Citrus Fruit Problems
Scab disease is primarily a disease of satsuma, grapefruit and lemons.
It does not affect oranges. Scab affects fruit, leaves and young shoots, causing irregular raised corky, scabby wart-like-outgrowths.
Severely scabbed leaves and fruit become misshapen and distorted. The rind of scabbed fruit is thick and puffy. Scab infection occurs on young growth in the spring, copper fungicides, tribasic cooper sulfate or Kocide sprayed after bloom when the fruit is the size of a pea will help control scab. Sooty Mold on Citrus
Sooty mold fungus is not a parasitic organism. It does not penetrate the tissue of the plant, but grows superficially on the honeydew excretions of whiteflies, aphids, mealy bugs and scale insects.
Sooty mold can cause damage by preventing the sunlight from reaching the leaf and by making the fruit black and unattractive. Fruit covered with sooty mold is usually smaller and does not color well.
Control sooty mold indirectly by controlling the insects that excrete the honeydew on which the sooty mold grows.

. Fall Armyworms
Generally in September and October we begin to see damage from fall armyworms in the lawns. We have already had cinch bugs in the lawns this summer.
You need to be on the lookout for the adult moths responsible for the armyworm. The moth is brown in color with a wingspan of 1-1/2 inches. Eggs are laid and many hatch in as little as two days. The larvae can feed for two-three weeks causing severe turfgrass damage.
Fall armyworms larva get up to 1.5 inches long and black striped their entire body. They may be green or black, however, the most distinguishing character is the inverted Y on its head.
Sevin is a good control option as well as bifenthrin (Talstar), halofenozide (March 2, Macho). Talstar and Sevin will control chinch bugs also. Vegetables to Plant in September
Beets, broccoli (transplants or seeds through September) Brussels sprouts (transplants or seeds), cabbage (transplants or seeds), Chinese cabbage (transplants or seeds), cauliflower (transplants or seeds), collards (transplants or seeds), endive, carrots, English peas, snow peas, garlic (late September), kohlrabi, lettuce, mustard, onions (seeds, late September), parsley, snap beans (early September), parsley, snap beans (early September), radishes, rutabaga, shallots, spinach, Swiss chard, turnips and kale.
