The investigation on the efficacy of pre-emergent herbicides on morphological parameters of gladiolus (Gladiolus grandiflora L.) under hill zone of Karnataka was conducted at experimental block in the Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (under University of Agricultural and Horticultural Sciences, Shivamogga), during 2019-2020.The experiment comprises of twelve treatments replicated thrice in Randomized Complete Block Design. The results revealed that the maximum sprouting per cent (100 per cent), number of shoots /corm (1.83), plant height (70.50 cm) recorded in weed free treatment. While the maximum number of leaves per plant (10.20), leaf area, leaf area index (1023.93 cm2 and 1.72, respectively), chlorophyll-a, chlorophyll-b and total chlorophyll content in leaves (1.57, 0.79 and 2.36 mg/g, respectively) recorded with pre-emergence application of pendimethalin at 1.0 kg a.i./ha. Whereas the minimum sprouting per cent (90.89per cent), number of shoots /corm (1.26), plant height (51.20 cm), number of leaves (5.70), leaf area, leaf area index (403.99cm2 and 0.71, respectively), chlorophyll-a, chlorophyll-b and total chlorophyll content in leaves (0.82,0.28 and 1.10 mg/g, respectively) are observed in weedy check condition.
