## Abstract

The present invention relates to phytosanitary compositions with fungicidal properties that comprise a mixture of essential oils obtained from plants and agents with known fungicidal properties, such as alkali metal or ammonium bicarbonates, and compounds based on copper or the salts thereof, for use, principally, in contact-protection against fungal infections in cultivated plants and post-harvest, and also in other antifungal applications. In said compositions, the effect of the agents that have known fungicidal properties is potentiated synergistically by the aforementioned essential oils. The present invention also relates to the use of said essential oils as potentiators for agents with known fungicidal properties.

## Claims

### Claim 1

A phytosanitary composition comprising:
(A) one or more active compounds chosen from carvacrol or a combination of carvacrol and thymol; and
(B) potassium bicarbonate,
wherein:
the phytosanitary composition has antifungal activity;
the carvacrol is present in a concentration of 0.1 ppm, 0.31 ppm, or 10 ppm;
when present, the thymol is present in a concentration of at least 0.31 ppm; and
the potassium bicarbonate is present in a concentration of 30 mM.

### Claim 2 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition is a liquid.

### Claim 3 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition consists essentially of the one or more active compounds and the potassium bicarbonate.

### Claim 4 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition consists of the one or more active compounds and the potassium bicarbonate.

### Claim 5 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition comprises:
a concentration of at least 0.31 ppm of the carvacrol.

### Claim 6 (depends on 1)

The phytosanitary composition of claim 1, wherein the one or more active compounds comprises the thymol.

### Claim 7 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition comprises:
a concentration of at least 1 ppm of the thymol.

### Claim 8 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition comprises:
a concentration of at least 10 ppm of the thymol.

### Claim 9 (depends on 1)

The phytosanitary composition of claim 1, wherein the phytosanitary composition comprises:
a concentration of 0.31 ppm, 1 ppm, or 10 ppm of the thymol.

### Claim 10 (depends on 1)

A method of disinfecting harvested agricultural products, the method comprising contacting the harvested agricultural products with the phytosanitary composition of claim 1.

### Claim 11

A phytosanitary composition comprising:
(A) one or more active compounds chosen from carvacrol or a combination of carvacrol and thymol;
(B) potassium bicarbonate; and
(C) one or more fertilisers, herbicides, insecticides, plant growth regulators, or combination thereof;
wherein:
the phytosanitary composition has antifungal activity;
the carvacrol is present in a concentration of 0.1 ppm, 0.31 ppm, or 10 ppm;
when present, the thymol is present in a concentration of at least 0.31 ppm; and
the potassium bicarbonate is present in a concentration of 30 mM.
