Effect of sowing methods and control treatments on dodder clover crop [electronic resource].

Includes reference.

Two field experiments were carried out at sakha experimental station during 2004/2005 and 2005/2006 seasons 10 investigate the effect of different sowing methods (dry method and dry method after false irrigation) and some herbicides i.e. glyphosate, butralin, imidazolin, bentazon, propyzamide and hand combing treatment on controlling dodder weed Cuscuta planinora and growth of clover plants Trifolium alexandrinum L Results indicated that the hand combing treatment and different sowing methods were not enough in dodder control, but it used only as a help factor in control program. Also, the results indicated that bulralin herbicide showed good control of dodder under the sowing after false irrigation, followed by propyzamide, glyphosate. imidazolin and bentazon treatments. Also, showed that the parasitic weed dodder caused a great reduction in fresh weight of clover plants. Clover piants infected with dodder showed that the lowest contents of chlorophyll a. b and total Chlorophyll compared with healthy plants. Data also cleared that all tested herbicides showed least effective on chlorophyll content Also, showed the that the reduction percentage Of chorophyll content was increased by increasing the time of treatment.
