International Classification:

A01N 6300
A01N 4340
B01F 1700

US Classification:

504118

Abstract:

The invention provides novel mepiquat plant growth regulator compositions which have improved hygroscopicity and corrosion characteristics. The novel mepiquat plant growth regulator compositions of the invention can be readily prepared from technical mepiquat chlorid inter alia by electrochemical ion exchange processes or by quaternization of N-methylpiperidine with dimethylcarbonate as starting material.

Filed:

Oct 22, 1996

Appl. No.:

8/734907

Inventors:

David G. Hobbs - Research Triangle Park NC
Brian J. Campbell - Seattle WA
William D. Lidster - Sacramento CA

Assignee:

Abott Laboratories - Abbott Park IL

International Classification:

A01N 2510
A01N 2522

US Classification:

504116

Abstract:

The present invention relates to pesticidal compositions comprising an amount of a UV sensitive pesticide and a lignin as a UV sunscreen in an effective amount to protect the pesticide against inactivation by UV radiation for extending the persistence of the UV sensitive pesticide in the natural environment to control a pest and/or for reducing the amount of the pesticide typically needed to be a commercially effective pesticide. The present invention also relates to a method for protecting a UV sensitive pesticide against inactivation by UV radiation. The present invention further relates to a method for controlling a pest comprising exposing the pest to the pesticidal compositions of the present invention.
