Need to know what you're treating before fungicide can be suggested.

Also need to verify if it's disease

The local Ag. agency wants $40 to analyze a sample. I thought they were tax supported.

garf, if you can post a few pictures, people on this forum can probably identify your problems. Do you have a master gardener's program in your county/city? If so, they might be able to help you if you bring diseased leaves in a bag. Alternatively, some good nurseries or garden centers also offer this service. Especially since they get to sell you sprays if they can tell you what disease you have.

No problem.

Spraying the combination of my leftover Maneb and Neem oil seems to have arrested whatever was killing my plants. There are a few plants that have something else wrong, so I need to concentrate on that now.

I have had similar tomato problems on a semi-annual basis. I use a Neem oil product with limited success. What are the dangers associated with copper? I rinse all my veggies prior to consumption. Has anyone had success with Captan?
~Thanks~
