Different biochemical constituents like phenols,sug~,tannins, chlorophyll, proteins
and nutrient composition of N,P,K, Ca and Mg in leaf were estimated in fifteen chilli cultures,
representing resistant, susceptible and highly susceptible groups to mite infestation. The
different biochemical constituents and nutrients in leaf were correlated with mite incidence.
Among the biochemical parameters studied tannins, phenols, potassium, calcium, magnesium
and chlorophyll were found to have negative correlation with mite incidence. Total
sugars, protein content and nitrogen content exhibited positive association with mite
incidence. Phosphorous content in leaf did not exhibit any relationship with mite incidence.
