Contact pesticide

Surface-acting insecticide (e.g., contact pyrethroid).

Systemic pesticide

Plant-absorbed insecticide. Needs uptake window.

Contact fungicide

Surface fungicide (e.g., Mancozeb). Needs long dry window.

Systemic fungicide

Absorbed fungicide. More tolerant of humidity.

Herbicide

Weed killer. Needs uptake window and low drift.

Foliar fertilizer

Liquid nutrient via leaves. Cool + humid preferred.

Drone application

Aerial spray via drone. Tighter wind/gust limits due to fine droplets and downwash drift.
