Description

TECHNICAL FIELD

The present invention relates to aqueous compositions, to the preparation of such compositions and to a method of using such compositions for controlling insects and/or representatives of the order Acarina. The aqueous compositions of the invention have particular application in the protection of plant propagation materials, such as seeds, against insects and/or representatives of the order Acarina.

BACKGROUND

The use of synthetic insecticides to control insect pests in crops is a universal practice. This practice has gained a high degree of commercial success because it has been shown that such control can increase crop yield. However, effective use of insecticides requires sound management in view of insect resistance and environmental and worker exposure concerns. One solution applied to this problem has been the provision of new, more highly active insecticides in order to reduce the need for older acutely toxic insecticides and to reduce environmental loading rates.
One new class of insecticides that is gaining significant recognition in the market place is the so-called “neonicotinoid” insecticides. Insecticides of this class include nitroimino- or nitroguanidino-compounds, for example, the compounds imidacloprid, acetamiprid, and thiamethoxam that are described in U.S. Pat. Nos. 4,742,060 and 5,304,566 and EP580553A2, respectively.
Direct treatment of plant propagation materials (such as seeds) with insecticides are target applications which address the need for a reduction of environmental and worker exposure and pest resistance buildup when applied alone or in conjunction with foliar or furrow insecticide applications.
Seed treatments are used on a large variety of crops to control a large variety of pests. Seed treatments are commonly used to ensure uniform stand establishment and reducing yield loss by protecting the seedling against soil-borne insects. Systemic seed treatments may provide an alternative to traditional broadcast sprays of foliar insecticides in some instances.
Insecticide seed treatments come in a variety of formulations: dry flowables (DF), liquid flowables (LF), true liquids (TL), emulsifiable concentrates (EC), dusts (D), wettable powders (WP), suspoemulsions (SE), water-dispersible granules (WG) and others. Some are registered for use only by commercial applicators using closed application systems, others are readily available for on-farm use as dusts, slurries, water-soluble bags, or liquid ready-to-apply formulations.
Commercial seed treatment is often desirable due to the specialized equipment required to properly apply treatments or to treat large volumes of seed. An important concern of the commercial treater is equipment performance to ensure the delivery of a proper amount of active ingredient to the seed. This has become especially important with more modern insecticides that require only very small amounts of material (down to 1 g active ingredient per hundred weight of seed).
Conveniently, many seed treatment materials also are available for on-farm use. These are known as hopper-box or planter-box treatments wherein liquid or dry formulations are applied to seed as it passes through an auger from the transport bin or truck to the planter boxes. These formulations are a very convenient way to apply seed treatment onto bulk seed right before planting. Conventional dry treatments generally are formulated with talc or graphite which adheres the treatment chemical to the seed. Conventional liquid hopper-box treatments generally are made available as a fast-drying formulations. In any case, good seed coverage is required for maximum benefit from any seed treatment formulation.
However, obtaining thorough seed coverage can be difficult when attempting to treat seed. For example, dry formulations can present unacceptable worker exposure to the insecticidal active ingredient. Certain liquid formulations can become inhomogeneous on storage, such that particle size or viscosity do not remain constant. Additional problems can arise such as unacceptable drying times, material build-up in the seed treater, low seed flowability, poor seed coverage and dust-off of the insecticide from the seed prior to planting. As a result, handling is rendered difficult and the biological efficacy of the seed treatment is reduced.
There is a need in the art for alternative new liquid insecticidal seed treatment compositions that are effective for use with both commercial and on-farm seed treatment equipment.

SUMMARY

It has now been found, surprisingly, that specific filled aqueous insecticidal compositions based on the combination of a surfactant, an inorganic carrier, an antifreeze agent and an insecticide of the neonicotinoid class are storage stable, have improved flowability and have good adherence to plant propagation material with low dust-off, and have excellent performance on cold or frozen seed. The aqueous compositions of the invention have particular application in the protection of plant propagation materials, such as seeds, against insects and/or representatives of the order Acarina, but also are advantageously combined with fungicidally active compounds to control phytopathogenic fungi.
The present invention thus provides an aqueous composition suitable for applying insecticides or acaricides to plant propagation materials comprising water, an insecticidally or acaricidally effective amount of at least one nitroimino- or nitroguanidino-compound in free form or in agrochemically useful salt form and a blend of the following components, by weight:
a) 2-10% of a surface-active agent comprising a1) at least one anionic surfactant;
b) 4-20% of at least one inorganic solid carrier; and
c) 3-25% of at least one antifreeze agent.
In one embodiment, the aqueous composition further comprises a fungicidally effective amount of at least one fungicidally active compound.
The aqueous compositions are prepared by intimately mixing the components with water, optionally using a concentrated premix prepared by wet milling the solid components, until an evenly dispersed phase is achieved.
The invention also provides for plant propagation materials treated with the aqueous composition and for a method for reducing insect or acarinal infestation of plant propagation materials such as seeds and seedlings. The method comprises contacting the seeds with an aqueous insecticidal/acaricidal composition according to the invention described above.

DETAILED DESCRIPTION

The inventors have discovered that a specific combination of surfactants (a), carriers (b) and antifreeze agents (c) and a neonicotinoid insecticide when used together provide aqueous compositions that are storage stable and are suitable for use in normal seed treatment equipment, such as a slurry seed treater, direct treater, panogen treater or a mist-o-matic treater as well as on-farm hopper-box or planter-box treatments. Propagation materials treated with the aqueous compositions dry quickly, have good flowability, suitable coverage and have little or no dust-off.

