The hair diseased or infected plant of garden of general any of several hot spice plants leads 20 % above, highest amount to 100 % , ill bug index amounts to 30 ~ 50. This disease is in incidence of a disease of high temperature period is high, can cause phloem of ministry of tree dry basis quickly necrotic decay circulates glue fluid, affect nutrition badly to carry, bring about blade etiolation and even whole branch or crown of a tree withered dead, often make one is built before long garden of any of several hot spice plants is destroyed at once. Method of prevention and cure: (1) pest of prevention and cure is invaded catch. Make the prophylaxis and treatment of the insect pest such as bug of fine day ox, Ji Ding in time, protect and enhance tree power, reduce the happening of disease drifting glue, have very good effect.
