酰基丙氨酸和乙磷铝可防治由芝麻疫霉菌(Phytophthora parasitica)和樟疫霉菌(P.cinnamomi)引起的菠萝心腐病及由樟疫菌引起的菠萝根腐病.用600ppm的酰基丙氨酸和1,200ppm的乙磷铝在种植前浸泡种苗有明显的防治效果; 用3.36～6.72公斤/公顷的磷酸(一种乙磷铝水解物)对心腐病也有明显的防治效果;同时,因它还可兼治根富病,从而促进植株的生长.温室研究表明,乙磷铝与磷酸在24小时内都可向下转移,故可防治根腐病.
Acylalanine and aluminum phosphate prevent pineapple heart rot caused by Phytophthora parasitica and P.cinnamomi and pineapple root rot caused by Campylobacter spp .. With 600 ppm of acylpropyl Ammonia and 1,200 ppm BEP had obvious control effects on soaking seedlings before planting. Using 3.36 ~ 6.72 kg / ha phosphoric acid (a kind of phosphorus phosphorus hydrolyzate) also had obvious control effect on heart rot, meanwhile, , Because it can also cure root cause of disease, thereby promoting the growth of plants.Greenhouse studies have shown that phosphorus and aluminum phosphate can be transferred down within 24 hours, it can prevent root rot.
