CS272898B1 - Incrustation agent with trace elements during seed dressing - Google Patents

Abstract

The solution concerns incrusting agent with microelements utilisable for seed dressing. The preparation consists of incrusting agent and of manganese-zinc salt of 1,2-ethane-bis-dithiocarbamide acid containing the following microelements: Zn, Mo, Cu, B, Co. In the mixture with ethyl alcohol it can be applied in lower outdoor temperatures.

Description

The invention relates to a seed dressing composition.

Seed dressing with various chemical preparations It is currently a necessary technological procedure for plant protection. However, the traditional application of mordant to dry conditions does not suit the large-scale agricultural conditions * The pickling progress was the so-called wet mordant, where the active ingredient (mordant) was applied to the seed surface using synthetic polymers (as film-forming components) dissolved in organic solvents. The method of pickling is characterized by a uniform distribution of the active ingredient on the seed surface. The disadvantage of applying organic solvents in pickling is their negative impact on the health of workers. When using them, it is necessary to observe a limited concentration of solvent vapors in the atmosphere on the pickling line. These drawbacks are eliminated by the water-soluble Incrustant for seed and seed dressing, according to the invention of Czechoslovak A.O. 262 480. Effect achieved by the procedure under this Czechoslovak A.O. is expanded if the incrustant comprises trace elements.

Seed dressing using the composition of the present invention not only provides seed protection from disease but also acts as a growth stimulator due to the presence of trace elements in the protective film.

The seed dressing preparation in the form of a suspension consists of polyvinyl alcohol as a film-forming agent, water as a solvent, ethoxylated fatty alcohol as a non-ionic emulsifier, food coloring as a color indicator and 5-30% by weight of the active ingredient (mordant), manganosinic acid salt 1, 2 - ethane-bis-dithiocarbamide (mancozeb), as well as 0.01-2.0% by weight of Zn and / or Mo, and / or Cu, and / or B, and / or Co.

Since pickling is also done in the winter months, it is desirable to increase the frost resistance of aqueous suspensions. For this reason, a certain amount of water in the system is replaced by technical ethyl alcohol, up to a maximum of 10% by weight, for use at temperatures below freezing.

A higher effect is achieved in that the incrusting agent contains, in addition to the pickling agent, also trace elements in ionic form, which supply the necessary substances for biological development. The incrustating agent according to the invention can be applied by conventional pickling equipment, taking into account the ecological principles of agricultural production as well as the health and economic aspects.

The examples given below illustrate the subject matter of the invention, but do not limit it in any way, but provide more advantageous advantages.

Example 1

In a 1.5 liter vessel, 950 g of water was introduced. While stirring, 50 g of polyvinyl alcohol and 3 g of ethoxylated higher fatty alcohol were added. The batch was homogenized in about 20 minutes. To the resulting solution was added, under stirring, over 30 minutes, 10 g of food dye, and 60 g of Novozer Mn-80 technical product. The whole ripening was homogenized for an additional 30 minutes. The incrustation mixture was applied to a Gustafson type turkey. Mean values of germination in relative% are given in Table no. I.
