Description
The présent invention primarily relates to the use of herbicide combinations comprising (i) flufcnacet and (ii) diflufcnican or of a composition comprising such herbicide combinations for controlling harmful plants in tuberous root crop plants, preferably in cassava. The présent invention also relates to the use of said spécifie 5 herbicide combinations or of a composition comprising said spécifie herbicide combinations as plant growth regulators for tuberous root crop plants, preferably as plant growth regulators for cassava. Furthermore, the present invention relates to a corresponding method of controlling harmful plants in tuberous root crop plants and to a corresponding method of rcgulating plant growth of tuberous root crop plants.
Cassava (Manihot esculenta Crant?) is a major source of carbohydrate for several hundred million pcoplc, 10 mainly in Africa and to some estent in Asia and Latin Amcrica. In Africa, yiclds of cassava arc generally comparativcly low, which to a large extent is duc to cffccts of weed compétition or to uncontrolled or k unsufficicntly controlled weed growth. Hoc-wccding still is a common practice among cassava farmers.
The Procccdings ofthe 1 Ith ISRTC-AB, Kinshasa, Démocratie Republie Congo, 4-8 Octobcr 2010, pages 269275 report on the évaluation of commercially available herbicides for weed control in cassava. The treatments 15 there comprised prc-cmcrgcnt herbicides employing such as chloroacctanilidc, prometryn or S-mctolachlor.
In the Crop recommendation # 17 of the Ministry of Agriculture of Barba dos the following herbicides for weed control in cassava arc mentioned: paraquat (optionally mixed with diquat), glyphosatc, sulfosatc, pendimethalin, mctolachlor, fluazifop-butyl, sethoxydim or propaquizafop.
CN1024289I9A tcachcs a postemergcnec cassava field herbicide with mesotrion as an active component.
CN 103392724A suggests the use of a temary herbicide composition as cassava field herbicide with the active components of halosulfuron, oxyfluorfcn and an amide herbicide selected from the group of butachlor, propisochlor and mctolachlor.
G B 1,028,976 discloscs a process for the treatment of plants with storage organs, for cxamplc cassava, sweet potato or yam, which comprises spraying the plants with a substituted benzoie acid herbicide in a spécifie time 25 fram before harvest. There, herbicides like (optionally further substituted) dt-, tri- or tctrachlorobcnzotc acids arc preferred.
African Crop Science Journal 1994, 519-530 reports on weeds and their control in cassava. There, mainly the following herbicides were tested; metobromuron, fluometuron, prometryn (optionally in combination with amctrync), terbutryn, paraquat and diuron.
-2Planta Daninha, 2010,28(4), 807-816 dcscribcs the application of different hcrbicdcs on weeds in cassava. Inter alia the effects of herbicides like diuron, metribuzin, isoxaflutolc, atrazînc, ametryn, and several combinations comprising said herbicides arc reported thcrcin on two cassava varictîcs grown in the state of Paranâ, Brazil.
In their application, hcrbicidal crop protection agents (herbicides) known to date for controlling harmful plants or unwanted végétation in tuberous root crop plants hâve some disadvantages, bc it (a) that they hâve no orclsc insufficient hcrbicidal activity against spécifie harmful plants, (b) that the spectrum ofharmful plants which can bc controlled with the herbicides is not broad cnough, and/or (c) that the sclcctivity of herbicides in and the compatibility with tuberous root crop plants is too low, thereby causing unwanted damage and/or unwanted reduced harvest yiclds of the tuberous root crops.
Ovcrall, the hcrbicidal activity (above aspects (a) and (b)) and/or the sclcctivity / compatibility (above aspect (c)) of the herbicides used so far in tuberous root crop plants still allow improvement.
For the rcasons mentioned above, there still is a need for alternative, highly active herbicides or hcrbicidal compositions for the sélective application for controlling harmful plants or unwanted végétation in tuberous root crop plants.
Surprisingly, it has now been found that certain herbicide combinations or compositions comprising said herbicide combinations exhibît the desired hcrbicidal activity and arc able to sclcetivcly control harmful plants or unwanted végétation in tuberous root crop plants.
The présent invention primarily relates to the use of a combination of herbicides (herbicide combination) or of a composition comprising a combination of herbicides (herbicide combination)
- for controlling harmful plants in tuberous root crop plants, and/or
- as plant growth rcgulators in tuberous root crop plants, wherein said combination of herbicides comprises or consists of (i) flufcnacct and (ii) diflufcnican.
