Effects of pesticides on maize crop using experimental animals

Abstract In the present era the production and use of pesticides has been increased enormously and it has become the need to carry out such an assessment for the evaluation of pesticides effects on animals and mankind. For that, experiment has been performed to check the biosafety issue of pesticides by experimenting them on animals and also their toxicity has been analyzed on soil and plants. For this, maize crop was selected in the confined area. Pesticide used was Talstar that belongs to a pyrethroid group, and its active ingredient is bifenthrin. Plants were sprayed with this chemical and their toxicity was then checked on the animals. For such purpose four groups of chicken and two groups of rats were selected. Groups of chicken were divided as control, normal maize, high dose pesticide, and low dose pesticide whereas rats were divided as control and experimental group. They were subjected to the feeding trial of pesticide exposed feed for 45 days. Their weights were examined, and the high dose group showed significant effects. Biochemical analysis showed variations in the group belonged to high dose pesticide group. Immense increase in the number of platelets was observed in Wister rats. Morphological and histological study showed no prominent effects. Variations were seen in the negligible factors like weight and blood but only in the groups that were subjected to the high dose of pesticide. No microbial activity was disrupted. Plant growth was satisfactory. So, it is concluded that the effects of pesticides are dependent on time and duration. Hence, pesticides have both negative and positive effects in the welfare of human well-being.
