Abstract The mother-plant-cutting technology（MPC）applied during chufa tillering stage in fields have
been applied and extended in chufa producing areas in Zhejiang Province. The detailed procedure is when the tiller
number reached 6-7 plants，cut all leafy stems of mother plant above the ground by a sickle digging into 1-5 cm
under the soil surface. The cut debris was moved out from the fields. Compared with the mother-plant uncut plant，
the stem blight rate of mother-plant-cutting plant was reduced by 4.6-7.4 percentage point，and the disease index
（DI）was reduced by 2.2-3.9. The number of inefficient tiller decreased by 2.3-7.5 plant per m2. Besides，the
yield was increased by 15.5%-20.9%，and the number of corm increased by 17.0-25.2 per m2. Mother-plantcutting
technology is a simple and high efficient innovative technology for chufa pathogen reduction and yield
increase.
