Method for preventing and controlling trialeurodes vaporariorum or Westwood of greenhouse pseudo-ginseng by utilizing planted galinsoga parviflora for trapping

Abstract

The invention provides a method for preventing and controlling trialeurodes vaporariorum or Westwood of greenhouse pseudo-ginseng by utilizing planted galinsoga parviflora for trapping. The method comprises the steps of adopting a way of planting the galinsoga parviflora in a greenhouse pseudo-ginseng planting area in a stripped shape, wherein the pseudo-ginseng is sowed at first, and 20 days after the pseudo-ginseng is sowed, the galinsoga parviflora is sowed; starting to monitor whether or not the trialeurodes vaporariorum or Westwood is trapped on plants of the galinsoga parviflora after seedlings of the galinsoga parviflora emerge; starting to eliminate the trialeurodes vaporariorum or Westwood trapped on the plants of the galinsoga parviflora when it is monitored that the trialeurodesvadporariorum or Westwood is trapped on the plants of the galinsoga parviflora. By means of the method, the tropism of the trialeurodes vaporariorum or Westwood on the galinsoga parviflora is utilized, so that the trialeurodes vaporariorum or Westwood is trapped on the galinsoga parviflora, and then the trialeurodes vaporariorum or Westwood on the galinsoga parviflora is centralizedly eliminatedto reduce the population quantity of the trialeurodes vaporariorum or Westwood on the pseudo-ginseng. Not only are effective prevention and control over the trialeurodes vaporariorum or Westwood on the pseudo-ginseng achieved, but also pesticide safety problems brought by chemical prevention and control over the trialeurodes vaporariorum or Westwood are solved, and therefore, the method for preventing and controlling the trialeurodes vaporariorum or Westwood on the pseudo-ginseng is efficient, quick and green.

Description

technical field [0001] The application belongs to the technical field of greenhouse whitefly control, and in particular relates to a method for preventing and controlling greenhouse whitefly from Panax notoginseng by trapping and trapping Hyssopus chinensis. Background technique [0002] The temperature and humidity conditions of Panax notoginseng are very suitable for the reproduction and growth of the greenhouse whitefly (Trialeurodesvaporariorum or Westwood). Greenhouse whitefly feeds on plant sap as adults and nymphs, causing chlorosis, yellowing, and wilting of infected leaves, resulting in the death of the entire plant. Greenhouse whitefly has become an important pest that seriously affects the yield and quality of Panax notoginseng due to its strong fecundity, fast reproduction, large population and flock damage. [0003] In the prior art, chemical pesticides are usually used to control the greenhouse whitefly. Since the greenhouse whitefly is easy to develop resist...

AI Technical Summary

Problems solved by technology

Since greenhouse whitefly is easy to develop resistance to chemical pesticides, frequent use of chemical pesticides will promote the development of insecticide resistance

On the other hand, Panax notoginseng is an excellent Chinese herbal medicine, and a large amount of chemical pesticides are used in the planting process of Panax notoginseng, resulting in pesticide residues in the harvested Panax notoginseng, which is harmful to human health
