Definitions
- the present invention relates to herbicidal compositions. More specifically, the subject of this invention relates to a composition comprising a known compound belonging to the family of chloroacetamides, mixed with a known compound, belonging to the family of isoxazolidinones.
- the first of these compounds is chloroacetamide called "propisochlor”: it penetrates through the underground organs of weeds during germination or at the seedling stage. On the one hand, it inhibits the synthesis of proteins and nucleic acids, on the other hand it inhibits root growth. The reduction in osmotic potential resulting from these actions causes the rapid death of weeds.
- the second active compound of the composition according to the invention is isoxazolidinone called "clomazone"; this active agent inhibits the biosynthesis of carotenoids; the target enzyme is not clearly defined. It is a selective herbicide absorbed by the roots and shoots and translocated to the aerial organs. Weeds, which are sensitive, emerge but do not have pigmentation.
- the clomazone molecule belongs to a group of active agents for which few cases of resistant weeds are known; for clomazone, only the resistance of a population of Loliumrigidum in Australia in 1982 is known.
- Propisochlor has been tested on a very large number of crops; it has been found to be very interesting for many of the crops tested, particularly for maize, sunflower and rapeseed.
- the weeds that we encounter on these crops and on which propisochlor allows an interesting control are mainly:
- grasses Echinochloa crus-galli; Setariasp; Digitariasanguinalis, Apera spica venti; Poaannua; Sorghumhalepense;
- Propisochlor can be applied at different key stages of the crop, ie pre-planting (with incorporation into the soil), post-sowing / pre-emergence, which is its preferred or post-emergence position. early on maize, the application of the herbicide to be carried out "around sowing” on weeds not yet emerged or at a very young stage.
- propisochloretant absorbed by the weeds in their roots or by all underground parts for germinating seeds the effectiveness of the product is highly dependent on the soil moisture, and therefore the rains that may occur after the application, because the herbicide is absorbed via the liquid phase of the soil. Due to its root action, propisochlor has the ability to control unleavened weeds during processing; the persistence of product is estimated at 2 to 3 months depending on the type of soil and climatic conditions.
- the product acts by inhibiting elongases and cyclization enzymes of geranyl-geranyl pyrophosphate, which lead to gibberellins.
- Propisochlor belongs to a group relatively unaffected by resistance problems, which gives it great interest. Some rare cases of resistance to molecules of this group of herbicides have been detected, for example resistances of Echinochloa crus-gallia.u butachlor in China, butachlor and propanil in Thailand, resistance of Loliummultiflorum to flufenacet in the USA and the Loliumrigidum with metolachlor in Australia.
- propisochlor does not control all the weeds present in the crops, so it has already been proposed to associate it with a partner, for example amicarbazone for maize or dimethenamid-P for rapeseed crops.
- a partner for example amicarbazone for maize or dimethenamid-P for rapeseed crops.
- Such an association has also been considered as possible in the European Patent No. EP 2 094093 without however specify for which crops and without any example to define what results could be expected from such an application
- the present invention therefore relates to a herbicidal composition
- a herbicidal composition comprising a component [A] and a component [B], wherein the component [A] is the known compound propisochlor of formula (I):
- the ratio R A / B between the amount by weight of the component [A] and the amount by weight of the component [B] is in the range from 10 to 40, preferably from 20 to According to another variant, the component application amounts [A] are in the range from 500 to 2200 g / ha (ha is the abbreviation of hectare, ie 10,000 m2).
- the application amounts of component [B] are in the range of 60 to 90 g / ha.
- composition according to the invention may be in the form of dry powders, wettable powders, emulsifying concentrates, microemulsions, pastes, granules, water-dispersible granules, solutions, suspensions, microcapsules.
- composition according to the invention may consist of formulation (s) already prepared (s) containing, in the desired quantities, the component [A] and the component [B]; or it can be obtained at the time of use, by mixing the relative amounts of separately formulated component [A] and component [B].
- composition according to the invention may comprise other subsequent active ingredients such as other herbicides, antidotes, fungicides, insecticides, acaricides, fertilizers.
- the said other herbicide (s) can be selected (s) in the following list: acifluorfen, aclonifen, AKH-7088, amicarbazone, amitrole, anilofos, azafenidine, azimsulfuron, aziprotryne, BAY MKH 6561, benazoline, benfluralin, bensulfuron, bentazone, bensfendizone, benzofenap, benzthiazuron, bifenox, balanceafos, bispyribac-sodium bromacil, bromofenoxim, butafenacil, butamifos, butenachlor, butralin, butroxydim, butylate, cafenstrole, carbetamide, chlomethoxyfen, chloramben, chlorbromuron, chlorbufam, chlorflurenol,
- the active substances including [A] and [B] may constitute from 1 to 90% by weight, and preferably from 5 to 75% by weight, relative to the total weight of the composition.
- the invention also relates to the use of at least one herbicidal composition as defined above for the control of weeds in agricultural crops.
- Such use can be made for post-emergence and / or pre-emergence control of monocotyledonous and dicotyledonous weeds and / or for the treatment of agricultural crops, meadows, lawns and / or for treatment as a total herbicide in applications. pre-seeding or in the weeding of industrial zones, railways, monuments.
- Such use may be made, in particular, for the control of plants or weeds of the following list: Abutilon theophrasti, genera Adonis, genera Ambrosia, genera Amaranthus, Amnimaius, Anagallis arvensis, genera Anthemis, Aphanesarvensis, Atriplexpatula, Bidenspilosa, Capsellabursa pastoris , Chenopodium album, Convolvulus sepium, Datura stramonium, Euphorbia genera, Fumariaofficinalis, Galeopsis tetrahit, Galinsogaciliata, Galium aparine, Geranium genera, Helianthus genera, Ipomeas genera, KochiaScoparia, Lamium genera, Linderniaprocumbens, Matricaria genera,
- Seneciovulgaris Sesbania exaltata, Sida spinosa, Sinapisarvensis, Solanumnigrum, genera Sonchus, Stellaria media, Thlaspi arvense, genera Veronica, genera Vicia, genera Viola, genera Xanthium, Aegilops tauschii, Alisma plantago, Alopecurusmyosuroid.es, genera Apera, Avenafatua, genera Brachiaria, genera Bromus, Butomusumbellatus,

- the invention finally relates to a method for controlling weeds in agricultural crops by applying at least one composition according to the invention.
- clomazone is added to the solvent and stirred until completely dissolved; propisochlor is then added and stirred until a clear solution is obtained; the two emulsifiers are then added to the mixture, followed by the rapeseed oil, and the mixture is homogenized.
- the product as well obtained is stable and does not crystallize when stored at -10 ° C for 7 days.
- test products are made to react by spraying the products at the dosages indicated in the 1st column of Tables I to III which follow (for example 2 or 2.5 or 3 1 / ha for the product [X]). Spraying is carried out post-sowing from 10 different weeds whose names are given in the first three rows of Tables I to III (four replicates (pots or trays) per weed). These tests were carried out near Nîmes (France) under controlled conditions, with a temperature and soil moisture maintained at optimum. The efficiencies were recorded at 14, 23 and 30 days (only 8 weeds raised for 14 days, and 9 for 23 days).
