Too much rain causing plant diseases

-A A +A


What a difference a year makes. We have had too much rain and if you ride around you can see crops turning yellow and wilting and there isn’t anything we can do. Personally I have even had a few perennials and pepper plants give up as well and I live on a high windy location that drains well.
Diseases are starting to run rampant as well especially bacterial blight because it needs water or wet leaves to propagate and it sure has had that!
Peppers are generally the most affected by bacterial blight and if you have a variety that doesn’t have any resistance then you need to spray to control it. Fixed copper mixed with mancozeb or a product containing chlorothalonil will do the trick but you will have to respray after each rain.
Also diseases in turf grasses are showing up as well, such as brown patch. Turf diseases are generally caused by too much nitrogen and too much water. We can’t do anything about the water and for this season if too much nitrogen we can’t do much either but for future reference if you have brown patch cut back on fertilizer applications. I recommend only one fertilizer application per season done in November or December. This keeps the turf looking nice and you not mowing three times a week!  
Brown patch generally doesn’t require treatment on established lawns and generally clears up when the weather dries. However, there are fungicide applications that can be made if you just can’t stand the spots. This can be expensive and is best done by professionals.
Fruit crops are becoming infected with diseases as well. It is pretty much too late to control tree fruit diseases if you didn’t start early to limit infection but if you want to give it a try fruit tree spray is your best option.
Grapes have black rot, anthracnose, powdery mildew, and downy mildew. Unless you are a commercial wine grape grower or have done preventive sprays there isn’t much you can do now. A cover spray or two of mancozeb or a product containing chlorothalonil might limit the infections a bit. Bramble crops have a little anthracnose but nothing that is going to limit harvest at this point.
Again after harvest is complete mancozeb and chlorothalonil will help the new growth. With all the water also comes a lot of growth and squash, zucchini, and cucumbers are producing like crazy. If they had more caloric value we could feed the world with the stuff.
I have eaten squash and zucchini just about every way you can have it and if you have any unusual way to prepare it give me a call and I will give you a shout out with the recipe posted in my newsletter, Facebook, and maybe even the newspapers. Happy gardening!
