Description

one

The invention relates to methods for controlling phytogenic fungi and their strife that cause damage to seeds, as well as methods for protecting seeds from such fungi with the help of a protravitel.

The use of 1,4-dimethoxy-3,6 dichlorobenzene for seed etching is known.

In order to expand the range of active and low-toxic seed disinfectants, it is proposed to use 5-acetyl-8-hydroxynquinoline sulfate.

The form of the drug is typical: solutions, suspensions, dusts, powders, obtained by adding to the current top of solvents, emulsifiers, disnergators, fillers, nrnnpateley.

The proposed dressing agent can be used to protect the seeds of various plants: wheat, rye, barley, oats, corn, rice, hlonka, sugar beet, and others, from phytoyathogenic fungi such as: smut fungi (Tilletia tritici, Ustilago triiici, Ustila, 9; o nudae, Uslilago avenae, Ustilago zeac), gray mold (Fusarium nivale), fragility of ears (Pythium spp.) n. etc. The amount of protravitel is from 0.01 to 10 g (preferably 0.1 to 3.0 g) of the current substances per 1 kg of seed.

Example 1. Artificially infected

with spores of smut (Tilletia tritici) of winter wheat, variety Probus (3 g of dry material of spores per 1 kg of seed) was subjected to dry and diluted according to luv; number 1; rotravntel. Dry protraoitel had the following composition, weight. %: paraffin oil, 11e1 1 stral H 10 10 3-an, etil-8-hydroxyquinol 1P sulfate 20 ng.g 79.

In the blank run, a preparation consisting of 1 wt. including paraffin oil and 79 hz. talc without a start, put it on the unclean wheat seeds in the following quantities; g // Cc seme) :: A 12, B 6, C 1,2.

Control experiments 1 and 2 are different from idle experience in that the countries of the world infecting 1x seeds, as indicated above.

Infected and treated Nshezzy seeds were sown in October at the experimental field in plots of 1 (for 1 m – 20 gems: n - 500 grain grains). Each control product accounted for 2 sites. For snredoedinoy activity

At the beginning of b: .-; whether ripe ears were cut from individual sections. Then, healthy and non-fungal fungal spike were counted, recalculated and weighted151. From these data, the percentage of damage was determined. Received) 1st result: are shown in Table. one.

Table 1

From the data in the table it can be seen that the proposed 5-acetnl-8-hydroxyquinoline sulfate is not inferior to the efficiency of methoxyethyl mercuric silicate and 1,4-dimethoxy-3,6-dichlorobenzene, known as seed removers.

Example 2. The effectiveness of the treatment with 5-acetal-8-hydroxyquinoline sulfate against Rhizoctonia solani on potato tubers was tested as follows.

The tubers, on which there were sclerotia of the fungus Rhizoctonia solani, were loaded for 60 seconds into solutions with different concentrations of the active principle, dried and then planted 4 to 4 times on 12.5 m land plots. Cropped plants 20-25 cm high were examined for the disease. When harvesting, the total weight of the potato tubers of each piece of land and the individual tubers were evaluated for sclerocyte infection.

The results are shown in table 2.
