Practical Solutions: testing technology in the field

The Practical Solutions in this section were carried under EMPHASIS’ project activities. Here you can review the short summary of the study, get acquainted with its main expectation and results and explore the main practical recommendations. The section provides answer to the questions What is the main added value/benefit/opportunities if the knowledge is implemented? How can a practitioner make use of the scientific results?

Better predators for a better control of whiteflies in greenhouses

Damage of oilseed rape (OSR) in early growth stages by seedling insects (Psylliodes chrysocephala, Phyllotreta spp., Delia radicum, Agriotes lineatus, early season aphid (Myzus persicae) a vector of turnip yellows virus (TuYV), etc.) to EU production is significant. The area of winter or/and spring OSR in some countries is declining as a result of the prohibition period of using neonicotinoids as seed treatment insecticides.

The purpose of the study is to test the efficacy of different mode of action products, provide guidelines, new solutions and IPM methods for OSR protection against seedling insects and alternatives for EU farmers to keep the OSR area, yield levels and honey bee sustainability in this environment.

Insecticide seed treatment is an effective way to protect OSR seedlings from early season insects. The foliar sprays of insecticides are less effective, require 2-7 treatments, are more expensive to the farmer, and have a higher impact on the environment.

Honey bees and other pollinators are an important part of OSR cultivation, agricultural and forestry sector in general. Careful analyses based on facts and growing practices for all involved stakeholders must be done to find solutions for OSR growers and honey bee sustainability.
