Embodiment 1
[0031] The coating agent is modified chitosan, which is made by the following methods:
[0032] S1. Add 1g of carboxymethyl chitosan and 100g of glacial acetic acid into a three-necked flask with a stirrer and a thermometer, and replace the air with nitrogen. Under the protection of nitrogen, stir at room temperature until the carboxymethyl chitosan is completely dissolved. Finally, 0.5 g of isopropanol solution containing N-hydroxysuccinimide and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide was added dropwise, stirred at room temperature for 1 h, and then Add 120 mL of isopropanol solution of 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane dropwise, and continue stirring at room temperature for 2 h after the addition is complete , and then the reaction mixture is filtered, and the filter cake is washed with deionized water, suction filtered, the filter cake is taken, and freeze-dried to obtain intermediate 1, which contains N-hydroxysuccinimide and 1-(3- N-hydroxysucci...
Embodiment 2
[0035] The coating agent is modified chitosan, which is made by the following methods:
[0036] S1. Add 10g of carboxymethyl chitosan and 300g of glacial acetic acid into a three-necked flask with a stirrer and a thermometer, and replace the air with nitrogen. Under the protection of nitrogen, stir at room temperature until the carboxymethyl chitosan is completely dissolved. Finally, 1.5 g of isopropanol solution containing N-hydroxysuccinimide and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide was added dropwise, stirred at room temperature for 1 h, and then Add 150 mL of isopropanol solution of 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane dropwise, and continue stirring at room temperature for 2 h after the addition is complete , and then the reaction mixture is filtered, and the filter cake is washed with deionized water, suction filtered, the filter cake is taken, and freeze-dried to obtain intermediate 1, which contains N-hydroxysuccinimide and 1-(3- N-hydroxysucc...
Embodiment 3
[0039] A pesticide composition comprising prothioconazole, thiamethoxam and tetrachlorantraniliprole, the pesticide formulation made of it is a suspension seed coating, and the raw materials and their weight percentages are shown in Table 1.
[0040] Table 1
[0041]
[0042] Preparation method: Add the auxiliary additives in parts by weight in the above table into deionized water, after high-speed shearing and mixing evenly, then add the active ingredients in parts by weight in the above table, coating agent, and film-forming agent in turn, and put them in a ball mill Grinding the balls for 2 hours, so that the particle diameter is below 5mm, the suspension seed coating agent of the present invention can be made, wherein the added quality of deionized water is 3 times of the amount of auxiliary additives added.
