草莓味道鲜美，市场价格也较高，因此种植草莓的农户也越来越多。随着种植结构的不断调整，草莓病虫害也越来越严重，尤其死棵现象让许多种植户头疼。导致草莓死棵的主要病害有根腐病、枯萎病、黄萎病、青枯病这四大病害。
草莓死棵原因分析：
一、肥害
草莓吸肥但不耐肥，因此施肥应少量多次，不少农户基肥使用量大或者使用未腐熟有机肥，定植后浇水，造成烧根现象死苗。定植后不发新根或新根发生很少，心叶不生长，然后根系变褐腐烂，全株死亡。
二、红中柱根腐病：发病初期草莓根系的中心株呈红色或淡红色，以后变为黑褐色，腐烂，地上部基部叶的边缘先变成红褐色，然后逐渐向上凋萎死亡。地温在20度以下时，从草莓的根部侵染，地温在10度左右且湿度大时发病重，地温超过25度，土壤水分多，也较少发病。因此，春秋两季低温多雨容易发病。
