Bharati Bhusana Rath and Upendra Prasad Tripathy*
The main aim of this research work is to assess the effect of natural and synthetic insecticide on DNA content of Brassica Campestris (mustard). For the experimental study, two biocides, Neem oil and Carbosulfan 25% E.C. (Marshal) were taken. Neem oil is a natural bio-pesticide whereas Carbosulfan 25% E.C (Marshal) is synthetic one. The treatment of doses i.e., 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0 mg/lit.is taken on 7, 14, 21, 28, 35 days growing plants. The plant growth rate with its DNA contents of leaves as well as roots were identified. It is observed the natural insecticides (Neem oil) has a little effect on the DNA modification in leaves as well as roots as compared with the synthetic insecticides. Again, Pollution of environment by using synthetic insecticide is one of the major problems now-a-days.
Keywords: Brassica campestris, Neem oil, Carbosulfan 25% E.C. (Marshal).
