The method of processing plants and used in the composition of plant protection

 

The group of inventions is intended for use in crop production and agricultural chemistry. The proposed composition for the protection of plants and the method of processing plants in the production of crop products, consisting in processing plants specified composition containing the composition of the target additives preparation obtained by sequential extraction of biomass micromycete Mortierella gracilis polar extractant in the supercritical state, water, alkali, water, acid, water, alkali and water with subsequent uniting of the solid residue from the first extract. When plants are treated with this composition in an amount of 0.1-20 mg/ha planting or 0.5-10000 mg/t of seed in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids. The invention reduces the accumulation of toxic substances in crops and soil, their migration, and stress effects of toxic substances on crops. 2 C. p. F.-ly, 3 tables.

Group of inventions relates to the technology of crop production.

A method of processing plants in crop production, providing education is the following sorbents, adhesives, binders, wetting, fillers, etc. (Chemical plant protection. Edited Gruzdeva, C. - M.: Agropromizdat, 1987, S. 27-32).

The disadvantage of this method is the accumulation of toxic substances in agricultural plants and in the soil, the migration of toxic substances, rendering a negative impact on crops.

Known compositions for protecting plants containing at least one toxic substance and targeted supplements, including absorbents, adhesives, binders, wetting, fillers and so on (ibid.).

These compositions have the same drawbacks as the above-described method of using them.

The technical result of the group of inventions is the reduction of stress on crops, accumulation of toxic substances in crops and soil, their migration.

This result is achieved in that in the method of processing plants in crop production, providing the plant treatment composition containing at least one toxic substance and the target additives according to the invention, in the composition of the target additives used by preparation in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue in an amount of 0.1-20 mg/ha planting or 0.5-10000 mg/t of seed in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids.

The same result is achieved in that the composition for protecting plants containing at least one toxic substance and the target additives according to the invention, the composition contains special additives in an effective amount of the drug obtained by sequential extraction of biomass micromycete Mortierella gracilis nonpolar solvent in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue.

The method is implemented as follows.

Used in the way the composition is prepared by injection, obtained by sequential extraction of biomass micromycete Mortierella gracilis nonpolar solvent, for example carbon dioxide, nitrogen, nitrous oxide, aliphatic hydrocarbons, inert gases in the supercritical state, water, alkali, water, acid, water, alkali and water shields plants or other compositions, containing one or more toxic substances, biocides, together with other targeted supplements, such as absorbents, adhesives, binders, wetting, fillers, so that the total content in the composition of chitosan, arachidonic and eicosapentaenoic acids corresponded to the rate of 0.1-20 mg/ha planting of vegetative plants or 0.5-10000 mg/t of seed, or by the making of a binary mixture at the same ratio of components, which are mixed directly in the process of applying.

The prepared composition is applicable for treatment of seed and/or vegetative plants in liquid or solid phase state, depending on the form it uses toxic substances and the commodity form of the composition. Statistically significant decreasing inhibitory action of the composition on the development of agricultural plants, the decrease in the accumulation of toxic substances in plants and soil, their migration.

Example 1 the Crickets prepared by mixing toxic substances tetramethylthiuramdisuphide in the amount of 0.8 kg/t of product from biomass micromycete Mortierella gracilis in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids is m table 1 [1]. The prepared composition is treated corn seeds. For comparison, corn seeds treated with the same composition without drug from biomass [2], a similar composition without toxic substances [3]. The obtained results are compared with untreated seeds of corn are shown in relative values in table 1, where columns in the order the data by groups of seeds after different treatment.

Example 2 Fungicidal composition is prepared by mixing toxic substances propiconazole in the number 0,125 kg/ha, preparation of biomass micromycete Mortierella gracilis in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids in an amount of 10 mg/ha and water in the amount of 300 l/ha [1]. The prepared composition is treated winter wheat in early stage of elongation. For comparison, wheat treated with the same composition without drug from biomass [2], a similar composition without toxic substances [3]. The data obtained compared to the untreated control are shown in relative values in table 2, where the columns in the order the data by groups of treated plants.

Example 3 Gerbil is attachment 1:1:1 in the amount of 0.9 kg/ha, preparation of biomass micromycete Mortierella gracilis in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids in amounts of 20 mg/ha and water in the amount of 300 l/ha Obtained by composing process the beets in phase 2 pairs of true leaves. Compared to standard treated the same composition without drug from biomass, yield increased by 29%, the rate of decomposition of toxic substances in plants has increased 2.4 times, on the grounds 1.9 times.

Example 4 Insecticidal composition is prepared by mixing toxic substances chlorophos in the amount of 0.5 kg/ha, preparation of biomass micromycete Mortierella gracilis in terms of the total content of chitosan, arachidonic and eicosapentaenoic acids in an amount of 0.1 mg/ha and water in the amount of 300 l/ha Obtained by composing process peas in the beginning stage of vegetation. For comparison, the peas are treated in a similar composition without drug from biomass. Compared with the standard rate of decay of toxic substances increased in plants for 6 days on the ground for 4 days, the grain yield increased by 30%.

Example 5 Composition having fungicidal and nematicidal activity, are prepared by mixing toxic substances thiabendazole at stake is fidanova and eicosapentaenoic acid 10 g/t, the foaming agent, surfactant and water in the amount of 7 l/t [1]. The obtained composition is treated with seed potatoes. Its the same for the comparison process similar composition without drug from biomass [2], a similar composition without toxic substances [3]. The data obtained compared to the untreated control are shown in relative values in table 3, where the columns in the order listed information about potatoes, past various processing.

Thus, the proposed group of inventions can reduce depressant effects of toxic substances on crops, as evidenced by increasing their productivity, reduce accumulation of toxic substances in plants and on the soil and, consequently, reduce their migration.
