| Abstract/Contents: | "A rainfall simulator was used to evaluate the effects of washoff on 10 foliar-applied herbicides on johnsongrass [Sorghum halepense (L.) Pers. #3 SORHA] in greenhouse experiments during 1983 and 1984 at Stoneville, MS. Time intervals between herbicide application and rainfall ranged from 20 to 240 min. Johnsongrass topgrowth control was equivalent to rain-free treatments using DPX-Y6202 {ethyl [2-[4-(6-chloro-2-quinozalinyl) oxy] phonosy] propionate} at 0.03 and 0.06 kg/ha at time periods of >90 and >40 min between herbicide application and rainfall, respectively, at 28 days after treatment (DAT). A period of >120 min. was required for johnsongrass control equivalent to rain-free treatments using sethoxydim }2-]1-(ethoxyimino) butyl] -5-[2-(ethylthio) propyl] -3- hydroxy-2-cyclohexen-1-one} at 0.06 kg/ha, haloxyfop {2-[4-[[3-chloro-5-(trifluoromethyl) -2-pyridinyl] oxy] phenoxy] propanoic acid} at 0.03 and 0.06 kg/ha, and clopryxydim {(E,E-2- [1-[[(3-chloro-2-propenyl) oxy] imino] butyl]-5-[2-ethyl-thio) propyl]-3-hydroxy-2-cyclohexen-1-one} at 28 DAT. Neither glyphosate [N-(phosphonomethyl) glycine] and SC-0224 (trimethylsulfoniumcarboxy methylaminomethylphosphonate) at 0.45 and 0.99 kg/ha nor other selective herbicides at 0.03 and 0.06 kg/ha gave equivalent johnsongrass top-growth control to rain-free treatments when rainfall occurred within 240 and 120 min, respectively." |
