Common mallow, Malva neglecta with fast growing potential and its broad leaves is one of most hazardous weeds, which compete with saffron. In order to find a suitable herbicide, the field experiments were conducted during 2005–2006, at the Agricultural Research Station of Zahak–Zabol. The experiments were designed as a randomized complete block with six treatments and three replications, in a six years old saffron field. The herbicide treatments were scheduled after harvesting of saffron flowers, when the weed was in 3–5 leaf–growth stage. The treatments were included: Ioxinil (EC 22.5 %) at 3L\ha, Bromoxinil + MCPA (EC) at 1.5 L\ha, Oxyfluorfen (EC 24 %) at 1.5 L\ha, 2,4–D + MCPA (SL 67.5 %) at 2 L\ha, Metribuzin (WP 70 %) at 0.75 Kg\ha and control (without spray). The efficiency of the herbicides were calculated using the standard method EWRC at 10, 20 and 30 days after spraying and weed dry weight was measured in 30 and 60 days after spraying. The results showed that Metribuzin (without loss in saffron) controlled common mallow completely. This treatment prevented re–growth of weeds the end growth season (saffron leaves become dry natural). Treatment of Oxyfluorfen completely controlled the weed, but after 10 days common mallow and other weeds, Vicia villosa, Malcolmia africana and Hordeum sp. were appeared gradually. Oxyfluorfen was induced the necrotic damges on saffron leaves, which were tolerable for the plant. The treatment 2,4–D + MCPA was severely damaged the saffron, which appeared as chlorosis from the bases and their elongation (10cm longer than control).<\div>

Saffron (Crocus sativus) is the world’s most expensive spice, and a poor competitor of weeds. It grows very slowly and is a short–statured crop. So, dense weed growth at any stage of crop growth will have an adverse effect not only on its yield but on quality of the produce as well. The major weeds normally infest a saffron crop are hoary cress (Cardaria draba), downy brome (Bromus tectorum), bulbous blue grass (Poa bulbosa), hare barley wild barley (Hordeum spontaneum), redroot pigweed (Amaranthus retroflexus) and Canada thistle (Cirsium arvense). Manual weeding and herbicide application are the two dominant approaches in controlling established weeds in saffron. But in terms of expenditure manual weeding is costly and time–consuming. Herbicide application is also a costly and non–ecologically sound method of weed control. The necessity of moving toward healthier environment and sustainable agriculture forces us to reduce herbicide application as much as possible. So in terms of integrated weed management (IWM) more attention should be paid to non–chemical weed control methods particularly physical, mechanical and crop–based approaches. But not much information is available on the efficiency of these non–chemical methods of weed control in saffron. So we decided to investigate these approaches of weed control in saffron that can be used for effective weed management while keeping environment safe.
