The research aimed to determining the level of knowledge and implemention needs of respondents farmers to the practices of rationalizing use of chemical pesticides in the control of tomato pests, in addition to determine the correlation and regression relationship between independent variables of respondents and the degree of knowledge and implemention need to practices of rationalizing the use of chemical pesticides for it, also identifying extension services Provided by the agricultural extension to rationalize the use of chemical pesticides in control of tomato pests, finally identifying the problems facing the respondents farmers when rationalizing the use of chemical pesticides in control of tomato pests from their point of view.

The study data were collected by using the questionnaire with the personal interview during the March and April 2020, it was used frequency and percentages, arithmetic mean, the standard deviation, simple correlation coefficient of Pearson, chi square, and multiple regression analysis step-wise used to analyze the studied data.

The main research results are summarized as follows: - The majority of respondents farmers (80% ) were located in medium and high knowledge need categories of practices of rationalizing the use of chemical pesticides in contro of tomato pests.

- The majority of respondents farmers (89.2% ) came in the category of medium implemention need for rationalization practices of the use of chemical pesticides in the control of tomato pests.

- There is a significant relationship at the level of 0.01 between: age, educational level, practice of farm work, size of agricultural tenure, cultivated area of tomato, number of years of experience in tomato cultivation, number of guiding seminars, degree of satisfaction with tomato cultivation and knowledge need degree to practices of rationalization of the use of chemical pesticides in control of tomato pests, .

- It was also evident that the extension services provided by the extension agency were weak to rationalize the use of chemical pesticides in combating tomato pests.
