Changes in total protein, carbohydrate, phenolic content and ninhydrine positive amino acids of susceptible (MexiPak) and resistant (Povan) varieties of wheat were studied. Application of systemic fungicides caused a significant (P<0.001) decrease in total protein and carbohydrate content compared to the control. MexiPak (susceptible) was more adversely affected than Povan (resistant). A substantial increase in total phenol was observed in the two varieties tested. Among the amino acids, proline, methionine, tyrosine and tryptophane were found in appreciable amounts.
