- A01N: PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toiletry purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS

## Abstract

The present invention provides a method for the prevention/treatment of hark beetle and/or wood borer infestation of trees comprising treatment of the tree with a composition comprising a macroyclic lactone.

## Claims

### Claim 1

A method for the prevention/treatment of bark beetle and/or wood borerinfestation of trees comprising treatment of the tree with a composition comprising a macroyclic lactone.

### Claim 2 (depends on 1)

The method as claimed in claim 1 wherein the macrocylic lactone is a compound of formula I:
in which
R1 to R9 represent, independently of each other hydrogen or a substituent;
m is 0, 1 or 2;
n is 0, 1, 2 or 3; and
the bonds marked with A, B, C, D, E and F indicate, independently of each other, that two adjacent carbon atoms are connected by a double bond, a single bond, a single bond and an epoxide bridge of the formula
or a single bond and a methylene bridge of the formula
including, where applicable, an E/Z isomer, a mixture of E/Z isomers, and/or a tautomer thereof, in each case in free form or in salt form.

### Claim 3 (depends on 2)

The method of claim 2, wherein the macrocylic lactone is a compound of the formula (II):
wherein R1 is methyl or ethyl.

### Claim 4 (depends on 3)

The method of claim 3, wherein the macrocyclic lactone is the benzoic acid salt of formula II.

### Claim 5

The method of any one of the preceding claims wherein the compound is applied to the tree using an injection technique.
