One of the major plant groups, known as dicots, with net veined leaves usually broader than grasses. Seedlings have two seed leaves (cotyledons); broadleaves include many herbaceous plants, shrubs, and trees. |
|
|
Buffer |
An adjuvant that lowers the pH of a spray solution and, depending on its concentration, can maintain the pH within the narrow range even if acidic or alkaline materials are added to the solution |
|
|
Buffer area |
A part of the pest infested area that is not treated with pesticide to protect adjoining areas from pesticide hazards. |
|
|
Calibration |
The process used to measure the output of a pesticide application equipment so that the proper amount of pesticide can be applied to a given area. |

|
|
Carrier |
The liquid or powdered inert substance that is combined with active ingredients in a pesticide formulation. May also apply to the water boils at a pesticide is mixed with prior to application. |
|
|
Cationic |
Pertaining to materials that contain positively charged ions. Some server factions include cat ionic materials to improve mixing and absorption by the Target pest. |
