Problems solved by technology

This disease is difficult to identify before heading, and typical symptoms appear only after heading, and it is impossible to control it at this time
Farmers in the planting area do not have enough understanding of the prevention and treatment of broomcorn smut. Once the disease occurs, they will basically not prevent and control the occurrence and prevalence of the disease, which will aggravate the occurrence of the disease. At present, there is no special control system Seed dressing
[0004] In addition, since broomcorn is mainly planted in arid and semi-arid areas, its planting techniques are relatively extensive, and fertilizers are often sprinkled into the soil before sowing, and the seeds cannot fully absorb nutrients when they grow, which affects the emergence rate.

Embodiment 1

[0018] Carry out following four groups of tests according to the millet seed dressing formulation scope of the present invention, each formulation content is as shown in table 1, is the component and the weight percent content (%) of composite seed dressing formulation in the table.

[0019] Table 1

[0020]

[0021] The active ingredients in the table are thiophanate-methyl, triadimefon, imidacloprid, methomyl, and potassium dihydrogen phosphate, the film-forming agent is sodium alginate, the preservative is sodium benzoate, the warning color is rhodamine, and the balance is kaolin. as a filler.

Embodiment 2

[0023] Four kinds of seed dressing agents obtained in Example 1 are applied to the tested variety Yumi No. 2, and an appropriate amount of water is added according to the ratio of 0.2% and 0.1% of the weight of the broomcorn millet to carry out the seed dressing treatment and piled up for 30 minutes, and planted on the inoculated broomcorn millet smut In the diseased field, the area of ​​the plot is 20m 2 (5m×4m) in the field plot, the seedling density is 50 plants / m 2 , with clear water seed dressing as the control, count the emergence of seedlings 7 days after emergence (Table 2), and count the incidence of milky stage (Table 3). The results are shown in Table 2 and Table 3, respectively.

[0024] Table 2

[0025]

[0026] By carrying out emergence rate statistics to each formula in embodiment 1, the average emergence rate of 0.2% medicine kind increases 1.3% compared with the contrast, and the average emergence rate of 0.1% medicine kind increases 4.9% compared with the...

Embodiment 3

[0031] Investigate and adopt the broomcorn millet growth agronomic character of the seed dressing agent of embodiment 1 and 2, as shown in table 4.

[0032] Table 4

[0033]

[0034] As can be seen from this table, adopt different prescription seed dressing agents, 0.2% medicine kind increases 11.1% than contrast plant height than average plant height, and 0.1% medicine kind increases 15.8% than contrast height than contrast plant height; Embodiment The average plant height of different medicinal species in the plant increased by 13.5% compared with the control plant height; the average stem diameter of 0.2% medicinal species increased by 5.8% compared with the control stem diameter, and the average stem diameter of 0.1% medicinal species increased by 5.8% compared with the control stem diameter; In the embodiment, the average stem diameter of different drug species ratios increases by 5.8% compared to the contrast stem diameter; 0.2% of the drug species increases by 5.3% c...

Abstract

A millet seed dressing agent relates to the field of agriculture, in particular to a millet seed dressing agent specially used for millet. The purpose is to provide a seed dressing formulation which can effectively prevent broomcorn smut. The broomcorn seed dressing agent includes active ingredients, the active ingredients are composed of thiophanate-methyl, triadimefon, imidacloprid, methomyl and potassium dihydrogen phosphate, each accounting for the total mass of thiophanate-methyl 12‑18%, triadimefon 1.5‑6%, imidacloprid 0.25‑1%, methomyl 0.25‑1%, and potassium dihydrogen phosphate 2‑8%. The broomcorn seed dressing agent can effectively prevent and cure broomcorn smut, and at the same time provide nutrients in the germination stage of the broomcorn, promote the uniformity and robustness of the broomcorn seedlings, improve the agronomic traits of the broomcorn broomcorn, and increase the yield of the broomcorn broomcorn.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a seed dressing agent specially used for broomcorn millet. Background technique [0002] Seed dressing agent is a kind of pesticide assembly that can be mixed with seeds and attached or soaked into seeds, and can prevent and control pests and diseases. The germination and growth of crops is non-toxic, and the formed drug film has water permeability and air permeability, and does not affect the life and respiration of seeds. The seed dressing agent has the characteristics of high efficiency, economy, safety, long residual effect and multi-function. [0003] Broomstick smut is the main disease that affects the growth and yield of broomcorn millet, and the pathogen is Smut smut ( Sphacelotheca destruen (Schlecht.) Stevens et A. G. Johns) and Ustilago militaris ( Sphacelotheca manchurica (Ito) Wong) is a systemic infectious disease, and the onset usually results in failure of the whole ...
