pumpkin squash blight

Asked August 6, 2015, 9:21 PM EDT

I have had tomato blight in my garden I plan on not planting any tomatoes for three years after I have removed and destroyed all the tomato vines. Is there any correlation from tomato blight to blight that appears on my pumpkins squash and cucumber vines? What can I do to remove the blight completely from my garden and prevent it from appearing again?. I was told that I received the blight from tomato plants that were infected and imported from other countries is that true? Thank you

We are guessing that your tomato plant had late blight or anthracnose. Big box stores and other stores get their vegetable seedlings from lots of places in the country and it is possible that they could come from out of the US. These seedlings could be infected with diseases such as late blight. The organism that causes late blight in tomatoes can also affect pumpkins. https://extension.umd.edu/growit/anthracnose-vegetables To keep anthracnose from overwintering, it is a good idea to get rid of all infected plant material.

Now that I do have the late blight I will remove and destroy all the vines is there anything I can do to treat the soil for next year's crop to prevent this from happening again?

You do not need to treat the soil, but be sure to remove all plant material. vw
