preparation example Construction

[0033] Such as figure 1 Shown, the preparation method of the compound fungicide of the embodiment of the present invention comprises the following steps:

[0034] S101: Put 2.7g of carbendazim and 0.3g of tebuconazole into a mixing tank, add 10.20-10.70g of emulsifier Op10 and stir to dissolve, then let stand and mix evenly;

[0035] S102: Use a small beaker to weigh 0.002g of gibberellin, add 4.3±0.5g of alcohol to dissolve it, put it into a mixing tank and stir evenly, and fill up with 100g of latex paint.

[0036] The application effect of the present invention is further described by following tests:

[0037] 1. Materials and methods

[0038] 1 test material

[0039] 1.1 bacterial strain, test pathogenic bacterium Valsa ceratosperma is separated and preserved by the laboratory;

[0040] 1.1.1 Chemical agents, triazole fungicide 97% tebuconazole original drug; benzimidazole fungicide 98% carbendazim original drug;

[0041] 2 methods:

[0042] Effect of Experiment 1 on...

Embodiment 1

[0085] Embodiment 1 liniment (ointment)

[0086] Carbendazim: 2.7%, Tebuconazole: 0.3%, Emulsifier Op10: 10.20%~10.70%, Gibberellin GA: 0.002%, Alcohol (4.3±0.5)% latex paint to 100g

[0087] First, accurately weigh the ingredients of the above formula, put carbendazim and tebuconazole into a mixing tank, add an appropriate amount of emulsifier Op10 to fully stir and dissolve, then accurately weigh gibberellin in a small beaker, add an appropriate amount of alcohol to dissolve and put Put it into a mixing tank and stir evenly, and fill up the latex paint to 100g.

Embodiment 2

[0088] Embodiment 2 smear (ointment)

[0089] Carbendazim: 4.5%, Tebuconazole: 0.5%, Emulsifier Op10: 15.94%-16.50%, Gibberellin GA: 0.002%, Alcohol (4.3±0.5)% latex paint to 100g. See Example 1 for the preparation process.

Abstract

The invention discloses a compound fungicide and a preparation method thereof. The compound fungicide is composed of active ingredients, fillers and auxiliary agents, wherein the active ingredients are composed of triazole fungicides tebuconazole, benzimidazole fungicides and more. Bacillus composition. It can effectively control fungal diseases of branches such as apple bark rot fungus and apple ring rot fungus. The present invention has a significant synergistic effect on preventing and treating fungal diseases of apple tree rot, and the eradication effect of the X% DW ointment reaches 100% within 120 days, which is significantly higher than that of a single preparation; the compound preparation has good quick-acting and long-lasting effects, and the action mechanism There are many sites, which can effectively delay the occurrence and development of drug resistance of pathogenic bacteria. In addition, the preparation process of the present invention is simple, low in cost, remarkable in economic benefit, broad in disease prevention spectrum, and high in biological safety.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a compound fungicide and a preparation method thereof. Background technique [0002] Apple tree rot is caused by the genus Valsa ceratosperma, and it is a widely distributed and serious disease on apples. Since the first discovery of apple tree rot in my country, there have been four major epidemics in China (Zeng Shimai. Macrophytopathology. Beijing: China Agricultural Press, 2005). In 2007, the national apple industry technology system was established, which created conditions for the investigation and prevention and control of apple diseases and insect pests nationwide. The survey results in 2008 showed that the average incidence rate of apple rot disease in major apple producing provinces in the country was 52.7%. It can be seen that the occurrence of rot disease is very common and serious. [0003] Chemical control is one of the effective measures t...
