Wheat is one of the main grain crops planted in China. The current bactericide varieties used for preventing and treating the field diseases of main grain crops such as wheat and the like have the defects of large using amount and strong drift; and the long-term single use of the bactericide can cause the increase of the drug resistance of various field diseases, and secondly, the use cost of the existing bactericide is high. Therefore, the development of a high-efficiency, low-toxicity, low-residue and safe field sterilization pesticide suitable for main grain crops such as wheat is urgently needed, and the mixing of different pesticide varieties is just one of common methods for preventing and controlling agricultural diseases and insect pests.
Copper formulations are one of the oldest agricultural germicide formulations in the world. The oxine-copper is a quinoline protective low-toxicity bactericide, is a novel organic chelate, has the advantages of broad spectrum, high efficiency, low residue, safe use and the like, has good prevention and treatment effects on fungus and bacterial diseases, forms a tight protective medicine film on the surface of a plant after being sprayed, has strong affinity with the plant and resists rain wash; the medicine film slowly releases bactericidal copper ions, effectively inhibits the germination and invasion of germs, thereby achieving the purpose of preventing and treating diseases.
The chemical structural formula is as follows:
the molecular formula is as follows: c18H12CuN2O2Relative molecular weight: 351.85
The chlorothalonil is a non-systemic broad-spectrum protective bactericide, and the action mechanism is that the chlorothalonil can act with glyceraldehyde triphosphate dehydrogenase in fungal cells and is combined with protein containing cysteine in the enzyme, so that the activity of the enzyme is damaged, and the metabolism of the fungal cells is damaged to lose vitality. Its main function is to prevent and cure the plant from being damaged by fungus, and it has good adhesion on the surface of plant, so that it has long effective period. The chemical structural formula is as follows:
the molecular formula is as follows: c8N2Cl4Relative molecular weight: 265.91
The two active ingredients in the composition have different action mechanisms, and a large number of experimental formula screening studies show that the existing binary compound sterilization composition taking oxine-copper and chlorothalonil as active ingredients has good synergistic effect on leaf blight, leaf rust, stripe rust and leaf spot of wheat, can well delay the generation of disease resistance, reduce the medication cost and improve the actual prevention effect through field efficacy.

Field test example 2
The purpose is to further determine the influence of the ratio of the oxine-copper to the chlorothalonil in the oxine-copper and chlorothalonil suspension on the control effect.
The control effect of the bactericidal composition of examples 7-12 on diseases is tested in wheat planting areas, the specific steps and test methods are the same as those in the field test example 1, and other basic conditions of each planting area are guaranteed to be the same as far as possible.
The specific results of field test example 2 are shown in table 2:
as shown in Table 2, the control effects of the embodiments 9 to 10 are the best, that is, the ratio of the two active ingredients in the oxine-copper and chlorothalonil compound bactericidal composition is 1: 3 or 3: the compound has the best drug effect when 1.
