Abstract:
Residual effect of eight herbicides (pendimethalin, pretilachlor, triasulfuron, ethoxysulfuron, pyrazosulfuron-ethyl, carfentrazone-ethyl, 2,4-D amine and carfentrazone-ethyl + isoproturon) applied in strip –tilled wheat (Triticum aestivum L.) on the succeeding crop i. e mungbean (Vigna radiate L.), jute (Corchorus capsularis L.) and sunflower (Helianthus annus L.) were investigated during 2013-14 and 2014-15 cropping season in Old Brahmaputra Flood plain, Bangladesh through bio assay techniques. Results of two years study revealed that germination and crop growth of these succeeding crops were not affected by any of the herbicides residue applied in wheat. Leaf chlorophyll and crop dry matters of the succeeding crops were also not influenced from herbicide residue. Somewhat, shoot lengths of mungbean and sunflower were increased in the herbicide treated plots but root lengths of some herbicide treated plots were decreased at a negligible rate compare to the control one. Therefore, residual effect study claimed that use of the tested herbicides in strip-tilled wheat is safe for germination and growth of the succeeding crops like mungbean, jute and sunflower and farmer can grow these crops in a rotation with strip-tilled wheat.
