Problems solved by technology

Seed treatment is an important means of preventing and controlling seedling pests and diseases. However, there are some problems in the seed treatment agents currently used in production: for example, Haoniandong and Ruijinte have single functions, while Likexiu, Shileshi, and Seed Dressing Shuang only have disease prevention effect, and the use technology is complicated, and it is not safe for crops; in the patent application document with application number 98106559.7, a series of seed coating agents are disclosed, and the seed coating agents are suitable for wheat and corn seeds. It is diniconazole, and the insecticide is one or any combination of carbofuran, phorate, acephate, phoxim, methylthiophen and isofenphos-methyl, and is suitable for The bactericide of the cotton seed coating agent is a combination of carbendazim, triadimefon, triadimenol, etc. Although the seed coating agent has insecticidal effects, one of its combinations can only be used for wheat and corn seeds. The other can only be used for cotton seeds, but cannot be used as a seed coating agent for various crop seeds at the same time

Embodiment 1

[0015] Embodiment 1: take by weighing 5 kilograms of fludioxonil, 5 kilograms of isofenifox-methyl former drug, 90 kilograms of auxiliary agent, the stabilizing agent in the auxiliary agent adopts 2,6-di-tert-butyl-p-cresol, its consumption The film-forming agent is polyvinyl alcohol, and its dosage is also 1 kg. The adhesive is sodium methylcellulose, and its dosage is 5 kg. The defoamer is 1 kg of foam enemy, and 1 kg of rhodamine is used as a warning color. , and then add 81 kg of water, mix them evenly, and adjust the pH value to 6.5, which is a seed coating agent containing 10% of the original drug of fludioxonil and isofenifox-methyl.

[0016] The method of use is: add 20 kg of water to 1 kg of seed coating agent, and then dress the seeds at a ratio of 600 kg of wheat seeds; the specific operation method is: according to the weight of the seeds to be dressed, weigh the prepared seed coat Mix the two with water and mix them evenly, then pour the seeds into it, stir them e...

Embodiment 2

[0017] Embodiment 2: take by weighing 4 kilograms of fludioxonil, 26 kilograms of the former medicine of isofenphos-methyl, and 70 kilograms of auxiliary agent, the stabilizing agent in the auxiliary agent adopts 2,6-di-tert-butyl-p-cresol, its consumption For 10 kg, the film-forming agent is selected from dextrin, and its consumption is also 10 kg. The adhesive adopts soluble starch, and its consumption is 20 kg. Kg of water, after mixing them evenly, adjust its pH value to 7, which is the finished product of seed coating containing 30% of the original drug of fludioxonil and isofenifox-methyl.

[0018] The method of use is as follows: add 18 kg of water to 1 kg of seed coating agent, and dress 500 kg of wheat seeds; the specific operation method is the same as in Example 1.

Embodiment 3

[0019] Embodiment 3: take by weighing 1 kilogram of fludioxonil, 28 kilograms of isofenifron-methyl former medicine, 71 kilograms of auxiliary agent, the stabilizing agent in the auxiliary agent adopts 2,6-di-tert-butyl-p-cresol, its consumption 1 kg, the film-forming agent is dextrin, and its dosage is 2 kg, the adhesive is soluble starch, and its dosage is 5 kg, the defoamer is 1 kg of foam enemy, and 1 kg of rhodamine is used as a warning color, and then 61 kg After mixing them evenly, adjust the pH value to 6.5 to obtain the finished seed coating agent.

[0020] The method of use is: add 19 kg of water to 1 kg of seed coating agent, and dress 550 kg of wheat seeds; the specific operation method is the same as in Example 1.

Abstract

The present invention relates to a new-type pests-killing and disease-preventing seed-dressing agent. Its composition includes fludioxonil, isofenphos-methyl raw medicine and adjuvant. Its pH value is 6.5-7, in said seed-dressing agent the plant growth regulator sodium nitriphenolate also can be added. Said invention is application to wheat, corn, cotton and peanut. Besides, said invention also provides its concrete application method.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a seed coating agent suitable for wheat, corn, cotton and peanuts. Background technique: [0002] Various crop seedling pests and diseases (such as wheat sheath blight, corn seedling blight, cotton seedling root disease, peanut stem rot, etc., underground pests such as grubs, needleworms, and mole crickets) have always been important problems in agricultural production. It often causes lack of seedlings and broken ridges and a large number of dead seedlings, which has a great impact on crop yield. Seed treatment is an important means of preventing and controlling seedling pests and diseases. However, there are some problems in the seed treatment agents currently used in production: for example, Haoniandong and Ruijinte have single functions, while Likexiu, Shileshi, and Seed Dressing Shuang only have disease prevention effect, and the use technology is complicated, and it is not safe for ...