Optionally, in addition to the control of insect pests, the aqueous insecticidal compositions of the invention advantageously are formulated with fungicides for seed treatment applications against diseases in the soil, which mostly occur in the early stages of plant development. For example, the compositions can be formulated to target pathogens including Pythium, Tilletia, Gerlachia, Septoria, Ustilago, Fusarium, Rhizoctonia (so-called “damping off complex”); Oomycetes such as Phytophthora, Plasmopara, Pseudoperonospora, Bremia etc. as well as against the Botrytis species, Pyrenophora, Monilinia and further representatives of the Ascomycetes, Deuteromycetes and Basidiomycetes classes.
Suitable target crops are especially potatoes, cereals, (wheat, barley, rye, oats, rice), maize, sugar beet, cotton, millet varieties such as sorghum, sun flowers, beans, peas, oil plants such as rape, canola, soybeans, cabbages, tomatoes, eggplants (aubergines), pepper and other vegetables and spices as well as ornamental shrubs and flowers.
Suitable target crops also include transgenic crop plants of the foregoing varieties. The transgenic crop plants used according to the invention are plants, or propagation material thereof, which are transformed by means of recombinant DNA technology in such a way that they are—for instance—capable of synthesizing selectively acting toxins as are known, for example, from toxin-producing invertebrates, especially of the phylum Arthropoda, as can be obtained from Bacillus thuringiensis strains; or as are known from plants, such as lectins; or in the alternative capable of expressing a herbicidal or fungicidal resistance. Examples of such toxins, or transgenic plants which are capable of synthesizing such toxins, have been disclosed, for example, in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529 and EP-A-451 878 and are incorporated by reference in the present application.
The inventive compositions are particularly suited for dressing applications on plant propagation material. The latter term embraces seeds of all kinds (fruit, tubers, grains), cuttings, cut shoots and the like. The preferred field of application is the treatment of all kinds of seeds (as specified in the target crops above), and in particular the seed treatment of canola, maize, cereals, soybeans and other legumes and crops that are susceptible.
The techniques of seed treatment application are well known to those skilled in the art, and they may be used readily in the context of the present invention. The aqueous neonicotinoid composition of the invention is applied to the seed as slurry or a soak. There also may be mentioned, e.g., film coating or encapsulation. The coating processes are well known in the art, and employ, for seeds, the techniques of film coating or encapsulation, or for the other multiplication products, the techniques of immersion. Needless to say, the method of application of the inventive compositions to the seed may be varied and the invention is intended to include any technique that is to be used.
A preferred method of applying the aqueous insecticidal composition according to the invention consists in spraying or wetting the plant propagation material with the aqueous liquid preparation, or mixing the plant material with such liquid preparation. Also, before the application, the composition of the invention may be diluted with water by simple mixing at ambient temperature in order to prepare an on-farm seed treatment formulation.
The formulation may be applied at application volumes ranging from 200 ml to 3 liters per 100 kg seed, more specifically, from 400 ml to 2 liters per 100 kg seed.
As noted above, the compositions of this invention may be formulated or mixed in the seed treater tank or combined on the seed by overcoating with other seed treating agents. The agents to be mixed with the compounds of this invention may be for the control of pests, nutrition, and the control of plant diseases.
The inventive aqueous insecticidal composition has particular application to concurrent (such as by slurry) and sequential seed treatments.
The aqueous compositions of the invention are both cold and heat stable and can be applied to seeds at temperatures ranging from −20 to 40° C.
Seeds treated with the aqueous composition of the invention have a drying time ranging from 20 to 60 seconds when being treated at room temperature.
The aqueous neonicotinoid compositions of the invention typically are distributed in a storage and shipping system comprising a container ranging in capacity from about 0.1 liter to about 2000 liters.
For example, the aqueous neonicotinoid compositions of the invention can be distributed in small containers, ranging in capacity from about 0.1 liter to about 10 liters, including the standard 2.5 gallon (9.46 liter) containers widely used in the United States, which typically take the form of jugs or flasks with a replaceable screw-cap. They are generally designed for single use and are typically not returned to the supplier when empty, instead being disposed of by the end user in accordance with local agricultural chemical container disposal guidelines, procedures, regulations or laws. Commonly, a plurality of these small containers are packaged within a single box and a plurality of such boxes are shipped on a pallet. During shipment, the small containers (usually within boxes on pallets) can be disposed in an enclosed volume such as provided by a rail boxcar or road truck, the hold of a ship or aircraft, or a modular box container adapted for transport by road, rail and water.
Larger single-use containers, ranging in capacity up to about 200 liters, for example about 50 to about 200 liters, are commonly in the form of drums, and can be shipped in an enclosed volume as described above, one or more per pallet or unpalleted.
The aqueous neonicotinoid compositions of the invention also can be distributed in a large refillable container sometimes known as a bulk or minibulk tank, which typically has an integral pump or connector for an external pump to permit transfer of liquid. Bulk or minibulk tanks having a capacity of about 200 to about 2000 liters or more are typically returned to the supplier when empty and are commonly shipped on a pallet.
A principal feature of the inventive composition is that it provides a treated seed with increased adherence which results in decreased dustiness and the subsequent elimination of related dust problems. Elimination of the dust associated with many seed treatments also eliminates the associated health hazards to those who work with treated seeds, such as processing plant employees, truck drivers, warehouse workers, and farmers.
Still another advantage of this invention is the uniform coating of-seeds with non-dusting seed treatment which will not interfere with germination and sprouting of the seed but which will protect the seed and resultant seedling against soil-borne insects and representatives of the order acarina.
