Treatment

Kerosene emulsion; tobacco decoction and extracts.

Clover Mite (Bryobia Pratensis)

Small reddish mites attacking the leaves, causing them to turn yellow.

Treatment

Lime-sulfur while trees are dormant. In summer, use self-boiled lime-sulfur, as a dust, or sulfur paste.

Flat-Headed Borer

See Apple.

Fruit Tree Black Beetle (Scolytus Rugulosus)

A small beetle similar to the peach tree bark-beetle.

Treatment

Same as for Peach Tree Bark-Beetle, which see.

Katydid

This insect is often troublesome to the peach in the southern states in the early spring, eating the leaves and girdling young stems.

Remedy

Poisoned baits placed about the tree.

Green Peach-Louse Or Aphis (Myzus Persicae)

A small insect feeding upon the young leaves, causing them to curl and die.

Treatment

Lime-sulfur, kerosene emulsion, or tobacco extract. After the buds open, either of the last two.

Peach Tree Bark-Beetle (Phloetribus Liminaris)

A dark brown beetle one-tenth inch in length burrowing under the bark.

Treatment

Burn all brush and worthless trees as soon as the infestation is observed. Keep the trees in healthy condition by thorough cultivation and the use of fertilizers. Apply a thick whitewash to the trunk and branches three times a season: (1) the last week of March, (2) second week in July, (3) first week in October.

Peach Tree-Borer (Sanninoidea Exitiosa)

A whitish larva, about 3/4 inch long when mature, boring into the crown and upper roots of the peach, causing gum to exude.

Remedies

Dig out the borers in June and mound up the trees. At the same time apply gas-tar or coal-tar to the trunk from the roots up to a foot or more above the surface of the ground.

Peach Twig-Moth (Anarsia Lineatetta)

The larva of a moth, 1/4inch long, boring in the ends of the shoots, and later in the season attacking the fruit. Several broods.

Remedy

Spray with lime-sulfur just after the buds swell. Spray trunks and larger branches in late spring to kill first brood pupae in the curls of bark.

Plum-Curculio (Conotrachelus Nenuphar)

This insect may be successfully controlled on peach by spraying with arsenate of lead, four pounds to one hundred gallons of self-boiled lime-sulfur. Spray, first, when the "husks" drop from the fruit; second, ten days or two weeks later. It is unsafe to spray peaches more than twice with arsenate of lead.

Red-Spider, Or Mite (Tetranychus Bimaculatus)

A small mite infesting many plants, both in the greenhouse and out-of-doors. It flourishes in dry atmospheres, occurring on the under sides of the leaves. In some forms it is reddish, but usually light-colored and two-spotted. Common.

Remedies

Persistent syringing with water will generally destroy them, if the spray is applied to the under surface. Use lots of force and little water to avoid drenching the beds. Sulfur and water. Dry sulfur. On orchard trees, flour paste.
