ANTIRRHINUM INSECTS
ANTIRRHINUM INSECTS
Aphids feed on terminal growth and the undersides of the leaves. The insects suck juices, and heavy infestations seriously weaken the plants. Aphids are controlled with sprays of rotenone, acephate, or applications of Diazinon dust.
The greenhouse leaf tier chews irregular shaped areas in the leaves and webs the leaves together. Pesticides are seldom effective after the insect rolls the leaves. No chemical control is listed.
Mites cause a bronzed or stippled appearance on the foliage, especially in hot weather. Use rotenone according to label directions.
