Abstract

Compositions and methods for controlling nematodes are described herein, e.g., nematodes that infest plants or animals. The compounds include oxazoles, oxadiazoles and thiadiazoles.

First claim

What is claimed is:

1. A method for control of plant parasitic nematodes, the method comprising administering to a plant, a seed or soil a composition comprising an effective amount of a compound of Formula III or a salt thereof,

wherein,
A is phenyl or pyrazyl, each of which can be optionally independently substituted with one or more substituents selected from the group consisting of halogen, CF 3 , CH 3 , OCF 3 , OCH 3 , CN and C(H)O; and
C is thienyl, furanyl, oxazolyl, or isoxazolyl, each of which can be optionally independently substituted with one or more substituents selected from the group consisting of fluorine, chlorine, CH 3 and OCF 3.

2. The method of claim 1 wherein A is phenyl.

3. The method of claim 1 wherein C is thienyl.

4. The method of claim 1 wherein C is furanyl.

5. The method of claim 1 wherein the composition comprises a compound of Formula IIIa or a salt thereof,

wherein,
R 1 and R 5 are independently selected from the group consisting of hydrogen, CH 3 , F, Cl, Br, CF 3 , and OCF 3 ;
R 2 and R 4 are independently selected from the group consisting of hydrogen, F, Cl, Br, and CF 3 ;
R 3 is selected from the group consisting of hydrogen, CH 3 , CF 3 , F, Cl, Br, OCF 3 , OCH 3 , CN, and C(H)O;
R 7 and R 8 are independently selected the group consisting of from hydrogen and fluorine;
R 9 is selected from the group consisting of hydrogen, F, Cl, CH 3 , and OCF 3 ; and
E is O or S.

6. The method of claim 5 wherein E is S.

7. The method of claim 5 wherein E is O.

8. The method of claim 1 wherein the composition comprises a compound of Formula IIIb or a salt thereof,

wherein,
R 1 and R 5 are independently selected from the group consisting of hydrogen, CH 3 , F, Cl, Br, CF 3 , and OCF 3 ;
R 2 and R 4 are independently selected from the group consisting of hydrogen, F, Cl, Br, and CF 3 ;
R 3 is selected from the group consisting of hydrogen, CH 3 , CF 3 , F, Cl, Br, OCF 3 , OCH 3 , CN, and C(H)O;
R 8 is selected from the group consisting of hydrogen and fluorine;
R 6 and R 9 are independently selected from the group consisting of hydrogen, F, Cl, CH 3 , and OCF 3 ; and
E is O or S.

9. The method of claim 8 wherein E is S.

10. The method of claim 8 wherein E is O.

11. The method of claim 1 wherein the composition comprises 2-(4-chlorophenyl)-5-(thiophen-2-yl)-1,3,4-oxadiazole.

12. The method of claim 1 wherein the composition comprises a surfactant.

13. The method of claim 1 wherein the composition comprises a co-solvent.

14. The method of claim 1 wherein the composition further comprises one or more of an insecticide, a fungicide, an herbicide, or another pesticide.

15. The method of claim 14 wherein the insecticide, fungicide, herbicide or the pesticide is selected from the group consisting of avermectin, ivermectin, milbemycin, imidacloprid, aldicarb, oxamyl, fenamiphos, fosthiazate, metam sodium, etridiazole, penta-chloro-nitrobenzene (PCNB), flutolanil, metalaxyl, mefenoxam, fosetyl-al, silthiofam, fludioxonil, myclobutanil, azoxystrobin, chlorothalonil, propiconazole, tebuconazole, pyraclostrobin, trifloxysulfuron, glyphosate, and halosulfuron.

16. The method of claim 1 wherein the plant parasitic nemoatode is selected from the group consisting of: M incognita, H. glycines, B. longicaudatus, H. contortus, A. suum , and B. malayi , or wherein the plant parasitic nematode is a nematode of one of the following genera: Pratylenchus , Heterodera, Globodera, Meloidogyne, Rotylenchulus, Hoplolaimus, Belonolaimus, Longidorus, Paratrichodorus, Ditylenchus, Xiphinema, Helicotylenchus, Radopholus, Hirschmanniella, Tylenchorhynchus , and Trichodorus.

17. The method of claim 1 wherein the composition is applied to a seed.
