Protection methods

Several protection methods are recommended to control the development of leaf miners on zucchini and squash in France:

• remove and destroy plant debris and crop residues;
• disinfect the substrate reused or soil;
• preheat the greenhouse before planting the plants and carry out an insecticide or acaricide treatment ( e-phy );
• check the sanitary quality of the plants before and during their introduction into the shelter;
• produce the plants in an shelter insect-proof  ;
• 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;
• to use auxiliaries , these are the following insects: Dacnusa sibirica, Diglyphus isaea and Macrolophus caliginosus with, however, a secondary efficacy for the latter;
• consider chemical protection * (r) ( e-phy ), 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.
