Effects of Sprouting,Cutting and Coating of Potato Seed on the Occurrence of Rhizoctonia solani Disease
Rhizoctonia solani seriously hinders the industrialization of potato production.This study investigated the effect of the factors on the control of Rhizoctonia solani disease by sprouting,cutting,quality treatment and coating treatments.The results showed that there was no significant difference in the proportion of disease grade between elite sprouted potatoes,whole seed and large tuber treatment,and unsprouted treatment.Similarly,there was no significant difference in disease grade between cut seed potatoes,small tuber treatment,and elite pre-coating treatment on June 17th.The incidence of grade three diseases was significantly reduced in the treatment of elite sprouted potatoes,whole seeds,and large tubers.Additionally,the disease grade in the treatment of pre-elite coated large tubers was notably lower than that in the treatment of coated small tubers on June 21th.Therefore,treatments involving coated seeds,sprouted potatoes,whole seeds,and large tubers can effectively reduce the degree of damage caused by Rhizoctonia solani disease in the early growth stage.These results also indirectly confirm that optimal germination conditions and rapid seed potato emergence can effectively reduce the damage caused by Rhizoctonia solani.In summary,implementing appropriate technical measures for quality control in potato production can effectively manage the disease and improve the quality of seed potatoes.
