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 germination is also different. If the appropriate concentration cannot be selected, it may produce a germination-promoting effect
Moreover, the solubility of uniconazole in water is very low. If it is prepared as a suspension seed coating agent, it is necessary to screen the auxiliaries and adjust the proportion of each component.

[0099] The preparation method of potato sprout inhibitor suspension seed coating agent provided by the present invention includes the following steps: taking uniconazole, wetting and dispersing agent, film forming agent, thickening agent, antifreeze, additives, warning color, defoaming agent, preservative and After mixing, the water is sanded, cut, and filtered to obtain it.

[0100] During production, the mass ratio of the potato sprout suppressing suspension seed coating agent provided by the present invention to the potato seed potato is 1: (100-200).

[0101] The potato sprout inhibiting suspension seed coating agent provided by the present invention includes uniconazole, wetting and dispersing agent, film-forming agent, thickening agent, antifreeze, additives, warning color, defoaming agent, preservative and water; The ratio of azole, wetting and dispersing agent, film-forming agent, thickener, antifreeze, additives, warning color, defoamer and preservative is calculated by ma...

Embodiment 1

[0104] Example 1 Preparation of Potato Sprouting Suspension Seed Coating Agent

[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 caprylic acid, 0.1kg sodium benzoate and 82.4kg water and 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 to particles with a particle size of 2μm~4μm and a particle size of less than 4μm If the amount is greater than 95%, the material is ready to be obtained.

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 suspension seed coating agent and a preparation method thereof. Background technique [0002] As the fourth largest food crop after rice, corn and wheat, potato has attracted more and more attention. Potatoes mainly use tubers for vegetative propagation, but the dormancy period of potato tubers used as seed potatoes is usually short. Seed potatoes germinate during storage, and young shoots are easily broken during transportation, resulting in lack of seedlings during field planting. The phenomenon of ridges. [0003] The existing sprout suppression technologies mainly include cellaring, spraying sprout inhibitors, and soaking seeds. Ventilation and ventilation must be ensured when cellaring to reduce decay, so enough space must be available. Spraying the sprout inhibitor does not require a lot of space, but the problem of uneven application may occur, an...