The présent invention further releates to the use of a composition as defined herein in the context of the présent invention which additionally comprises one or more further components selected from the group consisting of formulation auxiliarics, additîvcs customary in crop protection, and further agrochcmically active compounds (i.e. agrochcmically active compounds different from components (i) and (ii) as defined above, i.e. agrochcmically active compounds other than (i) flufcnacct and (ii) diflufcnican).
However, when a combination of herbicides used in the context of the présent invention consists ofherbicides (ï) flufcnacct and (ii) diflufcnican, this mcans that in such a case the combination of herbicides used in the context
ofthe présent invention or the composition comprising said combination of herbicides used in the context ofdie présent invention does not contain any further (i.e. no additional) herbicidal active ingrédient, and preferably does not contain any further agrochcmically active compound.
In this context, the term “further herbicidal active ingrédient and “further agrochcmically active compound” refers to the herbicides and agrochcmically active compounds (pesticides), respectively, listcd in The Pesticide Manual, I6th édition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2012 other than flufcnacct and diflufenican.
The herbicide combinations and the compositions comprising said herbicide combinations used in accordance with the présent invention not only exhibit an excellent herbicidal activity in controlling harmful plants or 10 unwanted végétation in tuberous root crop plants, but also show compatibility with tuberous root crop plants,
i.c. said herbicides do not cause sîgnificant damage (like phytotoxicity) and/orunwanted reduced harvest yiclds of the tuberous root crops.
The herbicide combinations used in accordance with the présent invention and the compositions comprising said herbicide combinations used in accordance with the présent invention allow excellent (total) weed control at an 15 agronomically acceptable level of damage of the tuberous root crop plants. Further, die type ofdamageobserved with the herbicide combinations and the compositions comprising said herbicide combinations used in accordance with the présent invention is not noticcably harmful, and the tuberous root crop plants afïected largcly or fully rccovcr from said type of damage. For examplc, in the biological exemples hcrcinbclow, no phytotoxicity effects were observed after treatment of the cassava plants with a composition comprising a 20 herbicide combination used in accordance with the présent invention.
Further, the herbicide combinations used in accordance with the présent invention and the compositions comprising said herbicide combinations used in accordance with the présent invention can bc used as plant growth regulators for tuberous root crop plants, preferably as plant growth regulators for cassava, thereby increasing harvest yiclds tuberous root crop plants (in particular the weight of the tuberous root) and/or 25 increasing the plant growth of the tuberous root crop plants (in particular the growth of the lcavcs of the tuberous root crop plants), in each case în comparison to tuberous root crop plants not treated with herbicides (untreated control).
The présent invention preferably relates to the use of a combination of herbicides or of a composition comprising a combination of herbicides as defined in the context of the présent invention, wherein the tuberous 30 root crop plants are selected from the group consisting ofsweet potato (tpomoea batatas), cassava (Manihot esculenta), and yam (plant species in the genus Dioscorea), more preferably wherein the tuberous root crop plant is cassava (Manihot esculenta).
The herbicides used in the context of the présent invention arc known per se, and described inter alia in The Pesticide Manual, 16th édition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2012 and the literaturc cited thcrcin. The herbicides used in the context of the présent invention are described in more detail hcrcinbclow.
The herbicide combinations used in the context of the présent invention and also certain compositions comprising the herbicide combinations used in the context ofthe présent invention as such arc known. The herbicide combinations used in the context ofthe présent invention and also certain compositions comprising the herbicide combinations used in the context of the présent invention arc commcrcially available.
Tuberous roots (also called root tubers) arc perennating organs, thickcncd roots that store nutrients over periods 10 when the plant cannot activcly grow, thus permitting survival from one ycar to the next.
Tubers should not be confuscd with tuberous roots. Tubers arc modified shoots, whereas tuberous roots are modified roots.
Λ tuberous root is a modified latéral root, enlarged to fonction as a storage organ. The enlarged area ofthe roottuber, or storage root, can be produced at the end or middlc of a root or involvc the entire root It îs thus different 15 in origin but similar in fonction and appcarancc to a stem tuber. Exemples of plants with notabletuberous roots include the sweet potato, cassava, yam and dahlia.
Cassava (Manihot esculenta Crantz). also called manioc, yuca, balinghoy or kamoteng kahoy (in the Philippines), tabolchu (in Northeast India), mogo (in Africa), mandioca, tapioca-root, kappa (prcdominantly in India) and manioc root, a woody shrub of the Euphorbiaccac (spurge) family native to South Amcrica, is 20 cxtcnsivcly cultivated as an annual crop în tropical and subtropical régions for its cdiblc starvhy tuberous root, a major source of carbohydrates. Cassava, when dried to a powdcry (or pearly) extract, is called tapioca; its fermented, flaky version is named garri.
