When shopping for the melons, look for a clean, dish-shaped scar and a pleasant, musky aroma at room temperature.
1. For the tendril that attaches at the same point as the melon to dry and turn brown. On some varieties this will need to be completely dried before the watermelon is ripe, and on others it will only need to be in the process of turning brown.
2. The surface develops a surface roughness near the base.
3. A yellow coloration on the area of the melon that has contact with the ground.
Controlling the budworm is difficult, Upham says. If you have small plantings, you can try hand-picking at dusk. For larger plantings, look for products with synthetic pyrethroid active ingredients such as permethrin, esfenvalerate, cyfluthrin, bifenthrin, lambda-cyhalothrin or related compounds, or spinosad (Borer, Bagworm, Leafminer and Tent Caterpillar Spray; Captain Jack's Dead Bug Brew).
Severe winters can be a natural form of control from one year to the next, Upham says. Temperatures below 20 will kill overwintering pupa, while areanext to heated buildings may allow them to survive.
