A research on determination of exceedence factor on environment of pesticide coated corn seeds

Cereals have an important place as nutrients. Corn, which is a hot climate cereal plant, has the highest planting area in the world after wheat and paddy. It comes after wheat and barley in terms of cultivation area in our country. In this study, the effect of pesticides covered on corn seeds on the environment was examined. In the study, 10 active substances (azoxystrin, chloraniliprole, cyantraniliprole, flubendiamide, fludioxonil, ipconazole, metalxyl, metalxyl-m, prothioconazole ve thiabendazole). Some environmental indicators such as birds, bees, ground worms, permanence in soil and infiltration of underground waters of these active substances were used in determining the threshold values. As a result of the analyzes; 10 effective substances used in the study; In the category of 2 active substances for birds (chlorantraniliprole and cyantraniliprole) for birds, the risk value is the R2 category of 1 active substance (flubendiamide) in the category of 1 active substance for bees, 4 active substances in the soil (azoxystrobin, chlorantraniliprole, flubendiamide ve thiabendazole) in the R4 category, 1 effective substance (ipconazole) has risky in the R3 category. Earthworms and environmental risk values leaching to groundwaters are determined in the R0 category. When the exceedence values are examined; Between the values of 0.179 - 0.400 for 3 active substances (chlorantraniliprole, cycraniliprole and), two different doses of 1 active substance for bees (cyantrailiprole) 0.466 - 0.475 values, 5 active substance for soil. thiabendazole) 0.517 and 1,000. In this study, it was calculated that the active substance of flubendiamide has the highest exceedence value (1,400) in environmental indicators and the highest exceedence value in the environmental indicators was in the soil (4.517) indicator. In this study, exceedence values were obtained using formulea. It is recommended that applications be supported by field trials.
