LOS ANGELES (AP) - Bill Nye wants his ex-fiancee out of his life and it's not just because of some bad chemistry. Nye, who hosted the educational PBS series ''Bill Nye, the Science Guy,'' is seeking a permanent restraining order against Blair Tindall, alleging she tried to poison his vegetable garden, according to court records.

He said Tindall came to his Studio City home late Sept. 3 dressed in black and carrying ''two plastic bottles filled with some sort of solvent,'' according to court papers filed last week in Superior Court.

The bottles ''may have been emptied on my garden from which I get food produce,'' he said in the filing. Nye is seeking to keep Tindall away from his home and from contacting him.

Nye, 51, identified Tindall as his ex-fiancee, even though the two announced in February 2006 that they were married by the Rev. Rick Warren, pastor and author of ''The Purpose-Driven Life.''

An after-hour call to Tindall's attorney was not immediately returned Wednesday.

Tindall, author of ''Mozart in the Jungle'' and a former concert oboist, admitted in a declaration that she emptied two bottles of weed killer in the garden.

In court papers posted on the Web site The Smoking Gun, Tindall said that after marrying Nye, the two bought the Studio City home for $1 million. But when they found out their marriage license was ''invalid,'' Nye ''ordered me not to move into our home'' and the relationship ended.

Distress over the ''faux marriage'' and a series of financial and personal problems led to ''a foolish, sophomoric act of poor judgment that was only intended to harm flowers, and certainly not people,'' she said.

Tindall said she has sought counseling and contends she is not a threat to Nye.

A hearing was scheduled Dec. 20 in the case.
