example 1

[0019] Preparation of Example 1 8% Mixed Fatty Acid Copper Sulfate Water Emulsion

[0020] formula:

[0021] Mixed fatty acids: 7.6%;

[0022] Copper sulfate: 0.4%;

[0023] Methanol: 10%;

[0024] Emulsifier HY-6401C: 11%;

[0025] Deionized water: make up.

[0026] Antifreeze, can use ethylene glycol, propylene glycol, glycerin, methanol, hexanediol, uremic acid, ammonium sulfate, NaCl, CaCl 2 etc., the preferred antifreeze is methanol.

[0027] The emulsifier can be anionic and nonionic surfactants commonly used in pesticides, such as anionic surfactants: sulfonates, sulfates, lignosulfonates, nonionic surfactants such as: triphenylethylphenol Oxyethylene ether, 0203B, 2201, Nongru 500, Nongru 600, Nongru 1601, mixture of ethylene oxide-propylene oxide block copolymer, ethoxylated alkyl phenyl ether, etc. The preferred surfactant is tristyrylphenol polyoxyethylene ether, so the emulsifier HY-6401C (full name is: calcium dodecylbenzenesulfonate and tristyrylphenol pol...

[0029] formula:

[0030] Mixed fatty acids: 22.8%;

[0031] Copper sulfate: 1.2%;

[0032] Methanol: 10%;

[0035] Example 3 8% Mixed Fatty Acid Copper Sulfate Water Emulsion Indoor Formula Screening Report

[0036] In order to clarify the prevention and control effect of mixed fatty acid and copper sulfate and their different ratios on tobacco virus disease, we compounded the self-made mixed fatty acid and commercially available copper sulfate to make mixed fatty acid-copper sulfate aqueous emulsion , a significant synergistic effect was found. After indoor formula screening, the best ratio was selected as mixed fatty acid: copper sulfate 7.6:0.4, and the synergistic coefficient was 218.8, which is extremely significant.

Abstract

The invention relates to a composition preparation of copper sulphate and mixed fatty acid for resisting a tobacco mosaic disease, comprising copper sulphate, mixed fatty acid, an emulsifier, an anti-freeze agent and water, wherein the weight ratio range of the copper sulphate and the mixed fatty acid is 1:1-28, the optimal proportion is 1:19, and the form of the composition preparation is aqueous emulsion. The composition preparation of copper sulphate and mixed fatty acid for resisting a tobacco mosaic disease is used for preventing crop virus diseases and has high efficiency, low toxicity,low cost and no environmental pollution.

Description

technical field [0001] The invention relates to pesticides, in particular to a combination of copper sulfate and mixed fatty acids for preventing and treating tobacco mosaic disease. Background technique [0002] Plant virus, the earliest researcher Ivanovsky (Iwanowski) discovered tobacco mosaic virus (Tobacco mosaic virus, TMV) as early as 1892, and in 1896, German plant pathologist Adolf Mayer proposed the name of tobacco mosaic virus disease ( Mosaikkrankheic), he injected the juice of diseased plants infected with tobacco mosaic disease into healthy tobacco plants, and the healthy tobacco plants produced the same symptoms, which proved that tobacco mosaic disease could be transmitted by contact; in 1898, the Netherlands Beijerinck found that the source of tobacco mosaic disease is a tiny infectious "infection fluid", called filter virus, and determined that this is a type of virus that can only replicate in host cells. [0003] From the discovery of plant virus pathoge...
