The invention belongs to the field of chemical control of growth of traditional Chinese medicines, and particularly discloses an application of pendimethalin in seedling controlling of Trichosanthes kirilowii Maxim. The invention further discloses a method for controlling growth of Trichosanthes kirilowii Maxim seedlings with pendimethalin, that is, when vines of Trichosanthes kirilowii Maxim growto height of 2/3 or higher of a rack, pendimethalin emulsifiable diluents are sprayed to leaves of Trichosanthes kirilowii Maxim once every 20-30 days, and spraying is stopped in mid-August. The method has good seedling control effect on Trichosanthes kirilowii Maxim, the leaves above the ground after seedling control are not closed, and the vines at the top of the rack are not wound; secondly, with the method, the yield of radix trichosanthis can be increased by 20%-31.2%, and the yield increase effect is extremely remarkable. Besides, the radix trichosanthis produced with the method has good quality, and quantity o
