- May damage plants
- High concentrations increase exposure risk
- Often absorbed easily through the skin
Flowable or suspension
Solid particles of an active ingredient are suspended in liquid
Flowable or suspension use

- Spray mix needs constant agitation
Microcapsule suspension
Small capsules of active ingredients are suspended in a liquid.
Microcapsule suspension use
Variety of uses, suitable when gradual delivery is needed
Microcapsule suspension pros
- Safer from lower exposure risk
- Slow release prolongs effectiveness
- Reduces injury to plants
Microcapsule suspension cons
- Slow breakdown may leave pesticide in place at time of harvest
- Bees may carry capsules to the hive
- Visible residue
