marbled paper insecticide

A marbled-paper spray emulsion of insecticide creates a dot-halftone like pattern of insecticide on plant leaves.

This could create dose hotspots where a much higher than usual dose of an insecticide is consumed, causing a poison spike effect at the insects physiology.

This produces a more lethal at lower dose insecticide,even though the average amount of insecticide at the whole plant is the same as previous techniques or even a lower amount.

The poison spike effect could make some things which are not currently insecticides because their LD50 (lethality) effect is too low to become functional insecticides because of the much higher poison spike dose. That creates a wider range of possible insecticide chemicals that could be used, perhaps reducing chemical resistance.

This could be an effective use of pesticide spraying drones that are good at getting really near a plant. I think marbled splatter-dots from a traditional sprayer would aslo work.
