Abstract

This invention is related to the use of a volatile antimicrobial compound against pathogens. The volatile antimicrobial compounds provided include certain oxaborole compounds, for example benzoxaboroles. Delivery systems are provided to take advantage of the volatile nature of these antimicrobial compounds. The method and use disclosed can be combined with other volatile compounds.

First claim

We claim:

1. A method of using a volatile antimicrobial compound against pathogens affecting meats, plants, or plant parts, comprising contacting the meats, plants, or plant parts with an effective amount of the volatile antimicrobial compound having a structure of formula (I) or (II):

wherein q 1 is 1;
M is hydrogen, halogen, —OCH 3 , or —CH 2 —O—CH 2 —O—CH 3 ;
M 1 is halogen, —CH 2 OH, or —OCH 3 ;
R 1 and R 2 are independently hydrogen;
R* is substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl;
and agriculturally acceptable salts thereof.

2. The method of claim 1 , wherein R* is substituted or unsubstituted heteroaryl.

3. The method of claim 1 , wherein R* is halo substituted aryl or alkoxy substituted aryl.

4. The method of claim 1 , wherein R* is substituted or unsubstituted aryl.

5. The method of claim 4 , wherein R* is fluoro substituted aryl or methoxy substituted aryl.

6. The method of claim 4 , wherein R* is fluoro substituted aryl.

7. The method of claim 4 , wherein R* is methoxy substituted aryl.

8. The method of claim 4 , wherein R* is unsubstituted aryl.

9. The method of claim 1 , wherein the compound is selected from the group consisting of

or agriculturally acceptable salts thereof.

10. The method of claim 1 , wherein the pathogen is selected from the group consisting of Acremonium spp., Albugo spp., Alternaria spp., Ascochyta spp., Aspergillus spp., Botryodiplodia spp., Botryospheria spp., Botrytis spp., Byssochlarnys 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.

11. The method of claim 1 , wherein the pathogen is selected from the group consisting of Erwinia spp., Pantoea spp., Pectobacterium spp., Pseudomonas spp., Ralstonia spp., Xanthomonas spp.; Salmonella spp., Escherichia spp., Lactobacillus spp., Leuconostoc spp., Listeria spp., Shigella spp., Staphylococcus spp., Candida spp., Debaryomyces spp., Bacillus spp., Campylobacter spp., Clavibacter spp., Clostridium spp., Cryptosporidium spp., Giardia spp., Vibrio spp., Xanthomonas spp., and Yersinia spp.

12. The method of claim 1 , wherein the method comprises a pre-harvest treatment or a post-harvest treatment.

13. The method of claim 12 , wherein the post-harvest treatment is selected from the group consisting of treatment during field packing, treatment during palletization or after palletization, in open pallets or in wrapped pallets, in tents, in-box treatments with or without liners, in sea container, truck or other container types used during transportation, and treatment during storage (Regular atmosphere or Controlled atmosphere), and/or throughout the distribution network.

14. The method of claim 1 , wherein the meats, plants, or plant parts are selected from the group consisting of fruit, vegetables, nursery, turf and ornamental crops.

15. The method of claim 1 , wherein the fruit is selected from the group consisting of banana, pineapple, citrus, grapes, watermelon, cantaloupe, muskmelon, and other melons, apple, peach, pear, cherry, kiwifruit, mango, nectarine, guava, papaya, persimmon, pomegranate, avocado, fig, citrus, and berries.

16. The method of claim 1 , wherein the contacting comprises applying the volatile antimicrobial compound by ways selected from the group consisting of spray, mist, thermal or non-thermal fogging, drench, gas treatment, and combinations thereof.

17. The method of claim 16 , wherein the gas treatment is selected from the group consisting of release from a sachet, release from a synthetic or natural film or fibrous material, release from liner or other packaging materials, release from powder, release from a gas-releasing generator, release using a compressed or non-compressed gas.
