.1% in 1% glucose solution and 99.5% in 5% grape leaf leachate, and no germination was found in distilled water, rainwater and groundwater; conidia were indoors Natural dry conditions can survive 30 to 40 days. Plant disease residues (fruit) stored at room temperature for 24 months under dry conditions, the conidia can still germinate. Disease isolates stored at 4 ℃ for 120 days, the germination rate is still 30.8%, inoculated 33 kinds of grape cultivars, only Vitis amarent is not disease; 66-22-6,6 66-4-19 times more resistant to disease Borneol, 1: 0.5: 240 Bordeaux mixture inhibited the germination rates of conidia to 73.1% and 86.4%, respectively, and the other agents were all below 18%. The antibacterial agents, topiramate, doxylamine, Mixture, antibacterial effect of mycelium 401 inhibition of mycelium up to 100%; powder rustling, Fumei arsenic, phosphorus and aluminum can reach more than 90%, the standard pharmaceutical Bordeaux mixture was 99.4%.
