Description

The invention relates to agriculture and can be used to protect safflower plants from root rot and as a way to increase its productivity in the conditions of the Lower Volga region.

At the present stage of development of technologies for the cultivation of safflower dyeing in arid regions, measures to protect it from pests and diseases become urgent issues. In connection with the growth of its sown area, due to the demand for its oilseeds for the production of oils, the rotation of crops in crop rotation is often disrupted, resulting in an aggravated phytosanitary situation in its crops.

A known method of soil preparation, seed treatment and sowing safflower, and it additionally performs pre-sowing treatment of seeds with a mixture, which consists of Force insecticide with a flow rate of 1.6 l / t, growth regulator Vermistim D with a flow rate of 6.0 l / t (UA patent 82598).

The use of this method is expensive and does not provide an effective suppression of seed infection and a decrease in the spread of root rot, as well as the activation of production processes of plants.

The well-known "Method of cultivating safflower in a sharply continental climate", where the control of safflower diseases is carried out by fine-dispersed spraying of a solution of natural bischofite mineral at a rate of 400-600 l / ha at an ambient temperature of no higher than + 10-15 ° C (RF patent No. 2232491, AO1B 79/02, 2004).

The disadvantages of this method include an increase in the cost of the final product, because produce winter sowing of safflower with a high seeding rate and additional tillage.

The analysis of the known solutions by the applicant on patent and scientific sources of information made it possible to establish that the claimed invention meets the requirement of “novelty” under current law.

The composition of the tank mixture includes the following drugs:

Vincite is a highly effective liquid disinfectant for cereal seeds. Protects seedlings and young plants from soil and seed infections. Vincite is rapidly absorbed through the shell of the seed, entering the embryo, and then into the conducting system of the developing plant and ensures the death of pathogen cells.

Fertigrain Start is an organic biostimulator, in addition to amino acids, it includes an extract from seaweed containing phytohormones auxins (accelerate seed germination), cytokinins (necessary for cell division, growth and differentiation), as well as polysaccharides - an additional source of available energy. Amino acids (total) - 9.0%, free amino acids L - 6.5%, nitrogen - 3.0%, organic substances (total) - 30%, seaweed extract - 4.0%. pH is 6.6.

Tank mixture for dressing safflower seeds: Vincit (1.5 l / t), Fertigrain Start (0.5 l / t), the rest is water. For processing safflower seeds, the flow rate of the working solution is 10 l / t.

Due to the synergistic effect with the gradual mixing of drugs, the pesticide consumption rate is reduced by 30%.

The invention allows to increase safflower productivity and the quality of the products obtained, improve the phytosanitary situation in crops and reduce the pesticidal load on agrocenoses.

The data (table) indicate the high efficiency of the proposed method, the yield growth of safflower reaches 0.5 t / ha. Profit per 1 ha amounted to 12,190.0 thousand rubles.

A known method of cultivating winter safflower (Patent KZ 26195, АВВ 79/02, 10/31/2011), where it is proposed to treat safflower crops with insecticides in the years of epiphytosis.

From the selected sources during the patent search, we can conclude that almost negligible value is given to the protective measures of plants. Therefore, the proposed method of protecting safflower from root rot will have patent purity and is relevant for regional producers.

The development of diseases is facilitated by the cultivation of non-adapted varieties, violations of agricultural technology and especially the rules of seed production, unbalanced nutrition, and often starvation of plants.

When growing crops, it becomes necessary to use protectants and growth stimulants. The use of combinations of small doses of several drugs gives the same biological effectiveness and duration of action as treatment with one more toxic drug at a higher dose. Microbiological preparations reduce the negative impact of pesticidal treatment of seeds and crops, increase seed germination, the intensity of plant development and their productivity.

The basis of the present invention is the task of developing an innovative method of presowing treatment of safflower seeds, which provides increased seed germination, their adaptation to stress factors, suppression of the development of infectious diseases, increased product stability while reducing production costs.

A protective and growth-promoting effect is achieved during pre-sowing treatment of seeds with a tank mixture, which includes a chemical disinfectant with an underestimated dosage + a growth biostimulator.

The invention relates to a method for protecting safflower plants from root rot, as well as stimulating the growth and development of plants, during which seed treatment is treated with a tank mixture: Vincit 1.5 l / t + Fertigrain Start 0.5 l / t

Claims (1)

A method of protecting safflower plants from root rot in the conditions of the Lower Volga region, which consists in using a tank mixture for presowing treatment of seeds, characterized in that when dressing seeds in an aqueous working solution in the amount of 10 l / t, Vincit enters - 1.5 l / t, Fertigrain Start -0.5 l / t.
