Studies on Host Plant Resistance to Evaluate the Tolerance/Susceptibility Against Cotton Pests

Mushtaque Ali Leghari , Ali Muhammad Kalroo and Allah Bux Leghari

Abstract: Studies were carried out to determine natural resistance of cotton varieties against insect pests. Population of thrips reached above threshold levels from 1^st week to 3^rd week of July in all the strains/varieties (CRIS-120, CRIS-126, CRIS-133, CRIS-134, CRIS-9 and NIAB-78) and needs to be sprayed to protect the crop from economic loss. CRIS-134 showed more tolerance against bollworm damage followed by CRIS-133. Maximum seed cotton yield was obtained from CRIS-120, followed by NIAB-78 and CRIS-126 respectively. Regular pest scouting should be carried out in the field and when pest populations reach at threshold levels, the crop should be sprayed with appropriate pesticides accordingly.
