Spontaneously Formed Ratio-Tunable Micro- and Nano-Capsule Coexist System for Precision and on-Demand Fungicide Delivery in Crop Leave.

Multiscale particle size functional pesticide carriers can provide more efficient protection for plants, but this protection is difficult to achieve via single-scale formulation technology. This study presents a novel one-step method for the preparation of lignin-based micro/nanocapsules with controllable proportions within a unified system. This strategy enables the adjustment of the proportion of nanocapsules to between 18.

Fungicide smoke generated by electrical heating effectively controls gray mold of Chinese chives and reduces residue risk through adequate environmental sterilization.

Background: Labor-saving pesticide application technology is eagerly pursued in the planting system of Chinese chives. In this study, we developed a set of application approaches by turning fungicides into smoke to achieve this goal.

Results: The fungicides fludioxonil, fluopyram, boscalid, procymidone, and prochloraz could be vaporized into smoke at temperatures below 300 °C.
