Problems solved by technology

[0008] Crops are infected by infectious viruses, on the one hand, it will destroy the yield of the plant itself, on the other hand, it will infect other plants and cause more serious losses
At present, there is no very effective control method for plant-infectious viruses, and the mechanism of action of mainstream antiviral agents is mainly early prevention, and the treatment effect on infected plants is poor
The inventor of the present patent application has explored an agricultural composition containing dextran sugar through in-depth research, which has an excellent control effect on plant virus damage, and this composition has not appeared in the known literature. Those of ordinary skill in the art are also difficult to know the beneficial effects of the composition for preventing and controlling plant virus damage

Embodiment 1

[0021] This example provides a field test of the control effect of an agricultural composition containing dextran on tobacco mosaic virus disease. The effective component of the agricultural composition is a composition of dextran and amino oligosaccharin.

[0022] The variety of tobacco tested was "Yunyan 87". The test site was in the tobacco production base of Wangwu Township, Jiyuan City, Henan Province, and the normal soil, fertilizer and water management was unified.

[0023] Dextran and amino oligosaccharin were compounded according to the ratio described in Table 1 to form a mixed treatment agent, and a single agent of dextran, a single agent of amino oligosaccharin, adjuvant and water were used as control agents.

[0024] During the test, the tobacco was in a long period of prosperity, the peak of the disease, the rate of diseased plants was 100%, and the highest degree of disease was 9 grades. Set up a test plot for each group of treatments, and the area of ​​each te...

Embodiment 2

[0033] This example provides a field test of the effect of an agricultural composition containing dextran on the control of tomato virus diseases. The effective component of the agricultural composition is a combination of dextran and chitosan.

[0034]The tomato variety to be tested is "Jinpeng No. 8". The test site is the greenhouse of the National Modern Agriculture Demonstration Zone in Shunqing District, Nanchong City, Sichuan Province, and the normal soil, fertilizer and water management is unified.

[0035] Dextran and chitosan were compounded according to the ratio described in Table 1 to form a mixed treatment agent, and a single agent of dextran, a single agent of chitosan, adjuvants and water were used as control agents.

[0036] Set up a test plot for each group of treatments, and the area of ​​each test plot is 20m 2 , the plots are arranged randomly, and the plots are separated by guard lines. The first spraying was for the prevention and control of tomato viru...

Embodiment 3

[0043] This example provides a field test of the control effect of an agricultural composition containing dextran on cucumber mosaic virus disease. The effective components of the agricultural composition are a combination of dextran and lentinan. The test site was selected in the cucumber greenhouse of Songling Cucumber Research Institute in Xi'an, Shaanxi Province. The cucumber variety is a self-fertile variety.

[0044] Dextran and lentinan were compounded into a mixed treatment agent according to the ratio described in Table 3. The single agent of dextran, the single agent of lentinan and the adjuvant were respectively used as the control treatment agents, and the clear water was used as the blank control.

[0045] Set up a test plot for each group of treatments, and the area of ​​each test plot is 20m 2 , Set up isolation measures between each plot, investigate the condition of each plot on the 5th day after transplanting, and spray pesticides. When spraying the pesticid...

Abstract

The invention discloses an agricultural composition containing glucosene. The agricultural composition comprises an effective component A and an effective component B. The component A is glucosene, and the component B is one selected from amino-oligosaccharin, chitosan and lentinan. The agricultural composition and the auxiliary bag are used in a compatible mode, wherein the effective component of the auxiliary bag is a compound of diosgenine and L-pyroglutamic acid, and a mass ratio of the diosgenine to the L-pyroglutamic acid is 3: 2. Within a certain ratio range, the agricultural composition has excellent prevention and treatment effects on tobacco mosaic virus, tomato virus and cucumber mosaic virus, and can promote yield increase of crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation and planting, and relates to an agricultural composition containing dextran. Background technique [0002] Infectious plant diseases are one of the main threats in the current global agricultural cultivation and planting process. These infectious diseases are caused by various pathogens and have a certain degree of transmission, causing serious harm to economic crops and causing crop yield losses. Or product quality is reduced, and the economic loss that agricultural and forestry production is caused every year is huge. Traditional agricultural control measures are heavy workload, complicated operation, and the effect is not ideal. Although the chemical control method is simple and easy to operate, it poses a great threat to the environment and ecology. Therefore, it is particularly urgent to develop new control agents with good control effect and little environmental pollution....
