ADAMA launches Trivor insecticide against Greening vector psyllid in Brazil

Amid the phytosanitary crisis affecting citrus orchards in Brazil, ADAMA presented a new solution during Expocitros 2024, with special coverage by AgroPages.

Developed for controlling the psyllid (Diaphorina citri), the insect vector of the bacteria causing greening or huanglongbing (HLB), the Trivor insecticide (Acetamiprid + Pyriproxyfen) targets all stages of the pest. Currently, the costs for psyllid control represent 15% of the expenses for Brazilian citrus growers, a percentage considered extremely high due to the importance of containing this pest, which has been devastating the industry. The psyllid, measuring 2 to 3 millimeters, transmits the bacteria Candidatus Liberibacter spp., the causal agent of greening, the worst disease affecting citrus farming today, both in Brazil and other producing regions such as Florida in the USA.

"Greening is a disease that requires the complete eradication of the contaminated area because it cannot be controlled," says Raphael Malandrino, agronomist and Insecticides Product Manager at ADAMA. In the United States and in the interior of São Paulo, he explains, the pest has already destroyed various orchards, directly impacting the urban consumer market. "On one hand, we have the pest pressure, and on the other, the risk of resistance due to successive applications of products with the same modes of action," he explains. 

In this scenario, the ADAMA Insecticides Product Manager asserts that Trivor serves as a "fundamental tool for citrus farming." According to him, the new insecticide stands out by controlling all stages of the psyllid, from eggs to adult insects, thereby breaking the pest's reproductive cycle.

"There are few commercial actives currently available, and the resistance problem is recurring. With the new solution, we offer another effective option to producers for rotating active ingredients, a crucial strategy to preserve the lifespan of these products," Malandrino emphasizes. The citrus sector as a whole is extremely concerned and engaged in combating this unprecedented phytosanitary crisis.

Brazil is the world's largest producer and exporter of oranges, making citrus farming a strategic and priority crop for the national agribusiness.

Trivor is certified by ProteCitros, a program developed by Fundecitros (Citrus Defense Fund-Fundecitrus), for use in orchards with fruits destined for export.
