Experimental results with Belem®, new granular insecticide for the control of Western Corn Rootworm and wireworms.
The Western Corn Rootworm and wireworms represent today key pests for corn cultivation in Northern Italy, where they cause important crop damages. In this paper are presented the results of 6 efficacy trials to evaluate the efficacy of a new soil insecticide Belem® (granular cypermethrin) against wireworms and the Western Cora Rootworm. The product was applied at sowing through a novel distribution technology that improves the product efficacy. The innovation is a Carp-Tail DXP® diffuser at the terminal part of the distribution channel that guarantees a more uniform distribution and a bigger soil surface contact, compared to the normal distribution of granular insecticides with current sowing machines. The trial results confirm that the new product Belem, used with the new application kit Carp-Tail DXP at the dose rate 12 kg/ha, can reduce significantly the damages caused by the above soil insects.
