The formulation is registered. The permitted uses are for avian control. Use is only for the Direction of Plant Protection and Conditioning (DPVC).
Granivorous birds are migratory pests that constitute a major concern for grain farmers in Chad. This avian threat puts the population in a state of permanent food insecurity despite the government's efforts in its last intervention of seven teams in May 2009 and that obliged the Ministry of Agriculture and Irrigation through the DPVC to organize in 2011 and 2012 a mission composed of four (4) teams, three (3) of which were charged with survey and control and the fourth charged with supplies and monitoring.
The DPVC has used:
- In 2009: 112 liters to treat 45 nests for a total of 59 hectares in ten (10) days for one (1) hour per day and by 6 land teams at a dose of 1.8 liters/ha;
- In 2011: 105.5 liters to treat 16 nests for a total of 54.7 hectares in thirty (30) days for one (1) hour per day and by 3 land teams at a dose of 1.9 liters/ha;
- In 2012: 275 liters to treat 25 nests for a total of 53 hectares in thirty (30) days for one (1) hour per day and by 3 land teams at a dose of 3 liters/ha.
In 2011, the mission lasted forty-five (45) days for the teams in charge of survey and control; and fifteen (15) days for the team in charge of supply and monitoring, from 6 June to 21 July 2011.
It was in the course of that avian control mission that a technician, 60 years of age and who had had a long history of hypertension (the technician had hypertension but did not signal it to the DPVC when he departed on the control campaign) was intoxicated in a nest situated 200 km from N'Djaména (Boroko) on the date of 17 June 2011.
Description of incidents related to the problem, including the adverse effects and the way in which the formulation was used:
The technician took part both in filling and application. He was wearing protective clothing during the whole operation: he wore a protective kit comprising a hat, glasses, mask, a cotton overall, gloves and boots covered by trousers.
The effects were observed 1 hour after application. The intoxicated person presented the following symptoms: vomiting, abundant salivation and titubation one hour after application.
He was immediately brought to Bokoro hospital, then moved to the emergency department of N'Djaména hospital where he received further care. On the advice of the doctor, he was discharged the same day for home care. Unfortunately, despite the care at home, he relapsed on the fourth day and passed away.
Regulatory, administrative or other measure taken, or intended to be taken, by the proposing Party in response to such incidents:
The product will be used pending the development of other alternatives such as traditional trapping nets.
