正确预测马铃薯晚疫病(Phytophthora infestans De Bary)的发生和流行时间对于有效防治晚疫病具有重要意义。因为在适宜温度下晚疫病病原菌分生孢子的形成和萌发以及后来侵染植株需要足够的叶片持续湿度,因此,通过分析当时的气象信息能够预测病害的发展。这一结论是在该问题的许多研究基础上 Proper prediction of the occurrence and prevalence of Phytophthora infestans De Bary is of great significance for the effective control of late blight. Because the formation and germination of the late blight pathogen conidia at a suitable temperature, and subsequent inoculation of the plants, require adequate leaf continuous humidity, the development of the disease can be predicted by analyzing the prevailing weather information. This conclusion is based on many studies of the issue
