Antiviral composition containing daucosterol and sitosterol and antiviral application of antiviral composition

Abstract

The invention relates to an antiviral composition containing daucosterol and sitosterol and antiviral application of the antiviral composition. The weight ratio of daucosterol to sitosterol in the antiviral composition is 1:50 to 50:1. Compared with single use of daucosterol or sitosterol, the antiviral composition disclosed by the invention has a significant synergistic effect on a variety of plant viruses, and has the characteristic of long lasting period at the same time, so that the service life of an active compound is prolonged, and the generation of drug resistance of the plant viruses is delayed.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to the field of anti-plant viruses, in particular to an anti-virus composition of carotin and sitosterol and its anti-virus application. Background technique

[0002] Plant viral diseases pose a serious threat to crop yield and quality worldwide, causing a 10-30% reduction in yield and an economic loss of about 20 billion U.S. dollars each year. my country is a large agricultural country, and the economic losses caused by viral diseases to food production, horticultural crops, and cash crops amount to more than tens of billions of yuan every year. Therefore, there is an urgent need to develop antiviral drugs. Foreign countries have increased research in this area since the early 1960s. In 1985, the alginic acid casein (Mosanon) registered in Japan was extracted from Mirabilis jasmine and Lentemin (Lentemin), an extract of mushroom juice, was used to prevent and treat tomato viruses. sick...

[0046] Example 1 (0.02% soluble liquid, active ingredient ratio 1:1)

[0047] Carotin 0.01%, Sitosterol 0.01%, Nongru 2201 # 7.5%, agricultural milk 100 # 4.5%, dimethylformamide 8%, cyclohexanone to make up to 100%.

Embodiment 2

[0048] Example 2 (2.1% soluble liquid, active ingredient ratio 1:20)

[0049] Carotin 0.1%, sitosterol 2%, Nongru 1601 # 5%, Nongru 0201B 6%, N-methyl-pyrrolidone 10%, isopropanol to 100%.

Embodiment 3

[0050] Example 3 (0.6% soluble liquid, active ingredient ratio 1:5)

[0051] Carotin 0.1%, Sitosterol 0.5%, Nongru 500 # 5%, Nongdai 600 # 9%, cyclohexanone 8%, and isopropanol to make up to 100%.

[0052] 2. Preparation of EC

[0053] The general preparation method is as follows: according to the requirements of the formula, add solvent, original drug and emulsifier respectively, mix evenly, and if necessary, heat and dissolve in a water bath to obtain a transparent emulsifiable oil.
