Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a nano plant immunity-inducing and resistance-inducing seed coating agent and application thereof.
Background
The seed coating agent is a new pesticide formulation for coating the outside of seeds, and is a seed treatment agent which is processed by a special process together with auxiliaries such as film forming agents, dispersing agents and the like on the basis of some pesticides. After the seeds are treated by the seed coating agent, a layer of agent film is coated on the surfaces of the seeds, so that the health of the seeds can be better ensured for a long time. After the seeds treated by the seed coating agent are sown, part of the agent can be slowly released in the soil, and the other agent can enter the inside of the seeds, so that plant diseases and insect pests can be prevented and controlled for a long time.
The plant immunity inducer can induce plants to generate immune response and activate metabolic regulation, strengthen disease resistance and stress resistance of the plants, promote plant growth and finally achieve the aim of increasing yield. The commonly used plant immunity inducer is sprayed after the seeds germinate, and the effect is not ideal. The reason is that the utilization rate is not always up, and the leaves, the stem bark and the like of the plants can influence the absorption of the plant immune elicitor.
CN104904749a discloses a plant immune elicitor and its application, the immune elicitor comprises the following active ingredients by weight percent: 0.001-0.02% of amino-oligosaccharin and 0.01-0.2% of phosphite; the amino oligosaccharin and phosphite are combined, the mixing proportion of the components of the obtained immunity inducer is reasonable, and the immunity inducer is applied to corn, so that the immunity inducer has good control effect on small spot disease, can improve the yield of corn, and realizes the synchronization of corn powder scattering and spinning.
CN110063364a provides a plant immunity inducer and its application, the effective components of the plant immunity inducer include 2 amino 3,5 dichlorobenzoic acid, sulfachloropyridazine and chitosan. The occurrence of the immunological blue mold of the picked citrus can be induced, the damage effect of the blue mold to the quality of the picked citrus is effectively inhibited, and the preservative period of the picked citrus is prolonged; the plant immunity inducer is nontoxic and pollution-free, can directly act on the harvested citrus, and has no pesticide residue; can also effectively prevent and treat mango anthracnose after picking.
In order to solve the problem, the invention mixes the plant immunity inducing and resisting agent and seed coating agent for the first time, and the plant immunity inducing and resisting agent is treated at the beginning of the seed stage, thus greatly increasing the plant immunity inducing and resisting effect.

Detailed Description
The following description of the present invention will be made clearly and fully, and it is apparent that the embodiments described are some, but not all, of the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a nano plant immunity-inducing agent seed coating agent, which is prepared from the following raw materials: plant immunity inducer, film forming agent, wetting agent, dispersing agent, penetrating agent, thickening agent and other auxiliary agents.
Plant immunity inducer
The plant immunity inducer can be selected from exogenous proteins, saccharides, organic acids and the like, and the plant immunity inducer is the saccharide plant immunity inducer in the invention.
Preferably, the saccharide plant immunity inducer is selected from one of oligosaccharin, amino oligosaccharin, lentinan and chitosan.
More preferably, the saccharide plant immunity-inducing agent is a compound of amino-oligosaccharin and chitosan, and the compound ratio is 2:1.
Film forming agent
The film forming agent has the main function of ensuring that a film is formed on the surface of the seeds, and forming a protective and stimulated film layer for the seeds.
In the invention, the film forming agent is one or more selected from xanthan gum, carboxypropyl cellulose, polyvinyl alcohol, chitosan and polyethylene glycol.
Preferably, the film forming agent is a mixture of polyvinyl alcohol and chitosan, and the mixing mass ratio is 1:1.
As a preferred mode of the present invention, the film forming agent further comprises an N, N-dimethylethylaldehyde alkylamine complex solution; its cas number is: 124330-23-0. More preferably, the film former further comprises nanosilica.
Wetting agent
In the invention, the wetting agent is selected from sodium lauryl sulfate, sodium dodecyl benzene sulfonate and sulfosuccinate; sodium lauryl sulfate is more preferred.
Dispersing agent
The dispersing agent in the invention is selected to be a liquid dispersing agent at normal temperature, and ethanol is preferable.
Penetrant
In the invention, the penetrating agent is carbonized fiber.
Thickening agent
In the invention, the thickener is magnesium aluminum silicate.
Other auxiliary agents
In the present invention, the other auxiliary agent is selected from a disintegrating agent or a binder.
Wherein the disintegrating agent is cross-linked polyvinylpyrrolidone; the binder is sodium alginate.
The preparation process comprises the following steps:
The invention provides a preparation method of the seed coating agent, which comprises the following steps: stirring and mixing the plant immunity inducer, the penetrating agent, the thickening agent and other auxiliary agents, adding the film forming agent into the mixture for ball milling and mixing, and then spraying and mixing the mixed liquid of the dispersing agent and the wetting agent in the stirring process.
The invention also provides application of the nano plant immunity-inducing agent seed coating agent in rice.
Explanation of the mechanism: the nano plant immunity induction agent seed coating agent provided by the application combines the plant immunity induction agent and the seed coating agent for the first time, so that not only can a better coating effect and a plant immunity induction effect be realized; meanwhile, the present inventors have found that since the plant immunity inducer needs to stimulate the surface protein, it is often required to have an excellent permeation effect; and nano-materials or metals are also considered as auxiliary materials. Research shows that when metal ions are adopted as plant immunity elicitor for treatment, the concentration requirement is often too high; too low a concentration does not achieve the osmotic effect, and too high a concentration may cause drought stress higher than salinity stress, and the germination of seeds is completely inhibited, not to mention the immune induction effect. According to the application, the N, N-dimethylethylaldehyde amine complex solution and the nano silicon dioxide material are matched, so that a good drought stress effect can be generated; meanwhile, the requirement on the concentration range is not very strict; the reason is probably because the N, N-dimethylethylaldehyde amine complex solution can react with chitosan in the application, so that crosslinking is realized, a better film layer is formed, and the seed germination rate is high; and simultaneously, the generated superfluous Al ions can act with nano silicon dioxide to generate better plant immunity induction effect. Meanwhile, the formula adopted by the application does not need to be additionally added with an antifreeze agent, and the preparation method provided by the application is matched, so that the seed coating agent provided by the application has the advantages of uniform coating, uniform film layer, ventilation, high germination rate, easiness in storage and good product stability.
The invention is further illustrated with reference to specific embodiments.
Example 1: the embodiment provides a nano plant immunity-inducing agent seed coating agent, which is prepared from the following raw materials in parts by weight: 20 parts of plant immunity inducer, 1.5 parts of film forming agent, 4 parts of wetting agent, 2 parts of dispersing agent, 1 part of penetrating agent, 0.5 part of thickening agent, 0.03 part of disintegrating agent and 0.5 part of binding agent.
Wherein the plant immunity inducer is the compound of amino-oligosaccharin and chitosan, and the compound ratio is 2:1.
