Abstract
The purpose of phytomedicine nowadays is ecologically acceptable protection against plant diseases that is attained by reducing standard chemical plant protection applying preventive protection measures and the newest achievements in biological control. Application of biological products can be given advantage specially in protected areas and in organic production, when replacing chemicals that become inefficient due to the resistance development, and on account of pesticide residues present. In gerbera production the use of insecticides obligatory throughout and to decrease their use and inhalation toxicity, especially during periods of high temperatures, application and introduction of biological pest and disease control is highly recommended. In this investigation predator wasp (Encarsia formosa) for whitefly (Trialeurodus vaporariorum) and the combination of 50% Encarsia formosa and 50% Eretmocerus eremicus in gerbera glasshouse production and parasite fungus (Trichoderma harzianum) for the control of fungus diseases Pythium debarianum and Rhizoctonia solani, agents of seedling lodging in greenhouse tomato production were used and compared with the use of standard chemical pesticides. At the end of the experiment, in both cases, biological control gave the best result.
