A germination promoter is provided, which contains 2-chloroethanol and a thickener. Therefore, the physical state of the germination promoter is a paste, which is greatly different from the currently used thin liquid germination promoter in appearance. Accordingly, the germination promoter of this invention can easily be distinguished from wine, alcohol or any other drinkable liquid therefore, the possibility of drinking the germination promoter accidentally can be reduced. Even if the germination promoter is drunk by accident, people would spit the germination promoter due to the fluidity different from drinkable liquid. Thus, the germination promoter has a warning effect. In addition, due to the thickener, the staying time on a plant of the pasted germination promoter is extended and thus the possibility of the germination promoter dripping off a plant can be reduced. As a result, the possibility of touching the germination promoter dripping off a plant is reduced. Furthermore, a good germination effect can be reached by a small amount of the germination promoter, and thus the farmers’ planting cost is reduced.本發明提供一種催芽劑,其係包括2-氯乙醇(2-chloroethanol)以及一增稠劑。本發明之催芽劑具有增稠劑,故該催芽劑係為膏狀,明顯有別於現有技術之液狀的催芽劑,故提高與酒精等其他飲用液體的識別度,因此降低農民放入家中而導致誤食中毒的機率,即使誤食該催芽劑,仍可因其膏狀的流動感與液體不同而馬上區分故馬上吐出,因此具有警示農民的效果。此外,因該催芽劑呈膏狀,故增加了催芽劑停留在植物的分枝上的時間,不會隨易滴落,只需塗抹少量即可達到催芽效果,因而降低了農民種植植物的成本,更降低了農民接觸滴落的催芽劑之機率。
