用经氢氧化钾部分中和的亚磷酸或用乙磷铝进行叶面喷施或土壤灌注能防治樟疫霉引起的油梨(Persea amerfcana)和印度油梨(P.indica)的根腐病。灌注磷酸可增加油梨疫霉根腐病害的发生,然而白云石灰岩、石膏或磷酸氢二铵对病害的发生没有影响。把部分中和的20％亚磷酸注入感染疫霉根腐病的7龄油梨树主干内,经过12个月病树可迅速恢复。用乙磷铝和10％的亚磷酸注射,以及给土壤中施入瑞毒霉都能减缓病害症状。
Phytophthora capsici-induced root rot of Persea amerfcana and P.indica by Phosphorus acid partially neutralized with potassium hydroxide or foliar application or soil perfusion with ethosilicate . Phosphoric acid infusion increased the occurrence of root rot in Phyllostachya pear, however dolomite, gypsum or diammonium phosphate had no effect on the occurrence of the disease. The partially neutralized 20% phosphorous acid was injected into the trunk of the 7-year-old avocado tree infected with Phytophthora capsici and recovered rapidly after 12 months of treatment. Injection with beta-aluminum phosphate and 10% phosphorous acid, as well as the application of refentanil to the soil, can reduce the symptoms of the disease.
