pesticide formulation
2. the material (usually water or oil) used to dilute the formulated product for application
✔✔Causal Organisms - ✔✔The organism (pathogen) that produces a given disease
, ✔✔Chemical Control - ✔✔A pest management strategy that involves the use of
naturally derived or synthetic chemicals that kill, attract, repel, or otherwise control the
growth of pest plants, animals, and microorganisms
EX Avicides, insecticides, rodenticides
✔✔Chemical Degradation - ✔✔the breakdown of a pesticide by process not involving a
living organism
