| Abstract/Contents: | "The objectives of this research were to compare several premixed 2,4-D ester combinations to 2,4-D amine for weed control in turf. The most effective formualtion will then be used as a standard in furture research to compare with new herbicide combinations. The results are a completion of data from several braodleaf herbicide studies conducted at the Virginia Tech Turfgrass Research Center in Blacksburg, VA. Areas of "Rebel" tall fescue and several varieties of Kentucky bluegrass were fertilized at .45 kg of N/90 m2 using a 10-10-10 fertilizer. Plots, 183 X 183 cm, were mowed to a height of 5 cm and irrigated as needed. Herbicides were applied with a bicycle sprayer at 23 psi with 8003 nozzles at 475 1 ha-1. Each study was set-up as a randomized complete block with 3 reps and analyzed by the Waller-Duncan's multiple range test. The combinations of 2,4-D plus dichlorprop had the most frequent difference in control between the ester and amine formulation. Common dandelion, curly dock and yellow woodsorrel were better controlled by the ester formulation then the amine formulation of 2,4-D plus dichlorprop. However, with addition of dicamba to the 2,4-D plus dichlorprop combination, there was no difference found between treatments except in the control of mouseear chickweed. Here again the ester formulation gave the better control. The ester formulation of 2,4-d plus triclopyr also gave higher control of common dandelion and yellow woodsorrel than did the amine formulation. When the 2,4-D plus triclopyr rates were increased there was no difference found between formulations. Control of cinquefoil and mouseear chickweed was excellent with all combinations. 2,4-D combined with dichlorprop or with dichlorprop plus dicamba gave very poor control of corn speedwell compared to excellent control with 2,4-D plus triclopyr. Yellow woodsorrel and common dandelion were best controlled by both the ester formulations of 2,4-D plus triclopyr and 2,4-D plus dichlorprop. In all cases in which 2,4-D amine and ester differed, 2,4-D ester afforded more complete control. Of the three 2,4-D ester combinations observed, 2,4-D plus triclopyr was found to give good control of the most weeds rated. Therefore, since 2,4-D ester plus triclopyr had the broadest spectrum of common broadleaf weed control in turf this combination will be considered for further research along with commonly used 2,4-D plus dicamba." |
