Problems solved by technology

The half-life of paclobutrazol in the soil is as long as 0.5-1 year, it is not easy to decompose, and it is easy to cause accumulation in the soil and affect the growth of subsequent crops
[0006] Most of the plant growth regulators containing paclobutrazol on the market are wettable powders or suspension concentrates, which have the problems of low suspension rate and complicated process in the preparation process.

Abstract

The invention provides microemulsion containing trinexapac-ethyl and paclobutrazol. The microemulsion is prepared from components in percentage by weight as follows: 1%-40% of trinexapac-ethyl, 1%-10% of paclobutrazol, 1%-20% of a solvent, 1%-15% of a cosolvent, 10%-50% of an emulsifier, 1%-10% of an antifreezing agent and the balance of water. The microemulsion containing trinexapac-ethyl and paclobutrazol has excellent lodging-resistant and lawn-dwarfing effects as well as low use cost, little environmental pollution and good environmental protection effect.

Description

[0001] Technical field: [0002] The invention belongs to the field of plant growth regulators, and in particular relates to a microemulsion containing trinexapac-ethyl and paclobutrazol mainly used in lodging resistance of wheat and rice and lawn dwarfing. [0003] Background technique: [0004] Trinexapac-ethyl is a cyclohexane carboxylic acid plant growth regulator, which regulates plant growth by inhibiting the biosynthesis of gibberellin. Used in cereal crops and winter rapeseed to prevent lodging and improve harvest efficiency; used in turf to reduce the frequency of mowing; used in sugarcane to promote ripening. Due to the low melting point of the original medicine of trinexapac-ethyl, the current main dosage forms are emulsifiable concentrates and microemulsions containing only a single trinexapac-ethyl component, and there is no composition dosage form containing trinexapac-ethyl. The half-life of trinexapac-ethyl in soil is less than 7 days, and the main metabolite i...
