| Abstract |
The objective of this work is to design an integrated bollworm management program on cotton . The obtained results indicated that :
1 -The cotton seed treatment with Gausho caused the lowest average infestation percentages by pink and spiny bollworms in the green bolls ( 4 .2 and 4.1 % ) and also caused the highest production of cotton seed yield ( 7.6 and 8.6 Kent . / Fed ) during 2000 and 2003 seasons .
2 -The effect of planting dates 30 / 3 and 15 / 4 exhibted the lowest infestation by bollworms ( 7.0 and 7.5 %)in the first season . While, in the second season recorded 3.5 and 3.6 % and produced the highest cotton seed yield ( 8.1 and 8.5 Kent ./ Fed ., respectively ) .
3 - The fertilization treatment rate at 150 Kg ( NPK ) recorded the lowest average percent of infestation ( 5.3 %) and cotton seed yield ( 8.3 Kent . / Fed ) but lower and higher fertilization recorded the same average percent infestation during the first season . While during the second season the average percent of infestation was 4.6 % and produced the highest cotton seed yield 9.8 Kent. / Fed.
4 - Planting distance of 80 cm between rows and 20 cm between hill recorded the lowest average percent infestation 4.4 % Also , recorded the highest cotton seed yield 8.6 and 9.4 Kent . / Fed during the two seasons .
5 - The results of interaction between the different treatments clarifed that the planting date on 30/3 ; fertilization with 200 and 150 KG. NPK /Fed. , 70 and 80 cm between rows , one plant in hill and 10 cm. between hill recorded lower infestation with the cotton bollworms which ranged between 3.4 -5.1 %, and higher cotton seed yield ranged between 10 - 11 Kent./Fed.