Cassava is the third largest source of food carbohydrates in the tropics, after rice and maize. Cassava is a major staplc food in the developing world, providing a basic dict for over half a billion pcoplc. It is one of the most 25 drought-tolcrant crops, capable ofgrowing on marginal soils. Nigeria is the world’s largest produccr of cassava, while Thailand is the largest exporting country of dried cassava.
Cassava grows poorly in weedy ficlds and consequently produccs fewer and smaller storage roots.
Yam is the common name for some plant species in the genus Dioscorea (family Dioscorcaceac) that form cdiblc tubers. These are pcrcnnial hcrbaccous vincs cultivated for the consumption of their starchy tubers in 30 Africa, Asia, Latin Amcrica, the Caribbean and Occania. There arc many cultivars ofyam. Although some varictics of sweet potato {Ipomoea ha ta ta v) arc also called yam in parts of the United States and Canada, it is not part ofthe family Dioscorcaceac.
Yams arc monocotylcdons, related to lilics and grasses. Native to Africa and Asia, yam tubers vary in size from that of a small potato to over 60 kilograms. There are over 600 varictics of yams and 95 percent of these crops arc grown in Africa.

The use of a herbicide combination used according to the présent invention and the use of a composition comprising a herbicide combination used in the context of the présent invention is characterized by a rapidly commcncing and long-lasting herbicidal action.
In particular when the herbicide combinations as defined in the context of the présent invention and the compositions comprising a herbicide combination as defined in the context of the présent invention arc cmployedapplication rates may be reduced, a broader spectrum of broad-lcaved weeds and grass weeds maybc controlled, the herbicidal action may takc place more rapidly, the duration ofaction may be longer, the harmful
plants may bc controllcd better while using only one, or fcw, applications, and the application period which is possible to bc extended.
The abovementioned properties and advantages arc of benefit for weed control practice to keep agricultural crops free from undesired compcting plants and thus to safeguard and/or increase the yields from the qualitative 5 and quantitative point of view. These novel combinations markcdly cxcccd the technical state of the art with a view to the properties described.
While the herbicide combinations according to the présent invention hâve an outstanding herbicidal activity against monocotylcdonous and dtcotylcdonous weeds, the crop plants arc damaged only to a minor extent, ifat ail.
Morcover, some of the compositions according to the présent invention hâve outstanding growth-rcgulatory properties on the crop plants. They engage in the plants’ metabolism in a rcgulatory manner and can thus bc employed for provoking directed cffccts on plant constituent» and to facilitate harvesting such as for example by triggering dcsiccation and stunted growth. Morcover, they arc also suitable for the general control and inhibition of undesired végétative growth without simultancously destroying the plants. An inhibition ofvégétative growth 15 is very important in a large number of monocotylcdonous and dicotylcdonous crops sincc yield fosses as a rcsult of lodgîng can thus bc reduced, or prcvcntcd complctcly.
Owing to their herbicidal and plant-growth-rcgulatory properties, the compositions according to the présent invention can bc employed for controlling harmful plants in genetically modified crop plants or crop plants obtained by mutation/sclcction. Thèse crop plants arc distinguished as a rulc by particular, advantageous 20 properties, such as résistances to herbicidal compositions or résistances to plant diseases or causativc agents of plant diseases such as particular insects or microorganisms such as fungi, bactcria or viniscs. Other particular properties relate, for example, to the harvested material with regard to quantity,quality, storability, composition and spécifie constituent». Thus, for exemple, transgenic plants arc known whosc starch content is increased or whosc starch quality i.s altcrcd, or those where the harvested material has a different fatty acid composition.
The tuberous root crop plants can also hâve been genetically modified or been obtained by mutation sélection. For example, WO 97/44473 Al relates to transforming and producing cassava plant (protoplasts). WO 92/05259 Al dcscibcs transgenic plants having modified carbohydrate content, inter alia cassava plants.
The présent invention also relates to a method of controlling undesired végétation (e.g. harmful plants) in tuberous root crop plants, which comprises applying a herbicide combination and compositions as defined in the 30 context ofthe présent invention or applying a composition comprising a herbicide combination as defined in the context ofthe présent invention, for example by the prc-cmcrgcncc method, by the post-émergence methodor by the prc-cmcrgcncc and the post-cmcrgcncc method, to the plants, for example harmful plants, parts of these plants, plant sccds or the area where the plants grow, for examplc the area under cultivation.
