Protection methods

  

Several protection methods are recommended to control the development of whiteflies on zucchini in France:

  • treat plants before uprooting in the presence of high pest populations;
  • check the sanitary quality of the plants before and during their introduction into the shelter;
  • produce the plants in an shelter insect-proof ;
  • install canvases insect-proof at shelter openings;
  •  weed the greenhouse and its surroundings;
  • detect the first pests thanks to the yellow sticky panels placed above the crop as soon as the plants are introduced;
  • use auxiliaries such as the insects Encarsia formosa, Eretmocerus eremicus (these two insects are especially effective on Trialeurodes vaporariorum, Eretmocerus mundus - mainly effective on Bemisia tabaci ) and Macrolophus caliginosus and the fungi Paecilomyces fumosoroseus and Verticillium lecanii (note that its effectiveness may vary from one strain to another);
  • reason the chemical protection (r) (e-phy whiteflies, Trialeurodes vaporariorum and Bemisia tabaci ) *, in particular if you use auxiliaries.

(r): resistance to insecticides or acaricides is known in these pests. 
* Chemical control : The number of pesticides available for a given use is constantly changing, we advise you to always confirm your choice by consulting the e-phy site of the Ministry of Agriculture and Fisheries which is a catalog in line of plant protection products and their uses, fertilizers and growing media approved in France. This also applies to all biological products based on microorganisms or natural substances.
