The invention belongs to the technical field of ultra-
low volume liquid, and particularly relates to ultra-
low volume liquid for preventing and treating
spodoptera frugiperda. The ultra-
low volume liquid for preventing and treating the
spodoptera frugiperda is prepared from the following components in percentage by
mass: 8 to 20 percent of an
active component, 0.5 to 1.5 percent of a synergist, 5 to 8 percent of a cosolvent, 3 to 5 percent of a penetrating agent, 2 to 3 percent of a dispersing agent, 0.5 to 1 percent of an
antioxidant, 0.3 to 0.5 percent of an anti-drifting agent and the balance of a
solvent, wherein the
active ingredient is prepared by compounding
abamectin and
lufenuron. The synergist of the ultra-low volume liquid can enhance the
toxicity effect of the compound combination, and is beneficial to further improving the
control effect on target pests. In addition, compared with a single penetrant, the penetrant of the ultra-low volume liquid can improve the
wetting, spreading and infiltration capacities of the agent, so that the
utilization rate of effective components of pesticides is improved, the
pesticide dosage is reduced, and the environmental
pollution and the prevention and treatment cost are reduced.
