true/false - it is required by law that pesticide application equipment to be calibrated. ✔✔True

Why should you use PPE when calibrating spray equipment? ✔✔Because the equipment may have pesticide residues on it.

Annuals ✔✔Die back each year when temperatures drop to freezing point

Perennials ✔✔Live indefinitely

Biennials ✔✔Completes life cycle in 2 years.

Year 1 - Taproot forms (vegetative)

Year 2 - Reproduces and dies

Summer annuals ✔✔Germinate in the spring, then flower and reproduce in late summer/early fall
