| Abstract | ||
| the present investigation was conducted to evaluate six control programs in reducing the incidence of pink bollworm on cotton crop at Zagazig district, Sharkia Governorate during 2013 and 2014 seasons. Results indicated that the highest reduction percentages of the pink bollworm, Pectinophora gossypiella (Sounders) were 85.65 and 83.90 % with programs E and C, respectively during 2013. Meanwhile in the second season, it was 85.19 and 83.31 % with program E and C, respectively. The highest yield production was 1260.00 and 1157.00 kg/fed was recorded for E and C programs during the 2013 season, while it was 1088.00 and 1056.00 kg/fed. was recorded for E and C programs during 2014 season; compared with 630.00 and 610.00 kg/fed of the untreated plots during the 2013 and 2014 cotton seasons, respectively. Finally, it could be concluded that the best insecticidal programs were E and C, results showed that those programs revealed the lowest infestation percentages of the pink bollworm larvae and yield production increase. | ||
