Tomato virus disease inhibitor and preparation method thereof

Abstract

The invention relates to a tomato virus disease inhibitor. The tomato virus disease inhibitor comprises 50g of potassium permanganate, 15g of vitamin C, 30g of astragalus, 20g of dried alum, and 15g of borneol. A preparation method comprises the following steps of: taking various raw materials according to a weight proportion, crushing the astragalus, the dried alum and the borneol, adding papayapowder at the temperature of 10+ / -1 DEG C, obtaining a fluid body by adopting a supercritical extraction technology, adding the potassium permanganate and the vitamin C, and stirring uniformly to obtain the inhibitor. Various components are interactive; and the inhibitor can decompose virus proteins, damage the structures of viruses so as to degenerate the viruses, can effectively inhibit the growth of the viruses, improve the stress resistance of plants, regulate the metabolism of crops to stimulate the growth of the crops, contribute to the prognosis recovery of the plants, particularly leaves, has the characteristics of quick response, and few pesticide application times, and makes the leaves recover well. When the inhibitor diluted 500 times is used for spraying the leaves, the control effect at 7th day reaches 73.4 percent, and the control effect at 30th day reaches 82.3 percent; and the effects of controlling the fruit-setting number and fruit-dropping number of tomato plants are high, and the effect of controlling diseased plants is good.

Description

Technical field [0001] The invention relates to a plant virus disease inhibitor and a preparation method thereof, in particular to a tomato virus disease inhibitor, belonging to the technical field of agriculture. Background technique [0002] Tomato virus disease is one of the main diseases in tomato production. It is widely distributed in my country, almost all over all tomato production areas. Spring tomatoes are reduced by about 30% each year due to the disease, and the loss of summer and autumn tomatoes is more serious. In some years, there may be some The plot almost never harvested, which seriously affected tomato production. [0003] The field symptoms of tomato virus disease are diverse. Sometimes two or more different types of symptoms appear on the same plant at the same time. Common symptoms are: [0004] Mosaic type: The leaves are mottled or slightly shrunken in shades of yellow and green; [0005] Fern leaf type: the plant is dwarfed, the upper leaves are linear, the mi...
