COMPOUNDS FOR USE IN THE TREATMENT OF PLANTS

摘要

The invention relates to use of a compound in a treatment of a plant to promote plant growth wherein the compound is a salt comprising an anion of formula (1): or a conjugate acid thereof, wherein: R1, R2, R3, R4 and R5 are each independently selected from H, halogen, optionally substituted C1-C10 alkyl, optionally substituted C2-C10 alkenyl, optionally substituted C2- C10 alkynyl, optionally substituted C3-C10 cycloalkyl, optionally substituted C3-C10 cycloalkenyl, optionally substituted C3-Ci0 cycloalkynyl, hydroxy, optionally substituted C1 -C10 alkoxy, amino, mono-(C1-C10 alkyl)amino and di-(C1-C10 alkyl)amino groups; and Y is a nitrogen containing heterocyclyl group having from 3 to 14 ring atoms, a nitrogen containing heteroaryl group having from 3 to 14 ring atoms, an optionally substituted mono-(C1-C10 alkyl)amino group, an optionally substituted di-(C1-C10 alkyl)amino group or an optionally substituted tri-(C1-C10 alkyl)amino group. The compounds can be used to prevent or reduce stomatal closure or to cause stomatal opening in a plant. The invention further provides compounds for use in a herbicidal treatment of a plant. New compounds and a method for their manufacture are also described.
