摘要
马铃薯晚疫病是发生最普遍和最具有毁灭性的真菌性病害。目前，利用化学农药防治晚疫病是一种有效的方法。本试验比较研究5种不同药剂对马铃薯的产量及品质的影响，结果表明，不同化学药剂对马铃薯产量及品质均有不同程度的影响；其中，喷施甲霜灵锰锌后，每公顷产鲜薯24t，比对照（喷清水）增产7．80t／hm^2。增产幅度为48．11％，大中薯率比对照增加18．03％。通过本试验的研究，筛选出经济、有效的马铃薯晚疫病防治农药和使用方法。
Potato late blight is the most widely and fatal fungal disease and it can be controlled effectively by pesticides at present. Hence experiments with 5 chemicals were carded out to compare their influence on yielding and quality. The results indicated that metalaxyl is the powerful chemical which can increase yielding 48.11% and quality 18.03% comparing to check. The main purpose of this experiment was to identify economic and practical chemical and related methods for potato production.
