Effects of some fungucides and insecticides on the Vicia faba L. and Capsicum annuum L. root tip mitosis

In this research effect of some pesticides on plants were observed. One of the most common insecticide Confidor SC 350 in two different doses (0,1 g/L ve 0,05 g/L) and one of the most common fungucides Antracol in two different doses (1,25 g/L ve 0,625 g/L) were sprayed as a foliar on Vicia faba L. (broad bean) and Capsicum annuum L. (pepper) seedlings. Genetically effects of these pesticides on plants were analyzed by the meaning of chromosomal aberations in root tip mitosis. Most common effects of pesticides on the plants, stimulation or inhibition plant growth, changing the genetical configurations and changing the plant defense enzymes. In this research changing on the chromosomal abnormalities were observed. In this research, Vicia faba L. (broad bean) and Capsicum annuum L. (pepper) seedlings sprayed by insecticide Confidor SC 350 and fungucides Antracol. When we compared with the control plants, the effects of these pesticides on root tip cells (mitosis) depending on different concentrations were observed. Different kind of chromosomal anomalies like pole shifting, bridge, deorientation in chromosomes, stickness and fragmentation were observed. Depending on increasing doses of pesticides this kind of chromosomal abnormalities observed most frequently. At the end of this research, we realized that fungicides and insecticides which under the group of other pesticides are all harmful on plants. Because of that for protecting nature and environment preventing the pollution on the agricultural fields more ecological technics and biocontrol agents have to be use by farmers and researchers. Our results showed paralelity with other scientific researches. Key Words: Vicia faba L., Capsicum annuum L., Pesticides, Mitosis.
