DOGWOOD SPOT ANTHRACNOSE
{Elsinoe corni), recently injurious from Maryland to Florida. The spots are both small and numerous, tan with purple or brown borders on flower bracts, grayish with reddish margins on leaves. Tissue in center of leaf spots sometimes drops out. Small, light cankers may also appear on stems.

Control. Preliminary work indicates that infection can be reduced by new fungicides such as Manzate and captan without leaf injury.

PECAN SPOT ANTHRACNOSE
{Elsinoe randii), nursery blight, on pecan in Southeast. Small reddish leaf lesions, turning to ash gray; diseased tissue becoming brittle and falling out. Several sprays of low-lime bordeaux mixture have been used in nurseries.

ROSE SPOT ANTHRACNOSE
(Sphaceloma rosae), more frequent on climbing roses than on bush roses pruned back each year. Leaf spots are more or less circular, with light centers, often showing fruiting bodies as numerous black dots, and reddish margins. Spots on canes are sometimes elongated, slightly raised. Spores are spread by splashing rain, and the fungus overwinters on canes.

Control. Sprays or dusts containing sulfur, copper, or Fermate as used for black spot should be effective for spot anthracnose.

ANTS
Ants, relatives of bees and wasps, belong to the insect order Hymenoptera. They have a much constricted abdomen which is joined to the thorax by a pedicel, and the antennae are hinged like an elbow. They are social insects, living in colonies in the ground or decaying wood. An ant colony has one or two queens, who spend their lives laying eggs, and thousands of sterile, wingless workers who feed the queens and tend the maggot larvae.

CORNFIELD ANT
(Lasius niger alienus americanus), a native found over most of the United States. This brown ant is small, not over 1/10 inch long, and makes small single or clustered mounds in open soil or on lawns. It also distributes root aphids, caring for them in return for the sweet honeydew.

Control. Treat individual hills with chlordane, applying 1/8 teaspoon 50% wettable powder to center of mound, watering well afterward, or pour a suspension of 1 ounce of chlordane emulsion to a gallon of water into nests. Aldrin and dieldrin are now approved for ant control. Follow directions on the label, and soak the lawn heavily after treatment to reduce hazard to children and pets. Keep them away from the lawn until it is completely dry.
