The event, held in Ifapa-Las Torres in Seville on March 28, brought together companies and entities from the cirtus sector.
The red spider (Tetranychus urticae) is an mite that frequently reaches population levels of plague in a wide range of horticultural, citrus, vitivinicultural, fruit and ornamental crops. Its high capacity for proliferation and dispersion, its short life cycle and the existence of colonies with silks that prevent the correct penetration of pesticides are factors that determine a rapid emergence of resistance in this species. In areas where agricultural roads are sandy in nature or have been mixed with very fine soil or with gravel and a lot of dust rises, with the usual transfer of agricultural vehicles and machinery, it is adhering in large quantities, and constantly , on the cobwebs formed by the red spider, which prevents the correct penetration of the active materials and further enhances its ability to generate new resistance.
The application of the Dustex product on agricultural roads has been shown to reduce the effect of the proliferation of the red spider pest in citrus crops, by minimizing the presence of dust generated by the transit of vehicles and machinery.
In the report on the evaluation of the efficacy of Dustex for the control of the problem of red spider dust in citrus cultivation, prepared by researchers Estefanía Romero Rodríguez, Francisco J. Arenas Arenas and Javier Quinto Cánovas of Ifapa Centro Las Torres and presented by the latter, it was revealed that only in the treatment with the Dustex product (in front of the control treatments and the spray of road with water) the threshold of economic damage was not exceeded (> 54% of outbreaks occupied by the red spider pest). Another very interesting fact is that the use of acaricides is significantly more effective in Dustex treatment due to the lower presence of dust in crops. Finally, another note is that, after the application of these two-three passes of acaricide, only in the Dustex treatment the levels of presence of the pest were lower even than those present at the beginning of the crop.
Before this intervention, Ángel Leo-Revilla, CEO of Agrointec, explained in broad strokes the business lines of the company that, as a consultancy and technological engineering for the agri-food sector, has in one of its strategic pillars the collaboration with private entities and public, such as IFAPA with which he is currently working on projects in three Andalusian provinces, to obtain new innovative applications of products such as Dustex in the agricultural sector.
After this first intervention, Rafael Sánchez as head of the Plant Health Service of the Ministry of Agriculture, explained the citrus surveillance plan.
Subsequently, Alfonso Lucas Espadas, a specialist technician with extensive experience in the Plant Health Service of the Region of Murcia, defined in detail the main pests that affect citrus fruits as well as their main cultural tasks to eradicate them. Lucas placed special emphasis on biological control strategies.
José Luis Rodríguez explained the current status of thePhytosanitary Surveillance Network (RAIF) platform and, in particular, for the monitoring of citrus mites in Andalusia.
Thomas Stauder, marketing manager of Borregaard Ibérica, broadly defined the history and strategic lines of his company as well as the use and particularities that, to date, has been given to Dustex.
