3 Corn Dent Stage Harvest Procedures WHEN TO HARVEST: 1. ONLY IF you are to complete item #8 on the corn B-Form. 2. If at least 3 of the 5 ears used to determine the maturity of the field are code 6 (Dent) or beyond. WHAT TO HARVEST: The first 5 ears that are at least code 6 (dent), starting with the 5 ears used to determine maturity. Continue harvesting ears, working in the direction away from the unit, until you have 5 ears code 6 or 7. REMEMBER: ONLY 5 EARS BEYOND THE ONE UNIT USED TO DETERMINE MATURITY ARE SENT TO THE LAB, NOT 5 EARS BEYOND BOTH UNITS. HOW TO HARVEST: 1. Completely shuck all 5 ears. 2. Place the 3rd and 4th ears in a cloth bag and place in a YELLOW Tyvek envelope. 3. Place the remaining 3 ears the same Tyvek envelope. 4. Complete the yellow corn ID card including the poid and sample number and check the code 6 box. Make sure the date on the ID card equals the date on the Form B 5. UPS this envelope to the National Lab using the label addressed to: St. Louis.

4 WHEN NOT TO HARVEST: 1. The corn may not be in dent stage during any of your monthly survey periods. In this case, you won t complete the dent stage harvest procedures. 2. The corn may be at the dent stage for more than one month (this is unlikely). If this happens only send item #8 (dent stage) ears to the lab the first time.

5 Form B Item # 13 Harvest Procedures WHEN TO HARVEST: If 3 or more ears are code 7 or the farmer will harvest the field within 3 days. WHAT TO HARVEST: All of the ears in row 1 of both units.

Place the 3rd and 4th ears in row 1 in a separate plastic plastic bag for each unit. It is much easier, especially for larger ears if the ears are placed in the bag so that the ears are parallel to the side of the bag. 6. Complete the yellow corn ID tag including the poid and sample number Be sure to put the date on the ID tag. It must be the same date as it is on the B form. 7.
