Toggle navigation. Abstract Tropical spiderwort is an exotic, invasive weed in the southern USA that has become one of the most troublesome cotton weeds in Georgia and Florida. Due to the continuous emergence pattern of tropical spiderwort, successful management will require a multi-component approach that includes an effective herbicide with soil residual activity. Field studies were conducted in Georgia and North Carolina to evaluate the effectiveness of several preemergence herbicides in suppressing tropical spiderwort emergence.

Most of Georgia's cotton is glyphosate resistant GR , and glyphosate is only marginally effective on tropical spiderwort. An experiment was conducted at four locations to determine tropical spiderwort control in GR cotton by 27 herbicide systems. Treatments consisted of three early-postemergence over-the-top POT herbicide options and nine late-postemergence-directed LPD options arranged factorially. Pyrithiobac improved control of emerged spiderwort, whereas S-metolachlor provided residual control.
Dimethipin mixed with glyphosate did not improve control. Bibliographic information. Language : English. Type : Journal Article. Volume : Issue : 2. Start Page : End Page : All titles : " Tropical spiderwort Commelina benghalensis control in glyphosate-resistant cotton ".

Managing Commelina Species: Prospects and Limitations
Commelina species, notably C. There are - species reported in the family Commelinaceae [ 50 ]. Recent data indicates that the Commelinaceae family contains 23 genera and at least species native to or naturalized in the New World and 23 genera and about species in the Neotropics [ 41 ] and also website reports of 50 genera and species [ 16 , 31 ]. There are species of Commelina in the warmer regions of the world and 50 species of Murdannia occurring in the tropics and warm temperate regions worldwide with Tropical Asia having the greatest diversity [ 17 ].
