Abiotic stresses
Caused by unfavorable growing conditions (drought, wind, flood)
Absorption
The movement of pesticides into plants and, to a lesser degree, soil
microorganisms.
Adjuvant/Additive
Substance added to a pesticide to improve its effectiveness, usability
or safety such as penetrants, spreader-stickers, storage stabilizers
and wetting agents.
adventitious roots
