Abstract/Contents:"Residual affects of chlordane, polychlorodicyclopentadiene isomers (Bandane), diphenatrile and trifluralin were studied by applying the herbicides to prepared seedbeds and seeding at different intervals following herbicide application. Turf species used were Kentucky bluegrass, Chewings fescue and tall fescue. In another experiment chlordane, Bandane, diphenatrile, trifluralin, DMPA (Zytron), and DCPA (Dacthal) were applied at different rates to established Kentucky bluegrass turf in fall, winter and spring applications to evaluate possible phytotoxic effects and effectiveness for crabgrass control. Chlordane applied at 71.5 pounds per acre caused a reduction in emergence of Kentucky bluegrass but did not significantly affect emergence of Chewings fescue and tall fescue when seedings were made three days after treatment. Bandane applied at 40 pounds per acre significantly reduced emergence of Kentucky bluegrass, Chewings fescue and tall fescue when seedings were made three days after treatment. Both Bandane and chlordane caused little or no reduction at 17 days and subsequent seeding dates after treatment and the above rates. Trifluralin applied at five pounds per acre caused a reduction in emergence of Kentucky bluegrass when seedings were made 54 days after treatment while diphenatrile applied at 40 pounds per acre reduced emergence at date of treatment and 20 days later, but caused reduction at later seeding dates. Chlordane, Bandane, Dacthal and diphenatrile showed no toxic effects on established Kentucky bluegrass when applied as fall winter, and spring treatments at the respective rates of 71.5, 40, 10 and 40 pounds per acre. Trifluralin and Zytron at the respective rates of five and 20 pounds per acre showed some toxicity to established Kentucky bluegrass. Chlordane, Bandane, Dacthal, Zytron and trifluralin treatments resulted in very effective control of crabgrass during the season in which applied, but levels of crabgrass control dropped off significantly in the second season when no subsequent application was made."
