Definitions

  • the present invention relates to the technical field of the protection of agricultural crops (poaceae, solanaceae, brassicaceae, asteraceae) vis-à-vis holoparasites plants and epirhized hemiparasites (that is to say that develop on the roots of their plant host), of the order Scrophulariales, and in particular Striga and Orobanche. More specifically, the invention relates to the use of a dicarboxylic acid having 2 to 5 carbon atoms or a strain Azospirillum brasilense L4 deposited under the number 1-4830 with the CNCM to fight against the growth of holo plants or hemiparasites.
  • Holoparasite plants are non-chlorophyllian parasitic plants in nature and therefore need to take their organic matter from a host plant.
  • the hemiparasitic plants are chlorophyllian parasitic plants that provide only part of the synthesis of the carbonaceous substances necessary for their development. These parasitic plants develop at the expense of their host by becoming attached to their roots via the formation of a haustorium (sucker ) which results in the establishment of a connection between the xylem conducting vessels of the host plant and the parasitic plant (Bouwmeester et al., 2003, Curr Opin Plant Plant, 6: 358-364).
  • parasitic plants will pump sap from the host plant, slow down the development of aerial parts, induce chlorosis and reduce photosynthesis (Ejeta and Butler, 2000. Parasitic plants, Irr RA Frederiksen and GN Odvody (eds) Compendium of Sorghum Diseases, 2nd Edition, APS Press, The American Phytopathological Society, pp. 53-56). To survive, these parasitic plants must produce a large amount of seeds. Thus, as soon as the aerial parts emerge, the parasitic plant flowers and produces enormous quantities of seeds that may remain viable in the soil for several years (Haussmann et al., 2000, Reld Crop Res., 66: 195-211). .
  • the plants of the Striga and Orobanche genera belong to the same order, that of the Scrophulariales, but do not belong to the same family (the plants of the genus Striga belong to the family Scrophulariaceae and are hemiparasites, while plants of the genus Orobanche belong to the family Orobanchaceae and are holoparasites). These plants have many points in common: small seeds facilitating their dissemination, germination dependent on the presence of strigolactone elicitors, trophic spoliation of the host plant via the development of a haustorium.
  • Striga in all tropical and subtropical regions of the world and in particular in sub-Saharan Africa and Orobanche, mainly in the temperate countries of Asia and Central Europe and in particular around the Mediterranean. They affect the growth of a very wide variety of plants of agronomic interest (maize, rice, sorghum, millet, sunflower, rapeseed, tobacco, tomato, etc.), whether in temperate (Orobanche), or tropical (Striga ). They cause significant yield losses on a large number of crops.
  • the seeds of these parasitic plants are of very small size which favors their propagation over long distances by the wind, the animals, or by contaminated agricultural machinery.
  • the transport of seed from infected host plants is also a source of dissemination.
  • crop protection against Orobanche or Striga plants involves the use of non-selective herbicides, coupled with the use of cereal varieties resistant to these herbicides (De Groote et al., 2008, Agric. System 97: 83-94).
  • These chemical control means in addition to their toxicity to the environment, are expensive.
  • the use of plant protection products including herbicides will be greatly reduced.
  • Strigae or Fusarium art rosporioides that produce mycotoxins (ie fusaric acid, fumonisins, and deoxynivalenol (DON)) (Amsellem et al., 2001, BioControl 46: 211-228, Abuelgasim and roschel, 2003, FAO plant production and protection. Paper IMo.120. Addendum 1, 109-144; Lendzemo et al. 2004 Field Crop es. 91: 51-61; Venne et al., 2009, PesL Manag. Sci. 65: 572-580).
  • Mycotoxins are able to inhibit the germination of Striga and Orobanche seeds, but they can trigger health problems in mammals. In particular, they represent a risk for cattle and human food and therefore can not be considered as completely harmless substances.
