Abstract

A pesticidal mixture comprising as active ingredient a mixture of component A and component B, wherein component A is a compound of formula (I), in which Q is i or ii wherein X, Y and Z, m and n, A, G, and R, are as defined as in claim 1 , and component B is a compound selected from the insecticides as defined in claim 1 . The present invention also relates to methods of using said mixtures for the control of plant pests.

First claim

The invention claimed is:

1. A pesticidal mixture comprising as active ingredient a mixture of component (A) and component (B), wherein component (A) is a compound of formula (I)

in which Q is
i

X, Y and Z independently of each other are C 1-4 alkyl, C 1-4 haloalkyl, C 1-4 alkoxy, C 1-4 haloalkoxy or halogen;
m and n, independently of each other, are 0, 1, 2 or 3 and m+n is 0, 1, 2 or 3;
G is hydrogen, a metal, an ammonium, a sulfonium or a latentiating group, wherein the latentiating group is selected from —C(═O)—R a and —C(═O)—O—R b , wherein R a is selected from hydrogen, C 1 -C 12 alkyl, C 2 -C 12 alkenyl, C 2 -C 12 alkynyl, C 1 -C 10 haloalkyl and R b is selected from C 1 -C 12 alkyl, C 2 -C 12 alkenyl, C 2 -C 12 alkynyl, and C 1 -C 10 haloalkyl;
R is hydrogen, C 1-4 alkyl, C 1-4 haloalkyl; and
A is C 1-4 alkyl;
or an agrochemically acceptable salt or an N-oxide thereof;
component (B) is selected from acetamiprid;
wherein the weight ratio of component (A) to component (B) is from 500:1 to 1:100.

2. A pesticidal mixture according to claim 1 , wherein in the compound of formula (I) R is selected from the group consisting of hydrogen, methyl, ethyl, iso-propyl, n-propyl, tert-butyl, sec-butyl, iso-butyl, and n-butyl.

3. A pesticidal mixture according to claim 1 , wherein in the compound of formula (I), X, Y and Z are selected, independently of each other, from the group consisting of methyl, ethyl, iso-propyl, n-propyl, methoxy, fluoro, bromo and chloro, when m+n is 1, 2 or 3.

4. A pesticidal mixture according to claim 1 , wherein in the compound of formula (I), A is methyl.

5. A pesticidal mixture according to claim 1 , wherein Q is (i), m is 1, n is 1, X is methyl, Y is in the ortho position and is methyl, Z is in the para position and is chloro, G is —(C═O)—O—CH2CH3, A is methyl and R is methyl.

6. A pesticidal mixture according to claim 1 , wherein the mixture comprises an agricultural acceptable carrier and optionally a surfactant.

7. A pesticidal mixture according to claim 1 , wherein the mixture comprises formulation adjuvants.

8. A method of controlling insects or acarines, which comprises applying to a pest, to a locus of a pest, or to a plant susceptible to attack by a pest a combination of components (A) and (B), wherein the combination of components (A) and (B) is a mixture according to claim 1 .

9. The method according to claim 8 wherein the components (A) and (B) slow down the spread of disease in a plant.

10. The method according to claim 8 for controlling insects, wherein the insects are neonicotinoid resistant.

11. A seed comprising a mixture as defined in claim 1 .

12. A pesticidal mixture according to claim 1 , wherein the weight ratio of component (A) to component (B) is from 33:1 to 1:5.
