Types of Garden Enemies
The return to rose is made in early fall. There are several other aphid species on roses, and they are often responsible for more puckering and deformation of buds than they are given credit for. Buds sometimes have a white streak down the petals. I get excellent control of aphids on rose with the pyrethrum and rotenone contained in Tri-ogen, a three-in-one combination rose spray. Some report good results with lindane, and old Black Leaf 40 is not to be sneezed at.

ROOT APHIDS.
The aster root aphid (Anuraphis middletont), corn root aphid (A. maidi-radicis), and tulip bulb aphid {A. tulipae) all work on plant roots, causing yellowing and wilting of the tops. They are small, bluish green covered with a white powder, and are fostered by ants who collect aphid eggs in the fall, store them in their nests over winter, and then return the young nymphs to plant roots in spring. The tulip bulb aphid is rather common on stored gradiolus corms as well as tulip and narcissus bulbs.

Control. Use chlordane to control the ants. When roots are already infested, make a depression around the base of the plant and pour in a solution of lindane or nicotine. Use nicotine dust for stored bulbs.

ROSY APPLE APHID (Anuraphis roseus).
Apple leaves are curled and young fruit deformed by rose-colored lice covered with white wax. A dormant dinitro spray for the egg stage or TEPP just before or after bloom is reported effective.

SNOWBALL APHID (Anuraphis viburnicold).
Everyone who grows the common snowball must be familiar with the tight curling of young leaves. A dormant spray followed by frequent spraying as leaves are coming out is supposed to give control, but I've never had much luck. It might be easier to replace Viburnum opulus with V. tomentosum which resists aphid injury.

WOOLLY APPLE APHID
(Eriosoma lanigerum). Common on apple, also attacks pear, hawthorn, mountain-ash, and elm. White cottony masses covering purple lice are formed on trunk and branches, knots on roots. Young trees sometimes die. Spray with lindane.

ARMYWORMS
Armyworms are related to cutworms, the larvae of moths. They usually feed at night but sometimes migrate and feed by day. They are most injurious to field crops but sometimes are garden and lawn pests. They work in large groups, armies.

ARMYWORM
(Cirphis unipuncta). Dark-green caterpillars, smooth, about 154 inches long, with white stripes along sides and back, hide during the day under clods or stones or at base of plants. They feed on all grass crops, especially corn, and fluctuate in abundance from year to year. There are 2 or 3 generations a year in the North. Control. Spray the infested lawn or other area with chlordane, using 1 tablespoon 50% wettable powder to a gallon of water, or apply 5% chlordane dust, or 5 to 10% DDT dust, or 2% lindane.
