Embodiment 1

[0009] Embodiment 1, 45% metconazole · thiamethoxam wettable powder

[0010] Meconazole 23%, thiamethoxam 22%, fatty alcohol polyoxyethylene ether 10%, pull open powder BX 6%, bentonite supplemented to 100%. After the above-mentioned materials are uniformly mixed in a double-screw mixer, they are pulverized to a size below 800 mesh by an airflow mill to obtain a 45% metconazole·thiamethoxam wettable powder meeting the standard.

Embodiment 2

[0011] Embodiment 2, 35% metconazole · thiamethinone water-dispersible granules

[0012] 18% metconazole, 17% thiamethoxam, 8% alkylphenol polyoxyethylene ether, 5% sodium lauryl sulfate, 1% ammonium sulfate, 0.2% aluminum oxide, 8% starch, diatomaceous earth to make up to 100%. The above-mentioned materials are made into water suspension, and the particle size of the particles in the suspension is crushed and ground to below 5u with a pipeline crushing pump and a sand mill to make a water suspension, and the solid content in the suspension is adjusted to an appropriate ratio. The suspending agent is pumped into a special spray granulation drying tower with a mud pump to prepare 35% metconazole·thiamethonil water-dispersible granules meeting the standard.

Embodiment 3

[0013] Embodiment 3, 32% metconazole · thiamethinone suspending agent

[0014] Meconazole 16%, Thiemadil 16%, Fatty Alcohol Polyoxyethylene Ether 6%, Calcium Alkylbenzene Sulfonate 8%, Polyethylene Glycol 2%, Silicone Oil 0.2%, Propylene Glycol 3%, soft water to make up to 100% . The above materials are made into water suspension, and the suspension is crushed and ground to a particle size below 5u by a pipeline crushing pump and a sand mill to obtain a standard 32% metconazole-thiamethoxam suspending agent.

Abstract

The invention discloses a fungicidal composition containing metconazole and benziothiazolinone and an application of the fungicidal composition. The fungicidal composition is characterized metconazole and benziothiazolinone are taken as main active ingredients, wherein a weight ratio of metconazole to benziothiazolinone is (40-1):(1-40), and a preferred weight ratio is (10-1):(1-10). The composite can be prepared into wettable powder, water dispersible granules and a suspending agent, and used for preventing and treating wheat scab, powdery mildew and a rust disease, and has obviously superior prevention and treatment effects than a single dose.

Description

technical field [0001] The invention relates to a bactericidal composition containing metconazole and thiamethoxam and its application Background technique [0002] Metconazole (Metconazole) is a high-efficiency, broad-spectrum, systemic triazole fungicide, which has the functions of protection, treatment and eradication, so it is widely used in various crop diseases caused by fungi such as Ascomycetes and Basidiomycetes. Prevention and treatment. Meconazole is currently one of the effective agents for the control of wheat head blight. Its mechanism of action is mainly to inhibit the biosynthesis of ergosterol and destroy the cell membrane function of the bacteria, thereby inhibiting or disturbing the development of appresses and haustoria. , hyphae and spore formation, can also lead to increased membrane leakage, thereby promoting the pathogenic death of pathogenic bacteria. Meconazole can not only reduce the severity of wheat head blight in the field, but also reduce the...
