Integrated Management of Red Rice in Wet Seeded Rice Production

Abstract

The integrated management technology in wet seeded rice production trial was conducted in the farmer's field, infested with the vigorous dissemination of red rice during March-October 2005. The main objective was to decrease the amount of red rice which has spread out in the field and to decrease of the accumulation and the broadcasting of red rice seeds in the soil. The integration of soil resting in dry condition for 4 weeks namely, induction of red rice seeds to germinate and to eliminate using the good quality of seed, and red rice stem or panicle cutting together with pretilachlor or alachlor or 2,4-D + thiobencarb application and was found as the effective technology. The red rice was found 0.11±0.05 – 0.60±0.30 panicle/m2 in the farmer practices. The decreasing percentage of integrated management red rice was 97.48-99.54 % when was compared with integrated management and the farmer practices (before experiment). The study of seed quality was found that the integrated management was contaminated with red rice 0.0005-0.0288 % by weight. This was shown that the grain was good quality and also can be produced as the multiple seeds, while the farmer practices was contaminated with red rice as high as 1.9125 % by weight.
