| Abstract | ||||
| The goal from these experiments were studied the effect of some chemical and mechanical methods of dodder weed control on the Egyptian clover field. The treatments comprised of spray pendimethalin herbicides (pre-emergence and after sowing) in three concentrations (500,700 and 900 ml/Fed.) and three times application (1, 3 and 7 DAS) followed by spray glyphosate alone after the first cutting in three concentration (50, 70 and 90 ml/Fed.) and three time application (7, 14 and 21 DAS), followed by, studies the influence of addition ammonium sulfate with (1%) on the impact of glyphosate against C. planiflora in Egyptian clover in relation to dose and time of application after the first cutting of Egyptian clover. Phytotoxic of application rates and treatment time of glyphosate on Egyptian clover after the first cutting were studied. Results it could be concluded that, use of pendimethalin at 7 DAS was safe for Egyptian clover T. alexandrinum emergence as compared to its application as pre-emergence at 1 and 3 DAS and also effective in reducing C. planiflora emergence. Moreover, increasing dose of pendimethalin from 500 to 900 ml/Fed. gave significantly decreased in the C. planiflora emergence but also caused phytotoxic to T. alexandrinum plants and reduced its population significantly. Using glyphosate herbicide at different doses were significantly affected the characteristic of dodder plants infested with clover crops. The fresh and dry weights of survival dodder plants were inversely related to the dose of herbicide. The higher the dose of herbicide used the more damage of dodder plants occurred.The mechanical methods -hand combing- management was the minimum effective in C. planiflora control with percent of reduction. | ||||
