摘要
芒果蒂腐病是广东省芒果贮运期仅次于炭疽病的重要病害,根据病原菌形态鉴定、培养性状,致病性测定及症状观察,蒂腐病主要是由DothiorelladominicanaPet.etCif、BotryodiplodiatheobromaePat.和PhomosismangiferaeAhmad3种真菌引起的,其中D.dominicana引起的烂果约占总蒂腐病烂果的50%,D,dominicana和P.mangiferae是国内新记录。经3年时间对4种药剂、多批次的采后试验结果,50%施保功500倍和40%抑霉唑特克多混剂400倍常温(29℃)浸果2min,贮藏第15天,防效均达71.05%,而2种苯并咪唑类药剂52℃热药处理,防效仅为63.16%~68.42%,较上述药剂的低,且热药处理方法在生产上较难应用。
Mango stem─end rot is an important disease next to anthracnose in GuangdongProvince. According to the morphological,cultural,pathogenetic and symptomaticstudies, the disease was caused by three fungi: Dothiorella dominicana Pat. et Cif.Botryodiplodia theobromae Pat. and Phomopsis mangiferae Ahmad. The first ispredominant, about 50%of total fruits infested by stem─end rot,D. dominicanaand P. mangiferae are two new records in China. After the experiments of chemicalcontrol in post─harvest for 3 years(1990~1992),mangoes dipped in the diluted solution(lg a. i./L of Sporgon(wp 50%) or in the diluted solution (lg a.i./L)of the mixture(Imazalil + tecto)(40%) for 2 min,and stored in temperature(29℃ ) for l5 days, thecontrol effect was 71.05 %。The control effect of hot water (52 ℃) treatment withbenzinlldazoles was 63.16%~68.42 %,but this method is quite difficult to applyand extend in practice in present time.
