Abstract

The invention relates to the field of prevention and control of diseases and insect pests, in particular to a method for preventing and controlling insect pests of dendrobium officinale. The method comprises the following steps of (1) medium treatment, wherein every one weak, a prevention and control solution A is sprayed to a dendrobium medium; (2) dendrobium treatment, wherein every 5 d, a prevention and control solution B is sprayed to dendrobium plants; the prevention and control solution A and the prevention and control solution B are sprayed to the medium and dendrobium, the insect pestsof dendrobium are prevented and controlled to the greatest degree, the average incidence rate of the insect pests of the dendrobium officinale plants is controlled to be about 4.5%, the total effective rate of dendrobium officinale attacked by the insect pests is controlled to be 95% or above, and the prevention and control effect is obvious. By means of the method, the dendrobium officinale plants cannot be damaged, the adopted prevention and control solutions A and B have abundant nutrients, necessary nutrients can be provided for the growth of dendrobium, and the growth of dendrobium is effectively promoted while the insect pests are prevented and controlled.

Problems solved by technology

[0003] In view of the rich nutritional value and medicinal value of Dendrobium officinale, it has a very high plantability, so it is planted in all provinces of my country. With the extension of the planting period and the expansion of the area, various pests will increase. The common pests are spider mites. , aphids, whiteflies, mole crickets, etc., mainly attack the roots, stems, and leaves of Dendrobium, causing serious damage. At present, for insect pests, predatory mites, light trapping, or artificial hunting are generally used, but the traditional treatment methods have no significant control effect , and will also cause a series of problems such as a certain degree of impact on the growth of Dendrobium, so the effective control of insect pests during planting of Dendrobium is the focus of current research
