Embodiment 1、20

[0058] Embodiment 1, 20.2% metrafenone boscalid emulsifiable concentrate

[0059] Metrafenone 20%, boscalid 0.2%, Nongru No. 500 2% (emulsifier), and xylene (solvent) were supplemented to 100%.

Embodiment 2、15

[0060] Example 2, 15.5% Metrafenone Boscalid EC

[0061] Metrafenone 15%, boscalid 0.5%, Nongru No. 500 3% (emulsifier), and xylene (solvent) were supplemented to 100%.

[0062] Microemulsion, water emulsion embodiment

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

Embodiment 3、5

[0064] Embodiment 3, 5% metrafenone boscalid microemulsion

[0065] Metrafenone 2.5%, Boscalid 2.5%, Toluene 8% (solvent), Nongru No. 500 8% (emulsifier), Nongru No. 600 5% (emulsifier), Nongru No. 1600 5% (emulsifier) agent), sodium lauryl sulfate 2% (humectant), ethylene glycol 5% (antifreeze), water replenished to 100%

Abstract

The invention discloses a sterilizing combination. The effective components of the sterilizing combination are metrafenone and boscalid, and the mass ratio of metrafenone to boscalid is (1:100) to (100:1). The combination is remarkable in synergistic effect and high in preventive effect, and is suitable for preventing and curing various diseases on melons, fruit and vegetables and particularly suitable for preventing and curing powdery mildew.

Description

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