Chickweed bioherbicides
View Patent ↗The present invention relates to the use of a strain of Burkholderia andropogonis for controlling the growth of a weed belonging to the order Caryophyllales. The present invention also provides a method for suppressing weed growth, comprising applying a strain of Burkholderia andropogonis to a weed belonging to the order Caryophyllales. Also provided is a biocontrol composition for controlling the growth of a weed belonging to the order Caryophyllales, the composition comprising a strain of Burkholderia andropogonis , and a suitable medium.
1. A method for suppressing weed growth, comprising applying a composition comprising Burkholderia andropogonis (Smith 1911) Gillis et al. 1995, comb. nov., deposited under ATCC Accession No. PTA-4234 and a suitable medium, to a weed belonging to the order Caryophyllales.
2. The method of claim 1 , wherein the weed is a member of the family Caryophyllaceae.
3. The method of claim 1 , wherein the weed is a member of the subfamily Alsinoideae.
4. The method of claim 1 , wherein the weed is a member of the genus Stellaria.
5. A method of suppressing weeds during crop growth comprising:
a) adding an effective amount of a biocontrol composition comprising Burkholderia andropogonis (Smith 1911) Gillis et al. 1995, comb. nov., deposited under ATCC Accession No. PTA-4234 and a suitable medium, to an area of plants, and
b) growing said plants.
6. A biocontrol composition comprising isolated Burkholderia andropogonis (Smith 1911) Gillis et al. 1995, comb. nov., deposited under ATCC Accession No. PTA-4234, and a suitable medium.
7. An isolated bacterial strain having the ATCC designation PTA-4234.
8. A method for suppressing weed growth, comprising applying Burkholderia andropogonis (Smith 1911) Gillis et al. 1995, comb. nov., deposited under ATCC Accession No. PTA-4234 to a weed belonging to the order Caryophyllales.
9. The method of claim 8 , wherein the weed is a member of the family Caryophyllaceae.
10. The method of claim 8 , wherein the weed is a member of the subfamily Alsinoideae.
11. The method of claim 8 , wherein the weed is a member of the genus Stellaria.
12. The method of claim 1 , wherein the composition further comprises a surfactant.
13. The method of claim 5 , wherein the composition further comprises a surfactant.
14. The biocontrol composition of claim 6 , wherein the composition further comprises a surfactant.
15. The method of claim 12 , wherein said surfactant is an organosilicone-based surfactant.
16. The method of claim 13 , wherein said surfactant is an organosilicone-based surfactant.
17. The biocontrol composition of claim 14 , wherein said surfactant is an organosilicone-based surfactant.
