摘要
(FR2760600) The invention concerns an original live bionematicide composition (NOVI-BIOTEC-7996), with an essentially ovicide activity, efficient against various parasitic nematodes in the soil, in open fields, in orchards and in greenhouses.  NOVI-BIOTEC-7996 consists of a compatible bacterial combination with complementary and synergistic ovicide effect on the resistance and preservation stages of these parasites in the soil.  This invention also concerns a method for the mass production, formulation and application of NOVI-BIOTEC-7996 in different conditions.  NOVI-BIOTEC-7996 is particularly useful for protecting plants and other hosts likely to be infested by various nematodes, while reducing the potential inoculum of soils or treated substrates.

主权利要求
(FR2760600) 1. Alive Bionematicide (indicated NOVI-BIOTEC-7996), with synergistic action ovicide on the stages of conservation of various groups of parasitic nematodes and bacteriophages in the ground, characterized in that it is composed of at least two compatible, indicated bacterial strains “BTA” and “BSM”. 2. Bionematicide according to claim 1, characterized in that stocks “BTA” and BSM” are respectively selected among the stocks of Bacillus thuringiensis and Bacillus sphaericus. 3. Bionematicide according to claim 2, characterized in that the stock “BTA”, which returns in its composition, acts primarily on the degradation of the hull of egg of the nematodes by disturbing the blossoming of the larvae and affecting the viability of eggs. 4. Bionematicide according to claim 2, characterized in that the stock “BSM”, which returns in its composition, acts primarily on the mortality of the embryonic stages inside egg of the nematodes, its action being supported and being amplified in the presence of “BTA”. 5. Bionematicide according to one of claims 1 to 4, characterized in that it preferentially consists of 20 to 50 p. 100 of “BTA” and 50 to 80 p. 100 of “BSM”. 6. Production of the bionematicide defined in the one of claims 1 to 5, characterized in that it is made in mass preferably in simple liquid medium in a fermenter of more or less great capacity. 7. Proceeded of preparation according to claim 6 of the bionematicide according to one of claims 1 to 5, characterized in that it comprises the following stages: (I) Mass production on an agitated liquid medium, bases of extract of Cicer arietinum (Leguminous) and saccharose; (II) Freeze-drying of the bacterial suspension obtained after or before adding a dampener and a neutral support; (III) Conservation of the extract in huile de paraffine. 8. Preparation according to claim 7, characterized in that the temperature of the culture on agitated liquid medium is of 8 with 48°C, preferably of 20 with 35°C, and in what the pH is from 6 to 8, preferably from 6,0 to 7,5. 9. Process according to one of claims 6 to 8 characterized in that the biomass on liquid culture allows obtaining at least 0,5 p. 100 of dry extract after freeze-drying. 10. Method of application of the bionematicide according to one 11. Claims 1 to 5, characterized in that the amount used is from 10 to 20 ml of the bacterial suspension (or the equivalent in the form of dry extract) and in what the finished product can be either applied in suspension or prepared for a longer conservation.
