Control Of Broomrape (Orobanche ramosa L.) By Using Two (Herbicides) And One Natural Product (Neem Leaves Powder) On Tomato Crop

Abstract

This study was conducted at the Agricultural Research Corporation farm, Shambat in the season 2004-2005 .this study aimed for control of the parastic flowering plant Orobanche ramosa . on tomato plant The herbicides used were Goal at two does (1.9 ml/L -1.5/L ml) and Pursuit at two doses 1 ml/ L – 0.5 ml /L) .Neem leaves at two doses (10 gm / hole – 20 / hole ) . In three replicates The results revealed that there were significant differences on Orobanche ramosa on number of Orobanche / plants and number of branches although effect on fresh and dry weights compared to control .The yield of tomato (number and weight of fruits) had been decreased by treatments of chemicals. Goal herbicide at two rates tested was not effective in controlling Orobanche ramose these as pursuit at two rates tested were significantly effective in decrease the number of Orobanche ramose/plant and the shoots of orobanche/plant Neem leaves powder on the other land also decreased the number of shoots of orobanche the effect of both pursuit herbicide and Neem leaves on the fresh weight and dry weight also significantly low compared to control. Goal herbicide also did not affect the fresh weight or dry weight of orobanche yield of tomato was significantly increased over the control in pursuit herbicides treatments and Neem leaves powder Goal herbicides at two rates tested did not increased Tomato yield compared to control .
