Embodiment 180

[0063] Example 180% Proceeding Zinc·Dipropamid WP Experiment on the Control of Tomato Late Blight

[0064] 70% of Zinc Propionate, 10% of Dipropamidil, 5% of Polycarboxylate, 3% of Sodium Lauryl Sulfate, 2% of Saponin Powder, 10% of Kaolin, the mixture was air-milled to obtain 80% of Propylene Senzin · Dipropamidil WP. The ratio is diluted by 5000 times and sprayed at the initial stage of the disease, once every 7 days, for a total of 2 times. The effects of preventing and controlling tomato late blight were 91.7% and 96.2% respectively 7 days and 14 days after the treatment. 70% Prosenzinc WP and 250g / L Dipropamidil suspension were diluted 500 times and 1500 times respectively according to the same method. After use, the control effect was 65.4% and 73.5% respectively 14 days after the drug.

Embodiment 260

[0065] Example 260% Efficacy test of dysenzin·dipropamid WP in controlling tomato early blight

[0066] Dysenzinc 30%, Dipropamidil 30%, Lignin sulfonate 4%, Chaku 4%, Silica 8%, Kaolin 24%, the mixture was air-milled to obtain 60% Dysenzinc· Dipropamidil wettable powder. The ratio was diluted by 4000 times and sprayed at the initial stage of the disease, once every 7 days, for a total of 2 times. The disease index was investigated and the control effect was calculated 7 days and 14 days after the last application. The effects of preventing and controlling tomato early blight were 90.5% and 94.7% respectively 7 days and 14 days after the treatment. The 70% Zinc WP and 250g / L Dipropyram suspension were diluted 300 times and 1500 times respectively according to the same method. After use, the control effect was 63.4% and 75.6% respectively 14 days after the drug. Example 360% Efficacy test of dysenlian·dipropamid WP in the control of cucumber downy mildew

Embodiment 360

[0067] 50% of Daisenlian, 10% of pyraclostrobin, 4% of alkyl aryl polyoxyethylene ether, 4% of Sapindus japonica powder, 7% of white carbon black, 25% of kaolin, and the mixture was air-milled to obtain 55 % Dysenlian · Dipropamid WP. The ratio is diluted by 3500 times and sprayed at the initial stage of the disease, once every 7 days, for a total of 2 times, and the disease index is investigated and the control effect is calculated 7 and 14 days after the last application. The effects of controlling cucumber downy mildew were 91.8% and 96.6% respectively 7 days and 14 days after the treatment. 70% Dysenlian WP and 250g / L Dipropamid suspension were diluted 350 times and 1300 times in the same way. 14 days after the drug was used, the control effects were 62.4% and 76.7%, respectively.

Abstract

The invention discloses a bactericidal composition containing mandipropamid, which is a bactericidal composition containing A and B, wherein A is selected from any one of the followed dithiocarbamates bactericide: propineb, metiram and zineb; B is selected from the mandipropamid; and the weight part ratio of the active component A to the active component B is (1-100) : (1-50). The composition disclosed by the invention has remarkable synergistic effect, can be used for preventing various diseases, has good safety for plants, and has the advantages of rain drop erosion resistance, durable pesticide effect and the like.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and relates to the preparation and application of a bactericidal composition containing two active components. Background technique [0002] Cyazofamid, molecular formula: C 23 H 22 CINO 4 , chemical name: 2-(4-Chloro-phenyl)-N-[2-(3-methoxy-4-(2-propynyloxy)-phenyl-ethanyl]-2-(2 -Propynyloxy)-acetamide. [0003] [0004] Dipropamidil is an amide fungicide. Its mechanism of action is to inhibit the biosynthesis of phospholipids, and it has a good control effect on the vast majority of leaf and fruit diseases caused by oomycetes. It has high activity to the spores in the germination stage, and can inhibit the growth of mycelium and the formation of spores. It can be quickly absorbed through the leaves and stay in the waxy layer of the leaf surface to protect the leaves. [0005] The long-term use of a single dose of pyraclostrobin can easily make the disease resistant to the drug, ...
