Embodiment 1

[0044] Embodiment 1 The preparation of 20% compound A octocalid suspension

[0045]Proportion of raw materials by weight: compound A 1%, octobinol 19%, calcium dodecylbenzenesulfonate 2%, phenethylphenol formaldehyde resin polyoxyethylene ether 3%, phenethylphenol polyoxyethylene ether 2%, naphthalenesulfonate dispersant 1%, xanthan gum 0.2%, magnesium aluminum silicate 1.5%, ethylene glycol 5%, water replenishment 100%; prepared according to the conventional production method of water suspension.

[0046] The samples of Example 1, the control drug 30% octocalid suspension (made by the laboratory) and 2% compound A suspension (made by the laboratory) were used as a comparison to carry out a drug effect comparison test.

[0047] Control object: Botrytis cinerea of ​​tomato.

[0048]

[0049] The average temperature during medication is 21-25°C, and the weather is mainly sunny. The above data show that the compound preparation has a significantly improved anti-bacterial effe...

Embodiment 2

[0050] Embodiment 2: the preparation of 36% compound A octocalid water-dispersible granules

[0051] Raw materials by weight: 18% of compound A, 18% of octoprobin, 10% sodium methylene bis-tetrasulfonate, 7% naphthalenesulfonate formaldehyde condensate, 10% polycarboxylate, and the rest is supplemented with ammonium sulfate . Prepared according to conventional granule production methods.

[0052] The samples of Example 2, the control drug 30% octocalid WP (made by the laboratory) and 8% compound A suspension concentrate (made by the laboratory) were used as a comparison to carry out a drug effect comparison test.

Abstract

The invention provides an antiviral composition containing Xinjunan, belonging to the field of pesticides. The antiviral composition comprises the following main active components: Xinjunan and an acylhydrazone-structuring-containing compound A, wherein a weight ratio of the acylhydrazone-structuring-containing compound A to Xinjunan is 1: 40 to 10: 1, and the acylhydrazone-structuring-containingcompound A and Xinjunan account for 1.5 to 60% of the total weight of the composition. A dosage form for the antiviral composition may be a suspending agent, wettable powder, water-dispersible granule, emulsion in water, etc. The antiviral composition of the invention is mainly applied to prevention and treatment of a variety of crop viruses, such as tobacco mosaic virus disease, rice stripe, riceleaf blight, tomato mosaic virus disease and maize dwarf mosaic virus disease.

Description

technical field [0001] The invention belongs to the technical field of pesticides and provides an antiviral composition containing octocalid, in particular an antiviral composition containing octocalid or its acetate and compound A containing an acylhydrazone structure. Background technique [0002] Compound A containing an acylhydrazone structure is a class of pesticide active ingredients developed by Nankai University. The chemical name of this type of active compound A is (1S,3S)-N'-(4-chlorophenylene methyl)-1-methyl-2,3,4,9-tetrahydropyrido[3,4-b]indole-3-carboxylhydrazide). This type of compound A containing an acylhydrazone structure has very good biological activity against tobacco mosaic virus, tomato mosaic virus, etc. At the same time, this type of compound is easily absorbed by plants, easy to degrade in the environment, and has good environmental compatibility . [0003] Compound A mainly includes the following compounds: [0004] [0005] Cycloprodil, an ...
