Potato sprout inhibition suspended seed coating and preparation method thereof

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...

AI Technical Summary

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.
