Field studies were conducted at the Southeast Research and Extension Center-Rohwer Division, near Rohwer. AR in 1998 to evaluate in-furrow insecticide treatments for thrips control in conventional and ultr narrow row cotton.

In general, good thrips control and damage protection was observed from insecticide treatments in both cotton systems. Although, differences were seen in thrips numbers, damage and phytotoxicity ratings they did not translate to yield. This effect may not have occurred due to the plants ability to compensate when grown with newer varieties and/or under conditions more conducive for adequate growth.

These studies demonstrate that seedling cotton grown under warm, dry conditions is tolerant of low numbers of thrips soon after emergence. Even when populations build later on, yield losses do not always occur.
