The important part of regular human diet is vegetable, which supply minerals and nutrients for maintenance of health. India is first rank producer of guar comprise 83% of total world production but these are affected by diseases like leaf spots, leaf blotch and insect pest such as serpentine leaf miners, hairy caterpillars and jassids. The major biotic constraint in vegetable production is pest problem. Application of pesticides has now become a common practice in modern agriculture. Chemicalization of agriculture rescues the crop from pest and diseases but when applied in excessive dose affects on plant health and metabolism. The various stresses alter the plant metabolism including pesticidal stress. The ureide content is reported in this study under pesticidal stress of Hexaconazole and Triazophos in leguminous vegetables guar (Cyamopsis tetragonoloba (L.) Taub.) after seed treatment and foliar sprays to ensure the nitrogen fixation and metabolism. Changes in the correlation between nitrogen fixation and ureide levels accelerate disturbance in the nitrogen metabolism and nitrogen products in plant. The concentrations of both pesticides for this experiment were 0.05, 0.1, 0.15, 0.2 and 0.3%. The seeds were soaked in these concentrations of pesticides for 12 h. After 12 h seed soaking period, the treated seeds were thoroughly washed with distilled water and sown in earthen pot containing garden soil and manure. The first foliar spray of Hexaconazole and Triazophos were applied with respective concentrations on 10th day while second foliar spray was on 25th day of plant growth. Analysis of ureide was carried out on the 15th and 30th day of growth that is 5 days after each spray. The uriede content in guar was remarkable increased after seed treatment followed by first foliar spray of 0.10, 0.15 and 0.20% hexaconazole however decreased it with dose concentrations of second foliar spray. The ureide content was decreased after both the foliar sprays of Triazophos.
