ABSTRACT
Today we want to present information on malathion applied as technical in an ultra-low volume (ULV) spray against the boll weevil in area-wide eradication programs across the cotton belt in the United States. The eradication program is effective. This is because the use rate of technical malathion is an extremely effective contact insecticide against the boll weevil. It is the only registered insecticide applied in technical form to cotton. It was registered for use on cotton in the early 1950s and it has been used on cotton in various formulations ever since. Technical malathion is registered for use in a "Boll Weevil Attract and Kill Tube" with cottonseed oil-shellac formulation.
