Use of termite powder for the biological control of parasitic plants. Use of termite powder according to claim 1, wherein the parasitic plants are hemiparasitic plants. Use of termite powder according to claims 1 or 2, wherein hemiparasitic plants are selected from the family group consisting of Custaceae, Lauraceae, Orobanchaceae, Loranthaceae and Viscaceae, preferably Orobanchaceae. Use of termite powder according to anyone of claims 1 to 3, wherein hemiparasitic plants of the Orobanchaceae family group are selected from the genus group consisting of Alectra spp., Striga spp., preferably Striga spp.. Use of termite powder according to anyone of claims 1 to 4, wherein hemiparasitic plants of the Striga spp. genus group are selected from the species group consisting of Striga asiatica, Striga hermonthica, Striga Aspera, Striga forbesii, Striga Generioides, preferably Striga hermonthica. Use of termite powder according to anyone of claims 1 to 5, wherein the termite powder is sampled from termites of the Cubitermes genus. Use of termite powder according to anyone of claims 1 to 6, wherein the termite powder is in association with a substrate and thus constituting an inoculum. Use of termite powder according to anyone of claims 1 to 7, wherein the ratio termite powder versus substrate is comprised from about 0.01 (w:v) to about 0.1 (w:v), preferably from about 0.05 (w:v) to about 0.1 (w:v), and more preferably 0.1 (w:v). Use of termite powder according to anyone of claims 1 to 8, in spaces intended for cultures, particularly cultures of cereals. Use of a composition comprising:
a. termite powder, the particles size constituting said powder being comprised from about 100 µm to 1000 µm and preferably from about 100 µm to about 500 µm,b. said substrate chosen among the natural culture soil, the compost arising from culture residues,
the ratio termite powder: substrate being comprised from about 0.01 (w:v) to about 0.1 (w:v), preferably from about 0.05 (w:v) to about 0.1 (w:v), and more preferably 0.1 (w:v). Use of a composition according to claim 10, wherein the termite powder is sampled from termites of the Cubitermes genus. Process of biological control of parasitic plants in spaces intended for cultures, particularly cultures of cereals, comprising a step of introducing an inoculum in spaces intended for cultures to be treated, the inoculum being prepared by mixing the termite powder with a substrate, said powder being eventually crushed. Process according to claim 12, wherein the powder consists of particles size having a size comprised from about 100 µm to 1000 µm and preferably from about 100 µm to about 500 µm. Process according to claim 12 or 13, wherein the termite powder is sampled from termites of the Cubitermes genus. Process according to anyone of claims 12 to 14, comprising a step of preparation of the inoculum by mixing said termite powder with a substrate, said substrate being chosen among the natural culture soil, the compost arising from culture residues, the ratio termite powder: substrate being comprised from about 0.01 (w:v) to about 0.1 (w:v), preferably from about 0.05 (w:v) to about 0.1 (w:v), and more preferably 0.1 (w:v). Process according to anyone of claims 12 to 15, comprising a step of introduction of the inoculum in spaces intended for cultures, at doses comprised from about 17 to 170 ml of inoculum per unit element of culture, preferably from about 17 to 85 ml of inoculum, more preferably from about 85 to 170 ml of inoculum, and more preferably at a dose of 170 ml of inoculum, said unit element of culture being particularly a seed or a plant. Process according to anyone of claims 12 to 16, wherein a seed is sown or a plant is transferred per dose of inoculum introduced in the spaces intended for cultures. Process of biological control of parasitic plants according to anyone of claims 12 to 17 comprising the following steps :
a. sampling and eventually crushing termite powder, the particles size of said powder having a size comprised from about 100 µm to 1000 µm and preferably from about 100 µm to about 500 µm,b. preparing an inoculum by mixing said powder with a substrate, said substrate being chosen among the natural culture soil, the compost arising from culture residues, the ratio termite powder: substrate being comprised from about 0.01 (w:v) to about 0.1 (w:v), preferably from about 0.05 (w:v) to about 0.1 (w:v), and more preferably 0.1 (w:v),c. introducing the inoculum in spaces intended for cultures, at doses comprised from about 17 ml to 170 ml of inoculum per unit element of culture, preferably from about 17 ml to 85 ml of inoculum per unit element of culture, preferably from about 85 ml to 170 ml of inoculum per unit element of culture, and more preferably 170 ml of inoculum per unit element of culture,d. sowing a seed or transferring a plant in spaces intended for cultures containing said inoculum.
