Embodiment 140

[0060] Example 140% Prochloraz Tridemorph Emulsion Efficacy Test for Controlling Rice Bakanae Disease

[0061] Prochloraz 30%, Tridemorph 10%, Methanol 5%, Alkylphenol Polyoxyethylene Ether Phosphate 3%, Polyethylene Glycol 3%, Alkylbenzene Sulfonate Calcium 5%, Sodium Chloride 2% 1. Deionized water was added to 100% to obtain 40% prochloraz·tridecmorpholine aqueous emulsion. The ratio is 3000 times diluted and sprayed, sprayed at the early stage of the disease, and sprayed once every 7 days, a total of 3 sprays, and the disease index was investigated 7 days and 14 days after the last spraying, and the control effect was calculated. The effects of preventing and treating rice bakanae 7 days and 14 days after the drug were 91.5%, 96.4%, respectively, and 25% prochloraz EC and 750g / L tridemorph EC were diluted 500 times and 1500 times respectively in the same way. After 14 days, the control effects were 62.3% and 71.9%, respectively.

Embodiment 245

[0062] Example 245% Imazalil · Tridemorph Emulsion Efficacy Test for Controlling Apple Rot

[0063] Imazalil 5%, tridemorph 40%, alkylbenzene sulfonate 4%, alkylphenol polyoxyethylene ether phosphate 4%, acetone 5%, ethylene glycol 3%, deionized water to 100 %, 45% imazalil·tridemorph aqueous emulsion was obtained. The ratio is 3000 times diluted and sprayed, sprayed at the early stage of the disease, and sprayed once every 7 days, a total of 3 sprays, and 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 treatment, the effects of preventing and treating apple rot were 92.3% and 96.8%, respectively. The 25% imazalil EC and the 750g / L tridemorph EC were diluted 300 times and 1200 times respectively in the same way. The 14-day control effects were 62.5% and 75.3%, respectively.

Embodiment 350

[0064] Example 350% Prochloraz Tridemorph Microemulsion Efficacy Test of Controlling Cucumber Powdery Mildew

[0065] Add prochloraz 10%, tridemorph 40%, castor oil polyoxyethylene ether 5%, isobutanol 4%, urea 3%, polyvinyl alcohol 1%, deionized water to 100%, and the mixture is jet milled , Prepared 50% prochloraz · tridemorph microemulsion. 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. The effects of preventing and treating powdery mildew of cucumber were 91.8% and 95.6% respectively 7 days and 14 days after the application. The 25% prochloraz EC and the 750g / L tridemorph EC were diluted 600 times and 1800 times respectively in the same way. The 14-day control effects were 64.4% and 75.6%, respectively.

Abstract

The invention discloses a bactericidal composition containing tridemorph, which is a bactericidal composition containing A and B. A is imazalil or prochloraz, and B is tridemorph, wherein the weight part ratio of the active component A to the active component B is 32:1 to 1:32. The composition has obvious synergic effect, can prevent various diseases and ensures high safety to crops; and moreover, the composition has the advantages of rain resistance, drug effect durability 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 fungicidal composition containing tridemorpholine. Background technique [0002] Tridemorph is a morpholine fungicide. Molecular formula is C 19 h 39 NO (approximately), chemical name: 2,6-dimethyl-4-tridecylmorpholine. [0003] Tridemorph is a broad-spectrum systemic fungicide with protective and therapeutic effects, which can be absorbed by the roots, stems and leaves of plants, and is effective against various plant diseases caused by basidiomycetes, ascomycetes and half-knowledge fungi. It mainly inhibits the biosynthesis of ergosterol in pathogenic bacteria. [0004] Long-term use of a single dose of trimorpholine can easily lead to drug resistance in diseases, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development of the environment. The comp...
