When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
1. It could be chlorotic, simply give it a shot of fertilizer to help.
2.Heat stress.
3.Too much water
4. Root rot (usually associated with too much water)
5. A little critter called a cut worm, it eats away at the base of the plant girdling it.
6. Round Up or other chemical damage. (Believe it or not I do see this at least once a week in the field)
7. Mulching to heavily at the base of the plant. This will allow moisture to start to rot away the stem of the plant.
Hope these help.
