- Abstract
Due to the fact that the rice production system is completely in aquatic environment, few but significant weed species have adapted to this system. Due to the effectiveness of Quinclorac active ingredient in the control of Echinochloa species, it is widely used in our country as in all countries where rice cultivation is carried out today. Especially in the Black Sea, Southern Marmara and partially Thrace regions where rice and vegetables are produced, as a result of the drift of this herbicide and the use of the water discharged in the rice pans on vegetables in 2020, serious phytotoxicity problems have been observed in some vegetables, especially tomato and pepper plants. In this study, practical application methods to reduce the drift risk of Quinclorac used in rice cultivation areas were investigated in order to protect both the rice farmers and not to victimize the vegetable producers. Within the scope of the project, with the trials established in Thrace, Southern Marmara and Black Sea Regions, the amount of residues in the water discharged from the rice fields following the Quinclorac application, depending on time, were determined and the phytotoxicities caused by the use of these waters in tomato and pepper cultivation were determined. Following the Quinclorac application, the Quinclorac residue, which was found as 0.01 ppm in the first 3 days in the water samples discharged from the rice fields depending on time, later fell below the detectable limit. This situation has shown us that vegetable irrigations made or likely to be done with the water drained from the rice pans will not create a phytotoxicity 5 days after the application. Again, in all applications in which the phytotoxicity of Quinclorac residue amount in water on tomatoes and peppers was tried to be determined, it was revealed that even doses 1000 times less than the application dose of Quinlorac active substance completely killed both tomatoes and peppers.
