Problems solved by technology

[0003] At present, there are many kinds of seed coating agents popularized and used in China, but most of them have some problems, such as Li Kexiu, Shileshi, and Dividan have single functions, only have disease prevention effect, complex use technology, and poor safety for crops; they can effectively control underground pests Products such as phorate and methylthion are highly toxic

Embodiment 1

[0023] Example 1: 6% fluopyram·fipronil suspension seed coating agent (6% is the sum of the mass fractions of fluopyram and fipronil), calculated by weight percentage, including the following components:

[0024] Fluopyram 1.0%, Fipronil 5.0%, Sodium Lauryl Sulfate 3.0%, Sodium Lignosulfonate 6.0%, Ethylene Glycol 4.0%, Water Rose Red 2.0%, Xanthan Gum 0.2%, Oxymetholone Base cellulose 2.0%, polydimethylsiloxane 0.3%, sodium benzoate 0.3%, distilled water make up 100%.

[0025] The preparation process is as follows: mix quantitative fluopyram and fipronil original drug with sodium lauryl sulfate, sodium lignosulfonate, ethylene glycol, water-based rose red, xanthan gum, hydroxymethyl cellulose, poly Put dimethylsiloxane, sodium benzoate and water into the shearing kettle, turn on the high-shear emulsifier, make the shearing and mixing evenly, and then grind 1-2 times with a sand mill until the particle size of the suspension is fine. reach D 50 2~3μmD 90<5μm, the finished p...

Embodiment 2

[0026] Example 2 15% fluopyram·fipronil suspension seed coating agent, calculated by weight percentage, includes the following components:

[0027] Fluopyram 3.0%, Fipronil 12.0%, Sodium Dodecyl Benzene Sulfonate 3.0%, Nonylphenol Polyoxyethylene Ether 6.0%, Propylene Glycol 4.0%, Basic Rhodamine 2.0%, Magnesium Aluminum Silicate 0.5%, polyvinylpyrrolidone 2.0%, polydimethylsiloxane 0.3%, 1,2-benzothiazolin-3-one 0.3%, distilled water to make up 100%

[0028] The preparation method is the same as in Example 1.

Embodiment 3

[0029] Example 3 20% fluopyram·fipronil suspension seed coating is calculated by weight percentage and includes the following components:

[0030] Fluopyram 4.0%, Fipronil 16.0%, Sodium Lauryl Sulfate 3.0%, Calcium Lignosulfonate 6.0%, Glycerol 2.0%, Acid Scarlet 2.0%, Magnesium Aluminum Silicate 0.5%, Hydroxymethyl Sodium cellulose 2.0%, polydimethylsiloxane 0.3%, 1,2-benzothiazolin-3-one 0.3%, distilled water to make up 100%.

[0031] The preparation method is the same as in Example 1.

Abstract

The invention relates to the field of pesticide preparations and discloses a pest-killing disease-prevention suspended seed coating. The suspended seed coating comprises the following components in percentage by weight: 5.0-40% of fluopicolide, 1.0-20% of fipronil, 2.0-8.0% of wetting dispersant, 0.5-4.0% of film former, 1.0-4.0% of pesticide warning colouration dye, 0.1-2.0% of tackifier, 1.0-5.0% of antifreezer, 0.1-1.0% of preservative, 0.1-0.8% of foamer and the balance of distilled water. Compared with single fluopicolide or fipronil, the pest-killing and disease-prevention effect is remarkably improved, the seed germination rate can be also increased at the same time, and the seed germination rate of a coated seed can be increased by 5-8% in comparison with that of an uncoated seed. The suspended seed coating is convenient to use and can be mechanically or manually mixed with the seed to meet the demands of different users at the same time.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a suspension seed coating agent for killing insects and preventing diseases. Background technique [0002] In terms of production, due to bacteria on the surface or inside of the seeds, bacteria in the soil, or pests, rodents, and birds in the soil, or due to soil deficiencies, after seed sowing, there are often lack of nests, weak seedlings, and insect pests caused by seedlings. The phenomenon of lack of plants causes great harm to production, especially the harm caused by quarantine pests carried by seeds is even greater. For this reason, people have summed up many seed treatment technologies in production practice, and the application of seed soaking and seed dressing technology has played a very good role in controlling seedling pests and diseases, but due to the single effect of seed soaking and seed dressing, the efficacy period Short, easy to fall off the agent and c...
