Definitions
- Plant health compositions comprising a beneficial microorganism and a pesticide
- the present invention relates to plant health compositions comprising, as active components, at least one viable microorganism having plant health activity and at least one chemical compound having plant health and/or crop protection activity; methods for controlling phytopathogenic harmful pests and methods for improving plant health by applying such plant health compositions; plant health formulations prepared from said compositions; kits comprising said plant health compositions as well as plant seeds treated with such compositions or formulations.
- the present inventors were looking for new solutions of the above problem.
- plant health composition comprising the following components: 1 ) at least one viable microorganism (I) having plant health activity, and 2) at least one chemical compound (II) having plant health activity and/or crop protection activity.
- compositions of the components 1 ) and 2) allow a more significant improvement of plant health than is possible with the microbial strains (I) on the one hand and with the individual compounds (II) on the other hand alone (synergistic combinations).
- Component 1 embraces not only the isolated, pure cultures of a microbial strain, but also their suspensions in a whole broth culture or a metabolite-containing supernatant or a purified metabolite obtained from a whole broth culture of the strain.
- Whole broth culture refers to a liquid culture containing both cells and media.
- Supernatant refers to the liquid broth remaining when cells grown in broth are removed by centrifugation, filtration, sedimentation, or other means well known in the art.
- metabolite refers to any compound, substance or byproduct of a fermentation or a microorganism that has plant health activity.
- Propagules of a plant are all types of plant propagation material. The term embraces seeds, grains, fruit, tubers, rhizomes, spores, cuttings, offshoots, meristem tissues, single and multiple plant cells and any other plant tissue from which a complete plant can be obtained. One particular propagule is seed.
- Locus means soil, area, material or environment where the plant is growing or intended to grow.
- Plant embraces individual plants or plant varieties of any type of plants, in particular agricultural, silvicultural and ornamental plant.
- Pests comprise in particular herbs, fungi, nematodes, molluscs, bacteria, viruses or insects harmful to a plant.
- Pesticides comprise herbicides, fungicides, nematicides, molluscicides, bactericides and insecticides.
- Plant health is intended to mean a condition of the plant, which is determined by several aspects alone or in combination with each other.
- One indicator for the condition of the plant is the “crop yield ".
- Crop” and “fruit” are to be understood as any plant product which is further utilized after harvesting, e.g. fruits in the proper sense, vegetables, nuts, grains, seeds, wood (e.g. in the case of silviculture plants), flowers (e.g. in the case of gardening plants, ornamentals) etc., that is anything of economic value that is produced by the plant.
- Another indicator for the condition of the plant is the "plant vig- our”. The plant vigour becomes manifest in several aspects, too, some of which are visual appearance, e.g.
- leaf colour, fruit colour and aspect amount of dead basal leaves and/or extent of leaf blades, plant weight, plant height, extent of plant verse (lodging), number, strongness and productivity of tillers, panicles' length, extent of root system, strongness of roots, extent of nodulation, in particular of rhizobial nodulation, point of time of germination, emergence, flowering, grain maturity and/or senescence, protein content, sugar content and the like.
- Another indicator for the condition of the plant is the plant's "tolerance or resistance to biotic and abiotic stress factors".
- Crop protection is intended to mean a control effect, as for example the prevention, reduction or elimination of at least one crop disease, fungus or other pest.
- a chemical compound having crop protection activity thus may prevent the onset and/or spread of at least one fungus or other pest at, on or in at least one crop, which otherwise might cause serious damage to the crop resulting, for example, in a loss of yield.
- a substance or microorganism having "plant health activity” has a beneficial, advantageous effect on at least one of the above indicators.
- Biotic and abiotic stress can have harmful effects on plants.
- Biotic stress is caused by living organisms, such as pests (e.g. insects, arach- nides, nematodes etc.), competing plants (for example weeds), phythopathogenic fungi and other microorganisms such as bacteria and viruses.
- Abiotic stress is caused for example by extremes in temperature such as heat or cold or strong variations in temperature or temperatures unusual for the specific season, drought, extreme wetness, high salinity, radiation (e.g. increased UV radiation due to the decreasing ozone protec- tive layer), increased ozone levels and organic pollution (e.g. by phythotoxic amounts of pesticides) or inorganic pollution (e.g.
- the three above indicators for the health condition of a plant may be interdependent and may result from each other.
- an increased resistance to biotic and/or abiotic stress may lead to a better plant vigour, e.g. to better and bigger crops, and thus to an increased yield.
- a more developed root system may result in an increased resistance to biotic and/or abiotic stress.
- these inter- dependencies and interactions are neither all known nor fully understood and therefore the different indicators will be described separately.
- "increased yield" of a plant, in particular of an agri- cultural, silvicultural and/or ornamental plant means that the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the composition of the invention. According to the present invention, it is preferred that the yield be increased by at least 0,5 %, more preferred at least 1 %, even more preferred at least 2 %, still more preferred at least 4 %.
