Use of seed flour as soil pesticide
Use of vegetable seed flour, in particular Brassicaceae flour, as a cytotoxic agent with improving action.
1. A method of killing soil pathogens and soil parasites comprising
a contact step, during which at least one of a soil pathogen and a soil parasite is contacted with a composition comprising a seed flour containing at least one glucosinolate and the enzyme myrosinase, wherein the seed flour contains a seed selected from the group consisting of seeds of Brassica carinata A. B., seeds of Capparaceae , and seeds of Barbarea verna ; wherein the seed flour has been de-oiled at a temperature below 75° C.; and
a release step, during which hydrolysis of the glucosinolate takes place in the presence of water so that isothiocyanates are released from the composition to at least one of the soil pathogen and soil parasite.
2. The method of claim 1 , wherein the soil parasites are selected from the group consisting of nematodes and wireworms.
3. The method of claim 1 , wherein the soil parasites are selected from the group consisting of weeds and insects.
4. The method of claim 1 , wherein the parasites are selected from the group consisting of Fusarium clumorum, Meloidogyne incognita (Kofoid and White) Chitwoody, Agriotes sordidus, Agriotes utulatus , and Agriotes brevis.
5. The method of claim 1 , wherein the flour is fungitoxic to a fungi of the genus Fusarium.
6. A method of improving soil comprising a contact step, during which a soil is contacted with a seed flour containing at least one glucosinolate and the enzyme myrosinase, wherein the seed flour is toxic to at least one organism selected from the group consisting of a nematode, a wireworm, a weed, an insect, Meloidogyne incognita (Kofoid and White) Chitwoody, Agriotes sordidus, Agriotes utulatus , and Agriotes brevis , and a fungi of the genus Fusarium ; wherein the seed flour has been de-oiled; and
a release step, during which hydrolysis of the glucosinolate takes place in the presence of water so that isothiocyanates are released from the composition to the organism.
7. The method of claim 6 , wherein the seed flour has been de-oiled at a temperature below 75° C.
8. The method of claim 6 , and further comprising an identification phase to identify the seed flour containing at least one glucosinolate and at least one enzyme selected from the group consisting of glucosidasic enzymes and thioglucosidasic enzymes.
9. The method of claim 8 , wherein the at least one enzyme is myrosinase.
10. A method of improving soil comprising
a contact step, during which the soil is contacted with a flour made from at least one seed selected from the group consisting of seeds of Brassica carinata A. B., seeds of Capparaceae , and seeds of Barbarea verna wherein the flour has been de-oiled at a temperature below 75° C.; and
a release step, during which isothiocyanates are released from the composition into the soil.
11. The method of claim 10 , wherein the flour is toxic to at least one organism selected from the group consisting of a nematode, a wireworm, a weed, an insect, Meloidogyne incognita (Kofoid and White) Chitwoody, Agriotes sordidus, Agriotes utulatus , and Agriotes brevis , and a fungi of the genus Fusarium.
12. A method of improving soil comprising
a contact step, during which the soil is contacted with a composition comprising a seed flour containing at least one glucosinolate and enzyme myrosinase, wherein the seed flour contains a seed selected from the group consisting of seeds of Brassica carinata A.B., seeds of Capparaceae , and seeds of Barbarea verna ; wherein the seed flour has been de-oiled; and
a release step, during which hydrolysis of the glucosinolate takes place in the presence of water so that isothiocyanates are released from the composition into the soil.
13. The method of claim 12 , wherein the seed flour has been de-oiled at a temperature below 75° C.
14. The method of claim 13 , wherein the seed flour has been de-oiled at ambient temperature.
15. The method of claim 12 , wherein the seeds comprise seeds of Brassica carinata A.B.
16. The method of claim 12 , wherein the seeds comprise seeds of Capparaceae.
17. The method of claim 12 , wherein the seeds are of at least two different vegetable varieties.
18. The method of claim 1 , wherein the seeds comprise seeds of Brassica carinata A.B.
