Abstract

The invention belongs to the field of chemistry, and particularly relates to a triazole derivative and application of the derivative in plant growth regulation and bactericide. The triazole derivative is a compound as shown in a general formula I defined in the description, a diastereoisomer, a chiral isomer or a salt thereof. The definition of each substituent group in the formula is shown in the description. The compound provided by the invention can be applied to plant growth regulation and bactericides.

Description

technical field [0001] The invention belongs to the field of chemistry, specifically a triazole derivative and the application of the derivative in plant growth regulation and fungicide. Background technique [0002] Paclobutrazol is a plant growth regulator, which has the effects of delaying plant growth, inhibiting stem elongation, shortening internodes, promoting plant tillering, increasing plant stress resistance, and increasing yield. However, due to its long residual period (pesticide electronic manual, the soil half-life is 0.5-1.0 years), it is easy to cause phytotoxicity to the next crops, resulting in no seedlings, late emergence, low emergence rate, deformed seedlings and other phytotoxicity. [0003] The development of plant growth regulators with fast metabolism and low residue is of great significance to agricultural production. Contents of the invention [0004] The object of the present invention is a triazole derivative and its application. [0005] In o...
