Problems solved by technology

[0007] As we all know, the seedlings that have been unearthed are more resistant to drought, and the seedlings that have not been exposed to the soil will easily lose water in case of drought, causing the seeds to dry up and die, and the seedling rate will decrease

Embodiment 1

[0019] Example 1: Indoor Toxicity Determination of Thiram, Cyclostrobin, Aminooligosaccharin and Mixtures 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, dilute thiram, cyclostrobin, amino oligosaccharin and their mixed preparations to 5 concentrations in series according to the gradient of active ingredient content, and use sterile water as a 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 were repeated 4 times for each treatment...

Embodiment 2

[0031] Example 2: 5% thiram · 3% cyclostrobin · 2% aminooligosaccharin suspension seed coating

[0032] The content of each component (by weight) is: thiram 5%, cyclostrobin 3%, amino oligosaccharin 2%, agricultural milk 6022%, sodium lignosulfonate 5%, quinone 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 3-4 hours, so that the particle size is all below 5 μm.

Embodiment 3

[0033] Example 3: 6% thiram · 5% cyclostrobin · 2% aminooligosaccharin suspension seed coating

[0034] The content of each component (by weight) is: thiram 6%, cyprostrobin 5%, amino oligosaccharin 2%, Nongru 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 3-4 hours, so that the particle size is all below 5 μm.

Abstract

The invention relates to a suspended seed coating for early sprouting of seeds. The suspended seed coating comprises 5%-10% of thiram, 2%-5% of phenamacril and 1%-2% of amino-oligosaccharin, wherein the weight ratio of thiram to phenamacril to amino-oligosaccharin is (5-10):(2-5):(1-2). The suspended seed coating provided by the invention has an effect of preventing and treating diseases, can make the seeds early sprout, is beneficial to increasing of the seedling percent of the seeds and can improve the quality of plants in the seedling stage, so that the purposes of reducing seed cost, relieving operation of filling gaps with seedlings and saving time and labor can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural medicaments, and in particular relates to a suspension seed coating agent which can make seeds emerge early. Background technique [0002] Thiram, the English name is Thiram, the chemical name is: tetramethyl thiuram disulfide, is a broad-spectrum protective fungicide, against a variety of crop downy mildew, blight, anthracnose, cereal smut , Seedling yellow blight has better control. It is used for seedbed soil treatment and seed dressing, and can effectively prevent vegetable blight, damping-off, root rot, rice blast, flax leaf spot, rice seedling blight, rice bakanae, etc. disease. [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...
