摘要

Orobanche aegyptica. (Egyptian broomrape) is a parasitic weed that causes serious yield reductions in tomato crop (Lycopersicon esculentum) with no effective method being warranted for its control. Thus, in 2005-06 growing season, greenhouse and field experiments were conducted to evaluate the possibility of selective, chemical control of broomrape in tomato. Both experiments were arranged as a randomized complete blocks design with four replications. Treatments included application of chlorsulfuron at 7.5 g a. i./ha (either applied soil incorporated or through irrigation water), glyphosate at 20.5, 30.75, 41 and 61.5 g a. i./ha, rimsulfuron at 2.5, 5, 7.5,15 and 30 g a. i./ha post-emergence, sulfosulfuron at 25, 50 and 100 g a. i./ha post emergence and trifluralin at 960 (only in greenhouse study) or 1200 g a. i./ha PPI and 1200 g a. i./ha HERB. Broomrape infested and non-infested controls were also included. Sulfosulfuron applied at 50 and 100 g a. i./ha were the most effective treatments in terms of both O. aegyptica control and particularly fruit yield. Mean per cent yield increase from these treatments was more than 100%. Glyphosate applied at 61.5 g a. i./ha (in greenhouse experiment) or at any rates (in field experiment) provided approximately the complete control of O. aegyptica but due to the crop injury fruit yield was not improved. A similar result was found for chlorsulfuron applied at 7.5 g a. i./ha HERB. Rimsulfuron applied at 7.5 g a. i./ha resulted in markedly high yields under both greenhouse and field conditions but O. aegyptica control was only satisfactory in field experiment.
