Abstract

The current invention concerns a method for the anti-sprouting treatment of tubers, especially potatoes, by applying a composition comprising limonene and a composition comprising CIPC, preferably via fogging. The invention also concerns the use of limonene as replacement of CIPC in the anti-sprouting treatment of tubers. The invention provides limonene compositions suitable for application by fogging. Furthermore, the invention concerns tubers obtainable by any of these methods.

Claims

1. Method for an anti-sprouting treatment of tubers comprising the following steps:

applying 3-chlorophenylisopropylcarbamate (CIPC) and limonene to said tubers

in a total amount of CIPC and limonene effective to at least partially suppress sprouting of said tubers and to remove sprouts that have formed on said tubers compared to untreated tubers, wherein the ratio limonene weight over CIPC weight is higher than 4.

2. Method according to claim 1, wherein CIPC is applied by hot fogging at a temperature higher than 50°

C.

3. Method according to claim 1, wherein, limonene is applied by fogging.

4. Method according to claim 1, wherein the first time the method is applied to said tubers, the ratio of the mass of limonene over the mass of CIPC is between 2 and 50.

5. Method according to claim 4, characterised in that, from the second time onward the method is applied on tubers the ratio of the mass of limonene over the mass of CIPC is between 4 and 30.

6. Method according to claim 1, wherein limonene is applied in the form of an essential oil.

7. Method according to claim 6, wherein the essential oil is orange oil.

8. Method according to claim 1, wherein said tuber is a potato.

9. Method according to claim 1, wherein limonene is applied after CIPC or CIPC is applied after limonene.

10. Method according to claim 1, wherein limonene is applied in the form of a composition comprising one or more surfactants.

11. Method according to claim 1, wherein a second treatment is carried out between 1 day and 30 days after the first treatment.

12. (canceled)

13. Composition suitable for an anti-sprouting treatment of tubers, wherein the composition is in the form of an emulsifiable concentrate (EC), comprising 550 to 750 g/l limonene and one or more emulsion stabilizing surfactants.

14. Composition according to claim 13, comprising less than 10 wt % solvent.

15. Composition according to claim 14, comprising less than 5 wt % water.

16. Composition according to claim 13, comprising 5 to 40 wt % of the one or more emulsion stabilizing surfactants.
