MANUAL- all divisions – Weed Identification & Control - 4-H 247-W

Division 1

1. Collect and identify 15 different weeds from the common and/or invasive plants of Indiana. Your collection of weeds must be taken from the list of common weeds in publication 4-H 247-W. Be aware that some weeds may be more prevalent at different times of the year. Each specimen should show flower and/or fruit, leaf, stem, and root characteristics, all of which are necessary for complete and accurate identification.

2. Press weeds (see page 4, 4-H 247-W).

3. Mount each individual weed on 8 1/2" x 11" poster board by either taping or gluing the plant to the poster board

4. Cover the poster board containing the plant specimen with cellophane or clear sheet plastic or put it in a plastic sheet protector. Place the pages in a three-ring binder (punch holes of adequate size to allow easy turning of the pages in the binder).

5. Label (label size, 1 1/2" x 2") each weed as to:

• Name of weed (common and scientific names-remember to italicize or underline scientific names)

• Where found (lawn, garden, pasture, etc.)

• How it reproduces (seed and/or underground root parts)

6. Answer questions on record sheet 4-H 247A-W, and put a copy of the record sheet in your notebook.

7. In year two, exhibit a different set of weeds, not repeating the ones from year one.

3. Place one tablespoon of the dried weed seeds in a plastic zippered bag.

4. Mount the plastic bags on poster board (22" x 28"). Mounting must be made to exhibit the poster in a horizontal position. Place your name, county, and club name in the lower right corner of the poster.

5. Label (label size, 1 1/2" x 2") each weed seed as to:

• Name of weed (common and scientific names--remember to italicize or underline scientific names)

• Where found (lawn, garden, pasture, etc.)

• Annual, biennial, or perennial.

6. Answer questions on record sheet 4-H 247C-W, and attach a copy of the record sheet to the back of your poster.
