BIOLOGY AND INTEGRATED CONTROL OF RED RICE

Objective



Red rice is considered the most troublesome weed of the European rice fields. In these cultivation areas the weed showed in the last years a growing spread, particularly after the diffusion of less competitive cultivated varieties. In these conditions weed infestations have been favoured by the use of rice seed polluted by grains of wild plants and because of the lack of successful means of control.
Rice growers are often induced to rotate rice with other crops but in most situations saline and I hydromorphic soils limit remarkably this possibility. The project proposal originates from the pressing need to find effective and environmentally I friendly methods of its management. The importance of this research has been, also, stressed by the Concerted Action - EC-DG Vl (no AIR3-PL93-2518 - Quality and Competitiveness of European Rices".
This research project has, in particular, the following aims:
1 ) to characterize and identify red rice biotypes through molecular markers and to assess their relations to the crop as well as their ability to be a weed.
2) to find out simple diagnostic tests for red rice grain identification in rice seed.
3) to evaluate the competitiveness of the most cultivated rice varieties with main red rice biotypes at different cultural conditions.
4) to study the red rice population dynamics according to different environmental and agronomical conditions.
5) to assess red rice emergence in relation to tillage system, straw and water management.
6) to test the effectiveness of mechanical and chemical means against red rice before and after rice planting, and in rotational crops. 7) to develop and test strategies of integrated weed management based on the findings acquired by the studies on the biology and the results of specific control measures.
Such objectives will be pursued by: 1 ) characterizing red rice biotypes using molecular markers; 2) studying biological red rice behaviour; 3) inventorying and evaluating measures of the weed control; 4) testing the combination of agronomical practices and direct and indirect control measures giving the best sustainable management of the weed. The results of the research proposed will provide susbstantial benefits from a scientific, technical and environmental point of view. The research fits with the objectives of the FAIR workprogramme (areas 4.1.1-4.1.2-4.4.1) and with the policies of the E.U. regulation 2078/92 in the area of the weed management.
