Abstract

The invention belongs to the field of preparations of DCPTA, and particularly relates to an ultra-low volume spray liquid containing DCPTA and an application of the ultra-low volume spray liquid containing DCPTA. The ultralow-volume spray liquid containing the DCPTA is prepared from the following components in percentage by mass: 0.8 to 10 percent of the DCPTA, 0 to 10 percent of pesticide active ingredients, 2 to 15 percent of a surfactant, 0.5 to 2 percent of a synergist and the balance of an anti-transpiration agent. The anti-transpiration agent is selected from one or a combination of two or more than three of terpilenol, isoeicosane, second-line oil, acetophenone, corn oil, rapeseed oil, methyl oleate and ethyl oleate; the synergist is selected from one or a combination of two or more than three of synergistic phosphorus, piperonyl butoxide, azone and thiazone. The ultra-low volume spraying liquid is a special pesticide preparation for ultra-low volume spraying. The viscosity is 200-600cp, the low-temperature and heat storage stability is good, the volatility is proper, the medicament concentration is high, and the lasting period is long.

Description

technical field [0001] The invention belongs to the field of production-increasing amine preparations, and in particular relates to an ultra-low-capacity spray liquid containing production-increasing amine and its application. Background technique [0002] Yield amine is a plant growth regulator first discovered by Yokoyama, a researcher at the U.S. Department of Agriculture's Fruit and Vegetable Chemistry Research Institute in the 1970s. The chemical name is 2-(3,4-dichlorophenoxy)ethyldiethylamine, and the structural formula is shown in the following formula, abbreviated as DCPTA. [0003] [0004] Increased production of amine crude oil is yellow to brown viscous liquid with grassy smell, its hydrochloride and citrate are white powdery solids, soluble in water, soluble in methanol, ethanol and other organic solvents, stored under normal conditions Stablize. Stable under neutral and acidic conditions, easy to decompose under alkaline conditions. Yield-increasing amin...
