Problems solved by technology

[0005] However, there is no report about preparing uniconazole into a suspension seed coating agent and using it as a seed potato sprout inhibitor
The main reason is that the concentration of uniconazole directly affects its effect on plants, and the concentration required for different plants to inhibit germinatio...

preparation example Construction

[0099] The preparation method of potato bud-suppressing suspension seed coating agent provided by the invention comprises the steps of: taking uniconazole, wetting dispersant, film-forming agent, thickener, antifreeze, additive, warning color, defoamer, preservative and Water, mixed and then sanded, sheared and filtered to obtain the product.

[0100] In production, the mass ratio of the potato bud-inhibiting suspended seed coating agent provided by the invention to the potato seed is 1: (100-200).

[0101] The potato bud-suppressing suspension seed coating agent provided by the invention comprises uniconazole, wetting dispersant, film-forming agent, thickener, antifreeze, additive, warning color, defoamer, antiseptic and water; Wherein, uniconazole The ratio of azole, wetting and dispersing agent, film forming agent, thickener, antifreeze, additive, warning color, defoamer and preservative is calculated by mass ratio: 10:(3~10):(1~5):( 0.1~1):(2~10):(1~5):(0.2~1.5):(0.1~1):(...

Embodiment 1

[0104] The preparation of embodiment 1 potato bud-suppressing suspension seed coating

[0105] Take 10kg uniconazole, 3kg Tween-80, 1kg polyethylene glycol, 0.1kg white carbon black, 2kg ethylene glycol, 1kg kaolin, 0.2kg scarlet, 0.1kg octanoic acid, 0.1kg sodium benzoate and 82.4kg water, mix , and then sand the mixed slurry in a sand mill to obtain a homogeneous material, and then put the homogeneous material into a high-shear mixing emulsifier and shear it to a particle size of 2 μm to 4 μm, and the particle size is less than 4 μm The amount is greater than 95%, and the material is discharged, that is to say.

Embodiment 2

[0106] The preparation of embodiment 2 potato sprout-suppressing suspension seed coating

[0107] Take 10kg uniconazole, 10kg agricultural milk 700#, 5kg sodium carboxymethylcellulose, 1kg xanthan gum, 10kg propylene glycol, 6kg diatomaceous earth, 1.5kg blue, 1kg Tween-20, 1.5kg formic acid and 55kg water, Mix, and then sand the mixed slurry in a sand mill to obtain a homogeneous material, and then put the homogeneous material into a high-shear mixing emulsifier and shear it to a particle size of 2 μm to 4 μm, and the particle size is less than 4 μm The amount of particles is greater than 95%, and the material is discharged.

Abstract

The invention belongs to the technical field of pesticide, and particularly relates to a potato sprout inhibition suspended seed coating and a preparation method of the potato sprout inhibition suspended seed coating. The potato sprout inhibition suspended seed coating comprises uniconazole, a wet dispersing agent, a film-forming agent, a thickening agent, an antifreezing agent, additive, warning color, a defoaming agent, preservative and water, wherein the mass ratio among the uniconazole, the wet dispersing agent, the film-forming agent, the thickening agent, the antifreezing agent, the additive, the warning color, the defoaming agent and the preservative is 10:(3-10):(1-5):(0.1-1):(2-10):(1-5):(0.2-1.5):(0.1-1):(0.2-1.5). The potato sprout inhibition suspended seed coating provided by the invention has good effect in the aspect of delaying potato sprout, can delay the germination of the axillary buds of potatoes, can inhibit the potato sprout before the potato seeds are planted, does not influence the emergence rate after the potato seeds are planted, and improves the seedling emergence effect after the potato seeds are planted.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a potato sprout-inhibiting suspended seed coating agent and a preparation method thereof. Background technique [0002] Potato, as the fourth largest food crop after rice, corn and wheat, has been paid more and more attention by people. Potatoes mainly use tubers for vegetative propagation, but the dormant period of potato tubers used as seed potatoes is usually short, and seed potatoes germinate during storage, and the young shoots are easily broken during transportation, resulting in lack of seedlings during field planting. ridge phenomenon. [0003] Existing anti-sprouting techniques mainly contain cellar storage, spraying anti-sprouting agents, soaking seeds and so on. Ventilation should be ensured during cellaring to reduce rot, so there must be enough space before it can be realized. Spraying sprout inhibitors does not require a lot of space, but uneven application ma...
