Abstract:
This experiment was designed with two treatments of synthetic pesticide & biopesticide. Laboratory experiment was carried out to investigate the effect of different concentration levels of dimethoate & neem extracts (10, 50, 100) mgl-1 on germination and radical length of mung plant. Seeds after 3 days of germination & 19 days old seedlings were exposed to same concentration of dimethoate & neem extracts through foliar spray. Analysis were done using F-test to find out the effect of synthetic pesticide & biopesticide on leaf area, shoot length, chlorophyll, protein, amino acid, carbohydrate & amino acid content of mung plant. 62.5 to 72% germination takes place in control & seed treated with biopesticide but 50% in seed treated with pesticide. Radical length showed maximum increase in biopesticide treated seed as compared to synthetic pesticide treated seed. Foliar application of biopesticide significantly improved the shoot length by 10.85 cm & leaf area by 5.46 cm2 as compared to synthetic pesticide treated plant. Further increase in insecticide level had a negative impact upon biochemical characters studied. There is significant increase in protein & carbohydrate content of mung plant treated with biopesticide where as decrease in synthetic pesticide treated plant. The result also shows increase in chlorophyll & amino acid content in biopesticide treated plant but no significant difference found between the biopesticide & synthetic pesticide treated plant. The doses of biopesticide proved more efficient than doses of pesticide. Among these, Neem treated plant exhibit strong morphological and biochemical parameters to suppress pesticide treated plant.
