Abstract

The subject matter of the invention is the use, by burial in the soil, of a composition based on pyrethrum, with the exception of tefluthrin and of bifenthrin, and a method of controlling soil insects using said pyrethrum-based composition.

Claims

1. A method of controlling soil insects comprising ploughing into the soil a composition comprising at least pyrethrum, with the exception of tefluthrin and bifenthrin, in the form of granules or microgranules, preferably in the form of microgranules.

2. The method according to claim 1 for protection of a furrow crop against soil insects comprising the following steps:

a) making a furrow in the soil;

b) placing seed of the furrow crop on the earth at the bottom of the seed furrow formed by the furrow,

c) then spreading said composition over the full width of the seed furrow in which the seed was placed; and

d) closing the furrow with the earth prepared in step c).

3. The method according to claim 1, for protection of a ridge crop against soil insects, comprising the following steps:

a) placing seed of the ridge crop on the earth;

b) then spreading said composition on an area equivalent to the largest circumference occupied by the seed; and

c) forming a ridge by covering the seed placed in a) with the earth prepared in step b).

6. The method according to claim 2, wherein the seed is a seed of maize, colza, sorghum, sunflower, potato, beetroot, carrot, cereals, cabbages, beans, melon, tomato, ornamental plants or even tobacco, preferably maize seed.

7. The method according to claim 1, wherein the composition comprises cypermethrin and/or natural pyrethrum.

8. The method according to claim 1, wherein the soil insects are selected from the group consisting of click beetle, grey grub, cockchafer larva, noctuids, centipede, crane fly, black vine weevil (Otiorhynchus sulcatus), flies such as seedling fly and onion fly and the maize leaf beetle, preferably click beetle.

9. The method according to claim 1, wherein the composition is used at a dose in the range from 2 to 20 kg/ha, preferably from 9 to 15 kg/ha, and very preferably of 12 kg/ha.

10. The method according to claim 1, wherein pyrethrum is present in the composition in a proportion corresponding to 2 to 12 grams of active ingredient per kilogram of composition, preferably from 6 to 10 g/kg, and very preferably from 7 to 9 g/kg.

13. The method according to claim 1, wherein the composition is ploughed into the soil by means of a diffuser comprising a hollow cylindrical or truncated body, open at both ends, one of said ends serving for fixing said diffuser to the outlet tubes of a microgranulator, and the other end being open on an inclined plane, of any shape, preferably of circular or oval shape, integral with said diffuser and making with said diffuser an angle between 35°

and 55°

, preferably between 40° and

50°

.

16. The method according to claim 1 for protection of a furrow crop against soil insects comprising the following steps:

a) making a furrow in the soil;

b) spreading said composition over the full width of the seed furrow;

c) placing seed of the furrow crop on the earth at the bottom of the seed furrow formed by the furrow, and

d) closing the furrow with the earth prepared in step b).

17. The method according to claim 1, for protection of a ridge crop against soil insects, comprising the following steps:

a) spreading said composition on an area equivalent to the largest circumference to be occupied by seed; and

b) placing seed of the ridge crop on the earth;

c) forming a ridge by covering the seed placed in b) with the earth prepared in step a).

18. The method according to claim 1 for protection of a furrow crop against soil insects comprising the following steps:

a) making a furrow in the soil;

b) simultaneously positioning seed of the furrow crop on the earth at the bottom of the seed furrow formed by the furrow and spreading said composition over the full width of the seed furrow; and

c) closing the furrow with the earth prepared in step b).

19. The method according to claim 1, for protection of a ridge crop against soil insects, comprising the following steps:

a) simultaneously positioning seed of the ridge crop on the earth and spreading said composition on an area equivalent to the largest circumference to be occupied by seed; and

b) forming a ridge covering the seed with the earth prepared in step a).

4-5. -5. (canceled)

11. A diffuser comprising a hollow cylindrical or truncated body, open at both ends, one of said ends serving for fixing said diffuser to the outlet tubes of a microgranulator, and the other end being open on an inclined plane, of any shape, preferably of circular or oval shape, integral with said diffuser and making with said diffuser an angle between 35°

and 55°

, preferably between 40° and

50°

.

12. The diffuser according to claim 11, wherein it comprises a means of attachment to the outlet tube of the microgranulator, advantageously a screw positioned perpendicularly to the central axis of the cylinder or truncated cone forming said diffuser and passing through the wall of said cylinder or truncated cone.

14. A method of treating crops at the time of sowing, wherein a composition is used, with ploughing into the soil, said composition comprising at least pyrethrum in the form of granules or microgranules, preferably in the form of microgranules.
