Abstract EN

The research aimed to identify the extent to which the maize crop is infected with convolvulus arvensis, the ways of its spread, the extent of its development and the reasons for that, and the damage caused by it from the point of view of the respondents, and to identify the level of knowledge and implementation of the respondents of the technical recommendations for the integrated control of convolvulus arvensis in the maize crop, and the diagnosis of determining the system of relative priorities for the technical recommendations affecting the rate of infection of the maize crop with c.arvensis through the assessment of the surveyed farmers for the degree of importance, difficulty and generality of each recommendation, and identifying the most important sources from which the surveyed farmers derive their information, as well as their proposals to improve integrated control methods for c.arvensis in the research area.

the research was conducted in Beheira governorate, and the three districts that are characterized by the cultivation of large areas of the maize crop were selected, namely the district of Abu al-Matamir, Hawsh Issa, and al-Delegat.

three villages were selected as the most infected and damaged by c.

arvensis in the maize crop by a village from each district.

the village of tragi was from the district of Abu al-Matamir, the village of al-Razimat from the district of Hosh Issa, and the village of Sakran from the district of Delengat.

a regular random sample of 285 respondents was selected from a total of 1081 farmers in the selected villages according to the equation (Kreijci and Morgan), and the data was collected using a questionnaire form in the personal interview during the months of September and October 2023, and frequencies, percentages, mean, standard deviation, and range were used in presenting the results.

the most important results were as follows: - the degree of infection of corn crop with c.arvensis is high among 52.6% of the respondents, medium in 27.0%, and low in 20.4% of the respondents.

- 55.4% of the respondents have a low level of knowledge of the technical recommendations for the integrated control of c.arvensis marijuana in the maize crop, 37.2% of them have medium knowledge, and only 7.4% of the respondents have high knowledge.

- 65.3% of the respondents have a low level of implementation of the technical recommendations for the integrated control of c.arvensis marijuana in the maize crop, 28.7% of them are medium implementation, and only 6% of the respondents implement the recommendations to a high degree.

- the most important sources of information for respondents on the integrated control of c.arvensis in the maize crop are agricultural engineers, guidance bulletins, and extension seminars.

- the most important proposals of the respondents to improve the methods of integrated control of c.arvensis in the maize crop are the need to provide information to farmers on the use of specialized herbicides for each crop, the availability of weed control pesticides in the agricultural association, and the need to provide an extension specialist in the field of weed control instead of relying on unqualified pesticide dealers.
