Residues of insect growth regulators on Queensland wool

Trends in the use of pesticides and pestiside residues on Queensland wool

“…A survey of the Queensland wool clip for IGR pesticides (cyromazine, diflubenzuron and triflumuron) has recently been completed. 11 Whilst most wool samples tested contained < 1 mg/kg of these pesticides, highest concentrations reached 120, 310 and 240 mg per kg of greasy wool, respectively. The use of IGR pesticides and the factors associated with large amounts of residues will need to be monitored, in the same way that OP and SP residues have been monitored, in order to avoid too much of these pesticides on wool and to maintain the clean and natural image of wool.…”

Surveys to assess the amount of pesticide in wool and the use of pesticides by woolgrowers in Queensland

“…Amounts of pesticides in Queensland wool and application practices used by Queensland woolgrowers have been reported for the period 1993 to 1997. [4][5][6] Over this period, a decrease in the amounts of OP and SP residues was observed. Pesticides to control infestations of lice appear to be the major contributor to the amount of residues in wool.…”
