Problems solved by technology

At present, there is no very effective agent for the prevention and treatment of plant virus diseases. The mechanism of action of antiviral agents is mainly to inhibit virus infection, inhibit virus proliferation and induce plant resistance. The prevention and treatment of virus diseases is mainly reflected in the early prevention effect, and the effect is general. 40-80%, and the treatment effect is poor

Embodiment 1

[0020] This example provides a field test on the control effect of a functional agricultural composition containing triacontanol and polysaccharides on tomato virus diseases. The effective component of the functional agricultural composition is a composition of triacontanol and dextran.

[0021] Those of ordinary skill in the art know that there are three common types of tomato virus diseases: mosaic disease, stripe disease and fern leaf disease, among which mosaic disease is the most common. Symptoms such as chlorosis, yellowing, dwarfing, arbuscular branches, mosaic leaves and deformities will appear after the plant becomes ill, and finally the yield will drop sharply.

[0022] The test site of this embodiment is selected in a vegetable greenhouse in Feicheng City, Shandong Province, and the variety to be tested is "Jinpeng No. 1" tomato. Triacontanol and dextran were compounded into a mixed treatment agent according to the ratio described in Table 1, and triacontanol, dext...

Embodiment 2

[0040] This example provides a field test on the control effect of a functional agricultural composition containing triacontanol and polysaccharide on tobacco mosaic virus disease. The effective component of the functional agricultural composition is a composition of triacontanol and chitosan.

[0041] The test site of this embodiment is selected in Dalongtan Township, Yunnan Province, and the "Yunyan 85" self-cultivated by the Tobacco Seedling Base in Renhe District is used as the test object.

[0042] Triacontanol and chitosan were compounded according to the ratio described in Table 2 to form a mixed treatment agent, and a single agent of triacontanol and dextran was used as a control treatment agent. In order to achieve a better control effect, both The same additives, prepared as water emulsion.

[0043] Transplant the tobacco for testing. When transplanting, it is strictly forbidden to transplant the tobacco seedlings carrying diseases and insects into the field, especi...

Embodiment 3

[0050] This example provides a field test on the control effect of a functional agricultural composition containing triacontanol and polysaccharides on cucumber mosaic virus disease and cucumber powdery mildew. The cucumber variety is a self-fertile variety. The test site has medium fertility and the same management level. Double-row cultivation is adopted on high ridges and large and small rows.

[0051] As is well known to those skilled in the art, the symptoms of cucumber mosaic virus disease are as follows: the seedlings are infected, the cotyledons turn yellow and wither, and the young leaves present mosaic shapes of dark green and light green. The disease occurs in the adult plant stage. Symptoms first appear from the upper new leaves, and chlorotic spots appear, and later appear as mottled mottled leaves with dark green and alternate colors. The lower leaves of the diseased plants are gradually yellow and withered, the stems and internodes are shortened, and small leave...

Abstract

The invention provides a functional agricultural composition containing triacontanol and glycan, the functional agricultural composition comprises an effective component A and an effective component B, the component A is triacontanol, and the component B is one or a combination of two of chitosan and glucosan. Within a certain proportioning range, the composition has excellent prevention and treatment effects on tomato virus diseases, cucumber mosaic virus diseases, cucumber powdery mildew and tobacco mosaic virus diseases, and can promote the growth of crops and increase the yield.

Description

technical field [0001] The invention belongs to the technical field of agricultural compositions, and relates to a functional agricultural composition containing triacontanol and polysaccharides. Background technique [0002] Crop diseases are mainly divided into fungal diseases, bacterial diseases and viral diseases. Viruses are composed of protein capsids and the genetic material they wrap. They are a very special form of life. Plant viruses introduce their own genetic material into plant cells, causing abnormal metabolism of plants, leading to the occurrence of plant virus diseases. At present, chemical control still occupies a very important position in the comprehensive management of plant virus diseases. [0003] Triacontanol (triacontanol, TAL) is a natural long carbon chain plant growth regulator, a natural biological product purified and extracted from beeswax, which is harmless to humans and animals, has no side effects, and has no pollution to the environment. ...
