红三叶草植株生长在温室里盛育取自栽培者试验田的土壤的盆中(20℃),这些试验田种植的红三叶草一直难以持久。用平板培养分离技术研究了由麦他莱克西尔(metalaxyl)和苯菌灵的混合物(每公斤种子各用1.5克)处理过的种子而长成的植物的真菌侵染情况,用麦他莱克西尔(metalaxyl)(0.15克/米~2)和苯菌灵(1.0克/米~2)的混合物浸淋土壤但未经处理的种子而长成的植物的真菌侵染情况以及其种子和土壤均未经处理的植物的真菌侵染情况。用杀菌剂处理种子和浸淋过的土壤,使出苗增加并防止出苗后的猝倒病。终极腐霉和一个未经鉴定的球形孢子的腐霉是从未处理的患猝倒病的幼苗的根部分离出来的。分离的
Red clover plants were grown in pots (20 ° C) in soils grown in greenhouses from the soil of the cultivators’ experimental field and the red clover grown in these fields had been hard to sustain. The fungal infestation of plants grown from seed treated with a mixture of metalaxyl and benomyl (1.5 grams per kilogram of seed, respectively) was studied using a plate culture separation technique with Metalace The fungal infestation of plants grown from a mixture of metalaxyl (0.15 g / m ~ 2) and benomyl (1.0 g / m ~ 2) soaked in soil but untreated and their seeds and Fungal infestation of untreated plants in soil. Use germicides to treat the seeds and the soaked soil to increase emergence and prevent post-emergence damping off. Pythium ulopsis and an unidentified spheroplast were isolated from the roots of untreated damping-off seedlings. Detached
