Flocks of birds, especially sparrows, visited the greenhouse regularly. In addition to damaging crops, the birds spread bacteria and soiled the greenhouse with droppings. The destruction they caused equated to an annual financial loss of approximately 12,000 euros.
• 100% reduction in bird activity
• Damage to the greenhouse completely eliminated
• Annual losses in the fruit and vegetable fields decreased from 7.5 tonnes to 0
• Bacteria pressure was reduced in the field monitored by the Agrilaser Autonomic, and in an adjacent field
New Zealand Gourmet, a premier grower of high-quality fruits and vegetables achieved a 100% reduction in bird activity at their Taupo, NZ greenhouse with the installation of the Agrilaser Autonomic
Sparrows exhibited a tendency to nest in the tomato and capsicum crops within the New Zealand Gourmet greenhouse, and demonstrated a particular fondness for Campari tomatoes. Bird activity at the operation, which covers two houses, 5 and 6 ha, respectively, was constant from dusk till dawn. Roelf Schreuder and his colleagues tried numerous methods to get rid of the birds, including poisoning them with baits and catching them with semi-invisible nets. The birds soon became accustomed to the nets and learned to avoid the poison, and continued to cause significant financial loss by spreading bacteria and damaging the fruits and plants.
Roelf learned about Bird Control Group from an industry associate in Auckland who recommended the Agrilaser Autonomic. Roelf was initially skeptical about the possible effectiveness of the technology, but decided to test it on the 5 ha area dedicated to tomatoes. Roelf programmed the Agrilaser for active monitoring from sunrise till sunset, and the results were astonishing: the greenhouse realized a 100% reduction in bird numbers after only a few months of using the Agrilaser, and the damage caused by birds was completely eliminated.
“The Agrilaser was the best investment to get rid of the birds and save up to 7.5 tonnes of fruits each year!”
Based on the results New Zealand Gourmet achieved, Roelf Schreuder has expressed a strong belief in the potential for Bird Control Group’s products in the New Zealand market. The technology can benefit small farmers as well as large agricultural operations, all of which can attain a long-term, sustainable solution for their bird problem.
