Gladiolus (Gladiolus hybridus Hort.) belongs to the family Iridaceae. It is one of the most important ornamentals for cut flower trade in India and abroad. The importance of gladiolus as cut flowers is increasing day by day in domestic as well as international market. Weed is the most important biotic constraint for realizing higher productivity of gladiolus. Weeds compete for water, nutrients, space and light resulting in reduced flower yield and increased threat of serious insect and disease problems. Weed is also one of the most important yield limiting factors and significantly reduces the yield. Even with a low infestation of weeds, these should be controlled throughout the crop growing season. However, the most critical period for crop weed competition is first six weeks after planting of crop. During this critical period, weedings essentially required by chemical, nonchemical means or in integrated manner. Therefore, timely weed control at early stage is imperative for realizing desirable level of productivity. The use of herbicides offers selective and economic control of weeds right from the beginning, giving crop an advantage of good start and competitive superiority. Pre-and post emergence herbicides may also be viable option to control the weeds. Manual weed control is effective, if done frequently, but, it is very expensive. Hence, a successful integrated weed management program utilizes mulching or a combination of chemical measures, taking into consideration labour costs and availability of materials is the best way.
