Abstract
The invention discloses a pesticide ultra-low volume liquid and a preparation method and application thereof, wherein the pesticide ultra-low volume liquid comprises the following components in percentage by weight: 5-30% of ethephon, 0.1-1% of active component II, 4-20% of surfactant, 6-30% of cosolvent, 15% of antifreeze agent and the balance of alcohol ether solvent. The ethephon and the active component are effective components, and the surfactant is added after the ethephon and the active component are compounded, so that the spray breaking length can be increased, the grain diameter is increased, the drift is reduced, the dynamic surface tension of liquid drops is reduced, the spreadability of the liquid drops on the liquid level is increased, the rebound of the liquid drops on the leaf surface is reduced, the cosolvent can promote the absorption of the effective components, the antifreeze agent can increase the system density, the liquid medicine evaporation is reduced, and all the components supplement each other, so that the prepared preparation can be applied effectively in ultra-low capacity.
Description
Technical Field
