Abstract

Experiments were conducted in 1993 and 1994 to determine persistence of pyrithiobac as determined by bioavailability following different application times in a silty clay. Pyrithiobac was applied at PPI, PRE, pinhead square (PHS), and first bloom (FB) application timings. Greenhouse studies were also conducted in 1993 and 1994 to determine pyrithiobac persistence under controlled conditions on a sandy loam soil. Slope comparison indicated no difference in degradation patterns in the field for any application timing of pyrithiobac within years; thus, application timings were combined for 1993 and 1994. Slope comparison also indicated no difference in slope between 1993 and 1994; thus, years were combined to determine pyrithiobac persistence. The initial concentration was 30 ηg g−1. The half-life of pyrithiobac was 62 d in the field. Analysis of covariance indicated no difference in slope for the 1993 and 1994 greenhouse studies, and years were combined to determine the half-life. The initial concentration was 43 η g−1. The half-life was 43 d in the greenhouse study.
