Embodiment 1、20

[0058] Example 1, 20.2% benzophenone·propoxyquinoline EC

[0059] The benzophenone 20%, the prooxyquin 0.2%, the agricultural milk No. 500 2% (emulsifier), and xylene (solvent) are supplemented to 100%.

Embodiment 2、15

[0060] Example 2. 15.5% benzophenone·propoxyquine EC

[0061] The benzophenone 15%, the prooxyquin 0.5%, the agricultural milk No. 500 3% (emulsifier), and xylene (solvent) are supplemented to 100%.

[0062] Examples of microemulsions and water emulsions

[0063] According to the distribution ratio of each group, the active components are dissolved in the solvent and the co-solvent, the surfactant is added, and the oil phase is obtained by mixing uniformly. The water-soluble components and water are mixed to prepare a water phase, and then the oil phase is added to the water phase or the water phase is added to the oil phase, and the mixture is stirred while adding to prepare a microemulsion or water emulsion.

Embodiment 3

[0064] Example 3. 5% benzophenone·propoxyquin microemulsion

[0065] Benzophenone 2.5%, Proquinoline 2.5%, Toluene 8% (solvent), Nongru 500 8% (emulsifier), Nongru 600 5% (emulsifier), Nongru 1600 5% (emulsification Agent), sodium lauryl sulfate 2% (humectant), ethylene glycol 5% (antifreeze), water to 100%

Abstract

The invention discloses a fungicide composition adopting metrafenone as a main component. The fungicide composition comprises effective components metrafenone and proquinazid at the mass ratio of (1:100) to (100:1). The composition is obvious in synergistic effect, high in control effect, suitable for prevention and treatment of various diseases on cereals, melons, fruits and vegetables and especially suitable for prevention and treatment of powdery mildew.

Description

Technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition with benzophenone as the main component and its application for preventing and curing crop diseases, belonging to the technical field of pesticides. Background technique [0002] Powdery mildew is a plant disease caused by the Erysiphacesae family of fungi. Mostly ectoparasitic, all or most of the mycelium is exposed on the surface of the host plant's leaves, stems, shoots, buds, flowers and fruits, and produces a large amount of mycelium, conidiophores and conidia The white powder visible to the naked eye. [0003] Powdery mildew is widespread all over the world, and it is especially common to damage dicotyledonous plants. The main powdery mildews in China are cereal powdery mildew caused by Ery-siphe graminis; powdery mildew caused by Sphaerotheca fuliginea in melons, beans, hemp and other plants ; Wheat powdery mildew caused by Uncinula necator; powdery mild...
