Embodiment 1

[0067] Example 1 Drug Efficacy Test of 80% Propinezine·Thiabendazole WP for Controlling Citrus Penicillium

[0068] Propineb 50%, thiabendazole 30%, polycarboxylate 5%, sodium lauryl sulfate 3%, saponin powder 2%, kaolin 10%, the mixture is jet milled to produce 80% propineb · Thiabendazole wettable powder. The proportion is 1500mg(a.i.) / L liquid medicine, soak the fruit for 3-5 minutes, dry and put into frame. Can control citrus penicillium, green mold, stem rot, flower rot. Calculate the control effect after 30 days, and the control effect is above 97.3%. The 70% propineb wettable powder and the 15% thiabendazole suspension are used in the same way at 3000mg (a.i.) / L and 2000mg (a.i.) / L respectively , the control effects were 75.3% and 89.4% after 30 days of treatment.

Embodiment 2

[0069] Example 2 Drug Efficacy Test of 65% Ziben·Thiabendazole WP in Controlling Cabbage Downy Mildew

[0070] Ziben 47%, Thiabendazole 18%, Lignosulfonate 4%, Tea Cucumber 4%, White Carbon Black 8%, Kaolin 19%, the mixture is jet milled to produce 65% Zibend. Spirit wettable powder. The ratio is 5000 times diluted and sprayed, sprayed at the early stage of the disease, sprayed once every 7 days, a total of 2 sprays, the disease index was investigated 7 days and 14 days after the last spraying, and the control effect was calculated. 7 days and 14 days after application, the effects of controlling downy mildew of Chinese cabbage were 91.7% and 94.2%, respectively. The 70% zinc WP and 15% thiabendazole suspension were diluted 500 times and 3000 times respectively in the same way. , the control effects were 63.4% and 75.5% respectively 14 days after the drug.

Embodiment 3

[0071] Example 3 Drug Efficacy Test of 55% Disenlian·Thiabendazole WP for Controlling Botrytis cinerea

[0072] Daisenlian 45%, thiabendazole 10%, alkyl aryl polyoxyethylene ether 4%, sapindus powder 4%, white carbon black 7%, kaolin 30%, the mixture is jet milled to obtain 55% Senlian·thiabendazole wettable powder. The ratio is 3500 times diluted and sprayed, sprayed at the early stage of the disease, sprayed once every 7 days, a total of 2 sprays, the disease index was investigated 7 days and 14 days after the last spraying, and the control effect was calculated. 7 days and 14 days after application, the effects of preventing and treating botrytis cinerea were 91.8% and 94.6%, respectively. 70% WP and 15% thiabendazole suspension were diluted 450 times and 3000 times respectively in the same way. The control effects were 62.3% and 78.7% respectively 14 days after treatment.

Abstract

The invention discloses a probenazole-containing bactericide composition. The bactericide composition contains A and B, wherein A is zineb, mancozeb, propineb or thioneb serving as dithiocarbamate-type bactericide; B is probenazole; and the weight-part ratio of two active components A and B is 1-100:1-50. The composition has obvious synergy, can be used to prevent a plurality of diseases, is goodin safety for crops, and also has the characteristics of resistance to rainwater erosion, lasting efficacy 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 fungicide composition containing two active components. Background technique [0002] Thiabendazole (thiabendazole) belongs to the class of benzimidazoles, the molecular formula is C 10 h 7 N 3 S, chemical name: α-(4-thiazolyl)-1H-benzimidazole. [0003] [0004] Thiabendazole belongs to the class of benzimidazoles, and its mechanism of action is to inhibit fungal mitochondrial respiration and cell proliferation. It has a systemic conduction function, and can conduct to the top when applied to the root, but not to the base. Antibacterial activity is limited to Ascomycetes, Basidiomycetes, and Deuteromycetes, but is inactive against Oomycetes and Zygomycetes. [0005] Propineb (propineb), the molecular formula is (C 5 h 8 N 2 S 4 Zn) x , Chemical name: zinc propenyl bisdithiocarbamate. [0006] Propineb belongs to phenylthiocar...
