Abstract

The persistence of triphenyltin chloride‐triphenylphosphine oxide (Ph3SnCl·Ph3PO) and diphenylbutyltin bromide (Ph2BuSnBr) in unsterilized sandy loam soil maintained in the dark at 60% of its water‐holding capacity and at 27±2°C was studied over a period of 29 days. The percentage recovery of the compounds upon extraction with acetone immediately after application to soil was 60% for Ph3SnCl·Ph3PO and 9.8% for Ph2BuSnBr. The half‐lives of the compounds were 15 days for Ph3SnCl·Ph3PO and 14.2 days for Ph2BuSnBr. After 29 days following application of the compounds in soil < 8.3 μg g−1 of Ph3SnCl·Ph3PO and < 5.1 μg g−1 of Ph2BuSnBr remained in soil compared with the starting concentration of 50 μg of each compound per gram soil. The two triorganotin compounds were evidently easily degraded and the compounds may be applied every 2–3 weeks in the field at a rate of at least 0.005–0.01 kg ha−1.
