Abstract Damage to non–dicamba resistant (non-DR) soybean [ Glycine max (L.) Merr.] has been frequent in geographies where dicamba-resistant (DR) and cotton ( Gossypium hirsutum L.) have grown sprayed with the herbicide recent years. Off-target movement field trials were conducted northwest Arkansas determine relationship between dicamba concentration air extent of symptomology on non-DR soybea...

measurement of chlorophyll fluorescence is noninvasive, highly sensitive, fast and easy way to give important information about the photosynthetic apparatus. chlorophyll fluorescence parameters and kautsky curves of wild oat and wild mustard sprayed by clodinafop and dicamba+2, 4-d respectively was investigated at two green house experiments. the results indicated significant reduction at trend...

Abstract Little information is available on the relative efficacy of Group 4 herbicides for glyphosate-resistant (GR) horseweed management in soybean. Five field research experiments were conducted growers’ fields from 2020 to 2021 determine GR control with applied preplant (PP) alone and a mixture. There was minimal soybean injury (≤4%) evaluated. Dicamba, 2,4-D, or halauxifen-methyl PP contro...

The increasing adoption of dicamba-tolerant soybean ( Glycine max ) increases the potential exposure wine grape Vitis sp.) to dicamba, which off-target injury may occur via particle drift or vapor drift. In Missouri, at one site in 2017 and two sites 2018, research production vineyards focused on effects dicamba hybrid ‘Vidal blanc’ grapevines. During flowering early fruit set, bearing grapevin...

Abstract Palmer amaranth has a long history of evolving resistance to herbicides the point at which it become significant obstacle row crop production. A survey escapes in dicamba-resistant cotton and soybean fields Tennessee was conducted fall 2021 with objective determining whether poor control due environmental phenomena or development dicamba resistance. greenhouse dose-response screen on 1...

In view of the widespread increase in herbicide-resistant weeds, biotechnology companies have developed dicamba-tolerant soybean and cotton cultivars. This technology can, however, risk product drifting to adjacent areas. study was with objective evaluate phytotoxicity biometric variables young eucalyptus plants exposed subdoses herbicide dicamba. The experiment carried out under field conditio...

Abstract Dicamba and glufosinate are among the few effective postemergence herbicides to control multiple herbicide-resistant weeds in southeastern U.S. cotton soybean production. Field studies were conducted determine effect of weed size application dicamba individually, mixed, or sequentially on common ragweed, goosegrass, large crabgrass, ivyleaf morningglory, Palmer amaranth, sicklepod cont...

Applications of dicambaherbicide to dicamba-resistant (DR) soybean [Glycine max (L.) Merr.] and cotton (Gossypium hirsutum L.) may increase the risks non-DR exposure dicamba. Dicamba residue in sprayers poses a challenge for applicators that also treat soybean. Risks producers as planted acreage usage DR crops increases, there is potential volatilization herbicide summer months, posing risk nea...

– (Histological changes in banana explants, cv. Nanicão (Musa spp. Group AAA), submitted to different auxins for induction of somatic embryogenesis). The present work analyzes the behavior of banana explants, cv. Nanicão (Musa spp. Group AAA) regarding somatic embryogenesis induction treatments with several auxins. Longitudinal segments of shoot meristematic apices of micropropagated banana pla...
