Results regarding biological control which replaced chemical control in greenhouses with tomato.
Practical results, obtained in the SC Leoser SA, are presented, replace chemical control with biological control. Thanks to the technology of cultivation substrate "coco peat" and "rockwool", there are no problems of soil pests (wireworms, white worms, gray worms). In recent years we have successfully used products: NESIDIOcontrol (Nesidiocoris tenuis) MACROcontrol (Macrolophus pygmaeus), SWIRScontrol (Amblyseius swirskii) ENCARcontrol (Encarsia formosa), APHI control (Aphidius coleman) PHYTOcontrol (Phytoseiulus persimilis) DIGLY control (Diglyphus isaea) ORIcontrol & MAJUScontrol (Orius laevigatus and O. mayusculus) MONcontrol (Amblyseius montdorensis). Evolution of main pests are presented corelated with biological control measures. Tuta absoluta was successfully controled by mass capture and killing using pheromone traps. The evolution of pest flight expressed by the number of males captured/trap is presented. Presented technology has shown non negative influence on the use of bumblebees for pollination. In case of punctual situation, appearance of problems due to pests, was imposed application of pesticides.
