Embodiment 1

[0070] Example 1 Efficacy Test of 80% Propineb Tridemorph WP in Controlling Apple Powdery Mildew

[0071] Propineb 70%, tridemorph 10%, polycarboxylate 5%, sodium lauryl sulfate 3%, saponin powder 2%, white carbon black 10%, the mixture is jet milled to obtain 80% Propineb · Tridemorph wettable powder. 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 the medicine, the effects of preventing and treating apple powdery mildew were 91.5%, 96.4%, respectively. The 70% propineb wettable powder and the 750g / L tridemorph emulsifiable concentrate were diluted 500 times and 1500 times respectively in the same way. The control effects were 62.3% and 71.9% respectively 14 days after treatment.

Embodiment 2

[0072] Example 2 Efficacy Test of 72% Zinc Tridemorph WP in Controlling Apple Rot

[0073] Zinc 64%, tridemorpholine 8%, lignin sulfonate 4%, tea 4%, white carbon black 10%, kaolin to 100%, the mixture is jet milled to obtain 72% zinc ·Tracemorpholine wettable powder. 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 application, the effects of preventing and treating apple rot were 92.3% and 96.8%, respectively. The 70% Zinc wettable powder and 750g / L Tridemorph EC were diluted 300 times and 1500 times respectively in the same way. The control effects were 62.5% and 75.3% respectively 14 days after treatment.

Embodiment 3

[0074] Example 3 Drug Efficacy Test of 60% Disenlian · Tridemorph WP in Controlling Cucumber Downy Mildew

[0075] Disenlian 50%, tridemorpholine 10%, alkyl aryl polyoxyethylene ether 4%, sapindus powder 4%, white carbon black 12%, kaolin added to 100%, the mixture is jet milled to obtain 60% Disenlian·Tridecmorpholine wettable powder. The ratio is 2800 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 cucumber downy mildew were 91.8% and 95.6%, respectively. The 70% Daisenlian WP and 750g / L Tridemorph EC were diluted 400 times and 1400 times respectively in the same way. , the control effects were 64.4% and 75.6% respectively 14 days after the drug.

Abstract

The invention discloses a tridemorph-containing disinfection composition, containing a component A and a component B, wherein the component A is one of the following thiocarbamates disinfectants: propineb, polyram, zineb and mancozeb; the component B is tridemorph;, and the ratio of the active component A and the active component B in parts by weight is (32:1) to (1:16). The composition provided by the invention has obvious synergistic effect, can prevent multiple diseases and has good safety to crops; and the invention has the advantages that the composition is resistant to rain wash, and the drug effect is lasting.

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...
