Impact of Some Biocides on Chlorophyll and Enzymatic Activities of Rice Plants
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 2
Abstract
Agricultural productivity has increased substantially in the last half century due in part to the introduction and expanded use of agricultural chemicals. Pesticides continue to be a significant and growing component of modern rice technology. The relative importance of pesticides has increased despite the availability of alternatives to exclusive chemical pest control such as varietal resistance and integrated pest management IPM . The evaluation of toxicological impact of pesticides in the tropical paddy has been evaluated through estimation of chlorophyll content and enzymatic activities peroxidase and polyphenol oxidase . The seedlings are the crucial stage of the plant, so, the experimental study evaluated 14 days old seedling's chlorophyll content and enzymatic activities influenced by different biocides neem oil, carbosulfan and Oxadiargyl . The experimental results found that all concentrations of 0.5, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0 ml l neem oil, carbosulfan and oxadiargyl decreased the percentage of chlorophyll content and enzymatic activities peroxidase and polyphenol oxidase of 14 days old seedlings. Among three biocides, neem oil was found less toxic towards the test cultivar followed by carbosulfan and oxadiargyl. The experimental studies concluded that neem oil is good for pest management. Farmer's should be well trained on proper application and implementation of integrated pest management strategies on rice field by which it restore sustainability of ecosystem and increased productivity.
