Embodiment 1

[0037] The inventor has carried out a large number of indoor bioassay tests and field drug efficacy tests, and found that the combination of activated ester and any of the above-mentioned methoxyacrylate compounds has a significant synergistic effect on powdery mildew, downy mildew, etc., not only It is simply the addition of the two agents (see Bioassay Examples 1, 2 for details). Bioassay Example 1: Indoor Toxicity Determination of Cucumber Powdery Mildew Bacteria Combined with Activated Ester and Methoxyacrylate Fungicides

[0038] Test object: Cucumber powdery mildew (collected from the field)

[0039] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Two cucumber seedlings at the true leaf stage were selected in pots with the same growth potential, and 5 pots were selected for each treatment, and the numbers were reserved for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. For the test tr...

[0060] Biological Assay Example 2: Indoor Toxicity Test of Cucumber Downy Mildew Combined with Activated Ester and Methoxyacrylate Fungicides

[0061] Test object: Cucumber downy mildew (Pseudoperonospora cubensis)

[0062] The potted method was used in this experiment. Two cucumber seedlings at the true leaf stage with the same growth were selected, and 5 pots of cucumber seedlings for testing were selected for each treatment, and the numbers were reserved for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. Five concentration gradients were set for each agent, and the same amount of water sprayed was used as the blank control. Spray and inoculate the sporangia suspension of cucumber downy mildew after 24 hours of chemical treatment. sporangia, the concentration is 3×10 5 sporangia suspension per mL. After inoculation, cucumber seedlings were placed in an artificial climate box (relative humidity 100%, temperature 15-20°C) for cultivation,...

Embodiment 2

[0084] Embodiment 2: 20.2% activated ester · erythoxystrobin suspension concentrate

[0085] Activated ester 0.2%, erythoxystrobin 20%, polycarboxylate (dispersant) 10%, tea dry powder (wetting agent) 3%, polyvinyl alcohol (thickener) 2%, bentonite (thickener) ) 1%, ethylene glycol (antifreeze) 5%, and water to make up to 100%.

Abstract

The invention relates to a sterilizing composition containing active ester, which comprises effective components such as active ester (A) and a strobilurin bactericide (B), wherein the strobilurin bactericide is chosen from azoxystrobin, kresoxim-methyl, pyraclostrobine, metominostrobin, dimoxystrobin, trifloxystrobin, picoxystrobin, fluoxastrobin, enestroburin, 2-[2-(2,5-phenoxy-dimethyl) phenyl-methyl-3- methoxy acrylate (ZJ0712) or 2-imino-methyl-N-methyl-2-[[[[[[4-(2,6-dimethyl)phenyl]-3-butylene-2-yl]imino]epoxide]phenyl]amide (SYP-1620), the weight ratio of the A and B is 100:1-1:100, and the content of the active component in the composition is 5-80 in percentage by weight. The composition can be prepared into suspending agents, wetting powder, water dispersible granules, and the like. The sterilizing composition can be applied to farmlands, orchards and the like and is used for controlling various plantdiseases of grains, vegetables, fruit trees, flowers, and the like, in particular powdery mildew and downy mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing an activated ester and a methoxyacrylate bactericide, and belongs to the field of agricultural bactericides. 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 Grape powdery mildew caused by Uncinula necator; Powdery mildew of more than 80 kinds of trees such as ...
