Treatment of plant propagation material with pesticide compositions allows protection from soil pests during susceptible stages in plant growth. In addition, permeable seed treatment can provide an alternative to traditional foliar pesticide application. However, after this treatment, the treated plant propagation material is handled and transported for packaging and storage, which often causes the treated plant propagation material to come into contact with each other to drop off the chemicals attached to the plant propagation material. The chemicals released are often in the form of airborne particles, for example of pesticides and other substances, derived from treatment compositions which, for example, form solid particles upon drying of the seed. This results in the loss of the insecticidal effect of the treated plant propagation material and can threaten the health of workers doing such treatments through inhalation and sensitization of airborne particles, eg eye irritation. In addition, the treatment of plant propagation materials is often carried out with slurry compositions comprising a mixture of pesticide compositions, which leads to immiscible difficulties. That is, it causes aggregation and heterogeneity between different pesticide compositions. Pesticide compositions with low pH are known to be particularly difficult to formulate miscible slurries.

Usage

The composition of the present invention can be used in a conventional way to control pests from plants.

The pesticide compositions according to the first and second aspects are used for the treatment of plant propagation materials, which have a level of protection against freezing during germination and growth.

The term “plant propagation material” is understood to refer to all the reproductive parts of the plant, for example seeds, and to reproduce the latter and nutritious plant materials, such as cutting branches and tubers (eg potatoes). Can be used for For example, seeds (in strict sense), roots, fruits, tubers, bulbs, rhizomes, and parts of plants can be mentioned. Mention may also be made of germinated plants and seedlings which must be transplanted after germination or after emergence from the soil.

Optionally, in addition to controlling insect pests, the compositions of the present invention are advantageously formulated with fungicides for seed treatment against soil diseases most often occurring in the early stages of plant growth. For example, the composition may be Pythium, Tilletia, Gerlachia, Septoria, Ustilago, Fusarium, Rhizoctonia, Referred to as "damping off complex"; Oomycetes, such as Phytophthora, Plasmopara, Pseudoperonospora, Bremia, etc., as well as Botrytis species , Pyrenophora, Monilinia and additional representative Ascomycetes, Deuteromycetes and Basidiomycetes species Can be.

Suitable purpose crops are in particular potatoes, cereals (wheat, barley, rye, oats), rice, corn, sugar beets, cotton, millet varieties, sugar cane, tobacco, sunflower, soybeans, peas, oil plants (flat, canola), soybeans, Cabbage, tomatoes, aubergine, pepper and other plants, and spices, as well as ornamental shrubs and flowers.

Suitable target crops also include transgenic crops of the various crops. The transgenic crops used according to the invention are plants or their propagation material, which are transformed via recombinant DNA techniques, which are known, for example, from toxin-producing invertebrates of the phylum Arthropoda , for example. Selectively acting toxins (which may be obtained from Bacillus thuringiensis strains); Or optionally acting toxins known from plants, for example lectins; Or alternatives capable of expressing herbicides or bactericidal resistance can be synthesized. Examples of such toxins or transgenic plants capable of synthesizing such toxins are, for example, EP-AO 374 753, WO 93/07278, WO 95/34656, EP-AO 427 529 and EP-A-451 878 And incorporated herein by reference.

The composition is suitable for dressing of plant propagation material. The latter term includes all kinds of seeds (fruit, tubers, grains), chopped branches, chopped shoots, and the like. Preferred fields of application are the treatment of all kinds of seeds (specified in the crop of interest above), in particular the treatment of canola, corn, grains, cotton, tomatoes, tobacco, soybeans, other legumes, and other vegetables and susceptible crops. And particularly preferably seed treatment of cotton, corn and soybean crops.

As noted above, the compositions of the present invention may be formulated or mixed in a seed treatment tank or combined with overcoated seeds with other pellet materials and / or seed treatment agents. Such seed treatment agents mixed with the compounds of the invention are for pest control, nutrition and plant disease control.

The composition is specifically applied to simultaneous and subsequent seed treatments. Seeds treated with the compositions of the invention generally have a drying time in the range of 20 to 60 seconds, at which time they are treated at room temperature. Generally, for vegetable seeds, spray drying techniques are used.

