EVALUATION OF THE EFFECTIVENESS OF DIFFERENT MEANS FOR THE CONTROL OF EGGS, LARVAE AND ADULTS OF P. japonica
In the GESPO project, different types of mulching products (jute, wood chips and coconut fiber) have been tested in nursery pots to limit the oviposition of adult females of P. japonica. None of the tested methods ì provided the total absence of P. japonica larvae in the pots, although the coconut fiber mulching was particularly effective in reducing the presence of larvae in pots.
The efficacy of several chemical and biological insecticide registered for use in pre-mixing with the soil in the nursery for the control of the larval stage was tested. To learn more about the results obtained, please consult the scientific publication at the following link.
The use of commercial and natural strains of entomopathogenic nematodes to reduce larval viability has also been highly effective. To learn more about the results obtained, have a look at the scientific article at the following link.
Nursery pots mulched with coconut fibre used during experiments
In collaboration with MA/AG of Casalbuttano (CR), an experimental sprayer (Eco Defender 25) specialized for the application of insecticides to the ground with low impact on the agronomic characteristics of the soil has been successfully tested.
The use of nets (treated and not-treated with insecticides) and anti-hail nets has been found to be very effective in limiting adult infestations, ensuring the almost total absence of adults within the tested areas. The effectiveness of several chemical and organic products registered in Europe for the management of adult beetles has been evaluated.
