Houseplant Mealy Bug
The mood of despondency in the house plant grower must by now be almost complete at the prospect of having so many wee heasties crawling about the house. Let me again assert that it would be most unusual and something of a disaster for all these to be present, and the chances are that one is likely to come across nothing more than the occasional attack of greenfly. The foregoing information on pests is intended to make their detection easier and the ensuing advice, it is hoped, will help to keep them under control.
Many of these plant collections are managed extremely well but often enough an incredible infestation of mealy bug will be shrugged off with the comment, ‘Of course, there is a bit of bug about.’ The sad part of it all is that a thorough drenching spray regularly repeated would lead to considerable improvement.
Mealy bug is another pest that may be encountered. Not very particular about which part of the plant he inhabits, he does have a penchant for finding his way between twisting stems and overlapping leaves where he can he particularly inaccessible to any pest control that may be used. One consolation is that mealy bugs are not difficult to see, as they wrap their young in a cotton wool-like substance. Adult bugs are very similar to small wood lice and powdery white in colour.
Another pest that is, fortunately, not so prevalent today is tarsonemid mite. Very minute, invisible to the naked eve, they concentrate their activities mainly on new young growth, ivies being one of their favourite hosts. Distorted and leafless young growth is an indication of their presence. Unfortunately, there is little one can do to eradicate, or even control these pests, as the one effective chemical is highly poisonous and not available to the general public. Drastic though it may appear, the only sensible course when mite presence haS been confirmed is to dispose of the plant, so reducing the chance of the trouble spreading and other plants in the vicinity becoming affected.
A fortune must be spent annually by growers of all sorts of plants in their efforts to keep red spider mite under control, so there is no lack of material when choosing an insecticide with which to treat them. It would be foolish to list the insecticides that are available as they are changing and, we are told, being improved upon all the time. The helpful plant retailer will be the best person to consult in order to obtain advice on the current popular product. Thereafter, follow the manufacturer’s directions, and be sure to thoroughly saturate the undersides of plant leaves. In order to discourage attack from red spider a moist environment should be maintained around the plants and dry atmosphere and arid conditions should be avoided.
Growing plants in difficult, dark locations account for many failures. The symptoms are discolouration and eventual loss of leaves, and production of small leaves on woody, thin stems. In very dark situations new leaves would be something of a luxury.
