We passed by a roadside home that for years sold vegetables. They are now selling flowers instead. The house is about 5 miles south of ours. There's not much reason for us to go that way as it is mostly farming country. Every field growing had corn in it or weeds. This area used to grow cotton. There was a cotton mill in the small town to our south. I often wondered why all the local farmers quit growing cotton.
I just looked up Texas plant diseases for Cotton
http://plantdiseasehandbook.tamu.edu...cialty/cotton/ A lot of things can effect cotton including RKN and Fusarium.
So I looked up Texas plant diseases for Corn
http://plantdiseasehandbook.tamu.edu...al-crops/corn/ Again a lot of things effect corn including Nematodes, but with one mention about Fusarium.
"
Ear and Kernel Rots (fungi – several species): Corn ear and kernel rots are a greater problem in areas with high rain fall from silking to harvest. Symptoms range from pink mold on ears with Fusarium to green mold with Tricoderma."
To me, that says that corn has a better chance of producing a sellable crop than cotton does.
I'm not interested in growing either corn or cotton. I'm thinking it's the fusarium that changed what crops are grown commercially here.