  • the present invention proposes to use a dicarboxylic acid containing from 2 to 5 carbon atoms to combat growth of holo plants or hemiparasites, and in particular to control the growth of plants of the genus Striga and / or plants of the genus Orobanche. It is also possible to use combinations of several dicarboxylic acids, having 2 to 5 carbon atoms, to control the growth of holo plants or hemiparasites, to obtain the desired effect.
  • the active agents proposed for inhibiting the development of holo or hemiparasite plants are chosen from dicarboxylic acids (hereinafter also called diacids) comprising from 2 to 5 atoms. of carbon.
  • diacids comprise two carboxylic acid functions that are directly linked together, in the case of oxalic acid, or linked by a saturated or unsaturated carbon chain comprising 1, 2 or 3 carbon atoms.
  • This carbon chain is preferably linear and may be unsubstituted or substituted with one or more substituents, in particular of OH, OCH 3 and CH 2 OCH 3 type .
  • oxalic acid By way of example of such diacids, mention may be made of oxalic acid, malonic acid, maleic acid, malic acid, glutaric acid, and acetylene dicarboxylic acid.
  • L-form malic acid which has been shown to be particularly active in inhibiting the growth of Striga or Orobanche plants, is preferred.
  • Malic acid in L form could be isolated, by the inventors, from culture supernatant of a bacterial strain, Azospirillum brasilense L4, deposited, in accordance with the Budapest Treaty of 1977, under the number 1-4830, the December 18, 2013, at the CNCM, National Collection of Cultures of Microorganisms, Institut Pasteur, 25 rue Dondel Roux, 75724 Paris Cedex 15, FRANCE. This strain was isolated in 1995 from a sorghum field infested with a Striga parasitic plant in Mali.
  • the Azospirillum brasilense strain L4 that has been reported as having the ability to inhibit in vitro the growth of Striga hermonù AC and Orobanche ramosa and in soil microcosms, protect vis-a-vis sorghum and Striga to stimulate the growth of the cereal (Bouillant et al., 1997, CR Acad III Life Sci 320: 159-162, Miche et al., 2000, Eur J. Plant Pathol. 106: 347-351) has now been filed under the number 1-4830 with the CNCM (National Collection of Cultures of Microorganisms, France).
  • This strain produces in culture very specific metabolites, compared with other strains of Azospirillum brasilense (and especially with respect to that reported by Dadon et al., 2004: Isr. J. Plant Sci. 52: 83-86). .
  • the inventors have analyzed the culture supernatant of the strain Azospirillum brasilense L4, deposited under the number 1-4830, with the CNCM (National Collection of Cultures of Microorganisms, France) and have was able to demonstrate that malic acid in L form is responsible for the herbicidal activity observed with holo or hemiparasite plants.
  • the malic acid in L form is not the major component present in the culture supernatant of the bacterial strain, Azospirillum brasilense L4, deposited under the number 1-4830 with the CNCM (National Collection of Cultures of Microorganisms, France).
  • the inventors have also demonstrated that this herbicidal activity observed with respect to holo or hemiparasite plants is generalizable to the chemical class of dicarboxylic acids comprising from 2 to 5 carbon atoms.
  • the invention therefore proposes using active agents of natural origin, with a low environmental impact, to limit, inhibit the growth of parasitic plants.
  • dicarboxylic acids comprising from 2 to 5 carbon atoms are also capable of inhibiting the elongation of procaulomas or radicles. from germinated seeds of the parasitic plant, and, therefore, to block the growth of the parasitic plant, as is apparent in particular from the data presented in Table 1 below.

  • a solution comprising from 1 to 20 g of dicarboxylic acid per liter of solution may be used.
  • the dicarboxylic acid can be applied to seeds and / or plant plants or crops to be protected.
  • the herbicidal compositions containing a dicarboxylic acid according to the invention may in particular be in the form of aqueous solutions or granules. These compositions may contain, in addition to the active dicarboxylic acid, ions derived from K 2 HPO 4 or KH 2 PO 4 , one or more fillers such as silica, clay, kaolin or talc and one or more surfactants. such as dodecylbenzene or calcium lignosulfonate.
