Abstract

Fungicides, weedicides, insecticides etc. are all pesticides used for protection of plant. A fungicide is a group of pesticide that controls fungal disease by either inhibiting or killing the fungus that causes the disease. Fungicides are generally used for increasing yield of crop but they can induce biochemical changes in seedlings which may not be beneficial. Therefore the study was conducted to know the harmful effect of carbendazim which is a benziimidazole group fungicide on biochemical parameters of wheat seedlings. The biochemical parameters studied were protein, carbohydrate, total chlorophyll, chlorophyll a, chlorophyll b and alkaline protease activity. Five different concentration of fungicide were used viz. 500, 1000, 1500, 2000 and 2500 mg/l. Protein, carbohydrate, total chlorophyll, chlorophyll a, and chlorophyll b were found to decrease with increase in concentration of fungicide. However alkaline protease activity was increased with increase in concentration of fungicide. Maximum decrease in protein (– 62.49%), carbohydrate (– 62.5%), total chlorophyll (-57.44%), chlorophyll a (-47.89%) and chlorophyll b (-63.44%) and maximum increase in alkaline protease activity (152%) was obtained at highest studied concentration of fungicide i.e. 2500 mg/l. From the present study it was concluded that presence of fungicide exert harmful effect on the biochemical parameters of wheat seedlings.