- improved plant vigour means that certain crop characteristics are increased or improved by a measurable or noticeable amount over the same factor of the plant produced under the same conditions, but without the appli- cation of the composition of the present invention.
- Improved plant vigour can be characterized, among others, by following improved properties of the plant:
- the improvement of the plant vigor according to the present invention particularly means that the improvement of any one or several or all of the above mentioned plant characteristics are improved independently of the pesticidal action of the composition or active ingredients.
- "enhanced plant's tolerance or resistance to biotic and/or abiotic stress factors” means (1 ) that certain negative factors caused by biotic and/or abiotic stress are diminished in a measurable or noticeable amount as com- pared to plants exposed to the same conditions, but without being treated with the composition of the invention and/or (2) that the negative effects are not diminished by a direct action of the composition on the stress factors, e.g. by its fungicidal or insecti- cidal action which directly destroys the microorganisms or pests, but rather by a stimulation of the plants' own defensive reactions against said stress factors.
- Negative factors caused by biotic stress such as pathogens and pests are widely known and range from dotted leaves to total destruction of the plant.
- Negative factors caused by abiotic stress are also well-known and can often be ob- served as reduced plant vigour (see above), e.g. dotted leaves, "burned leaves", reduced growth, less flowers, less biomass, less crop yields, reduced nutritional value of the crops, later crop maturity, to give just a few examples.
- the tolerance of and/or resistance against biotic stress fac- tors may be enhanced.
- the inventive compositions may be used for stimulating the natural defensive reactions of a plant against a pathogen and/or a pest.
- the plant can be protected against unwanted microorganisms such as phytopathogenic fungi, bacteria or viruses and/or against pests such as insects, arachnids and nematodes, and it has been found that the inventive compositions result in plant strengthen- ing effects. Therefore, they are useful for mobilizing the plant's defense mechanisms against the attack of unwanted microorganisms and/or pests. Consequently, the plant becomes tolerant or even resistant towards these microorganisms and/or pests.
- Unwanted microorganisms in this context are phytopathogenic fungi and/or bacteria and/or viruses.
- Unwanted pests are insects and/or arachnids and/or nematodes.
- the inventive compositions may be used for stimulating the natural defensive reactions of a plant against microorganisms as for example against phytopathogenic fungi, bacteria and/or viruses, wherein the treated plant may develop increased defense mechanism against one of these pathogens or against two, three or all of these pathogens.
- the tolerance of and/or resistance against abiotic stress factors may be enhanced.
- inventive compositions may be used for stimulating a plant's own defensive reactions against abiotic stress such as extremes in temperature, e.g. heat or cold or strong variations in temperature or temperatures unusual for the specific season, drought, extreme wetness, high salinity, radiation (e.g. in- creased UV radiation due to the decreasing ozone protective layer), increased ozone levels, organic pollution (e.g. by phythotoxic amounts of pesticides) and/or inorganic pollution (e.g. by heavy metal contaminants).
- extremes in temperature e.g. heat or cold or strong variations in temperature or temperatures unusual for the specific season, drought, extreme wetness, high salinity, radiation (e.g. in- creased UV radiation due to the decreasing ozone protective layer), increased ozone levels, organic pollution (e.g. by phythotoxic amounts of pesticides) and/or inorganic pollution (e.g. by heavy metal contaminants).
- Porate comprises material present in the form of particles of any, regular or ir- regular shape and size, which particles may be individual particles or aggregates or agglomerates or compressed forms of such individual particles.
- the parameter "a w " designates the water activity (correlating with the water content of a sample)
- the measurement of water activity may be performed with a Hygroscope DT instrument from Rotronic AG, Zurich, Switzerland.
- the product is placed in the sample holder and this is positioned in the measuring chamber thermostatted to 25 0 C. After closing the measuring chamber and an equilibration time of 20 minutes, the instrument measurement value is read off.
- Cell counts may be determined in the conventional manner by serial dilution with sterile 0.9% strength NaCI solution and subsequent plating on MRS agar (Difco Laboratories). "Colony-forming units” (cfu) may be counted after incubation for 48 hours at 37 0 C. Only plates, which contained between 30 and at most 300 colonies were evaluated. Generally, 3 plates per stage were evaluated and the mean taken.
- “Viability" of a microorganism describes the ability of the microorganism to grow and/or to multiply and/ or to differentiate.
- seed embraces seeds and plant propagules of all kinds including but not limited to true seeds, seed pieces, suckers, corms, bulbs, fruit, tubers, grains, cuttings, cut shoots and the like and means in a preferred embodiment true seeds.
- seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking, seed im- pregnation and seed pelleting.
- coated with and/or containing generally signifies that the active ingredient is for the most part on the surface of the propagation product at the time of application, although a greater or lesser part of the ingredient may penetrate into the propagation product, depending on the method of application. When the said propagation product is (re)planted, it may absorb the active ingredient.
