Abstract

The invention is in the field of the crop protection products which can be employed against harmful plants in tolerant crops of soybeans and which comprise, as herbicidally active substances, a combination of two or more herbicides.

First claim

The invention claimed is:

1. A method for controlling harmful plants in soybean crop comprising applying as the sole herbically active components,
(A) an effective amount of active substance with HPPD inhibiting activity
(A7) N,O-chelator, according to formula (I)

wherein
X is Cl;
A is C—Y, wherein
Y is SMe;
Z is CF 3 ;
W is hydrogen;
Q N is

wherein
B is nitrogen;
R is Me,
and
(B) an effective amount of the active substance metribuzine (B1)

wherein the weight ratio of (A) to (B) is 1:1 to 1:10, wherein (A) and (B) are used in amounts to provide synergistic results
to soybean crops that are from a soybean culture that is tolerant against said (A) and (B), and wherein (A) and (B) are applied together.

2. A method according to claim 1 , wherein the soybean culture comprises a heterologous gene that confers HPPD inhibitor tolerance.

3. A method according to claim 2 , wherein the HPPD tolerance of the soybean cultures is conferred by the hppdPF W336 gene.

4. A method according to claim 2 , wherein the HPPD tolerance of the soybean cultures is conferred by the avhppd-03 gene.

5. A method according to claim 1 , wherein the soybean culture or parts or seeds thereof comprise the SYHT0H2 event.

6. A method according to claim 1 , wherein the soybean culture or parts or seeds thereof comprise the EE-GM3 event.

7. Method for controlling one or more harmful plants in one or more soybean cultures comprising jointly applying, pre-emergence, post-emergence or pre- and post-emergence to the plants, parts of the plants, seeds of the plants or the area under cultivation as sole herbicidally active components an effective amount of (B) metribuzine and an effective amount of (A) active substance with HPPD inhibiting activity
(A7) N,O-chelator, according to formula (I)

wherein
X is Cl;
A is C—Y, wherein
Y is SMe;
Z is CF 3 ;
W is hydrogen;
Q N is

wherein
B is nitrogen;
R is Me
wherein the weight ratio of (A) to (B) is 1:1 to 1:10, and wherein (A) and (B) are used in amounts to provide synergistic results.

8. Method according to claim 7 wherein the soybean cultures are tolerant against the active substances (A) and (B) applied thereto.

9. A composition for controlling harmful plants in soybean crop comprising as the sole herbically active components
(A) an effective amount of active substance with HPPD inhibiting activity
(A7) N,O-chelator, according to formula (I)

wherein
X is Cl;
A is C—Y, wherein
Y is SMe;
Z is CF 3 ;
W is hydrogen;
Q N is

wherein
B is nitrogen;
R is Me,
and
(B) an effective amount of the active substance metribuzine (B1)

wherein the weight ratio of (A) to (B) is 1:1 to 1:10 and wherein (A) and (B) are present in amounts to provide synergistic results.
