Problems solved by technology

These two diseases alone will cause a 5-30% reduction in wheat production every year, causing huge losses to China's grain production
Not only that, at present, powdery mildew on flowers, fruit trees, vegetables, medicinal materials and other crops is gradually aggravating. In recent years, although there are many varieties of agents used for powdery mildew or rust, they have been used all year round, resulting in serious resistance. New fungicides with high efficiency, low toxicity, environmental protection and no cross-resistance and their compositions are one of the ways to solve this problem
At present, there is no report on the compounding of penflufen and carvacrol to control powdery mildew or rust

Embodiment 1

[0021] Example 1: 5% Penflufen·Carvacrol EC formula and production process

[0022] Formula: Penflufen 0.5%, carvacrol 4.5%, ethanol 30%, calcium dodecylbenzenesulfonate 3%, Nongru 1601# 7%, Nongru 6023%, and the rest is ethyl acetate.

[0023] Production process: Put the above formula into a stirred reactor according to the proportion. The total processed materials are 1000kg, the stirring is turned on, the stirring speed is 80r / min, and the material is discharged after stirring for 20 minutes. After passing the test, it is divided into 5% penpyridine·· Carvacrol EC.

Embodiment 2

[0024] Example 2: Formula and production process of 10% penflufen·carvacrol wettable powder

[0025] Formula: Penflufen 2%, carvacrol 8%, open powder 5%, sodium lignosulfonate 5%, sodium lauryl sulfate 1.5%, white carbon black 10%, and the rest is kaolin.

[0026] Production process: Put the above formula into the non-gravity stirring tank according to the proportion, the total processing material is 1000kg, turn on the stirring, after 15 minutes of stirring, enter the airflow pulverization, after completion, enter the non-gravity stirring tank again, and discharge after 15 minutes of mixing. After passing the 325-mesh sieve, sub-packaging after passing the content test to obtain 10% penflufen·carvacrol wettable powder.

Embodiment 3

[0027] Example 3: Formula and production process of 30% penflufen·carvacrol wettable powder

[0028] Formula: Penflufen 15%, carvacrol 15%, open powder 7%, sodium lignosulfonate 7%, sodium lauryl sulfate 2%, silica 15%, and the rest is kaolin.

[0029] Production process: Put the above formula into a stirred reactor in proportion, the total processed material is 1000kg, turn on the stirring, the stirring speed is 80r / min, after stirring for 20 minutes, the material is discharged, and after the test is qualified, it is divided into 30% penpyridine· Carvacrol wettable powder.

Abstract

The invention discloses a fungicidal composition containing penflufen and carvacrol and use of the fungicidal composition, wherein the mass ratio of penflufen to carvacrol is (1-10) to (1-10), the mass of the effective constituents accounts for 5%-80% of the total mass of the fungicidal composition. The fungicidal composition can be processed into various dosage forms including emulsion oil, microemulsion, a suspending agent, wettable powder or a water dispersible granule. The fungicidal composition containing penflufen and carvacrol disclosed by the invention has good prevention and treatment effects on common powdery mildew or rust diseases of wheat, fruit trees, flowers and vegetables, is long in lasting period, and has a relatively good effect of regulating growth of crops, and drug delivery times is obviously reduced.

Description

Technical field [0001] The invention relates to the field of bactericides, in particular to a bactericidal composition containing penflufen and carvacrol. Background technique [0002] Powdery mildew or rust is currently the two major types of crop diseases in China that are more harmful. For example, wheat powdery mildew (Blumeriagraminis (DC.)SpeerErysiphegraminisDC.E.graminisDC.f.sp.triticiMarchal) Metamorphosis, belonging to the Ascomycotina fungus, is a worldwide disease. It is distributed in all major wheat-producing countries. It is common in Shandong coastal areas, Sichuan, Guizhou, and Yunnan, and the damage is also serious. In recent years, the disease has become more and more serious in the wheat areas of Northeast, North China and Northwest China. The disease can affect the above-ground organs of wheat plants, but mainly leaves and leaf sheaths. When the disease is severe, glumes and awns can also be affected. Wheat rust is divided into stripe rust (Pucciniastriiform...
