Ailanthus or Matti (Ailanthus triphysa)

Pests


Nursery:

The two major pests are shoot webber (Alteva fabriciella) and defoliator (Eligma narcissus). Shoot webber is economically more important because it will damage the terminal shoot and can result in epicormic branch formation. It can be controlled by application of quinalphos at 0.05 per cent.

Young plantations:

The above two are the major pests in young plantations also, but control measures may not be cost effective. If required, 0.1 per cent quinalphos can be applied using rocker sprayer. Shoot webber affects seed production. Usually control measures are not adopted but any insecticide, which is recommended under the nursery, can be used.
