Disclosure is provided for methods of preventing, removing or inhibiting microbial biofilm formation or microbial infection in a plant or plant part thereof, including applying thereto a treatment effective amount of an active compound as described herein, or an agriculturally acceptable salt thereo
Disclosure is provided for methods of preventing, removing or inhibiting microbial biofilm formation or microbial infection in a plant or plant part thereof, including applying thereto a treatment effective amount of an active compound as described herein, or an agriculturally acceptable salt thereof. Methods of enhancing a microbicide (e.g., including a copper, antibiotic, bacteriophage, etc.) and/or plant defense activator are also provided, including applying an active compound as described herein. Compositions comprising an active compound as described herein in an agriculturally acceptable carrier are also provided, and in some embodiments the compositions further include a microbicide (e.g., including copper, antibiotic, bacteriophage, etc.) and/or plant defense activator.

1. An agricultural composition comprising: (a) an agriculturally acceptable carrier; and(b) an antimicrobial or biofilm removing or inhibiting compound of Formula (II)(a): wherein: R1a and R1b are each H;R2, R3 and R5 are each independently H or alkyl;each occurrence of Rx, Ry, Ru and Rv is present
1. An agricultural composition comprising: (a) an agriculturally acceptable carrier; and(b) an antimicrobial or biofilm removing or inhibiting compound of Formula (II)(a): wherein: R1a and R1b are each H;R2, R3 and R5 are each independently H or alkyl;each occurrence of Rx, Ry, Ru and Rv is present or absent (depending upon chain saturation), and are each independently H or alkyl;R6 is independently selected from the group consisting of: H, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, nitro, carboxy, amino acid sidechain, amino acid and peptide,wherein R6 is optionally substituted with one, two, three or four substituents independently selected from the group consisting of: halo, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, oxo, oxy, nitro, carbonyl, carboxy, amino acid sidechain, amino acid and peptide;n=0 to 10; andm=0 to 20;or an agriculturally acceptable salt thereof,wherein said composition further comprises a microbicide, a bacteriophage or a plant defense activator. 2. The composition of claim 1, wherein said composition comprises a microbicide. 3. The composition of claim 2, wherein said microbicide comprises copper. 4. The composition of claim 1, further comprising an antibiotic. 5. The composition of claim 1, wherein said composition comprises a bacteriophage. 6. The composition of claim 1, wherein said composition comprises a plant defense activator. 7. The composition of claim 1, wherein said carrier is an aqueous carrier or a solid particulate carrier. 8. The composition of claim 1, wherein said compound of Formula (II)(a) is a compound of Formula (II)(a)(5)(D): or an agriculturally acceptable salt thereof. 9. A method of removing or inhibiting microbial biofilm formation or microbial infection in a plant or plant part thereof, comprising applying to said plant or plant part a treatment effective amount of a compound of Formula (II)(a): wherein: R1a and R1b are each H;R2, R3 and R5 are each independently H or alkyl;each occurrence of Rx, Ry, Ru and Rv is present or absent (depending upon chain saturation), and are each independently H or alkyl;R6 is independently selected from the group consisting of: H, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, nitro, carboxy, amino acid sidechain, amino acid and peptide,wherein R6 is optionally substituted with one, two, three or four substituents independently selected from the group consisting of: halo, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, oxo, oxy, nitro, carbonyl, carboxy, amino acid sidechain, amino acid and peptide;n=0 to 10; andm=0 to 20;or an agriculturally acceptable salt thereof. 10. The method of claim 9, wherein said plant is a fruit crop plant or a vegetable crop plant. 11. The method of claim 9, wherein said microbial biofilm formation or microbial infection is caused by a fungi. 12. The method of claim 9, wherein said compound is applied to said plant in an amount effective to treat or control a fungal disease selected from the group consisting of rots, leaf molds, blights, wilts, damping-off, spot, root rot, stem rot, mildew, brown spot, gummosis, melanose, post-bloom fruit drop, scab, alternaria, canker, flyspeck, fruit blotch, dieback, downy mildews, ear rots, anthracnose bunts, smut, rust, eyespot and pecky rice. 13. The method of claim 9, wherein said compound of Formula (II)(a) is a compound of Formula (II)(a)(5)(D): or an agriculturally acceptable salt thereof. 14. A method of enhancing the effects of a microbicide comprising applying a compound of Formula (II)(a): wherein: R1a and R1b are each H;R2, R3 and R5 are each independently H or alkyl;each occurrence of Rx, Ry, Ru and Rv is present or absent (depending upon chain saturation), and are each independently H or alkyl;R6 is independently selected from the group consisting of: H, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, nitro, carboxy, amino acid sidechain, amino acid and peptide,wherein R6 is optionally substituted with one, two, three or four substituents independently selected from the group consisting of: halo, hydroxy, acyl, alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclo, aryl, heteroaryl, alkoxy, amino, amide, thiol, sulfone, sulfoxide, oxo, oxy, nitro, carbonyl, carboxy, amino acid sidechain, amino acid and peptide;n=0 to 10; andm=0 to 20;or an agriculturally acceptable salt thereof, in combination with said microbicide. 15.