Preferred methods of applying the composition according to the invention consist of spraying or wetting the plant propagation material into a liquid formulation or mixing the plant propagation material with such a liquid formulation. In addition, prior to application, the composition of the present invention may be diluted with simple mixing at room temperature to produce seed treatment formulations on a farm.

The formulations can be applied to inexpensive crops, for example cereals, in application volumes in the range of 200 ml to 3 l per 100 kg of seeds, more particularly 400 ml to 2 l per 100 kg of seeds. For vegetable crop seeds, higher amounts apply.

An advantageous feature of the composition is that it increases the adhesion of particles, especially airborne particles, to seeds, thereby reducing dust and subsequently solving dust related problems. The removal of dust associated with many seed treatments also eliminates dust-related health hazards for those who work with treated seeds, such as processing plant workers, truck drivers, warehouse workers and farmers. The compositions of the present invention also have satisfactory flowability and individuality of the propagation material (ie, the propagation material is easily handled and does not stick together).

Another advantage of the present invention is the uniform coating of seeds with non-dust seed treatment, which can protect the seeds and the seedlings obtained from pests, in particular soil pests, without disturbing the germination and growth of the seeds.

When the composition according to the invention is applied directly to the seed, seed fragments or exposed roots initially by dipping for crop protection, there are several distinct advantages from both economic and environmental standpoints. Preferably, by planting or seeding the seeds, seed fragments or exposed roots with pesticides, for example nematicides, in the case of abamectin, the pesticides are concentrated at the site of pests, eg nematode attack, thus Less active ingredient per acre is required compared to conventional soil spreading. This is not only more economical for pest control but also minimizes environmental disturbances and any undesired adverse effects.

As used herein, certain aspects of the invention are independent of one another unless otherwise indicated.

The following examples are intended to illustrate but not limit the invention.

Formulation Examples A, B, 1, and 2 are formulated with surfactant (s), thickeners, polymers (if any), suspension aids (if any), antifoams, preservatives and cryoprotectants, when a homogeneous phase is achieved It was prepared by mixing. Subsequently, abamectin was added and mixed. The resulting mixture was then wet milled through a so-called bead mill (Dyno, Drais, Premier for instance). The grinding parameters are determined by the way in which the average molecular size of the powder premix obtained is present in the specification (usually the median particle size average is mostly 2.0 μm). Finally, a buffer (if any) and a minimum amount of water were added and the final product was mixed for at least 30 minutes. Table 1 shows its composition details, omitting antifoams, preservatives, thickeners and wetting agents.

Miscibility Research

Each pesticidal formulation examples A, B, 1 and 2 are mixed with a pesticidal formulation (X) having a pH of about 5.5 to form a slurry composition and its compatibility is observed. Formulation Examples 1 and 2 have been found to provide better miscibility (ie, less aggregation and better miscibility) than Formulation Examples A and B.

Seed treatment research

The rate of treatment of the composition with respect to the seed is the rate at which the equivalent of a solid material (eg active ingredient and colorant) is applied to the seed.

Abamectin free composition:

Pesticidal formulation (X); A composition (Y) comprising calcium carbonate, a fungicidal pesticide formulation and a colorant; Polymer (Z); And a slurry composition comprising water was treated to cotton seeds with a Heg seed treatment apparatus.

Polymer free composition:

Each pesticide formulation Examples A, B, 1 and 2 are mixed with pesticidal formulation (X) and water and the heg seeds in cotton seeds pretreated with a composition (Y) comprising calcium carbonate, fungicidal pesticide formulation and colorant The treatment device was used.

Dust removal measurement

The amount of 'dust' released from the treated seeds is measured by placing the treated seeds in a ridge shaped plastic drum, where the drum is a rotating stimulator for handling and transporting the seeds. The precise airflow control system provides a constant airflow that carries airborne particles through the coarse filter separator into the filter. The amount of dust was measured by weighing the filter. Data for the 'dust removal' measurements are listed in Table 2.

The data indicate that the seed treated with the composition comprising the formulated surfactant compound (Formulations 1 and 2) provides less airborne particles, i.e., better dust removal compared to the compositions comprising Formulations A and B. . Also surprisingly, the amount of dust from the composition comprising Formulations 1 and 2 is less than the amount of dust of the seed treated with a composition that does not contain abamectin (ie, a composition comprising less solids content in the seed).
