Problems solved by technology

As we all know, the seedlings that have been unearthed generally have a strong ability to resist drought, but the seeds that have not germinated and exposed to the soil will easily lose water in case of drought, making the seeds invalid and reducing the seedling rate.

Embodiment 1

[0019] Example 1: Indoor Toxicity Determination of Metalaxyl, Cyclostrobin, Aminooligosaccharin and Compounds to Rice Blight

[0020] Test object: Rice blight (Rhizoctonia solani), collected from the field, separated and purified indoors.

[0021] Test method: After pre-testing to determine the effective inhibitory concentration range of each agent, metalaxyl, cyprostrobin, amino oligosaccharin and their mixed preparations were serially diluted to 5 concentrations according to the gradient of active ingredient content, and sterile water was used as the preparation method. control. Refer to the "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", and use the mycelium growth rate method to determine. Add different concentrations of medicines into sterilized petri dishes, 1mL per dish, then add 10mL of sterilized and melted PDA medium, mix thoroughly to form a plate, and then punch the expanded colony into a 0.8cm bacterial dish, 1 per dish The slices we...

Embodiment 2

[0031] Example 2: 2% Metalaxyl 5% Cyclostrobin 2% Aminooligosaccharin Suspension Seed Coating

[0032] The content of each component (by weight) is: metalaxyl technical 2%, cyclostrobin technical 5%, amino oligosaccharin 2%, agricultural milk 6022%, sodium dodecylbenzene sulfonate 5% , hydroquinone 2%, xanthan gum 0.5%, silicone oil 1%, urea 2%, basic rhodamine 0.6%, add water to make up to 100%. After mixing, grind in a sand mill for 3 to 4 hours, so that the particle size is all below 5 μm.

Embodiment 3

[0033] Example 3: 2% Metalaxyl 3% Cyclostrobin 2% Aminooligosaccharin Suspension Seed Coating

[0034] The content of each component (by weight) is: metalaxyl 2%, cyclostrobin 3%, aminooligosaccharin 2%, agricultural milk 6022%, sodium dodecylsulfonate 10% %, hydroquinone 2%, carboxymethyl cellulose 3%, n-octanol 1%, ethylene glycol 2%, basic rhodamine 0.5%, add water to make up to 100%. After mixing, grind in a sand mill for 3 to 4 hours, so that the particle size is all below 5 μm.

Abstract

The invention relates to a suspended seed coating agent capable of promoting germination and growth of seeds. The suspended seed coating agent is prepared from the following effective components in percent by weight: 1 to 3 percent of metalaxyl, 2 to 5 percent of JS399-19, and 1 to 2 percent of amino-oligosaccharin, wherein the weight ratio of metalaxyl to JS399-19 to amino-oligosaccharin is (1-3): (2-5): (1-2). The suspended seed coating agent has the effects of preventing and treating diseases and promoting germination and growth of the seeds to let the seeds come up out of the ground and be seedlings; the quality of plants in the seedling stage is improved, and the seedling rate of the seeds is increased; and the seed cost and the operation of filling the gaps with seedlings can be reduced favorably, and the aim of saving time and labor is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural medicaments, and in particular relates to a suspended seed coating agent capable of promoting seed germination and growth. Background technique [0002] Metalaxyl, the English name is metalaxyl, the chemical name is: D,L-N-(2,6-dimethylphenyl)-N-(2-methoxyacetyl)alanine methyl ester, is a kind of protective It is a systemic fungicide with therapeutic effect, which can be absorbed by roots, stems and leaves of plants, and transferred to various organs of plants with the movement of water in plants. Effective against diseases caused by mold, Phytophthora, and Pythium. [0003] Cyclostrobin is a new fungicide independently developed by Jiangsu Pesticide Research Institute Co., Ltd. The compound belongs to cyanoacrylates, is highly efficient, slightly toxic, broad-spectrum, low-residue, and environmentally friendly. It has protective and therapeutic effects on plant diseases caused by Fusarium,...
