Studies were carried out under field conditions on the effect of micronutrients on plant growth and insect infestation of cotton crop. Cotton (NIAB-78) was sown in a randomized block design with four replications on May 10, 2000. Two micronutrients Nitroplus and Golden harvest were applied on August 15, 2000 and two subsequent applications were made at 15 days intervals. The results revealed that there was significant (P0.05) effect of application of micronutrients on plant height, number of fruiting bodies and volume of bolls in comparison to control. There was no significant effect of application of micronutrient on multiplication of jassid and whitefly. Significantly lower population of thrips and percent infestation of bollworms was recorded on micronutrient applied cotton compared with control plots. Application of micronutrients also did not have any significant effect on the maturity of cotton.
