Use of Chlorantraniliprole (CORAGEN 20 SC) for the Control of the Main Cotton Insects in Burkina Faso In seeking alternative molecules to pyrethroids suitable for controlling cottoninsect pests in Burkina Faso, chlorantraniliprole, a molecule of the anthranilic diamide chemical family, was tested in the research station and in the farmers’ fields. In the research station, results obtained showed a good efficacy of chlorantraniliprole at a rate of 20 g.ha-1. Helicoverpa armigera, Anomis flava and Aphis gossypii, compared to untreated plants, were controlled at 95.5 %, 93.6 % and 76 % respectively. This insect control level provided a 18% increase of healthy bolls and provided 65.4 % increase of seed cotton compared to the untreated plants. In the farmers’ fields, the yield gain was 21% by chlorantraniliprole program. This was higher compared to the plants treated with profenofos the reference control applied at the rate of 500g.ha-1. Chlorantraniliprole can therefore be recommended at the rate of 20g.ha-1 to cotton producers to optimize their incomes.
