Description

The invention relates to agriculture, preferably to a technology for protecting sunflower plants from diseases.

A known method of combating fungal diseases of cereals, including treating plants with SILK, in which the plants are treated in the tillering phase at a dose of 4.0-5.0 g / ha of the active substance (RU Patent No. 2147400 C1. IPC ⁷ A01N 37/08, A01N 61/00, A01N 365/00. A method of combating fungal diseases of grain crops / V. M. Chekunov, M. I. Zazimko, L. D. Zhalieva and others (RU). - Application No. 98101941 / 04; claimed 04.02.1998; publ. 20.04.2000).

The disadvantages of the described method, despite the specified technical result - increasing the efficiency of the fight against diseases of grain crops, increasing yields, reducing the spread of leaf diseases and ears of crops, as well as rot, include a limited range of crops for the use of the claimed drug.

It is also known a tool that is close to the claimed object in its essence and the achieved technical result, used for foliar feeding of grain crops, is a natural mineral bischofite with a concentration of 4-6%. The drug is used during tillering-going into the tube at a consumption rate of 400-600 l / ha (RU, patent No. 2120754 C1. IPC ⁶ A01N 59/06, C05D 5/00. Means for foliar feeding of grain crops / T.A. Koroleva , M.N. Belitskaya, V.N. Maksyuta et al. (RU) .- Application No. 97107368/13; claimed on 05/06/1997; publ. 10/27/1998).

The above tool is used for foliar processing of oilseeds during their intensive growth with a 5-7% aqueous solution of bischofite mineral. This allows you to increase the yield of oilseeds and improve the quality of the crop (RU, patent No. 2134252. C1. IPC ⁶ C05D 9/02, A01C 21/00, A01N 59/08. Means for foliar processing of oilseeds / G. G. Rusakova, M .N. Belitskaya, T.A. Koroleva et al. (RU) .- Application No. 97120819/25; claimed 11/12/1997; publ. 10.08.1999).

The disadvantages of the presented growth stimulator - the natural mineral bischofite with foliar oilseed top dressing - include weak growth-regulating activity due to the structural features of baskets, leaves and stalks of sunflower.

A close remedy on the basis of the selection of components for bischofite is a plant dressing agent, including an aqueous solution of the natural mineral bischofite, which additionally contains organic fertilizer in the following ratio of components, wt.%: Bischofite - 0.9-2.2, organic fertilizer - 2, 0-3.0, water - the rest, or instead of organic fertilizer, a growth stimulator is added in the following ratio of components, wt.%: Bischofite - 0.9-2.2, growth regulator - 0.01-0.06, water - the rest ( RU, published application for invention No. 2002123483 A. IPC ⁷ C0 5D 5/00, A01N 59/06. Means for plant nutrition (options) / MN Belitskaya. - Stated September 2, 2002; publ. March 10, 2004).

The effectiveness of the above compositions and doses depends not only on the drugs used, but, which is no less important, on the phase of plant development and the time of application of the drug.

A close remedy for the vegetative treatment of sunflower plants is a composition consisting of an aqueous solution of the natural mineral bischofite, which additionally contains a growth stimulant immunocytophyte or immunocytophyte with a strong in the following ratio of components, wt.%: Bischofite - 3.0-5.0, immunocytophyte - 0.002 , water - the rest; or bischofite - 3.0-5.0, immunocytophyte - 0.002, silk - 0.015, water - the rest (RU, patent No. 2228118 C1. IPC A1N 65/00. Means for the vegetative treatment of sunflower plants (options) / A.A. Astakhov, A.V. Lomtev, AMSaldaev (RU) - Application No. 2007107781/15; filed March 1, 2007; published on February 4, 2008).

The disadvantages of the described tool, despite the technical result indicated, is an increase in seed yield while improving seed quality and at the same time improving the phytosanitary situation in crops, the fact that plant growth stimulators cannot eliminate the deficiency of important nutrients, especially microelements, of which the first minimum for sunflower there is boron and zinc.

The objective of the invention is to stimulate growth and immune functions to a complex of plant diseases in the period of 3-5 pairs of true leaves - the beginning of the phase of formation of the basket in sunflower plants.

EFFECT: increased yield of sunflower seeds while increasing oil content of seeds, reducing oil acidity and the spread of diseases due to the use of highly effective compositions for vegetative treatment of plants with Proboron at the rate of 0.1% in a mixture with a solution of brine of the natural environmentally friendly mineral bischofite at the rate of 2, 0-6.0%.

The technical result is achieved by the fact that for a single or double treatment of sunflower plants, a tank mixture of the following composition is used, wt.%:

Parting 0.1 Bischofite mineral brine with a density of 1.30-1.32 t / m ³ 2.0-6.0 Water Rest

The drug Proboron is a boron-based liquid fertilizer made from seaweed containing the trace element B - 14%, N - 5%, organic substances - 15%. Products made from seaweed extract contain non-nitrogen organic substances, vitamins, amino acids and trace elements. In particular, they contain algal polysaccharide, algal acid and many unsaturated fatty acids extracted from algae, plant growth regulators: auxin, cytokinin, gibberellin, abscisic acid. These elements have good biological activity, contribute to the stimulation of vague internal factors of vital activity and regulate the balance of endogenous hormones.

The effect of the use of the drug:

- improves the movement of growth substances and ascorbic acid from leaves to the fruiting organs;

- plays a significant role in the process of fertilization;

- promotes better germination of pollen, eliminates the falling of ovaries and enhances the development of reproductive organs;

- improving boron nutrition leads to an increase in sugar content of sugar beets, an increase in the content of vitamin C and sugars in fruit crops, tomatoes, etc .;

- increases productivity and product quality.

Plant treatment is carried out at the rate of 250-300 liters of the composite mixture per hectare. With a single treatment of vegetative sunflower plants, they are sprayed in the phase of the beginning of the formation of the basket, and with double treatment: the first in the phase of 3-5 pairs of real sunflower leaves, and the second in the phase of the beginning of the formation of the basket.

The drug Proboron in the required amount is dissolved in a small amount of water. Then the components in aqueous solutions are mixed and thoroughly mixed.

The effectiveness of vegetative treatments of sunflower plants is presented in tables 1-4.

Vegetative treatment of plants with tank mixtures of Proboron with a solution of bischofite brine increases the productivity of sunflower while increasing oil content and reducing acidity of the oil while improving the phytosanitary situation in crops.
