Go to your local Extension office and ask for Door yard citrus management bullitin. Or check it out on the web. In your search engine type in Florida citrus dooryard

Sprays are pretty useless against leafminers. I've tried everything, even bought a nursery center's entire stock of FertiLome Bagworm, Borer and Leafminer spray.

The only way to keep pristine Citrus leaves, is to do what the pros do. Use a systemic, once a year. Notice the tag on new citrus trees? It indicates when they were treated. No one would buy trees infested with leafminers. The systemic protects against Greening too.

I use Bayer Admire Pro as a yearly soil drench. You can also use Bayer's systemic Tree and Shrub drench from Home Depot(off-label). It is weaker than the Admire Pro, so you will need to use more. It worked great for me, until I bit the bullet and got a bottle of Admire. It is safe for food crops, and is used on nearly all commercial veggie crops grown in Florida.

Now is the time to apply Citrus nutritional sprays, and a fungicide if you see scab or greasy spot. Otherwise, I don't spray my 50 Citrus.

There is a lot of info online about Admire Pro. Please research this product for yourself, so you feel comfortable using it. You are already ingesting it (Imidacloprid) if you eat grocery store produce.

In Citrus, the drench is well taken up in the leaves (effective against leaf predators) but poorly taken up in flowers or fruit. Non-toxic to honeybees, when used as a drench.

Thank You, Gcmastiffs and Fredborn. Will give it a shot. Gotta find out what a "drench" is and am going to go for it. LOL, I really appreciate Everyone's time a effort to help newbees. Peace, Fred#3

I've have an orange, grapefruit and lime for 18 years. Never sprayed them, don't remember ever fertilizing them. They produce alot of fruit with no problems.

Fred#3, a drench is a product mixed with water, in a watering can, that is then applied/poured on the root system of plants. Much easier than spraying.

Atreelady, I don't doubt you have far fewer disease problems in your location. S. Florida Citrus are usually not very pretty, unless treated. But they can produce good fruit when infested by leafminers- it just saps their strength over time, and makes them ugly. The ones I see in my neighbors yards look really bad. They suffer from severe die-back of the branches, scab, sooty mold and leaf miners.
