There are a couple of online resources that may help you.
The first thing I would try is from the University of Arizona. Give it a try next time you have a problem.
Cornell University (New York) has a plant pathology department with some good online resources also. While some of the information won't apply to Arizona gardeners it is an interesting resource.
You can find the website at
The first signs are faint yellow bands on the upper surfaces of the leaves. The bottom of the leaf becomes dotted with tiny gray specks. The mildew isn't harmful to humans but it looks unattractive. You can remove the infected leaves and make sure the plants has good air circulation. Fungicides don't seem to be very effective. Some varieties of basil seem to be more susceptable than others. Lemon and purple basil's seem to resist it better than sweet and Thai basil.

Let me know if you see this in your garden.

Grasshoppers can be voracious eaters of just about everything. There are chemical controls but they need to be applied correctly for your safety and the best result. An easier solution may be to just cover your plants temporarily with a physical barrier. Lightweight spun fabrics (like Remay and others) are very good at protecting your plants from grasshopper damage. A bait is available (Nosema locustae
). The bait needs to be applied in the spring as it is most effective on the nymphs, juvenile grasshoppers, that hatch in the spring. The problem with the bait is that it needs to be applied to a large area. If you live on a small city lot, it won't provide much protection as grasshoppers can move long distances.
