Tank Mixes: Consequences of Using Insecticide and Disinfectant Mixtures to Reduce Flies and Bacteria

The use of disinfectants and insecticides to control pathogens and the insects that may harbor avian pathogens has become routine for on-farm biosecurity programs. It is commonplace for producers to wash, disinfect, and apply insecticides to poultry houses between flock cycles. Occasionally, the urgency to repopulate the houses limits the time producers have to adequately perform preflock sanitization of the premise. The use of tank mixes (i.e., combining insecticides and disinfectants in a single application) saves time and labor. This study examined the consequences of using insecticide and disinfectant used separately or as a mixture for the control of the bacterium Salmonella Typhimurium and the house fly (Musca domestica). Aldehyde + formalin- and aldehyde + glutaraldehyde/quaternary ammonium (DC&R and Synergize)-based disinfectants were effective against Salmonella Typhimurium at the label rate. Disinfectant classes quaternary ammonium (Tryad), iodine (Dyne-O-Might), and peroxymonosulfate (Virkon S) were ineffective at label rates or in mixtures with insecticides. House fly mortality was 100% for tetrachlorvinphos/vapona (Ravap), Spinosad (Elector), and cyfluthrin (Tempo) and above 92% for permethrin (Martin’s Permethrin) and tetrachlorvinphos (Rabon) insecticides. Permethrin efficacy was compromised by the addition of disinfectants in all cases except the glutaraldehyde/quaternary ammonium blend. Elector efficacy was reduced when blended with iodine or peroxymonosulfate disinfectant classes. Tempo insecticidal activity was compromised when mixed with Tryad and Virkon S. Ravap and Rabon efficacy against house flies was unchanged in mixture.
