It has become increasingly difficult to combat wild rice over the years as its morphological characteristic become closer to those of cultivated varieties because of strong selection pressuredue to long and careful weeding and possible natural hybridization with cultivated varieties. Effect of red rice (Oryza nufipogon Griff.) I. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. In temperate climates, start indoors, preculture. Rojas M; Agnero R, 1996. Oryza rufipogon, etc ; Magnaporthe oryzae; Oryza sativa; blast disease; disease control; fungi; genetic background; greenhouses; ... species of the genus Oryza were carried out using one- and two-dimensional gel electrophoresis for variation in their seed proteins for interrelationships of these species. A new approach to chemical control of wild and red rice is the use of herbicide-tolerant crop cultivars, which can be safely treated with otherwise non-selective herbicides such as glufosinate (Sankula et al., 1997).

When the wild rice seedlings reached the 3-4 leaf stage (95% of seeds in the 0-4 cm soil layer had germinated), a mixture of paraquat and oxadiazon was applied. Scale bar = 1 mm. A geographical atlas of world weeds. As of today, the wild variety Oryza rufipogon is still at home in wetlands of tropical and subtropical Asia (Burma, Thailand, Laos, southern China and Korea). and Indonesian red rice.

Although thiobencarb has been recommended for use on O. rufipogon in rice, it is recommended that the crop seed be treated with a protectant or antidote, such as NA (1,8-naphthalic anhydride), as a safeguard (Wirjarhardja and Susilo, 1979; Smith and Hill, 1990).

Lorenzi, 425 pp. The distribution in this summary table is based on all the information available. Since Ashina flowers 2-3 weeks earlier than Johra-dan, weeding of Johra-dan can be easily done after harvesting Ashina (Morishima et al., 1991).Salimath (1921) recommended rotating different rice cultivars with different coloured stems. (1987) recommend the use of certified seed, regular removal pre- and post-flowering and cultivation of purple-leaved cultivars continuously for 2 or 3 years for the control of wild rice.

Chemicals are more commonly used pre-sowing to destroy the rice weed before the susceptible crop is present, for example, chemicals such as metolachlor either alone or tank mixed with trifluralin, pendimethalin, metribuzin or imazaquin are pre-sowing treatments recommended by Smith and Hill (1990).
