Abstract

The invention discloses an ultra-low volume liquid containing silafluofen and an organophosphorus insecticide, belonging to the field of pesticides. The ultra-low volume liquid comprises the silafluofen and an active constituent (II), which are compounded into an active constituent, and the balance of a surfactant and a solvent; and the active constituent (II) is selected from any one of fenitrothion phosphorus, quinalphos, triazophos, diazinon, phoxim, fenitrothion, profenofos, chlorpyrifos, malathion, and isocarbophos. The ultra-low volume liquid disclosed by the invention is convenient to process, low in cost, good in pesticide effect, long in lasting period, high in coordinated synergism and capable of saving water, and can be used to reduce environment pollution, improve the utilization ratio and application amount of the pesticide.

Description

technical field [0001] The present invention relates to the field of pesticides, in particular to an ultra-low-capacity liquid formulation of fluorine-containing permethrin and organophosphorus insecticides, which is effective against crop pests mainly through ultra-low-capacity spraying, low-capacity spraying or ultra-low-capacity electrostatic spraying. Prevention and treatment. Background technique [0002] At present, for the control of pests that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or the compounding of existing pesticide varieties. The former is due to the high development cost and long cycle required. And the current development speed is far behind the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different action mechanisms. If the ratio is reasonable, it can produce a significant synergistic effect, making th...
