What can be used to clear blight from tomato plants?

Only a couple of my plants have withered, but want to prevent this from damaging any more tomatoes.. any help would be apprediated.. thanks!

The most common is Septoria leaf spot, which appears toward the end of July. It first appears as small round black or brown lesions on the lower leaves. It works its way up the plant starting at the bottom.

The second most common is Early blight. It appears about the same time as Septoria, and is characterized by concentric "target" shaped lesions.

The least common but most destructive is late blight. It usually appears in August and the first symptoms are watery lesions on the lower leaves. Late blight will destroy an entire crop within a week.

The prevalence of these blights is affected by seasonal conditions and varies greatly from year to year. Heirloom tomatoes seem more susceptible.

Septoria does not usually affect the fruit. We have gotten very large crops of excellent tomatoes even on plants with a substantial infection.

The most effective way to treat tomato blights is to prevent them. Here is a list of do's and don'ts:

* Mulch to prevent splash-up from rain.
* Don't water overhead.
* Don't water in the evening.
* Give your plants plenty of space.
* Don't work around your plants when they are wet.
* Don't plant tomatoes in the same place where tomatoes, potatoes, peppers or eggplants were grown last year.
* Clean up all debris in the fall and don't compost it.
* Prune out diseased branches promptly and destroy.
* Keep weeds at a minimum.
* Plant resistant varieties when available.

These recommendations are especially important if your crop has late blight. In that case, skip planting tomatoes, peppers, potatoes or eggplant in the same location for at least one season.

It will greatly reduce the Septoria in tomatoes by using landscape fabric as a mulch. It can be purchased at garden centers.

Using fungicides for tomato blights is not generally recommended. By the time gross symptoms appear on your plants, it is too late to apply a fungicide. If you do use a fungicide, you must use it at the very first sign of the disease.

I like Ortho multi purpose fungicide (Daconil 2787) or any other product containing chlorothalonil. It is a preventative spray and will keep the disease from spreading to more leaves.

For blight you need a fungicide. For worms you need Sevin dust.

Blight is a fungus and requires a fungicide to get rid of it. When in doubt, keep a product from called Ferti-lome called Triple Action. This is a spray product contains a Herbicide, a an insecticide, and a fungicide.

When you are unsure what is the problem with your plant, hit w/this.

Seven Dust, and lime is good too
