Postemergence control of smooth crabgrass in lawn turf

Postemergence control of smooth crabgrass in lawn turf. Cisar, John L.; Jagschitz, John A. (Plant Sci. Dep., Univ. Rhode Island, Kingston, RI 02881, USA). Proc. Annu. Meet. Northeast. Weed Sci. Soc., 38, 276-80 (English) 1984. CODEN: PNWSBF. ISSN: 0078-1703. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Postemergence herbicides were evaluated in 3 lawn areas (Kentucky bluegrass, red fescue, and perennial ryegrass-red fescue) for effective control of smooth crabgrass (Digitaria ischaemum). Parameters tested included treatment rates, no. of applications, time interval between treatments, gallonage effects, and use of adjuvants. Effectiveness was based on crabgrass control (90-100% was considered excellent) and turf injury scores. MSMA [2163-80-6] over a range of parameters provided excellent and safe control in all turf areas, but in some cases caused objectionable injury. HOE-A25-01 [66441-23-4] at some rates (e.g., 0.175 lb/acre) gave excellent control in all turf areas without causing objectionable injury. DSMA [144-21-8] provided good results in Kentucky bluegrass, but injured the red fescue and perennial ryegrass-red fescue lawns. EH-697 [89370-70-7], CGA-82725 (I) [72280-52-5], and DOWCO 453 ME [69806-40-2] gave excellent control under certain conditions and at times caused objectionable turf injury. Sethoxydim [74051-80-2] controlled crabgrass, but severely thinned perennial ryegrass. HOE-00583, SC-1084, DPX-Y6202-14, fluazifop-Bu, and DOWCO 356 were ineffective when tested under a limited range of conditions.Except for chemicals metioned above, 2163-80-6 and 72280-52-5 are also used. .

Studies on the Rhizoctonia large patch of Zoysia turfgrass

Studies on the Rhizoctonia large patch of Zoysia turfgrass. IV. Influence of spraying of several herbicides on outbreak of this disease. Kobayashi, Katashi (King Chem.Some commonly used reagents like 741-58-2 and 1861-32-1 are used in this experiment. K. K., Japan). Shibakusa Kenkyu, 11(2), 173-82 (Japanese) 1982. CODEN: SHIKDG. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Applications of CAT [122-34-9], SAP [741-58-2], siduron [1982-49-6], TCTP [1861-32-1], butamifos [36335-67-8], propyzamide [23950-58-5], or orthobencarb [34622-58-7] to Zoysia turfgrass at recommended rates in the spring and autumn prior to Rhizoctonia outbreak did not increase the susceptibility of turfgrass to the disease. Application of MCPP [7085-19-0] and asulam [3337-71-1] after lesion development did not affect infection, whereas DSMA [144-21-8] inhibited spread of the disease. .
