Abstract

The present disclosure relates to methods for using benzoxaborole compounds in combination with preservative gases, such as carbon dioxide or sulfur dioxide, as an antimicrobial that synergistically controls pathogens of agricultural crops.

First claim

What is claimed is:

1. A method of treating plants with an antimicrobial treatment comprising:
placing one or more plants or plant parts in a chamber,
sealing the chamber,
adding a benzoxaborole compound to the chamber,
adding CO 2 to the chamber,
wherein the benzoxaborole compound and the CO 2 combine to form the antimicrobial treatment,
administering the antimicrobial treatment to the one or more plants or plant parts in the sealed chamber,
unsealing the chamber,
wherein 1-methylcyclopropene is not combined with the benzoxaborole,
wherein the combination of the benzoxaborole and the CO 2 provide synergistic inhibition of plant pathogens on the one or more treated plants or plant parts,
wherein the benzoxaborole has the structure,

or analogs or derivatives thereof,
wherein the CO 2 concentration is about 12%, and
wherein the benzoxaborole is applied from about .004mg/L to about 0.15mg/L.

2. The method of claim 1 , wherein the one or more plants or plant parts is a soft fruit.

3. The method of claim 2 , wherein the soft fruit is selected from the group consisting of a strawberry, a raspberry, a blackberry, and a grape.

4. The method of claim 1 , wherein the benzoxaborole compound is in the form of a liquid, a gas, a fog, or a solid.

5. The method of claim 4 , wherein the solid benzoxaborole compound is a powder.

6. The method of claim 1 , wherein the antimicrobial treatment is in the form of a spray, a mist, a gel, a thermal fog, a non-thermal fog, a dip, a drench, a vapor, a gas, or sublimation.

7. The method of claim 1 , wherein the antimicrobial treatment further comprises a treatment carrier.

8. The method of claim 1 , wherein the antimicrobial treatment is effective against fungal pathogens.

9. The method of claim 8 , wherein the fungal pathogens are selected from the group consisting of Acremonium spp., Albugo spp., Alternaria spp., Ascochyta spp., Aspergillus spp., Botryodiplodia spp., Botryospheria spp., Botrytis spp., Byssochlamys spp., Candida spp., Cephalosporium spp., Ceratocystis spp., Cercospora spp., Chalara spp., Cladosporium spp., Colletotrichum spp., Cryptosporiopsis spp., Cylindrocarpon spp., Debaryomyces spp., Diaporthe spp., Didymella spp., Diplodia spp., Dothiorella spp., Elsinoe spp., Fusarium spp., Geotrichum spp., Gloeosporium spp., Glomerella spp., Helminthosporium spp., Khuskia spp., Lasiodiplodia spp., Macrophoma spp., Macrophomina spp., Microdochium spp., Monilinia spp., Monilochaethes spp., Mucor spp., Mycocentrospora spp., Mycosphaerella spp., Nectria spp., Neofabraea spp., Nigrospora spp., Penicillium spp., Peronophythora spp., Peronospora spp., Pestalotiopsis spp., Pezicula spp., Phacidiopycnis spp., Phoma spp., Phomopsis spp., Phyllosticta spp., Phytophthora spp., Polyscytalum spp., Pseudocercospora spp., Pyricularia spp., Pythium spp., Rhizoctonia spp., Rhizopus spp., Sclerotium spp., Sclerotinia spp., Septoria spp., Sphaceloma spp., Sphaeropsis spp., Stemphyllium spp., Stilbella spp., Thielaviopsis spp., Thyronectria spp., Trachysphaera spp., Uromyces spp., Ustilago spp., Venturia spp., and Verticillium spp., and bacterial pathogens, such as Bacillus spp., Campylobacter spp., Clavibacter spp., Clostridium spp., Erwinia spp., Escherichia spp., Lactobacillus spp., Leuconostoc spp., Listeria spp., Pantoea spp., Pectobacterium spp., Pseudomonas spp., Ralstonia spp., Salmonella spp., Shigella spp., Staphylococcus spp., Vibrio spp., Xanthomonas spp., and Yersinia spp.

10. The method of claim 9 , wherein the fungal pathogens are selected from the group consisting of Botrytis cinerea, Mucor piriformis, Fusarium sambucinum, Aspergillus brasiliensis , and Peniciliium expansum.

11. The method of claim 1 , wherein the method results in synergistic inhibition having a Colby calculation of 100.4 to 502.5.

12. The method of claim 1 , wherein the plant pathogen is a fungal plant pathogen.

13. The method of claim 12 , wherein the benzoxaborole has the structure of

14. The method of claim 12 , wherein the benzoxaborole has the structure of
