Embodiment 1

[0030] Example 1: Epiconazole + Thiophanate-methyl

[0031] According to the weight ratio of epoxiconazole (unless otherwise specified, all refer to weight percentage) 10%, thiophanate-methyl 10%, white carbon black 5%, sodium lignosulfonate 10%, filler is kaolin, made into water dispersion Granules, the formula is diluted and sprayed by 1000-1500 times, and the field control effect is 90.4% for blight and 92.8% for powdery mildew in the field 72 hours after the application; if 10% epoxiconazole is used as a single agent to prepare a wettable powder, follow the same method After use, the control effect is 30.4% and 23.8% respectively after 72 hours; if 10% thiophanate methyl is used as a single agent to form a wettable powder and used in the same way, the control effect is 38.4% and 33.8% respectively 72 hours after the medicine. . From the comparison of the above-mentioned compounding and single-agent use, it is not difficult to understand that the control effect obtained is 2 to...

Embodiment 2

[0032] Example 2: Epiconazole + Carbendazim

[0033] According to the weight ratio of epoxiconazole (unless otherwise specified, all refer to weight percentage) 25%, carbendazim 30%, white carbon black 4%, sodium lignosulfonate 5%, and kaolin as the filler to make a wettable powder. The formula is diluted and sprayed at 1000-2000 times, and the field control effect is 93.6% for blight and 92.8% for powdery mildew in the field 72 hours after the application. If 25% epoxiconazole is used as a single agent to prepare a wettable powder, use the same method. The control effect after 72 hours is 30.4% and 23.8% respectively; if 30% carbendazim is used as a single agent to form a wettable powder and used in the same way, the control effect after 72 hours is 18.4% and 23.8% respectively. Compared with single-agent use, it is not difficult to understand that the control effect obtained is 3 to 4 times different.

Embodiment 3

[0034] Example 3: Epiconazole + Mancozeb

[0035] According to the weight ratio of epoxiconazole (unless otherwise specified, all refer to weight percentage) 45%, mancozeb 10%, xanthan gum 0.2%, glycerin 6%, Nongru 601# is 3%, water is the balance Into a suspension. The formula is diluted and sprayed by 1000 to 2500 times, and the field control effect of 72 hours after treatment is 91.7%; if 45% epoxiconazole is used as a single agent to form a wettable powder, use the same method, and the control effect will be different after 72 hours. It is 19.3% and 20.6%; if 10% mancozeb is used as a single agent to form a wettable powder and used in the same way, the 72-hour control effects will be 10.3% and 29.8% respectively. Compare the above mixing and single agent use , It is not difficult to understand that the control effect is 3-8 times different.

Abstract

The invention discloses a fungicide composition containing epoxiconazole as an active ingredient. It is composed of epoxiconazole A and fungicide B as the active ingredients, and the fungicide B component refers to thiophanate-methyl, carbendazim, mancozeb, zinc, dysonin or multi-anti-mildew Any one or two or more combinations of epoxiconazole A and fungicide B are mixed in a mass ratio of 50 to 1:1 to 50. The advantage of the present invention is that the binary fungicide composition can be To prevent and control the blight and powdery mildew that are difficult to control in agriculture, the spraying is diluted 2000 to 3000 times, and the field control effect is 90.4% for blight and 95.2% for powdery mildew 72 hours after spraying; if 45% epoxiconazole is used A single dose is formulated into an emulsion in water and used in the same way, and the control effects after 72 hours of application are 30.8% and 21.2% respectively; from the comparison of the above-mentioned compounding and single dose use, it is not difficult to understand that the difference in the control effect is 3 to 4 times.

Description

Technical field [0001] The invention relates to a pesticide bactericide composition, in particular to a bactericide composition containing an effective ingredient of epoxiconazole. technical background [0002] Most of the existing pesticide fungicides are combined with single-agent varieties and additives. This single-agent variety has the disadvantage of poor prevention and control of diseases and insect pests. The shortcomings of single-agent varieties are described below: [0003] Thiophanate-methyl: It is a common fungicide, belonging to the benzimidazole class, and a broad-spectrum systemic fungicide that can prevent and treat a variety of crop diseases. It has systemic, preventive and therapeutic effects. In addition, in recent years, the resistance to disease control alone has increased, resulting in a decline in the control effect. [0004] Carbendazim: It is also a common fungicide, belonging to the benzimidazole class, and is a highly effective, low-toxic, systemic fun...
