Confirm 2F and Tracer as an Useful Alternative For Ipm Against Boll Worm, Tobacco Budworm and Beet Armyworm in Cotton in Northern Mexico

Arturo Obando-Rodr¡guez, Sostenes Delgado-Garc¡a and Juan Solis-Rea


Control of bollworm, tobacco budworm, and beet armyworm larvae was tested in Northern Mexico in Chihuahua State, Delicias, City under experimental conditions from July to September 1997 with the insect growth regulator insecticide Confirm 2F and Tracer (spinosad), a result of bacteria fermentation and its class is Naturalyte. Both bioinsecticides are novel products and enviromentally safe. Confirm 2F was applied under experimental conditions to cotton at 500, 750, and 1000 cc/ha and Tracer at 125 cc/ha. Confirm 2F had good and fast control of bollworm and budworm larvae (See table 7). L1 – L2 were killed 3 to 5 days after treament by the 3 Confirm 2F dosages. Tracer had better control since it killed all larvae 3 days after treatment. However, L3 larvae (see table 8) were killed within 5-8 days by Confirm 2F. Larvae L4-L6 needed 8-15 days to be affected (Table 9).
